+
+ The Mappable mixin is designed for classes that would like to
+ behave as a map for configuration purposes.
+
+ For example, the DS.Adapter class can behave like a map, with
+ more semantic API, via the `map` API:
+
+ DS.Adapter.map('App.Person', { firstName: { keyName: 'FIRST' } });
+
+ Class configuration via a map-like API has a few common requirements
+ that differentiate it from the standard Ember.Map implementation.
+
+ First, values often are provided as strings that should be normalized
+ into classes the first time the configuration options are used.
+
+ Second, the values configured on parent classes should also be taken
+ into account.
+
+ Finally, setting the value of a key sometimes should merge with the
+ previous value, rather than replacing it.
+
+ This mixin provides a instance method, `createInstanceMapFor`, that
+ will reify all of the configuration options set on an instance's
+ constructor and provide it for the instance to use.
+
+ Classes can implement certain hooks that allow them to customize
+ the requirements listed above:
+
+ * `resolveMapConflict` - called when a value is set for an existing
+ value
+ * `transformMapKey` - allows a key name (for example, a global path
+ to a class) to be normalized
+ * `transformMapValue` - allows a value (for example, a class that
+ should be instantiated) to be normalized
+
+ Classes that implement this mixin should also implement a class
+ method built using the `generateMapFunctionFor` method:
+
+ DS.Adapter.reopenClass({
+ map: DS.Mappable.generateMapFunctionFor('attributes', function(key, newValue, map) {
+ var existingValue = map.get(key);
+
+ for (var prop in newValue) {
+ if (!newValue.hasOwnProperty(prop)) { continue; }
+ existingValue[prop] = newValue[prop];
+ }
+ })
+ });
+
+ The function passed to `generateMapFunctionFor` is invoked every time a
+ new value is added to the map.

+
+ An adapter can save one-to-many relationships by embedding
+ IDs (or records) in the parent object. In this case, the
+ relationship is not considered acknowledged until both the
+ old parent and new parent have acknowledged the change.
+
+ In this case, the adapter should keep track of the old
+ parent and new parent, and acknowledge the relationship
+ change once both have acknowledged. If one of the two
+ sides does not exist (e.g. the new parent does not exist
+ because of nulling out the belongs-to relationship),
+ the adapter should acknowledge the relationship once
+ the other side has acknowledged.
+
+ ### Separate Entity
+
+ An adapter can save relationships as separate entities
+ on the server. In this case, they should acknowledge
+ the relationship as saved once the server has
+ acknowledged the entity.

+/**
+ A serializer is responsible for serializing and deserializing a group of
+ records.
+
+ `DS.Serializer` is an abstract base class designed to help you build a
+ serializer that can read to and write from any serialized form. While most
+ applications will use `DS.JSONSerializer`, which reads and writes JSON, the
+ serializer architecture allows your adapter to transmit things like XML,
+ strings, or custom binary data.
+
+ Typically, your application's `DS.Adapter` is responsible for both creating a
+ serializer as well as calling the appropriate methods when it needs to
+ materialize data or serialize a record.
+
+ The serializer API is designed as a series of layered hooks that you can
+ override to customize any of the individual steps of serialization and
+ deserialization.
+
+ The hooks are organized by the three responsibilities of the serializer:
+
+ 1. Determining naming conventions
+ 2. Serializing records into a serialized form
+ 3. Deserializing records from a serialized form
+
+ Because Ember Data lazily materializes records, the deserialization
+ step, and therefore the hooks you implement, are split into two phases:
+
+ 1. Extraction, where the serialized forms for multiple records are
+ extracted from a single payload. The IDs of each record are also
+ extracted for indexing.
+ 2. Materialization, where a newly-created record has its attributes
+ and relationships initialized based on the serialized form loaded
+ by the adapter.
+
+ Additionally, a serializer can convert values from their JavaScript
+ versions into their serialized versions via a declarative API.
+
+ ## Naming Conventions
+
+ One of the most common uses of the serializer is to map attribute names
+ from the serialized form to your `DS.Model`. For example, in your model,
+ you may have an attribute called `firstName`:
+
+ ```javascript
+ App.Person = DS.Model.extend({
+ firstName: DS.attr('string')
+ });
+ ```
+
+ However, because the web API your adapter is communicating with is
+ legacy, it calls this attribute `FIRST_NAME`.
+
+ You can determine the attribute name used in the serialized form
+ by implementing `keyForAttributeName`:
+
+ ```javascript
+ keyForAttributeName: function(type, name) {
+ return name.underscore.toUpperCase();
+ }
+ ```
+
+ If your attribute names are not predictable, you can re-map them
+ one-by-one using the `map` API:
+
+ ```javascript
+ App.Person.map('App.Person', {
+ firstName: { key: '*API_USER_FIRST_NAME*' }
+ });
+ ```
+
+ ## Serialization
+
+ During the serialization process, a record or records are converted
+ from Ember.js objects into their serialized form.
+
+ These methods are designed in layers, like a delicious 7-layer
+ cake (but with fewer layers).
+
+ The main entry point for serialization is the `serialize`
+ method, which takes the record and options.
+
+ The `serialize` method is responsible for:
+
+ * turning the record's attributes (`DS.attr`) into
+ attributes on the JSON object.
+ * optionally adding the record's ID onto the hash
+ * adding relationships (`DS.hasMany` and `DS.belongsTo`)
+ to the JSON object.
+
+ Depending on the backend, the serializer can choose
+ whether to include the `hasMany` or `belongsTo`
+ relationships on the JSON hash.
+
+ For very custom serialization, you can implement your
+ own `serialize` method. In general, however, you will want
+ to override the hooks described below.
+
+ ### Adding the ID
+
+ The default `serialize` will optionally call your serializer's
+ `addId` method with the JSON hash it is creating, the
+ record's type, and the record's ID. The `serialize` method
+ will not call `addId` if the record's ID is undefined.
+
+ Your adapter must specifically request ID inclusion by
+ passing `{ includeId: true }` as an option to `serialize`.
+
+ NOTE: You may not want to include the ID when updating an
+ existing record, because your server will likely disallow
+ changing an ID after it is created, and the PUT request
+ itself will include the record's identification.
+
+ By default, `addId` will:
+
+ 1. Get the primary key name for the record by calling
+ the serializer's `primaryKey` with the record's type.
+ Unless you override the `primaryKey` method, this
+ will be `'id'`.
+ 2. Assign the record's ID to the primary key in the
+ JSON hash being built.
+
+ If your backend expects a JSON object with the primary
+ key at the root, you can just override the `primaryKey`
+ method on your serializer subclass.
+
+ Otherwise, you can override the `addId` method for
+ more specialized handling.
+
+ ### Adding Attributes
+
+ By default, the serializer's `serialize` method will call
+ `addAttributes` with the JSON object it is creating
+ and the record to serialize.
+
+ The `addAttributes` method will then call `addAttribute`
+ in turn, with the JSON object, the record to serialize,
+ the attribute's name and its type.
+
+ Finally, the `addAttribute` method will serialize the
+ attribute:
+
+ 1. It will call `keyForAttributeName` to determine
+ the key to use in the JSON hash.
+ 2. It will get the value from the record.
+ 3. It will call `serializeValue` with the attribute's
+ value and attribute type to convert it into a
+ JSON-compatible value. For example, it will convert a
+ Date into a String.
+
+ If your backend expects a JSON object with attributes as
+ keys at the root, you can just override the `serializeValue`
+ and `keyForAttributeName` methods in your serializer
+ subclass and let the base class do the heavy lifting.
+
+ If you need something more specialized, you can probably
+ override `addAttribute` and let the default `addAttributes`
+ handle the nitty gritty.
+
+ ### Adding Relationships
+
+ By default, `serialize` will call your serializer's
+ `addRelationships` method with the JSON object that is
+ being built and the record being serialized. The default
+ implementation of this method is to loop over all of the
+ relationships defined on your record type and:
+
+ * If the relationship is a `DS.hasMany` relationship,
+ call `addHasMany` with the JSON object, the record
+ and a description of the relationship.
+ * If the relationship is a `DS.belongsTo` relationship,
+ call `addBelongsTo` with the JSON object, the record
+ and a description of the relationship.
+
+ The relationship description has the following keys:
+
+ * `type`: the class of the associated information (the
+ first parameter to `DS.hasMany` or `DS.belongsTo`)
+ * `kind`: either `hasMany` or `belongsTo`
+
+ The relationship description may get additional
+ information in the future if more capabilities or
+ relationship types are added. However, it will
+ remain backwards-compatible, so the mere existence
+ of new features should not break existing adapters.

+/**
+ The REST adapter allows your store to communicate with an HTTP server by
+ transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
+ should use the REST adapter.
+
+ This adapter is designed around the idea that the JSON exchanged with
+ the server should be conventional.
+
+ ## JSON Structure
+
+ The REST adapter expects the JSON returned from your server to follow
+ these conventions.
+
+ ### Object Root
+
+ The JSON payload should be an object that contains the record inside a
+ root property. For example, in response to a `GET` request for
+ `/posts/1`, the JSON should look like this:
+
+ ```js
+ {
+ "post": {
+ title: "I'm Running to Reform the W3C's Tag",
+ author: "Yehuda Katz"
+ }
+ }
+ ```
+
+ ### Conventional Names
+
+ Attribute names in your JSON payload should be the underscored versions of
+ the attributes in your Ember.js models.
+
+ For example, if you have a `Person` model:
+
+ ```js
+ App.Person = DS.Model.extend({
+ firstName: DS.attr('string'),
+ lastName: DS.attr('string'),
+ occupation: DS.attr('string')
+ });
+ ```
+
+ The JSON returned should look like this:
+
+ ```js
+ {
+ "person": {
+ "first_name": "Barack",
+ "last_name": "Obama",
+ "occupation": "President"
+ }
+ }
+ ```

+ Defines the properties that will be concatenated from the superclass
+ (instead of overridden).
+
+ By default, when you extend an Ember class a property defined in
+ the subclass overrides a property with the same name that is defined
+ in the superclass. However, there are some cases where it is preferable
+ to build up a property's value by combining the superclass' property
+ value with the subclass' value. An example of this in use within Ember
+ is the `classNames` property of `Ember.View`.
+
+ Here is some sample code showing the difference between a concatenated
+ property and a normal one:
+
+ ```javascript
+ App.BarView = Ember.View.extend({
+ someNonConcatenatedProperty: ['bar'],
+ classNames: ['bar']
+ });
+
+ App.FooBarView = App.BarView.extend({
+ someNonConcatenatedProperty: ['foo'],
+ classNames: ['foo'],
+ });
+
+ var fooBarView = App.FooBarView.create();
+ fooBarView.get('someNonConcatenatedProperty'); // ['foo']
+ fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
+ ```
+
+ This behavior extends to object creation as well. Continuing the
+ above example:
+
+ ```javascript
+ var view = App.FooBarView.create({
+ someNonConcatenatedProperty: ['baz'],
+ classNames: ['baz']
+ })
+ view.get('someNonConcatenatedProperty'); // ['baz']
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
+ Adding a single property that is not an array will just add it in the array:
+
+ ```javascript
+ var view = App.FooBarView.create({
+ classNames: 'baz'
+ })
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
+
+ Using the `concatenatedProperties` property, we can tell to Ember that mix
+ the content of the properties.
+
+ In `Ember.View` the `classNameBindings` and `attributeBindings` properties
+ are also concatenated, in addition to `classNames`.
+
+ This feature is available for you to use throughout the Ember object model,
+ although typical app developers are likely to use it infrequently.

+ An ArrayProxy wraps any other object that implements `Ember.Array` and/or
+ `Ember.MutableArray,` forwarding all requests. This makes it very useful for
a number of binding use cases or other cases where being able to swap
out the underlying array is useful.
A simple example of usage:
- var pets = ['dog', 'cat', 'fish'];
- var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
- ap.get('firstObject'); // => 'dog'
- ap.set('content', ['amoeba', 'paramecium']);
- ap.get('firstObject'); // => 'amoeba'
+ ```javascript
+ var pets = ['dog', 'cat', 'fish'];
+ var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
+
+ ap.get('firstObject'); // 'dog'
+ ap.set('content', ['amoeba', 'paramecium']);
+ ap.get('firstObject'); // 'amoeba'
+ ```
This class can also be useful as a layer to transform the contents of
an array, as they are accessed. This can be done by overriding
`objectAtContent`:
- var pets = ['dog', 'cat', 'fish'];
- var ap = Ember.ArrayProxy.create({
- content: Ember.A(pets),
- objectAtContent: function(idx) {
- return this.get('content').objectAt(idx).toUpperCase();

- ap.get('firstObject'); // => 'DOG'
+ ```javascript
+ var pets = ['dog', 'cat', 'fish'];
+ var ap = Ember.ArrayProxy.create({
+ content: Ember.A(pets),

is to pass through any methods or properties to the underlying array. This
capability comes from `Ember.ArrayProxy`, which this class inherits from.
- Note: As of this writing, `ArrayController` does not add any functionality
- to its superclass, `ArrayProxy`. The Ember team plans to add additional
- controller-specific functionality in the future, e.g. single or multiple
- selection support. If you are creating something that is conceptually a
- controller, use this class.
+ Sometimes you want to display computed properties within the body of an
+ `#each` helper that depend on the underlying items in `content`, but are not
+ present on those items. To do this, set `itemController` to the name of a
+ controller (probably an `ObjectController`) that will wrap each individual item.

+ For example:
+
+ ```handlebars
+ {{#each post in controller}}
+ <li>{{title}} ({{titleLength}} characters)</li>
+ {{/each}}
+ ```
+
+ ```javascript
+ App.PostsController = Ember.ArrayController.extend({

+ });
+ ```
+
+ In some cases it is helpful to return a different `itemController` depending
+ on the particular item. Subclasses can do this by overriding
+ `lookupItemController`.

+ For example:
+
+ ```javascript

+/**
+ `Ember.View` is the class in Ember responsible for encapsulating templates of
+ HTML content, combining templates with data to render as sections of a page's
+ DOM, and registering and responding to user-initiated events.
+
+ ## HTML Tag
+
+ The default HTML tag name used for a view's DOM representation is `div`. This
+ can be customized by setting the `tagName` property. The following view
+class:
+
+ ```javascript
+ ParagraphView = Ember.View.extend({
+ tagName: 'em'
+ });
+ ```
+
+ Would result in instances with the following HTML:
+
+ ```html
+ <em id="ember1" class="ember-view"></em>
+ ```
+
+ ## HTML `class` Attribute
+
+ The HTML `class` attribute of a view's tag can be set by providing a
+ `classNames` property that is set to an array of strings:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNames: ['my-class', 'my-other-class']
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view my-class my-other-class"></div>
+ ```
+
+ `class` attribute values can also be set by providing a `classNameBindings`
+ property set to an array of properties names for the view. The return value
+ of these properties will be added as part of the value for the view's `class`
+ attribute. These properties can be computed properties:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['propertyA', 'propertyB'],
+ propertyA: 'from-a',
+ propertyB: function(){
+ if(someLogic){ return 'from-b'; }
+ }.property()
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view from-a from-b"></div>
+ ```
+
+ If the value of a class name binding returns a boolean the property name
+ itself will be used as the class name if the property is true. The class name
+ will not be added if the value is `false` or `undefined`.
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['hovered'],
+ hovered: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view hovered"></div>
+ ```
+
+ When using boolean class name bindings you can supply a string value other
+ than the property name for use as the `class` HTML attribute by appending the
+ preferred value after a ":" character when defining the binding:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['awesome:so-very-cool'],
+ awesome: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view so-very-cool"></div>
+ ```
+
+ Boolean value class name bindings whose property names are in a
+ camelCase-style format will be converted to a dasherized format:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['isUrgent'],
+ isUrgent: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view is-urgent"></div>
+ ```
+
+ Class name bindings can also refer to object values that are found by
+ traversing a path relative to the view itself:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['messages.empty']
+ messages: Ember.Object.create({
+ empty: true
+ })
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view empty"></div>
+ ```
+
+ If you want to add a class name for a property which evaluates to true and
+ and a different class name if it evaluates to false, you can pass a binding
+ like this:
+
+ ```javascript
+ // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
+ Ember.View.create({
+ classNameBindings: ['isEnabled:enabled:disabled']
+ isEnabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view enabled"></div>
+ ```
+
+ When isEnabled is `false`, the resulting HTML reprensentation looks like
+ this:
+
+ ```html
+ <div id="ember1" class="ember-view disabled"></div>
+ ```
+
+ This syntax offers the convenience to add a class if a property is `false`:
+
+ ```javascript
+ // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
+ Ember.View.create({
+ classNameBindings: ['isEnabled::disabled']
+ isEnabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view"></div>
+ ```
+
+ When the `isEnabled` property on the view is set to `false`, it will result
+ in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view disabled"></div>
+ ```
+
+ Updates to the the value of a class name binding will result in automatic
+ update of the HTML `class` attribute in the view's rendered HTML
+ representation. If the value becomes `false` or `undefined` the class name
+ will be removed.
+
+ Both `classNames` and `classNameBindings` are concatenated properties. See
+ `Ember.Object` documentation for more information about concatenated
+ properties.
+
+ ## HTML Attributes
+
+ The HTML attribute section of a view's tag can be set by providing an
+ `attributeBindings` property set to an array of property names on the view.
+ The return value of these properties will be used as the value of the view's
+ HTML associated attribute:
+
+ ```javascript
+ AnchorView = Ember.View.extend({
+ tagName: 'a',
+ attributeBindings: ['href'],
+ href: 'http://google.com'
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <a id="ember1" class="ember-view" href="http://google.com"></a>
+ ```
+
+ If the return value of an `attributeBindings` monitored property is a boolean
+ the property will follow HTML's pattern of repeating the attribute's name as
+ its value:
+
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',
+ attributeBindings: ['disabled'],
+ disabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <input id="ember1" class="ember-view" disabled="disabled" />
+ ```
+
+ `attributeBindings` can refer to computed properties:
+
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',
+ attributeBindings: ['disabled'],
+ disabled: function(){
+ if (someLogic) {
+ return true;
+ } else {
+ return false;
+ }
+ }.property()
+ });
+ ```
+
+ Updates to the the property of an attribute binding will result in automatic
+ update of the HTML attribute in the view's rendered HTML representation.
+
+ `attributeBindings` is a concatenated property. See `Ember.Object`
+ documentation for more information about concatenated properties.
+
+ ## Templates
+
+ The HTML contents of a view's rendered representation are determined by its
+ template. Templates can be any function that accepts an optional context
+ parameter and returns a string of HTML that will be inserted within the
+ view's tag. Most typically in Ember this function will be a compiled
+ `Ember.Handlebars` template.
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('I am the template')
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">I am the template</div>
+ ```
+
+ Within an Ember application is more common to define a Handlebars templates as
+ part of a page:
+
+ ```html
+ <script type='text/x-handlebars' data-template-name='some-template'>
+ Hello
+ </script>
+ ```
+
+ And associate it by name using a view's `templateName` property:
+
+ ```javascript
+ AView = Ember.View.extend({
+ templateName: 'some-template'
+ });
+ ```
+
+ Using a value for `templateName` that does not have a Handlebars template
+ with a matching `data-template-name` attribute will throw an error.
+
+ Assigning a value to both `template` and `templateName` properties will throw
+ an error.
+
+ For views classes that may have a template later defined (e.g. as the block
+ portion of a `{{view}}` Handlebars helper call in another template or in
+ a subclass), you can provide a `defaultTemplate` property set to compiled
+ template function. If a template is not later provided for the view instance
+ the `defaultTemplate` value will be used:
+
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default'),
+ template: null,
+ templateName: null
+ });
+ ```
+
+ Will result in instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">I was the default</div>
+ ```
+
+ If a `template` or `templateName` is provided it will take precedence over
+ `defaultTemplate`:
+
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default')
+ });
+
+ aView = AView.create({
+ template: Ember.Handlebars.compile('I was the template, not default')
+ });
+ ```
+
+ Will result in the following HTML representation when rendered:
+
+ ```html
+ <div id="ember1" class="ember-view">I was the template, not default</div>
+ ```
+
+ ## View Context
+
+ The default context of the compiled template is the view's controller:
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
+ });
+
+ aController = Ember.Object.create({
+ firstName: 'Barry',
+ excitedGreeting: function(){
+ return this.get("content.firstName") + "!!!"
+ }.property()
+ });
+
+ aView = AView.create({
+ controller: aController,
+ });
+ ```
+
+ Will result in an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">Hello Barry!!!</div>
+ ```
+
+ A context can also be explicitly supplied through the view's `context`
+ property. If the view has neither `context` nor `controller` properties, the
+ `parentView`'s context will be used.
+
+ ## Layouts
+
+ Views can have a secondary template that wraps their main template. Like
+ primary templates, layouts can be any function that accepts an optional
+ context parameter and returns a string of HTML that will be inserted inside
+ view's tag. Views whose HTML element is self closing (e.g. `<input />`)
+ cannot have a layout and this property will be ignored.
+
+ Most typically in Ember a layout will be a compiled `Ember.Handlebars`
+ template.
+
+ A view's layout can be set directly with the `layout` property or reference
+ an existing Handlebars template by name with the `layoutName` property.
+
+ A template used as a layout must contain a single use of the Handlebars
+ `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
+ inserted at this location:
+
+ ```javascript
+ AViewWithLayout = Ember.View.extend({
+ layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
+ template: Ember.Handlebars.compile("I got wrapped"),
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div class="my-decorative-class">
+ I got wrapped
+ </div>
+ </div>
+ ```
+
+ See `Handlebars.helpers.yield` for more information.
+
+ ## Responding to Browser Events
+
+ Views can respond to user-initiated events in one of three ways: method
+ implementation, through an event manager, and through `{{action}}` helper use
+ in their template or layout.
+
+ ### Method Implementation
+
+ Views can respond to user-initiated events by implementing a method that
+ matches the event name. A `jQuery.Event` object will be passed as the
+ argument to this method.
+
+ ```javascript
+ AView = Ember.View.extend({
+ click: function(event){
+ // will be called when when an instance's
+ // rendered element is clicked
+ }
+ });
+ ```
+
+ ### Event Managers
+
+ Views can define an object as their `eventManager` property. This object can
+ then implement methods that match the desired event names. Matching events
+ that occur on the view's rendered HTML or the rendered HTML of any of its DOM
+ descendants will trigger this method. A `jQuery.Event` object will be passed
+ as the first argument to the method and an `Ember.View` object as the
+ second. The `Ember.View` will be the view whose rendered HTML was interacted
+ with. This may be the view with the `eventManager` property or one of its
+ descendent views.
+
+ ```javascript
+ AView = Ember.View.extend({
+ eventManager: Ember.Object.create({
+ doubleClick: function(event, view){
+ // will be called when when an instance's
+ // rendered element or any rendering
+ // of this views's descendent
+ // elements is clicked
+ }
+ })
+ });
+ ```
+
+ An event defined for an event manager takes precedence over events of the
+ same name handled through methods on the view.
+
+ ```javascript
+ AView = Ember.View.extend({
+ mouseEnter: function(event){
+ // will never trigger.
+ },
+ eventManager: Ember.Object.create({
+ mouseEnter: function(event, view){
+ // takes presedence over AView#mouseEnter
+ }
+ })
+ });
+ ```
+
+ Similarly a view's event manager will take precedence for events of any views
+ rendered as a descendent. A method name that matches an event name will not
+ be called if the view instance was rendered inside the HTML representation of
+ a view that has an `eventManager` property defined that handles events of the
+ name. Events not handled by the event manager will still trigger method calls
+ on the descendent.
+
+ ```javascript
+ OuterView = Ember.View.extend({
+ template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
+ eventManager: Ember.Object.create({
+ mouseEnter: function(event, view){
+ // view might be instance of either
+ // OutsideView or InnerView depending on
+ // where on the page the user interaction occured
+ }
+ })
+ });
+
+ InnerView = Ember.View.extend({
+ click: function(event){
+ // will be called if rendered inside
+ // an OuterView because OuterView's
+ // eventManager doesn't handle click events
+ },
+ mouseEnter: function(event){
+ // will never be called if rendered inside
+ // an OuterView.
+ }
+ });
+ ```
+
+ ### Handlebars `{{action}}` Helper
+
+ See `Handlebars.helpers.action`.
+
+ ### Event Names
+
+ Possible events names for any of the responding approaches described above
+ are:
+
+ Touch events:
+
+ * `touchStart`
+ * `touchMove`
+ * `touchEnd`
+ * `touchCancel`
+
+ Keyboard events
+
+ * `keyDown`
+ * `keyUp`
+ * `keyPress`
+
+ Mouse events
+
+ * `mouseDown`
+ * `mouseUp`
+ * `contextMenu`
+ * `click`
+ * `doubleClick`
+ * `mouseMove`
+ * `focusIn`
+ * `focusOut`
+ * `mouseEnter`
+ * `mouseLeave`
+
+ Form events:
+
+ * `submit`
+ * `change`
+ * `focusIn`
+ * `focusOut`
+ * `input`
+
+ HTML5 drag and drop events:
+
+ * `dragStart`
+ * `drag`
+ * `dragEnter`
+ * `dragLeave`
+ * `drop`
+ * `dragEnd`
+
+ ## Handlebars `{{view}}` Helper
+
+ Other `Ember.View` instances can be included as part of a view's template by
+ using the `{{view}}` Handlebars helper. See `Handlebars.helpers.view` for
+ additional information.

+ A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
+ allowing programatic management of its child views.
+
+ ## Setting Initial Child Views
+
+ The initial array of child views can be set in one of two ways. You can
+ provide a `childViews` property at creation time that contains instance of
+ `Ember.View`:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: [Ember.View.create(), Ember.View.create()]
+ });
+ ```
+
+ You can also provide a list of property names whose values are instances of
+ `Ember.View`:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', 'bView', 'cView'],
+ aView: Ember.View.create(),
+ bView: Ember.View.create(),
+ cView: Ember.View.create()
+ });
+ ```
+
+ The two strategies can be combined:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', Ember.View.create()],
+ aView: Ember.View.create()
+ });
+ ```
+
+ Each child view's rendering will be inserted into the container's rendered
+ HTML in the same order as its position in the `childViews` property.
+
+ ## Adding and Removing Child Views
+
+ The container view implements `Ember.MutableArray` allowing programatic management of its child views.
+
+ To remove a view, pass that view into a `removeObject` call on the container view.
+
+ Given an empty `<body>` the following code
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
+
+ aContainer.appendTo('body');
+ ```
+
+ Results in the HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
+
+ Removing a view
+
+ ```javascript
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView]
+ aContainer.removeObject(aContainer.get('bView'));
+ aContainer.toArray(); // [aContainer.aView]
+ ```
+
+ Will result in the following HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ </div>
+ ```
+
+ Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
+ container view.
+
+ Given an empty `<body>` the following code
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
+
+ aContainer.appendTo('body');
+ ```
+
+ Results in the HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
+
+ Adding a view
+
+ ```javascript
+ AnotherViewClass = Ember.View.extend({
+ template: Ember.Handlebars.compile("Another view")
+ });
+
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView]
+ aContainer.pushObject(AnotherViewClass.create());
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
+ ```
+
+ Will result in the following HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ <div class="ember-view">Another view</div>
+ </div>
+ ```
+
+ ## Templates and Layout
+
+ A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
+ `defaultLayout` property on a container view will not result in the template
+ or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
+ representation will only be the rendered HTML of its child views.
+
+ ## Binding a View to Display
+
+ If you would like to display a single view in your ContainerView, you can set
+ its `currentView` property. When the `currentView` property is set to a view
+ instance, it will be added to the ContainerView. If the `currentView` property
+ is later changed to a different view, the new view will replace the old view.
+ If `currentView` is set to `null`, the last `currentView` will be removed.
+
+ This functionality is useful for cases where you want to bind the display of
+ a ContainerView to a controller or state manager. For example, you can bind
+ the `currentView` of a container to a controller like this:
+
+ ```javascript
+ App.appController = Ember.Object.create({
+ view: Ember.View.create({
+ templateName: 'person_template'
+ })
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.ContainerView currentViewBinding="App.appController.view"}}
+ ```

+/**
+ `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
+ a collection (an array or array-like object) by maintaing a child view object
+ and associated DOM representation for each item in the array and ensuring
+ that child views and their associated rendered HTML are updated when items in
+ the array are added, removed, or replaced.
+
+ ## Setting content
+
+ The managed collection of objects is referenced as the `Ember.CollectionView`
+ instance's `content` property.
+
+ ```javascript
+ someItemsView = Ember.CollectionView.create({
+ content: ['A', 'B','C']
+ })
+ ```
+
+ The view for each item in the collection will have its `content` property set
+ to the item.
+
+ ## Specifying itemViewClass
+
+ By default the view class for each item in the managed collection will be an
+ instance of `Ember.View`. You can supply a different class by setting the
+ `CollectionView`'s `itemViewClass` property.
+
+ Given an empty `<body>` and the following code:
+
+ ```javascript
+ someItemsView = Ember.CollectionView.create({
+ classNames: ['a-collection'],
+ content: ['A','B','C'],
+ itemViewClass: Ember.View.extend({
+ template: Ember.Handlebars.compile("the letter: {{view.content}}")
+ })
+ });
+
+ someItemsView.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <div class="ember-view a-collection">
+ <div class="ember-view">the letter: A</div>
+ <div class="ember-view">the letter: B</div>
+ <div class="ember-view">the letter: C</div>
+ </div>
+ ```
+
+ ## Automatic matching of parent/child tagNames
+
+ Setting the `tagName` property of a `CollectionView` to any of
+ "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
+ in the item views receiving an appropriately matched `tagName` property.
+
+ Given an empty `<body>` and the following code:
+
+ ```javascript
+ anUndorderedListView = Ember.CollectionView.create({
+ tagName: 'ul',
+ content: ['A','B','C'],
+ itemViewClass: Ember.View.extend({
+ template: Ember.Handlebars.compile("the letter: {{view.content}}")
+ })
+ });
+
+ anUndorderedListView.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <ul class="ember-view a-collection">
+ <li class="ember-view">the letter: A</li>
+ <li class="ember-view">the letter: B</li>
+ <li class="ember-view">the letter: C</li>
+ </ul>
+ ```
+
+ Additional `tagName` pairs can be provided by adding to
+ `Ember.CollectionView.CONTAINER_MAP `
+
+ ```javascript
+ Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
+ ```
+
+ ## Programatic creation of child views
+
+ For cases where additional customization beyond the use of a single
+ `itemViewClass` or `tagName` matching is required CollectionView's
+ `createChildView` method can be overidden:
+
+ ```javascript
+ CustomCollectionView = Ember.CollectionView.extend({
+ createChildView: function(viewClass, attrs) {
+ if (attrs.content.kind == 'album') {
+ viewClass = App.AlbumView;
+ } else {
+ viewClass = App.SongView;
+ }
+ this._super(viewClass, attrs);
+ }
+ });
+ ```
+
+ ## Empty View
+
+ You can provide an `Ember.View` subclass to the `Ember.CollectionView`
+ instance as its `emptyView` property. If the `content` property of a
+ `CollectionView` is set to `null` or an empty array, an instance of this view
+ will be the `CollectionView`s only child.
+
+ ```javascript
+ aListWithNothing = Ember.CollectionView.create({
+ classNames: ['nothing']
+ content: null,
+ emptyView: Ember.View.extend({
+ template: Ember.Handlebars.compile("The collection is empty")
+ })
+ });
+
+ aListWithNothing.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <div class="ember-view nothing">
+ <div class="ember-view">
+ The collection is empty
+ </div>
+ </div>
+ ```
+
+ ## Adding and Removing items
+
+ The `childViews` property of a `CollectionView` should not be directly
+ manipulated. Instead, add, remove, replace items from its `content` property.
+ This will trigger appropriate changes to its rendered HTML.
+
+ ## Use in templates via the `{{collection}}` `Ember.Handlebars` helper
+
+ `Ember.Handlebars` provides a helper specifically for adding
+ `CollectionView`s to templates. See `Ember.Handlebars.collection` for more
+ details

+/**
+ Register a bound handlebars helper. Bound helpers behave similarly to regular
+ handlebars helpers, with the added ability to re-render when the underlying data
+ changes.
+
+ ## Simple example
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
+ return value.toUpperCase();
+ });
+ ```
+
+ The above bound helper can be used inside of templates as follows:
+
+ ```handlebars
+ {{capitalize name}}
+ ```
+
+ In this case, when the `name` property of the template's context changes,
+ the rendered value of the helper will update to reflect this change.
+
+ ## Example with options
+
+ Like normal handlebars helpers, bound helpers have access to the options
+ passed into the helper call.
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
+ var count = options.hash.count;
+ var a = [];
+ while(a.length < count){
+ a.push(value);
+ }
+ return a.join('');
+ });
+ ```
+
+ This helper could be used in a template as follows:
+
+ ```handlebars
+ {{repeat text count=3}}
+ ```
+
+ ## Example with bound options
+
+ Bound hash options are also supported. Example:
+
+ ```handlebars
+ {{repeat text countBinding="numRepeats"}}
+ ```
+
+ In this example, count will be bound to the value of
+ the `numRepeats` property on the context. If that property
+ changes, the helper will be re-rendered.
+
+ ## Example with extra dependencies
+
+ The `Ember.Handlebars.registerBoundHelper` method takes a variable length
+ third parameter which indicates extra dependencies on the passed in value.
+ This allows the handlebars helper to update when these dependencies change.
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
+ return value.get('name').toUpperCase();
+ }, 'name');
+ ```
+
+ ## Example with multiple bound properties
+
+ `Ember.Handlebars.registerBoundHelper` supports binding to
+ multiple properties, e.g.:
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('concatenate', function() {
+ var values = arguments[arguments.length - 1];
+ return values.join('||');
+ });
+ ```
+
+ Which allows for template syntax such as {{concatenate prop1 prop2}} or
+ {{concatenate prop1 prop2 prop3}}. If any of the properties change,
+ the helpr will re-render. Note that dependency keys cannot be
+ using in conjunction with multi-property helpers, since it is ambiguous
+ which property the dependent keys would belong to.
+
+ ## Use with unbound helper
+
+ The {{unbound}} helper can be used with bound helper invocations
+ to render them in their unbound form, e.g.
+
+ ```handlebars
+ {{unbound capitalize name}}
+ ```
+
+ In this example, if the name property changes, the helper
+ will not re-render.

+ `bindAttr` allows you to create a binding between DOM element attributes and
+ Ember objects. For example:
+
+ ```handlebars
+ <img {{bindAttr src="imageUrl" alt="imageTitle"}}>
+ ```
+
+ The above handlebars template will fill the `<img>`'s `src` attribute will
+ the value of the property referenced with `"imageUrl"` and its `alt`
+ attribute with the value of the property referenced with `"imageTitle"`.
+
+ If the rendering context of this template is the following object:
+
+ ```javascript
+ {
+ imageUrl: 'http://lolcats.info/haz-a-funny',
+ imageTitle: 'A humorous image of a cat'
+ }
+ ```
+
+ The resulting HTML output will be:
+
+ ```html
+ <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
+ ```
+
+ `bindAttr` cannot redeclare existing DOM element attributes. The use of `src`
+ in the following `bindAttr` example will be ignored and the hard coded value
+ of `src="/failwhale.gif"` will take precedence:
+
+ ```handlebars
+ <img src="/failwhale.gif" {{bindAttr src="imageUrl" alt="imageTitle"}}>
+ ```
+
+ ### `bindAttr` and the `class` attribute
+
+ `bindAttr` supports a special syntax for handling a number of cases unique
+ to the `class` DOM element attribute. The `class` attribute combines
+ multiple discreet values into a single attribute as a space-delimited
+ list of strings. Each string can be:
+
+ * a string return value of an object's property.
+ * a boolean return value of an object's property
+ * a hard-coded value
+
+ A string return value works identically to other uses of `bindAttr`. The
+ return value of the property will become the value of the attribute. For
+ example, the following view and template:
+
+ ```javascript
+ AView = Ember.View.extend({
+ someProperty: function(){
+ return "aValue";
+ }.property()
+ })
+ ```
+
+ ```handlebars
+ <img {{bindAttr class="view.someProperty}}>
+ ```
+
+ Result in the following rendered output:
+
+ ```html
+ <img class="aValue">
+ ```
+
+ A boolean return value will insert a specified class name if the property
+ returns `true` and remove the class name if the property returns `false`.
+
+ A class name is provided via the syntax
+ `somePropertyName:class-name-if-true`.
+
+ ```javascript
+ AView = Ember.View.extend({
+ someBool: true
+ })
+ ```
+
+ ```handlebars
+ <img {{bindAttr class="view.someBool:class-name-if-true"}}>
+ ```
+
+ Result in the following rendered output:
+
+ ```html
+ <img class="class-name-if-true">
+ ```
+
+ An additional section of the binding can be provided if you want to
+ replace the existing class instead of removing it when the boolean
+ value changes:
+
+ ```handlebars
+ <img {{bindAttr class="view.someBool:class-name-if-true:class-name-if-false"}}>
+ ```
+
+ A hard-coded value can be used by prepending `:` to the desired
+ class name: `:class-name-to-always-apply`.
+
+ ```handlebars
+ <img {{bindAttr class=":class-name-to-always-apply"}}>
+ ```
+
+ Results in the following rendered output:
+
+ ```html
+ <img class=":class-name-to-always-apply">
+ ```
+
+ All three strategies - string return value, boolean return value, and
+ hard-coded value – can be combined in a single declaration:
+
+ ```handlebars
+ <img {{bindAttr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>

+
+ An empty `<body>` and the following template:
+
+ ```handlebars
+ A span:
+ {{#view tagName="span"}}
+ hello.
+ {{/view}}
+ ```
+
+ Will result in HTML structure:
+
+ ```html
+ <body>
+ <!-- Note: the handlebars template script
+ also results in a rendered Ember.View
+ which is the outer <div> here -->
+
+ <div class="ember-view">
+ A span:
+ <span id="ember1" class="ember-view">
+ Hello.
+ </span>
+ </div>
+ </body>
+ ```
+
+ ### `parentView` setting
+
+ The `parentView` property of the new `Ember.View` instance created through
+ `{{view}}` will be set to the `Ember.View` instance of the template where
+ `{{view}}` was called.
+
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
+ });
+
+ aView.appendTo('body');
+ ```
+
+ Will result in HTML structure:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view">
+ my parent: ember1
+ </div>
+ </div>
+ ```
+
+ ### Setting CSS id and class attributes
+
+ The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
+ the `id` option. This option will _not_ be passed to `Ember.View.create`.
+
+ ```handlebars
+ {{#view tagName="span" id="a-custom-id"}}
+ hello.
+ {{/view}}
+ ```
+
+ Results in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <span id="a-custom-id" class="ember-view">
+ hello.
+ </span>
+ </div>
+ ```
+
+ The HTML `class` attribute can be set on the `{{view}}`'s resulting element
+ with the `class` or `classNameBindings` options. The `class` option will
+ directly set the CSS `class` attribute and will not be passed to
+ `Ember.View.create`. `classNameBindings` will be passed to `create` and use
+ `Ember.View`'s class name binding functionality:
+
+ ```handlebars
+ {{#view tagName="span" class="a-custom-class"}}
+ hello.
+ {{/view}}
+ ```
+
+ Results in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <span id="ember2" class="ember-view a-custom-class">
+ hello.
+ </span>
+ </div>
+ ```
+
+ ### Supplying a different view class
+
+ `{{view}}` can take an optional first argument before its supplied options to
+ specify a path to a custom view class.
+
+ ```handlebars
+ {{#view "MyApp.CustomView"}}
+ hello.
+ {{/view}}
+ ```
+
+ The first argument can also be a relative path. Ember will search for the
+ view class starting at the `Ember.View` of the template where `{{view}}` was
+ used as the root object:
+
+ ```javascript
+ MyApp = Ember.Application.create({});
+ MyApp.OuterView = Ember.View.extend({
+ innerViewClass: Ember.View.extend({
+ classNames: ['a-custom-view-class-as-property']
+ }),
+ template: Ember.Handlebars.compile('{{#view "innerViewClass"}} hi {{/view}}')
+ });
+
+ MyApp.OuterView.create().appendTo('body');
+ ```
+
+ Will result in the following HTML:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view a-custom-view-class-as-property">
+ hi
+ </div>
+ </div>
+ ```
+
+ ### Blockless use
+
+ If you supply a custom `Ember.View` subclass that specifies its own template
+ or provide a `templateName` option to `{{view}}` it can be used without
+ supplying a block. Attempts to use both a `templateName` option and supply a
+ block will throw an error.
+
+ ```handlebars
+ {{view "MyApp.ViewWithATemplateDefined"}}
+ ```
+
+ ### `viewName` property
+
+ You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
+ will be referenced as a property of its parent view by this name.
+
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
+ });
+
+ aView.appendTo('body');
+ aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
+ ```
+
+ @method view

+
+ // If no path is provided, treat path param as options.
+ if (path && path.data && path.data.isRenderData) {

+ path = "Ember.View";
+ }
+
+ return EmberHandlebars.ViewHelper.helper(this, path, options);
+});

+/**
+ `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
+ `Ember.CollectionView` to a template. See `Ember.CollectionView` for
+ additional information on how a `CollectionView` functions.
+
+ `{{collection}}`'s primary use is as a block helper with a `contentBinding`
+ option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
+ instance will be created for each item in its `content` property. Each view
+ will have its own `content` property set to the appropriate item in the
+ collection.
+
+ The provided block will be applied as the template for each item's view.
+
+ Given an empty `<body>` the following template:
+
+ ```handlebars
+ {{#collection contentBinding="App.items"}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
+
+ And the following application code
+
+ ```javascript
+ App = Ember.Application.create()
+ App.items = [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ]
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Hi Dave</div>
+ <div class="ember-view">Hi Mary</div>
+ <div class="ember-view">Hi Sara</div>
+ </div>
+ ```
+
+ ### Blockless Use
+
+ If you provide an `itemViewClass` option that has its own `template` you can
+ omit the block.
+
+ The following template:
+
+ ```handlebars
+ {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
+ ```
+
+ And application code
+
+ ```javascript
+ App = Ember.Application.create();
+ App.items = [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ];
+
+ App.AnItemView = Ember.View.extend({
+ template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+ });
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Greetings Dave</div>
+ <div class="ember-view">Greetings Mary</div>
+ <div class="ember-view">Greetings Sara</div>
+ </div>
+ ```
+
+ ### Specifying a CollectionView subclass
+
+ By default the `{{collection}}` helper will create an instance of
+ `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
+ the helper by passing it as the first argument:
+
+ ```handlebars
+ {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
+
+ ### Forwarded `item.*`-named Options
+
+ As with the `{{view}}`, helper options passed to the `{{collection}}` will be
+ set on the resulting `Ember.CollectionView` as properties. Additionally,
+ options prefixed with `item` will be applied to the views rendered for each
+ item (note the camelcasing):
+
+ ```handlebars
+ {{#collection contentBinding="App.items"
+ itemTagName="p"
+ itemClassNames="greeting"}}
+ Howdy {{view.content.name}}
+ {{/collection}}
+ ```
+
+ Will result in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <p class="ember-view greeting">Howdy Dave</p>
+ <p class="ember-view greeting">Howdy Mary</p>
+ <p class="ember-view greeting">Howdy Sara</p>
+ </div>
+ ```

+/**
+ The `{{#each}}` helper loops over elements in a collection, rendering its
+ block once for each item. It is an extension of the base Handlebars `{{#each}}`
+ helper:
+
+ ```javascript
+ Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
+ ```
+
+ ```handlebars
+ {{#each Developers}}
+ {{name}}
+ {{/each}}
+ ```
+
+ `{{each}}` supports an alternative syntax with element naming:
+
+ ```handlebars
+ {{#each person in Developers}}
+ {{person.name}}
+ {{/each}}
+ ```
+
+ When looping over objects that do not have properties, `{{this}}` can be used
+ to render the object:
+
+ ```javascript
+ DeveloperNames = ['Yehuda', 'Tom', 'Paul']
+ ```
+
+ ```handlebars
+ {{#each DeveloperNames}}
+ {{this}}
+ {{/each}}
+ ```
+ ### {{else}} condition
+ `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
+ if the collection is empty.
+
+ ```
+ {{#each person in Developers}}
+ {{person.name}}
+ {{else}}
+ <p>Sorry, nobody is available for this task.</p>
+ {{/each}}
+ ```
+ ### Specifying a View class for items
+ If you provide an `itemViewClass` option that references a view class
+ with its own `template` you can omit the block.
+
+ The following template:
+
+ ```handlebars
+ {{#view App.MyView }}
+ {{each view.items itemViewClass="App.AnItemView"}}
+ {{/view}}
+ ```
+
+ And application code
+
+ ```javascript
+ App = Ember.Application.create({
+ MyView: Ember.View.extend({
+ items: [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ]
+ })
+ });
+
+ App.AnItemView = Ember.View.extend({
+ template: Ember.Handlebars.compile("Greetings {{name}}")
+ });
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Greetings Dave</div>
+ <div class="ember-view">Greetings Mary</div>
+ <div class="ember-view">Greetings Sara</div>
+ </div>
+ ```
+
+ ### Representing each item with a Controller.
+ By default the controller lookup within an `{{#each}}` block will be
+ the controller of the template where the `{{#each}}` was used. If each
+ item needs to be presented by a custom controller you can provide a
+ `itemController` option which references a controller by lookup name.
+ Each item in the loop will be wrapped in an instance of this controller
+ and the item itself will be set to the `content` property of that controller.
+
+ This is useful in cases where properties of model objects need transformation
+ or synthesis for display:
+
+ ```javascript
+ App.DeveloperController = Ember.ObjectController.extend({
+ isAvailableForHire: function(){
+ return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
+ }.property('isEmployed', 'isSeekingWork')
+ })
+ ```
+
+ ```handlebars
+ {{#each person in Developers itemController="developer"}}
+ {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
+ {{/each}}
+ ```

+ The `Ember.Select` view class renders a
+ [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
+ allowing the user to choose from a list of options.
+
+ The text and `value` property of each `<option>` element within the
+ `<select>` element are populated from the objects in the `Element.Select`'s
+ `content` property. The underlying data object of the selected `<option>` is
+ stored in the `Element.Select`'s `value` property.
+
+ ### `content` as an array of Strings
+
+ The simplest version of an `Ember.Select` takes an array of strings as its
+ `content` property. The string will be used as both the `value` property and
+ the inner text of each `<option>` element inside the rendered `<select>`.
+
+ Example:
+
+ ```javascript
+ App.names = ["Yehuda", "Tom"];
+ ```
+
+ ```handlebars
+ {{view Ember.Select contentBinding="App.names"}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```
+
+ You can control which `<option>` is selected through the `Ember.Select`'s
+ `value` property directly or as a binding:
+
+ ```javascript
+ App.names = Ember.Object.create({
+ selected: 'Tom',
+ content: ["Yehuda", "Tom"]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.names.content"
+ valueBinding="App.names.selected"
+ }}
+ ```
+
+ Would result in the following HTML with the `<option>` for 'Tom' selected:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom" selected="selected">Tom</option>
+ </select>
+ ```
+
+ A user interacting with the rendered `<select>` to choose "Yehuda" would
+ update the value of `App.names.selected` to "Yehuda".
+
+ ### `content` as an Array of Objects
+
+ An `Ember.Select` can also take an array of JavaScript or Ember objects as
+ its `content` property.
+
+ When using objects you need to tell the `Ember.Select` which property should
+ be accessed on each object to supply the `value` attribute of the `<option>`
+ and which property should be used to supply the element text.
+
+ The `optionValuePath` option is used to specify the path on each object to
+ the desired property for the `value` attribute. The `optionLabelPath`
+ specifies the path on each object to the desired property for the
+ element's text. Both paths must reference each object itself as `content`:
+
+ ```javascript
+ App.programmers = [
+ Ember.Object.create({firstName: "Yehuda", id: 1}),
+ Ember.Object.create({firstName: "Tom", id: 2})
+ ];
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.programmers"
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value>Please Select</option>
+ <option value="1">Yehuda</option>
+ <option value="2">Tom</option>
+ </select>
+ ```
+
+ The `value` attribute of the selected `<option>` within an `Ember.Select`
+ can be bound to a property on another object by providing a
+ `valueBinding` option:
+
+ ```javascript
+ App.programmers = [
+ Ember.Object.create({firstName: "Yehuda", id: 1}),
+ Ember.Object.create({firstName: "Tom", id: 2})
+ ];
+
+ App.currentProgrammer = Ember.Object.create({
+ id: 2
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.programmers"
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"
+ valueBinding="App.currentProgrammer.id"}}
+ ```
+
+ Would result in the following HTML with a selected option:
+
+ ```html
+ <select class="ember-select">
+ <option value>Please Select</option>
+ <option value="1">Yehuda</option>
+ <option value="2" selected="selected">Tom</option>
+ </select>
+ ```
+
+ Interacting with the rendered element by selecting the first option
+ ('Yehuda') will update the `id` value of `App.currentProgrammer`
+ to match the `value` property of the newly selected `<option>`.
+
+ Alternatively, you can control selection through the underlying objects
+ used to render each object providing a `selectionBinding`. When the selected
+ `<option>` is changed, the property path provided to `selectionBinding`
+ will be updated to match the content object of the rendered `<option>`
+ element:
+
+ ```javascript
+ App.controller = Ember.Object.create({
+ selectedPerson: null,
+ content: [
+ Ember.Object.create({firstName: "Yehuda", id: 1}),
+ Ember.Object.create({firstName: "Tom", id: 2})
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.controller.content"
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"
+ selectionBinding="App.controller.selectedPerson"}}
+ ```
+
+ Would result in the following HTML with a selected option:
+
+ ```html
+ <select class="ember-select">
+ <option value>Please Select</option>
+ <option value="1">Yehuda</option>
+ <option value="2" selected="selected">Tom</option>
+ </select>
+ ```
+
+ Interacting with the rendered element by selecting the first option
+ ('Yehuda') will update the `selectedPerson` value of `App.controller`
+ to match the content object of the newly selected `<option>`. In this
+ case it is the first object in the `App.content.content`
+
+ ### Supplying a Prompt
+
+ A `null` value for the `Ember.Select`'s `value` or `selection` property
+ results in there being no `<option>` with a `selected` attribute:
+
+ ```javascript
+ App.controller = Ember.Object.create({
+ selected: null,
+ content: [
+ "Yehuda",
+ "Tom"
+ ]
+ });
+ ```
+
+ ``` handlebars
+ {{view Ember.Select
+ contentBinding="App.controller.content"
+ valueBinding="App.controller.selected"
+ }}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```
+
+ Although `App.controller.selected` is `null` and no `<option>`
+ has a `selected` attribute the rendered HTML will display the
+ first item as though it were selected. You can supply a string
+ value for the `Ember.Select` to display when there is no selection
+ with the `prompt` option:
+
+ ```javascript
+ App.controller = Ember.Object.create({
+ selected: null,
+ content: [
+ "Yehuda",
+ "Tom"
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.controller.content"
+ valueBinding="App.controller.selected"
+ prompt="Please select a name"
+ }}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option>Please select a name</option>
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```

+

+
+ You can also specify a particular name other than `view`:

+ {{outlet detailView}}
+ ```

+
+ ``` javascript
+ # Instantiate App.PostsView and assign to controller.masterView.

+ The `{{action}}` helper registers an HTML element within a template for DOM
+ event handling and forwards that interaction to the view's controller
+ or supplied `target` option (see 'Specifying a Target').
+
+ If the view's controller does not implement the event, the event is sent
+ to the current route, and it bubbles up the route hierarchy from there.
+
+ User interaction with that element will invoke the supplied action name on
+ the appropriate target.
+
+ Given the following Handlebars template on the page
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action anActionName}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ And application code
+
+ ```javascript
+ AController = Ember.Controller.extend({
+ anActionName: function() {}
+ });
+
+ AView = Ember.View.extend({
+ controller: AController.create(),
+ templateName: 'a-template'
+ });
+
+ aView = AView.create();
+ aView.appendTo('body');
+ ```
+
+ Will results in the following rendered HTML
+
+ ```html
+ <div class="ember-view">
+ <div data-ember-action="1">
+ click me
+ </div>
+ </div>
+ ```
+
+ Clicking "click me" will trigger the `anActionName` method of the
+ `AController`. In this case, no additional parameters will be passed.
+
+ If you provide additional parameters to the helper:
+
+ ```handlebars
+ <button {{action 'edit' post}}>Edit</button>
+ ```
+
+ Those parameters will be passed along as arguments to the JavaScript
+ function implementing the action.
+
+ ### Event Propagation
+
+ Events triggered through the action helper will automatically have
+ `.preventDefault()` called on them. You do not need to do so in your event
+ handlers.
+
+ To also disable bubbling, pass `bubbles=false` to the helper:
+
+ ```handlebars
+ <button {{action 'edit' post bubbles=false}}>Edit</button>
+ ```
+
+ If you need the default handler to trigger you should either register your
+ own event handler, or use event methods on your view class. See `Ember.View`
+ 'Responding to Browser Events' for more information.
+
+ ### Specifying DOM event type
+
+ By default the `{{action}}` helper registers for DOM `click` events. You can
+ supply an `on` option to the helper to specify a different DOM event name:
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action anActionName on="doubleClick"}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ See `Ember.View` 'Responding to Browser Events' for a list of
+ acceptable DOM event names.
+
+ NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
+ only function if an `Ember.EventDispatcher` instance is available. An
+ `Ember.EventDispatcher` instance will be created when a new `Ember.Application`
+ is created. Having an instance of `Ember.Application` will satisfy this
+ requirement.
+
+ ### Specifying a Target
+
+ There are several possible target objects for `{{action}}` helpers:
+
+ In a typical Ember application, where views are managed through use of the
+ `{{outlet}}` helper, actions will bubble to the current controller, then
+ to the current route, and then up the route hierarchy.
+
+ Alternatively, a `target` option can be provided to the helper to change
+ which object will receive the method call. This option must be a path
+ path to an object, accessible in the current context:
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action anActionName target="MyApplication.someObject"}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ Clicking "click me" in the rendered HTML of the above template will trigger
+ the `anActionName` method of the object at `MyApplication.someObject`.
+
+ If an action's target does not implement a method that matches the supplied
+ action name an error will be thrown.
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action aMethodNameThatIsMissing}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ With the following application code
+
+ ```javascript
+ AView = Ember.View.extend({
+ templateName; 'a-template',
+ // note: no method 'aMethodNameThatIsMissing'
+ anActionName: function(event) {}
+ });
+
+ aView = AView.create();
+ aView.appendTo('body');
+ ```
+
+ Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when
+ "click me" is clicked.
+
+ ### Additional Parameters
+
+ You may specify additional parameters to the `{{action}}` helper. These
+ parameters are passed along as the arguments to the JavaScript function
+ implementing the action.
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ {{#each person in people}}
+ <div {{action edit person}}>
+ click me
+ </div>
+ {{/each}}
+ </script>
+ ```
+
+ Clicking "click me" will trigger the `edit` method on the current view's
+ controller with the current person as a parameter.

### Event Delegation
- Ember.js uses a technique called _event delegation_. This allows the framework

- ### Dependency Injection
+ ### Initializers
- One thing you may have noticed while using Ember.js is that you define *classes*, not
- *instances*. When your application loads, all of the instances are created for you.
- Creating these instances is the responsibility of `Ember.Application`.
-
- When the `Ember.Application` initializes, it will look for an `Ember.Router` class
- defined on the applications's `Router` property, like this:
+ Libraries on top of Ember can register additional initializers, like so:
```javascript
- App.Router = Ember.Router.extend({
- // ...
- });
- ```
+ Ember.Application.initializer({
+ name: "store",
- If found, the router is instantiated and saved on the application's `router`
- property (note the lowercase 'r'). While you should *not* reference this router
- instance directly from your application code, having access to `App.router`
- from the console can be useful during debugging.
-
- After the router is created, the application loops through all of the
- registered _injections_ and invokes them once for each property on the
- `Ember.Application` object.
-
- An injection is a function that is responsible for instantiating objects from
- classes defined on the application. By default, the only injection registered
- instantiates controllers and makes them available on the router.
-
- For example, if you define a controller class:
-
- ```javascript
- App.MyController = Ember.Controller.extend({
- // ...
- });
- ```
-
- Your router will receive an instance of `App.MyController` saved on its
- `myController` property.
-
- Libraries on top of Ember.js can register additional injections. For example,
- if your application is using Ember Data, it registers an injection that
- instantiates `DS.Store`:
-
- ```javascript
- Ember.Application.registerInjection({
- name: 'store',
- before: 'controllers',
-
- injection: function(app, router, property) {
- if (property === 'Store') {
- set(router, 'store', app[property].create());
- }
+ initialize: function(container, application) {
+ container.register('store', 'main', application.Store);
}
});
```
### Routing
- In addition to creating your application's router, `Ember.Application` is also
- responsible for telling the router when to start routing.
-
- By default, the router will begin trying to translate the current URL into
- application state once the browser emits the `DOMContentReady` event. If you
- need to defer routing, you can call the application's `deferReadiness()` method.
- Once routing can begin, call the `advanceReadiness()` method.
-
- If there is any setup required before routing begins, you can implement a `ready()`
- method on your app that will be invoked immediately before routing begins:
+ In addition to creating your application's router, `Ember.Application` is
+ also responsible for telling the router when to start routing. Transitions
+ between routes can be logged with the LOG_TRANSITIONS flag:
```javascript
window.App = Ember.Application.create({
- ready: function() {
- this.set('router.enableLogging', true);
- }
+ LOG_TRANSITIONS: true
});
+ ```
+
+ By default, the router will begin trying to translate the current URL into
+ application state once the browser emits the `DOMContentReady` event. If you
+ need to defer routing, you can call the application's `deferReadiness()`
+ method. Once routing can begin, call the `advanceReadiness()` method.
+
+ If there is any setup required before routing begins, you can implement a
+ `ready()` method on your app that will be invoked immediately before routing
+ begins.
To begin routing, you must have at a minimum a top-level controller and view.
You define these as `App.ApplicationController` and `App.ApplicationView`,

- `connectOutlet` creates a new instance of a provided view
- class, wires it up to its associated controller, and
- assigns the new view to a property on the current controller.
-
- The purpose of this method is to enable views that use
- outlets to quickly assign new views for a given outlet.
-
- For example, an application view's template may look like
- this:
-
- ``` handlebars
- <h1>My Blog</h1>
- {{outlet}}
- ```
-
- The view for this outlet is specified by assigning a
- `view` property to the application's controller. The
- following code will assign a new `App.PostsView` to
- that outlet:
-
- ``` javascript
- applicationController.connectOutlet('posts');
- ```
-
- In general, you will also want to assign a controller
- to the newly created view. By convention, a controller
- named `postsController` will be assigned as the view's
- controller.
-
- In an application initialized using `app.initialize(router)`,
- `connectOutlet` will look for `postsController` on the
- router. The initialization process will automatically
- create an instance of `App.PostsController` called
- `postsController`, so you don't need to do anything
- beyond `connectOutlet` to assign your view and wire it
- up to its associated controller.
-
- You can supply a `content` for the controller by supplying
- a final argument after the view class:
-
- ``` javascript
- applicationController.connectOutlet('posts', App.Post.find());
- ```
-
- You can specify a particular outlet to use. For example, if your main
- template looks like:
-
- ``` handlebars
- <h1>My Blog</h1>
- {{outlet masterView}}
- {{outlet detailView}}
- ```
-
- You can assign an `App.PostsView` to the masterView outlet:
-
- ``` javascript
- applicationController.connectOutlet({
- outletName: 'masterView',
- name: 'posts',
- context: App.Post.find()
- });
- ```
-
- You can write this as:
-
- ``` javascript
- applicationController.connectOutlet('masterView', 'posts', App.Post.find());
- ```
-
-
- @method connectOutlet
- @param {String} outletName a name for the outlet to set
- @param {String} name a view/controller pair name
- @param {Object} context a context object to assign to the
- controller's `content` property, if a controller can be
- found (optional)
- */
- connectOutlet: function(name, context) {
- // Normalize arguments. Supported arguments:
- //
- // name
- // name, context

- //
- // The options hash has the following keys:

-/**
- `Ember.View` is the class in Ember responsible for encapsulating templates of HTML
- content, combining templates with data to render as sections of a page's DOM, and
- registering and responding to user-initiated events.
-
- ## HTML Tag
- The default HTML tag name used for a view's DOM representation is `div`. This can be
- customized by setting the `tagName` property. The following view class:
-
- ``` javascript
- ParagraphView = Ember.View.extend({
- tagName: 'em'
- });
- ```
-
- Would result in instances with the following HTML:
-
- ``` html
- <em id="ember1" class="ember-view"></em>
- ```
-
- ## HTML `class` Attribute
- The HTML `class` attribute of a view's tag can be set by providing a `classNames` property
- that is set to an array of strings:
-
- ``` javascript
- MyView = Ember.View.extend({
- classNames: ['my-class', 'my-other-class']
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view my-class my-other-class"></div>
- ```
-
- `class` attribute values can also be set by providing a `classNameBindings` property
- set to an array of properties names for the view. The return value of these properties
- will be added as part of the value for the view's `class` attribute. These properties
- can be computed properties:
-
- ``` javascript
- MyView = Ember.View.extend({
- classNameBindings: ['propertyA', 'propertyB'],
- propertyA: 'from-a',
- propertyB: function(){
- if(someLogic){ return 'from-b'; }
- }.property()
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view from-a from-b"></div>
- ```
-
- If the value of a class name binding returns a boolean the property name itself
- will be used as the class name if the property is true. The class name will
- not be added if the value is `false` or `undefined`.
-
- ``` javascript
- MyView = Ember.View.extend({
- classNameBindings: ['hovered'],
- hovered: true
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view hovered"></div>
- ```
-
- When using boolean class name bindings you can supply a string value other than the
- property name for use as the `class` HTML attribute by appending the preferred value after
- a ":" character when defining the binding:
-
- ``` javascript
- MyView = Ember.View.extend({
- classNameBindings: ['awesome:so-very-cool'],
- awesome: true
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view so-very-cool"></div>
- ```
-
-
- Boolean value class name bindings whose property names are in a camelCase-style
- format will be converted to a dasherized format:
-
- ``` javascript
- MyView = Ember.View.extend({
- classNameBindings: ['isUrgent'],
- isUrgent: true
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view is-urgent"></div>
- ```
-
-
- Class name bindings can also refer to object values that are found by
- traversing a path relative to the view itself:
-
- ``` javascript
- MyView = Ember.View.extend({
- classNameBindings: ['messages.empty']
- messages: Ember.Object.create({
- empty: true
- })
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view empty"></div>
- ```
-
-
- If you want to add a class name for a property which evaluates to true and
- and a different class name if it evaluates to false, you can pass a binding
- like this:
-
- ```
- // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
- Ember.View.create({
- classNameBindings: ['isEnabled:enabled:disabled']
- isEnabled: true
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view enabled"></div>
- ```
-
- When isEnabled is `false`, the resulting HTML reprensentation looks like this:
-
- ``` html
- <div id="ember1" class="ember-view disabled"></div>
- ```
-
- This syntax offers the convenience to add a class if a property is `false`:
-
- ``` javascript
- // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
- Ember.View.create({
- classNameBindings: ['isEnabled::disabled']
- isEnabled: true
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view"></div>
- ```
-
- When the `isEnabled` property on the view is set to `false`, it will result
- in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view disabled"></div>
- ```
-
- Updates to the the value of a class name binding will result in automatic update
- of the HTML `class` attribute in the view's rendered HTML representation.
- If the value becomes `false` or `undefined` the class name will be removed.
-
- Both `classNames` and `classNameBindings` are concatenated properties.
- See `Ember.Object` documentation for more information about concatenated properties.
-
- ## HTML Attributes
-
- The HTML attribute section of a view's tag can be set by providing an `attributeBindings`
- property set to an array of property names on the view. The return value of these properties
- will be used as the value of the view's HTML associated attribute:
-
- ``` javascript
- AnchorView = Ember.View.extend({
- tagName: 'a',
- attributeBindings: ['href'],
- href: 'http://google.com'
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <a id="ember1" class="ember-view" href="http://google.com"></a>
- ```
-
- If the return value of an `attributeBindings` monitored property is a boolean
- the property will follow HTML's pattern of repeating the attribute's name as
- its value:
-
- ``` javascript
- MyTextInput = Ember.View.extend({
- tagName: 'input',
- attributeBindings: ['disabled'],
- disabled: true
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <input id="ember1" class="ember-view" disabled="disabled" />
- ```
-
- `attributeBindings` can refer to computed properties:
-
- ``` javascript
- MyTextInput = Ember.View.extend({
- tagName: 'input',
- attributeBindings: ['disabled'],
- disabled: function(){
- if (someLogic) {
- return true;
- } else {
- return false;
- }
- }.property()
- });
- ```
-
- Updates to the the property of an attribute binding will result in automatic update
- of the HTML attribute in the view's rendered HTML representation.
-
- `attributeBindings` is a concatenated property. See `Ember.Object` documentation
- for more information about concatenated properties.
-
- ## Templates
- The HTML contents of a view's rendered representation are determined by its template.
- Templates can be any function that accepts an optional context parameter and returns
- a string of HTML that will be inserted within the view's tag. Most
- typically in Ember this function will be a compiled Ember.Handlebars template.
-
- ``` javascript
- AView = Ember.View.extend({
- template: Ember.Handlebars.compile('I am the template')
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view">I am the template</div>
- ```
-
- The default context of the compiled template will be the view instance itself:
-
- ``` javascript
- AView = Ember.View.extend({
- template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
- });
-
- aView = AView.create({
- content: Ember.Object.create({
- firstName: 'Barry'
- })
- excitedGreeting: function(){
- return this.get("content.firstName") + "!!!"
- }
- });
- ```
-
- Will result in an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view">Hello Barry!!!</div>
- ```
-
- Within an Ember application is more common to define a Handlebars templates as
- part of a page:
-
- ``` handlebars
- <script type='text/x-handlebars' data-template-name='some-template'>
- Hello
- </script>
- ```
-
- And associate it by name using a view's `templateName` property:
-
- ``` javascript
- AView = Ember.View.extend({
- templateName: 'some-template'
- });
- ```
-
- Using a value for `templateName` that does not have a Handlebars template with a
- matching `data-template-name` attribute will throw an error.
-
- Assigning a value to both `template` and `templateName` properties will throw an error.
-
- For views classes that may have a template later defined (e.g. as the block portion of a `{{view}}`
- Handlebars helper call in another template or in a subclass), you can provide a `defaultTemplate`
- property set to compiled template function. If a template is not later provided for the view
- instance the `defaultTemplate` value will be used:
-
- ``` javascript
- AView = Ember.View.extend({
- defaultTemplate: Ember.Handlebars.compile('I was the default'),
- template: null,
- templateName: null
- });
- ```
-
- Will result in instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view">I was the default</div>
- ```
-
- If a `template` or `templateName` is provided it will take precedence over `defaultTemplate`:
-
- ``` javascript
- AView = Ember.View.extend({
- defaultTemplate: Ember.Handlebars.compile('I was the default')
- });
-
- aView = AView.create({
- template: Ember.Handlebars.compile('I was the template, not default')
- });
- ```
-
- Will result in the following HTML representation when rendered:
-
- ``` html
- <div id="ember1" class="ember-view">I was the template, not default</div>
- ```
-
- ## Layouts
-
- Views can have a secondary template that wraps their main template. Like
- primary templates, layouts can be any function that accepts an optional context
- parameter and returns a string of HTML that will be inserted inside view's tag. Views whose HTML
- element is self closing (e.g. `<input />`) cannot have a layout and this property will be ignored.
-
- Most typically in Ember a layout will be a compiled Ember.Handlebars template.
-
- A view's layout can be set directly with the `layout` property or reference an
- existing Handlebars template by name with the `layoutName` property.
-
- A template used as a layout must contain a single use of the Handlebars `{{yield}}`
- helper. The HTML contents of a view's rendered `template` will be inserted at this location:
-
- ``` javascript
- AViewWithLayout = Ember.View.extend({
- layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
- template: Ember.Handlebars.compile("I got wrapped"),
- });
- ```
-
- Will result in view instances with an HTML representation of:
-
- ``` html
- <div id="ember1" class="ember-view">
- <div class="my-decorative-class">
- I got wrapped
- </div>
- </div>
- ```
-
- See `Handlebars.helpers.yield` for more information.
-
- ## Responding to Browser Events
-
- Views can respond to user-initiated events in one of three ways: method implementation,
- through an event manager, and through `{{action}}` helper use in their template or layout.
-
- ### Method Implementation
-
- Views can respond to user-initiated events by implementing a method that matches the
- event name. A `jQuery.Event` object will be passed as the argument to this method.
-
- ``` javascript
- AView = Ember.View.extend({
- click: function(event){
- // will be called when when an instance's
- // rendered element is clicked
- }
- });
- ```
-
- ### Event Managers
-
- Views can define an object as their `eventManager` property. This object can then
- implement methods that match the desired event names. Matching events that occur
- on the view's rendered HTML or the rendered HTML of any of its DOM descendants
- will trigger this method. A `jQuery.Event` object will be passed as the first
- argument to the method and an `Ember.View` object as the second. The `Ember.View`
- will be the view whose rendered HTML was interacted with. This may be the view with
- the `eventManager` property or one of its descendent views.
-
- ``` javascript
- AView = Ember.View.extend({
- eventManager: Ember.Object.create({
- doubleClick: function(event, view){
- // will be called when when an instance's
- // rendered element or any rendering
- // of this views's descendent
- // elements is clicked
- }
- })
- });
- ```
-
-
- An event defined for an event manager takes precedence over events of the same
- name handled through methods on the view.
-
- ``` javascript
- AView = Ember.View.extend({
- mouseEnter: function(event){
- // will never trigger.
- },
- eventManager: Ember.Object.create({
- mouseEnter: function(event, view){
- // takes presedence over AView#mouseEnter
- }
- })
- });
- ```
-
- Similarly a view's event manager will take precedence for events of any views
- rendered as a descendent. A method name that matches an event name will not be called
- if the view instance was rendered inside the HTML representation of a view that has
- an `eventManager` property defined that handles events of the name. Events not handled
- by the event manager will still trigger method calls on the descendent.
-
- ``` javascript
- OuterView = Ember.View.extend({
- template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
- eventManager: Ember.Object.create({
- mouseEnter: function(event, view){
- // view might be instance of either
- // OutsideView or InnerView depending on
- // where on the page the user interaction occured
- }
- })
- });
-
- InnerView = Ember.View.extend({
- click: function(event){
- // will be called if rendered inside
- // an OuterView because OuterView's
- // eventManager doesn't handle click events
- },
- mouseEnter: function(event){
- // will never be called if rendered inside
- // an OuterView.
- }
- });
- ```
-
- ### Handlebars `{{action}}` Helper
-
- See `Handlebars.helpers.action`.
-
- ### Event Names
-
- Possible events names for any of the responding approaches described above are:
-
- Touch events: 'touchStart', 'touchMove', 'touchEnd', 'touchCancel'
-
- Keyboard events: 'keyDown', 'keyUp', 'keyPress'
-
- Mouse events: 'mouseDown', 'mouseUp', 'contextMenu', 'click', 'doubleClick', 'mouseMove',
- 'focusIn', 'focusOut', 'mouseEnter', 'mouseLeave'
-
- Form events: 'submit', 'change', 'focusIn', 'focusOut', 'input'
-
- HTML5 drag and drop events: 'dragStart', 'drag', 'dragEnter', 'dragLeave', 'drop', 'dragEnd'
-
- ## Handlebars `{{view}}` Helper
-
- Other `Ember.View` instances can be included as part of a view's template by using the `{{view}}`
- Handlebars helper. See `Handlebars.helpers.view` for additional information.

-/**
- A `ContainerView` is an `Ember.View` subclass that allows for manual or programatic
- management of a view's `childViews` array that will correctly update the `ContainerView`
- instance's rendered DOM representation.
-
- ## Setting Initial Child Views
- The initial array of child views can be set in one of two ways. You can provide
- a `childViews` property at creation time that contains instance of `Ember.View`:
-
- ``` javascript
- aContainer = Ember.ContainerView.create({
- childViews: [Ember.View.create(), Ember.View.create()]
- });
- ```
-
- You can also provide a list of property names whose values are instances of `Ember.View`:
-
- ``` javascript
- aContainer = Ember.ContainerView.create({
- childViews: ['aView', 'bView', 'cView'],
- aView: Ember.View.create(),
- bView: Ember.View.create()
- cView: Ember.View.create()
- });
- ```
-
- The two strategies can be combined:
-
- ``` javascript
- aContainer = Ember.ContainerView.create({
- childViews: ['aView', Ember.View.create()],
- aView: Ember.View.create()
- });
- ```
-
- Each child view's rendering will be inserted into the container's rendered HTML in the same
- order as its position in the `childViews` property.
-
- ## Adding and Removing Child Views
- The views in a container's `childViews` array should be added and removed by manipulating
- the `childViews` property directly.
-
- To remove a view pass that view into a `removeObject` call on the container's `childViews` property.
-
- Given an empty `<body>` the following code
-
- ``` javascript
- aContainer = Ember.ContainerView.create({
- classNames: ['the-container'],
- childViews: ['aView', 'bView'],
- aView: Ember.View.create({
- template: Ember.Handlebars.compile("A")
- }),
- bView: Ember.View.create({
- template: Ember.Handlebars.compile("B")
- })
- });
-
- aContainer.appendTo('body');
- ```
-
- Results in the HTML
-
- ``` html
- <div class="ember-view the-container">
- <div class="ember-view">A</div>
- <div class="ember-view">B</div>
- </div>
- ```
-
- Removing a view
-
- ``` javascript
- aContainer.get('childViews'); // [aContainer.aView, aContainer.bView]
- aContainer.get('childViews').removeObject(aContainer.get('bView'));
- aContainer.get('childViews'); // [aContainer.aView]
- ```
-
- Will result in the following HTML
-
- ``` html
- <div class="ember-view the-container">
- <div class="ember-view">A</div>
- </div>
- ```
-
-
- Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
- container's `childViews` property.
-
- Given an empty `<body>` the following code
-
- ``` javascript
- aContainer = Ember.ContainerView.create({
- classNames: ['the-container'],
- childViews: ['aView', 'bView'],
- aView: Ember.View.create({
- template: Ember.Handlebars.compile("A")
- }),
- bView: Ember.View.create({
- template: Ember.Handlebars.compile("B")
- })
- });
-
- aContainer.appendTo('body');
- ```
-
- Results in the HTML
-
- ``` html
- <div class="ember-view the-container">
- <div class="ember-view">A</div>
- <div class="ember-view">B</div>
- </div>
- ```
-
- Adding a view
-
- ``` javascript
- AnotherViewClass = Ember.View.extend({
- template: Ember.Handlebars.compile("Another view")
- });
-
- aContainer.get('childViews'); // [aContainer.aView, aContainer.bView]
- aContainer.get('childViews').pushObject(AnotherViewClass.create());
- aContainer.get('childViews'); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
- ```
-
- Will result in the following HTML
-
- ``` html
- <div class="ember-view the-container">
- <div class="ember-view">A</div>
- <div class="ember-view">B</div>
- <div class="ember-view">Another view</div>
- </div>
- ```
-
-
- Direct manipulation of childViews presence or absence in the DOM via calls to
- `remove` or `removeFromParent` or calls to a container's `removeChild` may not behave
- correctly.
-
- Calling `remove()` on a child view will remove the view's HTML, but it will remain as part of its
- container's `childView`s property.
-
- Calling `removeChild()` on the container will remove the passed view instance from the container's
- `childView`s but keep its HTML within the container's rendered view.
-
- Calling `removeFromParent()` behaves as expected but should be avoided in favor of direct
- manipulation of a container's `childViews` property.
-
- ``` javascript
- aContainer = Ember.ContainerView.create({
- classNames: ['the-container'],
- childViews: ['aView', 'bView'],
- aView: Ember.View.create({
- template: Ember.Handlebars.compile("A")
- }),
- bView: Ember.View.create({
- template: Ember.Handlebars.compile("B")
- })
- });
-
- aContainer.appendTo('body');
- ```
-
- Results in the HTML
-
- ``` html
- <div class="ember-view the-container">
- <div class="ember-view">A</div>
- <div class="ember-view">B</div>
- </div>
- ```
-
- Calling `aContainer.get('aView').removeFromParent()` will result in the following HTML
-
- ``` html
- <div class="ember-view the-container">
- <div class="ember-view">B</div>
- </div>
- ```
-
- And the `Ember.View` instance stored in `aContainer.aView` will be removed from `aContainer`'s
- `childViews` array.
-
- ## Templates and Layout
-
- A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or `defaultLayout`
- property on a container view will not result in the template or layout being rendered.
- The HTML contents of a `Ember.ContainerView`'s DOM representation will only be the rendered HTML
- of its child views.
-
- ## Binding a View to Display
-
- If you would like to display a single view in your ContainerView, you can set its `currentView`
- property. When the `currentView` property is set to a view instance, it will be added to the
- ContainerView's `childViews` array. If the `currentView` property is later changed to a
- different view, the new view will replace the old view. If `currentView` is set to `null`, the
- last `currentView` will be removed.
-
- This functionality is useful for cases where you want to bind the display of a ContainerView to
- a controller or state manager. For example, you can bind the `currentView` of a container to
- a controller like this:
-
- ``` javascript
- App.appController = Ember.Object.create({
- view: Ember.View.create({
- templateName: 'person_template'
- })
- });
- ```
-
- ``` handlebars
- {{view Ember.ContainerView currentViewBinding="App.appController.view"}}
- ```
-
- ## Use lifecycle hooks
-
- This is an example of how you could implement reusable currentView view.
-
- ``` javascript
- App.ContainerView = Ember.ContainerView.extend({
- appendCurrentView: function(currentView, callback) {
- currentView.set('isVisible', true);
-
- if (!this.get('childViews').contains(currentView)) {
- this._super(currentView, callback);
- } else {
- callback();
- }
- },
- removeCurrentView: function(currentView, callback) {
- if (currentView.get('isShared')) {
- currentView.set('isVisible', false);
- callback();
- } else {
- this._super(currentView, callback);
- }
- }
- });
- ````
-
- This is an example of how you could implement animations.
-
- ```` javascript
- App.ContainerView = Ember.ContainerView.extend({
- presentCurrentView: function(currentView, callback) {
- currentView.$().animate({top: '0px'}, callback);
- },
- dismissCurrentView: function(currentView, callback) {
- currentView.$().animate({top: '-100px'}, callback);
- }
- });

-/**
- `Ember.CollectionView` is an `Ember.View` descendent responsible for managing a
- collection (an array or array-like object) by maintaing a child view object and
- associated DOM representation for each item in the array and ensuring that child
- views and their associated rendered HTML are updated when items in the array
- are added, removed, or replaced.
-
- ## Setting content
- The managed collection of objects is referenced as the `Ember.CollectionView` instance's
- `content` property.
-
- ``` javascript
- someItemsView = Ember.CollectionView.create({
- content: ['A', 'B','C']
- })
- ```
-
- The view for each item in the collection will have its `content` property set
- to the item.
-
- ## Specifying itemViewClass
- By default the view class for each item in the managed collection will be an instance
- of `Ember.View`. You can supply a different class by setting the `CollectionView`'s
- `itemViewClass` property.
-
- Given an empty `<body>` and the following code:
-
- ``` javascript
- someItemsView = Ember.CollectionView.create({
- classNames: ['a-collection'],
- content: ['A','B','C'],
- itemViewClass: Ember.View.extend({
- template: Ember.Handlebars.compile("the letter: {{view.content}}")
- })
- });
-
- someItemsView.appendTo('body');
- ```
-
- Will result in the following HTML structure
-
- ``` html
- <div class="ember-view a-collection">
- <div class="ember-view">the letter: A</div>
- <div class="ember-view">the letter: B</div>
- <div class="ember-view">the letter: C</div>
- </div>
- ```
-
- ## Automatic matching of parent/child tagNames
-
- Setting the `tagName` property of a `CollectionView` to any of
- "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
- in the item views receiving an appropriately matched `tagName` property.
-
-
- Given an empty `<body>` and the following code:
-
- ``` javascript
- anUndorderedListView = Ember.CollectionView.create({
- tagName: 'ul',
- content: ['A','B','C'],
- itemViewClass: Ember.View.extend({
- template: Ember.Handlebars.compile("the letter: {{view.content}}")
- })
- });
-
- anUndorderedListView.appendTo('body');
- ```
-
- Will result in the following HTML structure
-
- ``` html
- <ul class="ember-view a-collection">
- <li class="ember-view">the letter: A</li>
- <li class="ember-view">the letter: B</li>
- <li class="ember-view">the letter: C</li>
- </ul>
- ```
-
- Additional tagName pairs can be provided by adding to `Ember.CollectionView.CONTAINER_MAP `
-
- ``` javascript
- Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
- ```
-
-
- ## Empty View
- You can provide an `Ember.View` subclass to the `Ember.CollectionView` instance as its
- `emptyView` property. If the `content` property of a `CollectionView` is set to `null`
- or an empty array, an instance of this view will be the `CollectionView`s only child.
-
- ``` javascript
- aListWithNothing = Ember.CollectionView.create({
- classNames: ['nothing']
- content: null,
- emptyView: Ember.View.extend({
- template: Ember.Handlebars.compile("The collection is empty")
- })
- });
-
- aListWithNothing.appendTo('body');
- ```
-
- Will result in the following HTML structure
-
- ``` html
- <div class="ember-view nothing">
- <div class="ember-view">
- The collection is empty
- </div>
- </div>
- ```
-
- ## Adding and Removing items
- The `childViews` property of a `CollectionView` should not be directly manipulated. Instead,
- add, remove, replace items from its `content` property. This will trigger
- appropriate changes to its rendered HTML.
-
- ## Use in templates via the `{{collection}}` Ember.Handlebars helper
- Ember.Handlebars provides a helper specifically for adding `CollectionView`s to templates.
- See `Ember.Handlebars.collection` for more details

## The Initial State
+
When created a StateManager instance will immediately enter into the state
defined as its `start` property or the state referenced by name in its
`initialState` property:
- managerA = Ember.StateManager.create({
- start: Ember.State.create({})
- })
+ ```javascript
+ managerA = Ember.StateManager.create({
+ start: Ember.State.create({})
+ })
- managerA.get('currentState.name') // 'start'
+ managerA.get('currentState.name') // 'start'
- managerB = Ember.StateManager.create({
- initialState: 'beginHere',
- beginHere: Ember.State.create({})
- })
+ managerB = Ember.StateManager.create({
+ initialState: 'beginHere',
+ beginHere: Ember.State.create({})
+ })
- managerB.get('currentState.name') // 'beginHere'
+ managerB.get('currentState.name') // 'beginHere'
+ ```
- Because it is a property you may also provide a computed function if you wish to derive
- an `initialState` programmatically:

- A StateManager can have any number of Ember.State objects as properties
+
+ A StateManager can have any number of `Ember.State` objects as properties
and can have a single one of these states as its current state.
Calling `transitionTo` transitions between states:
- robotManager = Ember.StateManager.create({
- initialState: 'poweredDown',
- poweredDown: Ember.State.create({}),
- poweredUp: Ember.State.create({})
- })
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown',
+ poweredDown: Ember.State.create({}),
+ poweredUp: Ember.State.create({})
+ })
- robotManager.get('currentState.name') // 'poweredDown'
- robotManager.transitionTo('poweredUp')
- robotManager.get('currentState.name') // 'poweredUp'
+ robotManager.get('currentState.name') // 'poweredDown'
+ robotManager.transitionTo('poweredUp')
+ robotManager.get('currentState.name') // 'poweredUp'
+ ```
- Before transitioning into a new state the existing `currentState` will have its
- `exit` method called with the StateManager instance as its first argument and
- an object representing the transition as its second argument.

- robotManager = Ember.StateManager.create({
- initialState: 'poweredDown',
- poweredDown: Ember.State.create({
- exit: function(stateManager){
- console.log("exiting the poweredDown state")
- }
- }),

+
+ Once a StateManager is already in a state, subsequent attempts to enter that

+
+ Each state property may itself contain properties that are instances of

+ series of transitionTo method calls or via a single transitionTo with the
+ full path to the specific state. The StateManager will also keep track of the
+ full path to its currentState
+

+ robotManager.get('currentState.name') // 'charging'
+
+ robotManager.get('currentState.path') // 'poweredDown.charging'
+ ```
+
+ Enter transition methods will be called for each state and nested child state
+ in their hierarchical order. Exit methods will be called for each state and
+ its nested states in reverse hierarchical order.
+
+ Exit transitions for a parent state are not called when entering into one of
+ its child states, only when transitioning to a new section of possible states
+ in the hierarchy.

## Managing currentState with Actions
- To control which transitions between states are possible for a given state, StateManager
- can receive and route action messages to its states via the `send` method. Calling to `send` with
- an action name will begin searching for a method with the same name starting at the current state
- and moving up through the parent states in a state hierarchy until an appropriate method is found
- or the StateManager instance itself is reached.
- If an appropriately named method is found it will be called with the state manager as the first
- argument and an optional `context` object as the second argument.

-/**
- `Ember.Router` is the subclass of `Ember.StateManager` responsible for providing URL-based
- application state detection. The `Ember.Router` instance of an application detects the browser URL
- at application load time and attempts to match it to a specific application state. Additionally
- the router will update the URL to reflect an application's state changes over time.
-
- ## Adding a Router Instance to Your Application
- An instance of Ember.Router can be associated with an instance of Ember.Application in one of two ways:
-
- You can provide a subclass of Ember.Router as the `Router` property of your application. An instance
- of this Router class will be instantiated and route detection will be enabled when the application's
- `initialize` method is called. The Router instance will be available as the `router` property
- of the application:
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({ ... })
- });
-
- App.initialize();
- App.get('router') // an instance of App.Router
-
- If you want to define a Router instance elsewhere, you can pass the instance to the application's
- `initialize` method:
-
- App = Ember.Application.create();
- aRouter = Ember.Router.create({ ... });
-
- App.initialize(aRouter);
- App.get('router') // aRouter
-
- ## Adding Routes to a Router
- The `initialState` property of Ember.Router instances is named `root`. The state stored in this
- property must be a subclass of Ember.Route. The `root` route acts as the container for the
- set of routable states but is not routable itself. It should have states that are also subclasses
- of Ember.Route which each have a `route` property describing the URL pattern you would like to detect.
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- index: Ember.Route.extend({
- route: '/'
- }),
- ... additional Ember.Routes ...
- })
- })
- });
- App.initialize();
-
-
- When an application loads, Ember will parse the URL and attempt to find an Ember.Route within
- the application's states that matches. (The example URL-matching below will use the default
- 'hash syntax' provided by `Ember.HashLocation`.)
-
- In the following route structure:
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/'
- }),
- bRoute: Ember.Route.extend({
- route: '/alphabeta'
- })
- })
- })
- });
- App.initialize();
-
- Loading the page at the URL '#/' will detect the route property of 'root.aRoute' ('/') and
- transition the router first to the state named 'root' and then to the substate 'aRoute'.
-
- Respectively, loading the page at the URL '#/alphabeta' would detect the route property of
- 'root.bRoute' ('/alphabeta') and transition the router first to the state named 'root' and
- then to the substate 'bRoute'.
-
- ## Adding Nested Routes to a Router
- Routes can contain nested subroutes each with their own `route` property describing the nested
- portion of the URL they would like to detect and handle. Router, like all instances of StateManager,
- cannot call `transitonTo` with an intermediary state. To avoid transitioning the Router into an
- intermediary state when detecting URLs, a Route with nested routes must define both a base `route`
- property for itself and a child Route with a `route` property of `'/'` which will be transitioned
- to when the base route is detected in the URL:
-
- Given the following application code:
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/theBaseRouteForThisSet',
-
- indexSubRoute: Ember.Route.extend({
- route: '/'
- }),
-
- subRouteOne: Ember.Route.extend({
- route: '/subroute1'
- }),
-
- subRouteTwo: Ember.Route.extend({
- route: '/subRoute2'
- })
-
- })
- })
- })
- });
- App.initialize();
-
- When the application is loaded at '/theBaseRouteForThisSet' the Router will transition to the route
- at path 'root.aRoute' and then transition to state 'indexSubRoute'.
-
- When the application is loaded at '/theBaseRouteForThisSet/subRoute1' the Router will transition to
- the route at path 'root.aRoute' and then transition to state 'subRouteOne'.
-
- ## Route Transition Events
- Transitioning between Ember.Route instances (including the transition into the detected
- route when loading the application) triggers the same transition events as state transitions for
- base `Ember.State`s. However, the default `setup` transition event is named `connectOutlets` on
- Ember.Router instances (see 'Changing View Hierarchy in Response To State Change').
-
- The following route structure when loaded with the URL "#/"
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/',
- enter: function(router) {
- console.log("entering root.aRoute from", router.get('currentState.name'));
- },
- connectOutlets: function(router) {
- console.log("entered root.aRoute, fully transitioned to", router.get('currentState.path'));
- }
- })
- })
- })
- });
- App.initialize();
-
- Will result in console output of:
-
- 'entering root.aRoute from root'
- 'entered root.aRoute, fully transitioned to root.aRoute '
-
- Ember.Route has two additional callbacks for handling URL serialization and deserialization. See
- 'Serializing/Deserializing URLs'
-
- ## Routes With Dynamic Segments
- An Ember.Route's `route` property can reference dynamic sections of the URL by prefacing a URL segment
- with the ':' character. The values of these dynamic segments will be passed as a hash to the
- `deserialize` method of the matching Route (see 'Serializing/Deserializing URLs').
-
- ## Serializing/Deserializing URLs
- Ember.Route has two callbacks for associating a particular object context with a URL: `serialize`
- for converting an object into a parameters hash to fill dynamic segments of a URL and `deserialize`
- for converting a hash of dynamic segments from the URL into the appropriate object.
-
- ### Deserializing A URL's Dynamic Segments
- When an application is first loaded or the URL is changed manually (e.g. through the browser's
- back button) the `deserialize` method of the URL's matching Ember.Route will be called with
- the application's router as its first argument and a hash of the URL's dynamic segments and values
- as its second argument.
-
- The following route structure when loaded with the URL "#/fixed/thefirstvalue/anotherFixed/thesecondvalue":
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/fixed/:dynamicSectionA/anotherFixed/:dynamicSectionB',
- deserialize: function(router, params) {}
- })
- })
- })
- });
- App.initialize();
-
- Will call the 'deserialize' method of the Route instance at the path 'root.aRoute' with the
- following hash as its second argument:
-
- {
- dynamicSectionA: 'thefirstvalue',
- dynamicSectionB: 'thesecondvalue'
- }
-
- Within `deserialize` you should use this information to retrieve or create an appropriate context
- object for the given URL (e.g. by loading from a remote API or accessing the browser's
- `localStorage`). This object must be the `return` value of `deserialize` and will be
- passed to the Route's `connectOutlets` and `serialize` methods.
-
- When an application's state is changed from within the application itself, the context provided for
- the transition will be passed and `deserialize` is not called (see 'Transitions Between States').
-
- ### Serializing An Object For URLs with Dynamic Segments
- When transitioning into a Route whose `route` property contains dynamic segments the Route's
- `serialize` method is called with the Route's router as the first argument and the Route's
- context as the second argument. The return value of `serialize` will be used to populate the
- dynamic segments and should be an object with keys that match the names of the dynamic sections.
-
- Given the following route structure:
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/'
- }),
- bRoute: Ember.Route.extend({
- route: '/staticSection/:someDynamicSegment',
- serialize: function(router, context) {
- return {
- someDynamicSegment: context.get('name')
- }
- }
- })
- })
- })
- });
- App.initialize();
-
-
- Transitioning to "root.bRoute" with a context of `Object.create({name: 'Yehuda'})` will call
- the Route's `serialize` method with the context as its second argument and update the URL to
- '#/staticSection/Yehuda'.
-
- ## Transitions Between States
- Once a routed application has initialized its state based on the entry URL, subsequent transitions to other
- states will update the URL if the entered Route has a `route` property. Given the following route structure
- loaded at the URL '#/':
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/',
- moveElsewhere: Ember.Route.transitionTo('bRoute')
- }),
- bRoute: Ember.Route.extend({
- route: '/someOtherLocation'
- })
- })
- })
- });
- App.initialize();
-
- And application code:
-
- App.get('router').send('moveElsewhere');
-
- Will transition the application's state to 'root.bRoute' and trigger an update of the URL to
- '#/someOtherLocation'.
-
- For URL patterns with dynamic segments a context can be supplied as the second argument to `send`.
- The router will match dynamic segments names to keys on this object and fill in the URL with the
- supplied values. Given the following state structure loaded at the URL '#/':
-
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/',
- moveElsewhere: Ember.Route.transitionTo('bRoute')
- }),
- bRoute: Ember.Route.extend({
- route: '/a/route/:dynamicSection/:anotherDynamicSection',
- connectOutlets: function(router, context) {},
- })
- })
- })
- });
- App.initialize();
-
- And application code:
-
- App.get('router').send('moveElsewhere', {
- dynamicSection: '42',
- anotherDynamicSection: 'Life'
- });
-
- Will transition the application's state to 'root.bRoute' and trigger an update of the URL to
- '#/a/route/42/Life'.
-
- The context argument will also be passed as the second argument to the `serialize` method call.
-
- ## Injection of Controller Singletons
- During application initialization Ember will detect properties of the application ending in 'Controller',
- create singleton instances of each class, and assign them as properties on the router. The property name
- will be the UpperCamel name converted to lowerCamel format. These controller classes should be subclasses
- of Ember.ObjectController, Ember.ArrayController, Ember.Controller, or a custom Ember.Object that includes the
- Ember.ControllerMixin mixin.
-
- ``` javascript
- App = Ember.Application.create({
- FooController: Ember.Object.create(Ember.ControllerMixin),
- Router: Ember.Router.extend({ ... })
- });
-
- App.get('router.fooController'); // instance of App.FooController
- ```
-
- The controller singletons will have their `namespace` property set to the application and their `target`
- property set to the application's router singleton for easy integration with Ember's user event system.
- See 'Changing View Hierarchy in Response To State Change' and 'Responding to User-initiated Events.'
-
- ## Responding to User-initiated Events
- Controller instances injected into the router at application initialization have their `target` property
- set to the application's router instance. These controllers will also be the default `context` for their
- associated views. Uses of the `{{action}}` helper will automatically target the application's router.
-
- Given the following application entered at the URL '#/':
-
- ``` javascript
- App = Ember.Application.create({
- Router: Ember.Router.extend({
- root: Ember.Route.extend({
- aRoute: Ember.Route.extend({
- route: '/',
- anActionOnTheRouter: function(router, context) {
- router.transitionTo('anotherState', context);
- }
- })
- anotherState: Ember.Route.extend({
- route: '/differentUrl',
- connectOutlets: function(router, context) {
-
- }
- })
- })
- })
- });
- App.initialize();
- ```
-
- The following template:
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name="aView">
- <h1><a {{action anActionOnTheRouter}}>{{title}}</a></h1>
- </script>
- ```
-
- Will delegate `click` events on the rendered `h1` to the application's router instance. In this case the
- `anActionOnTheRouter` method of the state at 'root.aRoute' will be called with the view's controller
- as the context argument. This context will be passed to the `connectOutlets` as its second argument.
-
- Different `context` can be supplied from within the `{{action}}` helper, allowing specific context passing
- between application states:
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name="photos">
- {{#each photo in controller}}
- <h1><a {{action showPhoto photo}}>{{title}}</a></h1>
- {{/each}}
- </script>
- ```
-
- See `Handlebars.helpers.action` for additional usage examples.
-
-
- ## Changing View Hierarchy in Response To State Change
-
- Changes in application state that change the URL should be accompanied by associated changes in view
- hierarchy. This can be accomplished by calling 'connectOutlet' on the injected controller singletons from
- within the 'connectOutlets' event of an Ember.Route:
-
- ``` javascript
- App = Ember.Application.create({
- OneController: Ember.ObjectController.extend(),
- OneView: Ember.View.extend(),
-
- AnotherController: Ember.ObjectController.extend(),
- AnotherView: Ember.View.extend(),
-
- Router: Ember.Router.extend({
- root: Ember.Route.extend({

- Helper that, given a space-separated string of property paths and a context,
- returns an array of class names. Calling this method also has the side
- effect of setting up observers at those property paths, such that if they
- change, the correct class name will be reapplied to the DOM element.
-
- For example, if you pass the string "fooBar", it will first look up the
- "fooBar" value of the context. If that value is true, it will add the
- "foo-bar" class to the current element (i.e., the dasherized form of
- "fooBar"). If the value is a string, it will add that string as the class.
- Otherwise, it will not add any new class name.

-/**
- `{{view}}` inserts a new instance of `Ember.View` into a template passing its options
- to the `Ember.View`'s `create` method and using the supplied block as the view's own template.
-
- An empty `<body>` and the following template:
-
- ``` handlebars
- <script type="text/x-handlebars">
- A span:
- {{#view tagName="span"}}
- hello.
- {{/view}}
- </script>
- ```
-
- Will result in HTML structure:
-
- ``` html
- <body>
- <!-- Note: the handlebars template script
- also results in a rendered Ember.View
- which is the outer <div> here -->
-
- <div class="ember-view">
- A span:
- <span id="ember1" class="ember-view">
- Hello.
- </span>
- </div>
- </body>
- ```
-
- ### parentView setting
-
- The `parentView` property of the new `Ember.View` instance created through `{{view}}`
- will be set to the `Ember.View` instance of the template where `{{view}}` was called.
-
- ``` javascript
- aView = Ember.View.create({
- template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
- });
-
- aView.appendTo('body');
- ```
-
- Will result in HTML structure:
-
- ``` html
- <div id="ember1" class="ember-view">
- <div id="ember2" class="ember-view">
- my parent: ember1
- </div>
- </div>
- ```
-
- ### Setting CSS id and class attributes
-
- The HTML `id` attribute can be set on the `{{view}}`'s resulting element with the `id` option.
- This option will _not_ be passed to `Ember.View.create`.
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#view tagName="span" id="a-custom-id"}}
- hello.
- {{/view}}
- </script>
- ```
-
- Results in the following HTML structure:
-
- ``` html
- <div class="ember-view">
- <span id="a-custom-id" class="ember-view">
- hello.
- </span>
- </div>
- ```
-
- The HTML `class` attribute can be set on the `{{view}}`'s resulting element with
- the `class` or `classNameBindings` options. The `class` option
- will directly set the CSS `class` attribute and will not be passed to
- `Ember.View.create`. `classNameBindings` will be passed to `create` and use
- `Ember.View`'s class name binding functionality:
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#view tagName="span" class="a-custom-class"}}
- hello.
- {{/view}}
- </script>
- ```
-
- Results in the following HTML structure:
-
- ``` html
- <div class="ember-view">
- <span id="ember2" class="ember-view a-custom-class">
- hello.
- </span>
- </div>
- ```
-
- ### Supplying a different view class
-
- `{{view}}` can take an optional first argument before its supplied options to specify a
- path to a custom view class.
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#view "MyApp.CustomView"}}
- hello.
- {{/view}}
- </script>
- ```
-
- The first argument can also be a relative path. Ember will search for the view class
- starting at the `Ember.View` of the template where `{{view}}` was used as the root object:
-
- ``` javascript
- MyApp = Ember.Application.create({});
- MyApp.OuterView = Ember.View.extend({
- innerViewClass: Ember.View.extend({
- classNames: ['a-custom-view-class-as-property']
- }),
- template: Ember.Handlebars.compile('{{#view "innerViewClass"}} hi {{/view}}')
- });
-
- MyApp.OuterView.create().appendTo('body');
- ```
-
- Will result in the following HTML:
-
- ``` html
- <div id="ember1" class="ember-view">
- <div id="ember2" class="ember-view a-custom-view-class-as-property">
- hi
- </div>
- </div>
- ```
-
- ### Blockless use
-
- If you supply a custom `Ember.View` subclass that specifies its own template
- or provide a `templateName` option to `{{view}}` it can be used without supplying a block.
- Attempts to use both a `templateName` option and supply a block will throw an error.
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{view "MyApp.ViewWithATemplateDefined"}}
- </script>
- ```
-
- ### viewName property
-
- You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance will
- be referenced as a property of its parent view by this name.
-
- ``` javascript
- aView = Ember.View.create({
- template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
- });
-
- aView.appendTo('body');
- aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
- ```
-
- @method view
- @for Ember.Handlebars.helpers
- @param {String} path
- @param {Hash} options
- @return {String} HTML string

-EmberHandlebars.registerHelper('view', function(path, options) {
- Ember.assert("The view helper only takes a single argument", arguments.length <= 2);
-
- // If no path is provided, treat path param as options.
- if (path && path.data && path.data.isRenderData) {
- options = path;
- path = "Ember.View";
- }
-
- return EmberHandlebars.ViewHelper.helper(this, path, options);

-/**
- `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
- `Ember.CollectionView` to a template. See `Ember.CollectionView` for additional
- information on how a `CollectionView` functions.
-
- `{{collection}}`'s primary use is as a block helper with a `contentBinding` option
- pointing towards an `Ember.Array`-compatible object. An `Ember.View` instance will
- be created for each item in its `content` property. Each view will have its own
- `content` property set to the appropriate item in the collection.
-
- The provided block will be applied as the template for each item's view.
-
- Given an empty `<body>` the following template:
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#collection contentBinding="App.items"}}
- Hi {{view.content.name}}
- {{/collection}}
- </script>
- ```
-
- And the following application code
-
- ``` javascript
- App = Ember.Application.create()
- App.items = [
- Ember.Object.create({name: 'Dave'}),
- Ember.Object.create({name: 'Mary'}),
- Ember.Object.create({name: 'Sara'})
- ]
- ```
-
- Will result in the HTML structure below
-
- ``` html
- <div class="ember-view">
- <div class="ember-view">Hi Dave</div>
- <div class="ember-view">Hi Mary</div>
- <div class="ember-view">Hi Sara</div>
- </div>
- ```
-
- ### Blockless Use
- If you provide an `itemViewClass` option that has its own `template` you can omit
- the block.
-
- The following template:
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
- </script>
- ```
-
- And application code
-
- ``` javascript
- App = Ember.Application.create();
- App.items = [
- Ember.Object.create({name: 'Dave'}),
- Ember.Object.create({name: 'Mary'}),
- Ember.Object.create({name: 'Sara'})
- ];
-
- App.AnItemView = Ember.View.extend({
- template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
- });
- ```
-
- Will result in the HTML structure below
-
- ``` html
- <div class="ember-view">
- <div class="ember-view">Greetings Dave</div>
- <div class="ember-view">Greetings Mary</div>
- <div class="ember-view">Greetings Sara</div>
- </div>
- ```
-
- ### Specifying a CollectionView subclass
-
- By default the `{{collection}}` helper will create an instance of `Ember.CollectionView`.
- You can supply a `Ember.CollectionView` subclass to the helper by passing it
- as the first argument:
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
- Hi {{view.content.name}}
- {{/collection}}
- </script>
- ```
-
-
- ### Forwarded `item.*`-named Options
-
- As with the `{{view}}`, helper options passed to the `{{collection}}` will be set on
- the resulting `Ember.CollectionView` as properties. Additionally, options prefixed with
- `item` will be applied to the views rendered for each item (note the camelcasing):
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#collection contentBinding="App.items"
- itemTagName="p"
- itemClassNames="greeting"}}
- Howdy {{view.content.name}}
- {{/collection}}
- </script>
- ```
-
- Will result in the following HTML structure:
-
- ``` html
- <div class="ember-view">
- <p class="ember-view greeting">Howdy Dave</p>
- <p class="ember-view greeting">Howdy Mary</p>
- <p class="ember-view greeting">Howdy Sara</p>

- When looping over objects that do not have properties, `{{this}}` can be used to render the object:
-
- ``` javascript
- DeveloperNames = ['Yehuda', 'Tom', 'Paul']
- ```
-
- ``` handlebars
- {{#each DeveloperNames}}
- {{this}}
- {{/each}}
- ```
-
- ### Blockless Use
-
- If you provide an `itemViewClass` option that has its own `template` you can omit
- the block in a similar way to how it can be done with the collection helper.
-
- The following template:
-
- ``` handlebars
- <script type="text/x-handlebars">
- {{#view App.MyView }}
- {{each view.items itemViewClass="App.AnItemView"}}
- {{/view}}
- </script>
- ```
-
- And application code
-
- ``` javascript
- App = Ember.Application.create({
- MyView: Ember.View.extend({
- items: [
- Ember.Object.create({name: 'Dave'}),
- Ember.Object.create({name: 'Mary'}),
- Ember.Object.create({name: 'Sara'})
- ]
- })
- });
-
- App.AnItemView = Ember.View.extend({
- template: Ember.Handlebars.compile("Greetings {{name}}")
- });
-
- App.initialize();
- ```
-
- Will result in the HTML structure below
-
- ``` html
- <div class="ember-view">
- <div class="ember-view">Greetings Dave</div>
- <div class="ember-view">Greetings Mary</div>
- <div class="ember-view">Greetings Sara</div>
- </div>
- ```
-

-*/
-Ember.Handlebars.registerHelper('each', function(path, options) {
- if (arguments.length === 4) {
- Ember.assert("If you pass more than one argument to the each helper, it must be in the form #each foo in bar", arguments[1] === "in");
-
- var keywordName = arguments[0];

-/**
- The `{{action}}` helper registers an HTML element within a template for
- DOM event handling and forwards that interaction to the Application's router,
- the template's `Ember.View` instance, or supplied `target` option (see 'Specifying a Target').
-
- User interaction with that element will invoke the supplied action name on
- the appropriate target.
-
- Given the following Handlebars template on the page
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name='a-template'>
- <div {{action anActionName}}>
- click me
- </div>
- </script>
- ```
-
- And application code
-
- ``` javascript
- AView = Ember.View.extend({
- templateName; 'a-template',
- anActionName: function(event){}
- });
-
- aView = AView.create();
- aView.appendTo('body');
- ```
-
- Will results in the following rendered HTML
-
- ``` html
- <div class="ember-view">
- <div data-ember-action="1">
- click me
- </div>
- </div>
- ```
-
- Clicking "click me" will trigger the `anActionName` method of the `aView`
- object with a `jQuery.Event` object as its argument. The `jQuery.Event`
- object will be extended to include a `view` property that is set to the
- original view interacted with (in this case the `aView` object).
-
- ### Event Propagation
-
- Events triggered through the action helper will automatically have
- `.preventDefault()` called on them. You do not need to do so in your event
- handlers. To stop propagation of the event, simply return `false` from your
- handler.
-
- If you need the default handler to trigger you should either register your
- own event handler, or use event methods on your view class. See Ember.View
- 'Responding to Browser Events' for more information.
-
- ### Specifying DOM event type
-
- By default the `{{action}}` helper registers for DOM `click` events. You can
- supply an `on` option to the helper to specify a different DOM event name:
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name='a-template'>
- <div {{action anActionName on="doubleClick"}}>
- click me
- </div>
- </script>
- ```
-
- See Ember.View 'Responding to Browser Events' for a list of
- acceptable DOM event names.
-
- Because `{{action}}` depends on Ember's event dispatch system it will only
- function if an `Ember.EventDispatcher` instance is available. An
- `Ember.EventDispatcher` instance will be created when a new
- `Ember.Application` is created. Having an instance of `Ember.Application`
- will satisfy this requirement.
-
-
- ### Specifying a Target
- There are several possible target objects for `{{action}}` helpers:
-
- In a typical `Ember.Router`-backed Application where views are managed
- through use of the `{{outlet}}` helper, actions will be forwarded to the
- current state of the Applications's Router. See Ember.Router 'Responding
- to User-initiated Events' for more information.
-
- If you manually set the `target` property on the controller of a template's
- `Ember.View` instance, the specifed `controller.target` will become the target
- for any actions. Likely custom values for a controller's `target` are the
- controller itself or a StateManager other than the Application's Router.
-
- If the templates's view lacks a controller property the view itself is the target.
-
- Finally, a `target` option can be provided to the helper to change which object
- will receive the method call. This option must be a string representing a
- path to an object:
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name='a-template'>
- <div {{action anActionName target="MyApplication.someObject"}}>
- click me
- </div>
- </script>
- ```
-
- Clicking "click me" in the rendered HTML of the above template will trigger
- the `anActionName` method of the object at `MyApplication.someObject`.
- The first argument to this method will be a `jQuery.Event` extended to
- include a `view` property that is set to the original view interacted with.
-
- A path relative to the template's `Ember.View` instance can also be used as
- a target:
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name='a-template'>
- <div {{action anActionName target="parentView"}}>
- click me
- </div>
- </script>
- ```
-
- Clicking "click me" in the rendered HTML of the above template will trigger
- the `anActionName` method of the view's parent view.
-
- The `{{action}}` helper is `Ember.StateManager` aware. If the target of the
- action is an `Ember.StateManager` instance `{{action}}` will use the `send`
- functionality of StateManagers. The documentation for `Ember.StateManager`
- has additional information about this use.
-
- If an action's target does not implement a method that matches the supplied
- action name an error will be thrown.
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name='a-template'>
- <div {{action aMethodNameThatIsMissing}}>
- click me
- </div>
- </script>
- ```
-
- With the following application code
-
- ``` javascript
- AView = Ember.View.extend({
- templateName; 'a-template',
- // note: no method 'aMethodNameThatIsMissing'
- anActionName: function(event){}
- });
-
- aView = AView.create();
- aView.appendTo('body');
- ```
-
- Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when
- "click me" is clicked.
-
- ### Specifying a context
-
- By default the `{{action}}` helper passes the current Handlebars context
- along in the `jQuery.Event` object. You may specify an alternate object to
- pass as the context by providing a property path:
-
- ``` handlebars
- <script type="text/x-handlebars" data-template-name='a-template'>
- {{#each person in people}}
- <div {{action edit person}}>
- click me
- </div>
- {{/each}}
- </script>
- ```
-
- @method action
- @for Ember.Handlebars.helpers
- @param {String} actionName
- @param {Object...} contexts
- @param {Hash} options
-*/
-EmberHandlebars.registerHelper('action', function(actionName) {
- var options = arguments[arguments.length - 1],
- contexts = a_slice.call(arguments, 1, -1);
-
- var hash = options.hash,
- view = options.data.view,
- target, controller, link;
-
- // create a hash to pass along to registerAction
- var action = {
- eventName: hash.on || "click"
- };
-
- action.view = view = get(view, 'concreteView');
-
- if (hash.target) {
- target = getPath(this, hash.target, options);
- } else if (controller = options.data.keywords.controller) {
- target = get(controller, 'target');
- }
-
- action.target = target = target || view;
-
- if (contexts.length) {
- action.contexts = contexts = Ember.EnumerableUtils.map(contexts, function(context) {
- return getPath(this, context, options);
- }, this);
- action.context = contexts[0];
- }
-
- var output = [], url;
-
- if (hash.href && target.urlForEvent) {
- url = target.urlForEvent.apply(target, [actionName].concat(contexts));
- output.push('href="' + url + '"');
- action.link = true;
- }
-
- var actionId = ActionHelper.registerAction(actionName, action);

- ## Layout and LayoutName properties
-
- Because HTML `textarea` elements do not contain inner HTML the `layout` and `layoutName`
- properties will not be applied. See `Ember.View`'s layout section for more information.
-
- ## HTML Attributes
-
- By default `Ember.TextArea` provides support for `rows`, `cols`, `placeholder`, `disabled`,
- `maxlength` and `tabindex` attributes on a textarea. If you need to support more
- attributes have a look at the `attributeBindings` property in `Ember.View`'s HTML Attributes section.
-
- To globally add support for additional attributes you can reopen `Ember.TextArea` or `Ember.TextSupport`.
-
- ``` javascript
- Ember.TextSupport.reopen({
- attributeBindings: ["required"]
- })
- ```

-/**
- The Ember.Select view class renders a
- [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
- allowing the user to choose from a list of options.
-
- The text and `value` property of each `<option>` element within the `<select>` element
- are populated from the objects in the Element.Select's `content` property. The
- underlying data object of the selected `<option>` is stored in the
- Element.Select's `value` property.
-
- ### `content` as an array of Strings
- The simplest version of an Ember.Select takes an array of strings as its `content` property.
- The string will be used as both the `value` property and the inner text of each `<option>`
- element inside the rendered `<select>`.
-
- Example:
-
- ``` javascript
- App.names = ["Yehuda", "Tom"];
- ```
-
- ``` handlebars
- {{view Ember.Select contentBinding="App.names"}}
- ```
-
- Would result in the following HTML:
-
- ``` html
- <select class="ember-select">
- <option value="Yehuda">Yehuda</option>
- <option value="Tom">Tom</option>
- </select>
- ```
-
- You can control which `<option>` is selected through the Ember.Select's
- `value` property directly or as a binding:
-
- ``` javascript
- App.names = Ember.Object.create({
- selected: 'Tom',
- content: ["Yehuda", "Tom"]
- });
- ```
-
- ``` handlebars
- {{view Ember.Select
- contentBinding="App.names.content"
- valueBinding="App.names.selected"
- }}
- ```
-
- Would result in the following HTML with the `<option>` for 'Tom' selected:
-
- ``` html
- <select class="ember-select">
- <option value="Yehuda">Yehuda</option>
- <option value="Tom" selected="selected">Tom</option>
- </select>
- ```
-
- A user interacting with the rendered `<select>` to choose "Yehuda" would update
- the value of `App.names.selected` to "Yehuda".
-
- ### `content` as an Array of Objects
- An Ember.Select can also take an array of JavaScript or Ember objects
- as its `content` property.
-
- When using objects you need to tell the Ember.Select which property should be
- accessed on each object to supply the `value` attribute of the `<option>`
- and which property should be used to supply the element text.
-
- The `optionValuePath` option is used to specify the path on each object to
- the desired property for the `value` attribute. The `optionLabelPath`
- specifies the path on each object to the desired property for the
- element's text. Both paths must reference each object itself as 'content':
-
- ``` javascript
- App.programmers = [
- Ember.Object.create({firstName: "Yehuda", id: 1}),
- Ember.Object.create({firstName: "Tom", id: 2})
- ];
- ```
-
- ``` handlebars
- {{view Ember.Select
- contentBinding="App.programmers"
- optionValuePath="content.id"
- optionLabelPath="content.firstName"}}
- ```
-
- Would result in the following HTML:
-
- ``` html
- <select class="ember-select">
- <option value>Please Select</option>
- <option value="1">Yehuda</option>
- <option value="2">Tom</option>
- </select>
- ```
-
-
- The `value` attribute of the selected `<option>` within an Ember.Select
- can be bound to a property on another object by providing a
- `valueBinding` option:
-
- ``` javascript
- App.programmers = [
- Ember.Object.create({firstName: "Yehuda", id: 1}),
- Ember.Object.create({firstName: "Tom", id: 2})
- ];
-
- App.currentProgrammer = Ember.Object.create({
- id: 2
- });
- ```
-
- ``` handlebars
- {{view Ember.Select
- contentBinding="App.programmers"
- optionValuePath="content.id"
- optionLabelPath="content.firstName"
- valueBinding="App.currentProgrammer.id"}}
- ```
-
- Would result in the following HTML with a selected option:
-
- ``` html
- <select class="ember-select">
- <option value>Please Select</option>
- <option value="1">Yehuda</option>
- <option value="2" selected="selected">Tom</option>
- </select>
- ```
-
- Interacting with the rendered element by selecting the first option
- ('Yehuda') will update the `id` value of `App.currentProgrammer`
- to match the `value` property of the newly selected `<option>`.
-
- Alternatively, you can control selection through the underlying objects
- used to render each object providing a `selectionBinding`. When the selected
- `<option>` is changed, the property path provided to `selectionBinding`
- will be updated to match the content object of the rendered `<option>`
- element:
-
- ``` javascript
- App.controller = Ember.Object.create({
- selectedPerson: null,
- content: [
- Ember.Object.create({firstName: "Yehuda", id: 1}),
- Ember.Object.create({firstName: "Tom", id: 2})
- ]
- });
- ```
-
- ``` handlebars
- {{view Ember.Select
- contentBinding="App.controller.content"
- optionValuePath="content.id"
- optionLabelPath="content.firstName"
- selectionBinding="App.controller.selectedPerson"}}
- ```
-
- Would result in the following HTML with a selected option:
-
- ``` html
- <select class="ember-select">
- <option value>Please Select</option>
- <option value="1">Yehuda</option>
- <option value="2" selected="selected">Tom</option>
- </select>
- ```
-
-
- Interacting with the rendered element by selecting the first option
- ('Yehuda') will update the `selectedPerson` value of `App.controller`
- to match the content object of the newly selected `<option>`. In this
- case it is the first object in the `App.content.content`
-
- ### Supplying a Prompt
-
- A `null` value for the Ember.Select's `value` or `selection` property
- results in there being no `<option>` with a `selected` attribute:
-
- ``` javascript
- App.controller = Ember.Object.create({
- selected: null,
- content: [
- "Yehuda",
- "Tom"
- ]
- });
- ```
-
- ``` handlebars
- {{view Ember.Select
- contentBinding="App.controller.content"
- valueBinding="App.controller.selected"
- }}
- ```
-
- Would result in the following HTML:
-
- ``` html
- <select class="ember-select">
- <option value="Yehuda">Yehuda</option>
- <option value="Tom">Tom</option>
- </select>
- ```
-
- Although `App.controller.selected` is `null` and no `<option>`
- has a `selected` attribute the rendered HTML will display the
- first item as though it were selected. You can supply a string
- value for the Ember.Select to display when there is no selection
- with the `prompt` option:
-
- ``` javascript
- App.controller = Ember.Object.create({
- selected: null,
- content: [
- "Yehuda",
- "Tom"
- ]
- });
- ```
-
- ``` handlebars
- {{view Ember.Select
- contentBinding="App.controller.content"
- valueBinding="App.controller.selected"
- prompt="Please select a name"
- }}
- ```
-
- Would result in the following HTML:
-
- ``` html
- <select class="ember-select">
- <option>Please select a name</option>
- <option value="Yehuda">Yehuda</option>
- <option value="Tom">Tom</option>
- </select>
- ```
