Now the two values will be - kept in sync. - - ## One Way Bindings - - One especially useful binding customization you can use is the `oneWay()` - helper. This helper tells Ember that you are only interested in - receiving changes on the object you are binding from. For example, if you - are binding to a preference and you want to be notified if the preference - has changed, but your object will not be changing the preference itself, you - could do: - - bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") - - This way if the value of MyApp.preferencesController.bigTitles changes the - "bigTitles" property of your object will change also. However, if you - change the value of your "bigTitles" property, it will not update the - preferencesController. - - One way bindings are almost twice as fast to setup and twice as fast to - execute because the binding only has to worry about changes to one side. - - You should consider using one way bindings anytime you have an object that - may be created frequently and you do not intend to change a property; only - to monitor it for changes. (such as in the example above). - - ## Adding Bindings Manually - - All of the examples above show you how to configure a custom binding, but - the result of these customizations will be a binding template, not a fully - active Binding instance. The binding will actually become active only when you - instantiate the object the binding belongs to. It is useful however, to - understand what actually happens when the binding is activated. - - For a binding to function it must have at least a "from" property and a "to" - property. The from property path points to the object/key that you want to - bind from while the to path points to the object/key you want to bind to. - - When you define a custom binding, you are usually describing the property - you want to bind from (such as "MyApp.someController.value" in the examples - above). When your object is created, it will automatically assign the value - you want to bind "to" based on the name of your binding key. In the - examples above, during init, Ember objects will effectively call - something like this on your binding: - - binding = Ember.Binding.from(this.valueBinding).to("value"); - - This creates a new binding instance based on the template you provide, and - sets the to path to the "value" property of the new object. Now that the - binding is fully configured with a "from" and a "to", it simply needs to be - connected to become active. This is done through the connect() method: - - binding.connect(this); - - Note that when you connect a binding you pass the object you want it to be - connected to. This object will be used as the root for both the from and - to side of the binding when inspecting relative paths. This allows the - binding to be automatically inherited by subclassed objects as well. - - Now that the binding is connected, it will observe both the from and to side - and relay changes. - - If you ever needed to do so (you almost never will, but it is useful to - understand this anyway), you could manually create an active binding by - using the Ember.bind() helper method. (This is the same method used by - to setup your bindings on objects): - - Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); - - Both of these code fragments have the same effect as doing the most friendly - form of binding creation like so: - - MyApp.anotherObject = Ember.Object.create({ - valueBinding: "MyApp.someController.value", - - // OTHER CODE FOR THIS OBJECT... - - }); - - Ember's built in binding creation method makes it easy to automatically - create bindings for you. You should always use the highest-level APIs - available, even if you understand how it works underneath. - - @class Binding - @namespace Ember - @since Ember 0.9 -*/ -Ember.Binding = Binding; - - -/** - Global helper method to create a new binding.

This is one of the fundamental ways that - models, controllers and views communicate with each other in an Ember - application. - - Any object that has this mixin applied can be used in observer - operations. That includes Ember.Object and most objects you will - interact with as you write your Ember application. - - Note that you will not generally apply this mixin to classes yourself, - but you will use the features provided by this module frequently, so it - is important to understand how to use it. - - ## Using get() and set() - - Because of Ember's support for bindings and observers, you will always - access properties using the get method, and set properties using the - set method. This allows the observing objects to be notified and - computed properties to be handled properly. - - More documentation about `get` and `set` are below. - - ## Observing Property Changes - - You typically observe property changes simply by adding the `observes` - call to the end of your method declarations in classes that you write. - For example: - - Ember.Object.create({ - valueObserver: function() { - // Executes whenever the "value" property changes - }.observes('value') - }); - - Although this is the most common way to add an observer, this capability - is actually built into the Ember.Object class on top of two methods - defined in this mixin: `addObserver` and `removeObserver`. You can use - these two methods to add and remove observers yourself if you need to - do so at runtime. - - To add an observer for a property, call: - - object.addObserver('propertyKey', targetObject, targetAction) - - This will call the `targetAction` method on the `targetObject` to be called - whenever the value of the `propertyKey` changes. - - Note that if `propertyKey` is a computed property, the observer will be - called when any of the property dependencies are changed, even if the - resulting value of the computed property is unchanged. This is necessary - because computed properties are not computed until `get` is called. - - @class Observable - @namespace Ember - @extends Ember.Mixin -*/ -Ember.Observable = Ember.Mixin.create(/** @scope Ember.Observable.prototype */ { - - // compatibility - isObserverable: true, - - /** - Retrieves the value of a property from the object. - - This method is usually similar to using object[keyName] or object.keyName, - however it supports both computed properties and the unknownProperty - handler. - - Because `get` unifies the syntax for accessing all these kinds - of properties, it can make many refactorings easier, such as replacing a - simple property with a computed property, or vice versa. - - ### Computed Properties - - Computed properties are methods defined with the `property` modifier - declared at the end, such as: - - fullName: function() { - return this.getEach('firstName', 'lastName').compact().join(' '); - }.property('firstName', 'lastName') - - When you call `get` on a computed property, the function will be - called and the return value will be returned instead of the function - itself. - - ### Unknown Properties - - Likewise, if you try to call `get` on a property whose value is - undefined, the unknownProperty() method will be called on the object. - If this method returns any value other than undefined, it will be returned - instead. This allows you to implement "virtual" properties that are - not defined upfront. - - @method get - @param {String} key The property to retrieve - @return {Object} The property value or undefined. - */ - get: function(keyName) { - return get(this, keyName); - }, - - /** - To get multiple properties at once, call getProperties - with a list of strings or an array: - - record.getProperties('firstName', 'lastName', 'zipCode'); // => { firstName: 'John', lastName: 'Doe', zipCode: '10011' } - - is equivalent to: - - record.getProperties(['firstName', 'lastName', 'zipCode']); // => { firstName: 'John', lastName: 'Doe', zipCode: '10011' } - - @method getProperties - @param {String...|Array} list of keys to get - @return {Hash} - */ - getProperties: function() { - var ret = {}; - var propertyNames = arguments; - if (arguments.length === 1 && Ember.typeOf(arguments[0]) === 'array') { - propertyNames = arguments[0]; - } - for(var i = 0; i < propertyNames.length; i++) { - ret[propertyNames[i]] = get(this, propertyNames[i]); - } - return ret; - }, - - /** - Sets the provided key or path to the value. - - This method is generally very similar to calling object[key] = value or - object.key = value, except that it provides support for computed - properties, the unknownProperty() method and property observers. - - ### Computed Properties - - If you try to set a value on a key that has a computed property handler - defined (see the get() method for an example), then set() will call - that method, passing both the value and key instead of simply changing - the value itself. This is useful for those times when you need to - implement a property that is composed of one or more member - properties. - - ### Unknown Properties - - If you try to set a value on a key that is undefined in the target - object, then the unknownProperty() handler will be called instead. This - gives you an opportunity to implement complex "virtual" properties that - are not predefined on the object. If unknownProperty() returns - undefined, then set() will simply set the value on the object. - - ### Property Observers - - In addition to changing the property, set() will also register a - property change with the object. Unless you have placed this call - inside of a beginPropertyChanges() and endPropertyChanges(), any "local" - observers (i.e. observer methods declared on the same object), will be - called immediately. Any "remote" observers (i.e. observer methods - declared on another object) will be placed in a queue and called at a - later time in a coalesced manner. - - ### Chaining - - In addition to property changes, set() returns the value of the object - itself so you can do chaining like this: - - record.set('firstName', 'Charles').set('lastName', 'Jolley'); - - @method set - @param {String} key The property to set - @param {Object} value The value to set or null. - @return {Ember.Observable} - */ - set: function(keyName, value) { - set(this, keyName, value); - return this; - }, - - /** - To set multiple properties at once, call setProperties - with a Hash: - - record.setProperties({ firstName: 'Charles', lastName: 'Jolley' }); - - @method setProperties - @param {Hash} hash the hash of keys and values to set - @return {Ember.Observable} - */ - setProperties: function(hash) { - return Ember.setProperties(this, hash); - }, - - /** - Begins a grouping of property changes. - - You can use this method to group property changes so that notifications - will not be sent until the changes are finished.

You - can also iterate through a set just like an array, even accessing objects - by index, however there is no guarantee as to their order. - - All Sets are observable via the Enumerable Observer API - which works - on any enumerable object including both Sets and Arrays. - - ## Creating a Set - - You can create a set like you would most objects using - `new Ember.Set()`. Most new sets you create will be empty, but you can - also initialize the set with some content by passing an array or other - enumerable of objects to the constructor. - - Finally, you can pass in an existing set and the set will be copied. You - can also create a copy of a set by calling `Ember.Set#copy()`. - - #js - // creates a new empty set - var foundNames = new Ember.Set(); - - // creates a set with four names in it. - var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P - - // creates a copy of the names set. - var namesCopy = new Ember.Set(names); - - // same as above. - var anotherNamesCopy = names.copy(); - - ## Adding/Removing Objects - - You generally add or remove objects from a set using `add()` or - `remove()`. You can add any type of object including primitives such as - numbers, strings, and booleans. - - Unlike arrays, objects can only exist one time in a set. If you call `add()` - on a set with the same object multiple times, the object will only be added - once. Likewise, calling `remove()` with the same object multiple times will - remove the object the first time and have no effect on future calls until - you add the object to the set again. - - NOTE: You cannot add/remove null or undefined to a set. Any attempt to do so - will be ignored. - - In addition to add/remove you can also call `push()`/`pop()`. Push behaves - just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary - object, remove it and return it. This is a good way to use a set as a job - queue when you don't care which order the jobs are executed in. - - ## Testing for an Object - - To test for an object's presence in a set you simply call - `Ember.Set#contains()`. - - ## Observing changes - - When using `Ember.Set`, you can observe the `"[]"` property to be - alerted whenever the content changes. You can also add an enumerable - observer to the set to be notified of specific objects that are added and - removed from the set. See `Ember.Enumerable` for more information on - enumerables. - - This is often unhelpful. If you are filtering sets of objects, for instance, - it is very inefficient to re-filter all of the items each time the set - changes. It would be better if you could just adjust the filtered set based - on what was changed on the original set. The same issue applies to merging - sets, as well. - - ## Other Methods - - `Ember.Set` primary implements other mixin APIs. For a complete reference - on the methods you will use with `Ember.Set`, please consult these mixins. - The most useful ones will be `Ember.Enumerable` and - `Ember.MutableEnumerable` which implement most of the common iterator - methods you are used to on Array. - - Note that you can also use the `Ember.Copyable` and `Ember.Freezable` - APIs on `Ember.Set` as well. Once a set is frozen it can no longer be - modified. The benefit of this is that when you call frozenCopy() on it, - Ember will avoid making copies of the set.

It helps to instantiate, initialize and coordinate the many - objects that make up your app. - - Each Ember.js app has one and only one `Ember.Application` object. In fact, the very - first thing you should do in your application is create the instance: - - ```javascript - window.App = Ember.Application.create(); - ``` - - Typically, the application object is the only global variable. All other - classes in your app should be properties on the `Ember.Application` instance, - which highlights its first role: a global namespace. - - For example, if you define a view class, it might look like this: - - ```javascript - App.MyView = Ember.View.extend(); - ``` - - After all of your classes are defined, call `App.initialize()` to start the - application. - - Because `Ember.Application` inherits from `Ember.Namespace`, any classes - you create will have useful string representations when calling `toString()`; - see the `Ember.Namespace` documentation for more information. - - While you can think of your `Ember.Application` as a container that holds the - other classes in your application, there are several other responsibilities - going on under-the-hood that you may want to understand. - - ### Event Delegation - - Ember.js uses a technique called _event delegation_. This allows the framework - to set up a global, shared event listener instead of requiring each view to do - it manually. For example, instead of each view registering its own `mousedown` - listener on its associated element, Ember.js sets up a `mousedown` listener on - the `body`. - - If a `mousedown` event occurs, Ember.js will look at the target of the event and - start walking up the DOM node tree, finding corresponding views and invoking their - `mouseDown` method as it goes. - - `Ember.Application` has a number of default events that it listens for, as well - as a mapping from lowercase events to camel-cased view method names. For - example, the `keypress` event causes the `keyPress` method on the view to be - called, the `dblclick` event causes `doubleClick` to be called, and so on. - - If there is a browser event that Ember.js does not listen for by default, you - can specify custom events and their corresponding view method names by setting - the application's `customEvents` property: - - ```javascript - App = Ember.Application.create({ - customEvents: { - // add support for the loadedmetadata media - // player event - 'loadedmetadata': "loadedMetadata" - } - }); - ``` - - By default, the application sets up these event listeners on the document body. - However, in cases where you are embedding an Ember.js application inside an - existing page, you may want it to set up the listeners on an element inside - the body. - - For example, if only events inside a DOM element with the ID of `ember-app` should - be delegated, set your application's `rootElement` property: - - ```javascript - window.App = Ember.Application.create({ - rootElement: '#ember-app' - }); - ``` - - The `rootElement` can be either a DOM element or a jQuery-compatible selector - string. Note that *views appended to the DOM outside the root element will not - receive events.* If you specify a custom root element, make sure you only append - views inside it! - - To learn more about the advantages of event delegation and the Ember.js view layer, - and a list of the event listeners that are setup by default, visit the - [Ember.js View Layer guide](http://emberjs.com/guides/view_layer#toc_event-delegation). - - ### Dependency Injection - - 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: - - ```javascript - App.Router = Ember.Router.extend({ - // ... - }); - ``` - - 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()); - } - } - }); - ``` - - ### 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: - - ```javascript - window.App = Ember.Application.create({ - ready: function() { - this.set('router.enableLogging', true); - } - }); - - To begin routing, you must have at a minimum a top-level controller and view. - You define these as `App.ApplicationController` and `App.ApplicationView`, - respectively. Your application will not work if you do not define these two - mandatory classes. For example: - - ```javascript - App.ApplicationView = Ember.View.extend({ - templateName: 'application' - }); - App.ApplicationController = Ember.Controller.extend(); - ``` - - @class Application - @namespace Ember - @extends Ember.Namespace -*/ -Ember.Application = Ember.Namespace.extend( -/** @scope Ember.Application.prototype */{ - - /** - The root DOM element of the Application.

- ``` - - 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 -
- ``` - - 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 -
- ``` - - - 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 -
- ``` - - - 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 -
- ``` - - - 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 -
- ``` - - When isEnabled is `false`, the resulting HTML reprensentation looks like this: - - ``` html -
- ``` - - 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 -
- ``` - - When the `isEnabled` property on the view is set to `false`, it will result - in view instances with an HTML representation of: - - ``` html -
- ``` - - 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 - - ``` - - 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 - - ``` - - `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 -
I am the template
- ``` - - 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 -
Hello Barry!!!
- ``` - - Within an Ember application is more common to define a Handlebars templates as - part of a page: - - ``` handlebars - - ``` - - 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 -
I was the default
- ``` - - 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 -
I was the template, not default
- ``` - - ## 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. ``) 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("
{{yield}}
") - template: Ember.Handlebars.compile("I got wrapped"), - }); - ``` - - Will result in view instances with an HTML representation of: - - ``` html -
-
- I got wrapped -
-
- ``` - - 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.

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 `` 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 -
-
A
-
B
-
- ``` - - 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 -
-
A
-
- ``` - - - Similarly, adding a child view is accomplished by adding `Ember.View` instances to the - container's `childViews` property. - - Given an empty `` 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 -

B
-
Another view
-
- ``` - - - 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 -
-
A
-
B
-
- ``` - - Calling `aContainer.get('aView').removeFromParent()` will result in the following HTML - - ``` html -
-
B
-
- ``` - - 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); - } - }); - ```` - - @class ContainerView - @namespace Ember - @extends Ember.View -*/ - -Ember.ContainerView = Ember.View.extend({ - - init: function() { - this._super(); - - var childViews = get(this, 'childViews'); - Ember.defineProperty(this, 'childViews', childViewsProperty); - - var _childViews = this._childViews; - - forEach(childViews, function(viewName, idx) { - var view; - - if ('string' === typeof viewName) { - view = get(this, viewName); - view = this.createChildView(view); - set(this, viewName, view); - } else { - view = this.createChildView(viewName); - } - - _childViews[idx] = view; - }, this); - - // Make the _childViews array observable - Ember.A(_childViews); - - // Sets up an array observer on the child views array.

A StateManager - instance manages a number of properties that are instances of `Ember.State`, - tracks the current active state, and triggers callbacks when states have changed. - - ## Defining States - - The states of StateManager can be declared in one of two ways. First, you can define - a `states` property that contains all the states: - - managerA = Ember.StateManager.create({ - states: { - stateOne: Ember.State.create(), - stateTwo: Ember.State.create() - } - }) - - managerA.get('states') - // { - // stateOne: Ember.State.create(), - // stateTwo: Ember.State.create() - // } - - You can also add instances of `Ember.State` (or an `Ember.State` subclass) directly as properties - of a StateManager. These states will be collected into the `states` property for you. - - managerA = Ember.StateManager.create({ - stateOne: Ember.State.create(), - stateTwo: Ember.State.create() - }) - - managerA.get('states') - // { - // stateOne: Ember.State.create(), - // stateTwo: Ember.State.create() - // } - - ## 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({}) - }) - - managerA.get('currentState.name') // 'start' - - managerB = Ember.StateManager.create({ - initialState: 'beginHere', - beginHere: Ember.State.create({}) - }) - - 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: - - managerC = Ember.StateManager.create({ - initialState: function(){ - if (someLogic) { - return 'active'; - } else { - return 'passive'; - } - }.property(), - active: Ember.State.create({}), - passive: Ember.State.create({}) - }) - - ## Moving Between States - 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({}) - }) - - 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. - - After transitioning into a new state the new `currentState` will have its - `enter` 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") - } - }), - poweredUp: Ember.State.create({ - enter: function(stateManager){ - console.log("entering the poweredUp state. Destroy all humans.") - } - }) - }) - - robotManager.get('currentState.name') // 'poweredDown' - robotManager.transitionTo('poweredUp') - // will log - // 'exiting the poweredDown state' - // 'entering the poweredUp state. Destroy all humans.' - - - Once a StateManager is already in a state, subsequent attempts to enter that state will - not trigger enter or exit method calls. Attempts to transition into a state that the - manager does not have will result in no changes in the StateManager's current state: - - robotManager = Ember.StateManager.create({ - initialState: 'poweredDown', - poweredDown: Ember.State.create({ - exit: function(stateManager){ - console.log("exiting the poweredDown state") - } - }), - poweredUp: Ember.State.create({ - enter: function(stateManager){ - console.log("entering the poweredUp state. Destroy all humans.") - } - }) - }) - - robotManager.get('currentState.name') // 'poweredDown' - robotManager.transitionTo('poweredUp') - // will log - // 'exiting the poweredDown state' - // 'entering the poweredUp state. Destroy all humans.' - robotManager.transitionTo('poweredUp') // no logging, no state change - - robotManager.transitionTo('someUnknownState') // silently fails - robotManager.get('currentState.name') // 'poweredUp' - - - Each state property may itself contain properties that are instances of Ember.State. - The StateManager can transition to specific sub-states in a 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 = Ember.StateManager.create({ - initialState: 'poweredDown', - poweredDown: Ember.State.create({ - charging: Ember.State.create(), - charged: Ember.State.create() - }), - poweredUp: Ember.State.create({ - mobile: Ember.State.create(), - stationary: Ember.State.create() - }) - }) - - robotManager.get('currentState.name') // 'poweredDown' - - robotManager.transitionTo('poweredUp') - robotManager.get('currentState.name') // 'poweredUp' - - robotManager.transitionTo('mobile') - robotManager.get('currentState.name') // 'mobile' - - // transition via a state path - robotManager.transitionTo('poweredDown.charging') - 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. - - robotManager = Ember.StateManager.create({ - initialState: 'poweredDown', - poweredDown: Ember.State.create({ - enter: function(){}, - exit: function(){ - console.log("exited poweredDown state") - }, - charging: Ember.State.create({ - enter: function(){}, - exit: function(){} - }), - charged: Ember.State.create({ - enter: function(){ - console.log("entered charged state") - }, - exit: function(){ - console.log("exited charged state") - } - }) - }), - poweredUp: Ember.State.create({ - enter: function(){ - console.log("entered poweredUp state") - }, - exit: function(){}, - mobile: Ember.State.create({ - enter: function(){ - console.log("entered mobile state") - }, - exit: function(){} - }), - stationary: Ember.State.create({ - enter: function(){}, - exit: function(){} - }) - }) - }) - - - robotManager.get('currentState.path') // 'poweredDown' - robotManager.transitionTo('charged') - // logs 'entered charged state' - // but does *not* log 'exited poweredDown state' - robotManager.get('currentState.name') // 'charged - - robotManager.transitionTo('poweredUp.mobile') - // logs - // 'exited charged state' - // 'exited poweredDown state' - // 'entered poweredUp state' - // 'entered mobile state' - - During development you can set a StateManager's `enableLogging` property to `true` to - receive console messages of state transitions. - - robotManager = Ember.StateManager.create({ - enableLogging: true - }) - - ## 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. - - managerA = Ember.StateManager.create({ - initialState: 'stateOne.substateOne.subsubstateOne', - stateOne: Ember.State.create({ - substateOne: Ember.State.create({ - anAction: function(manager, context){ - console.log("an action was called") - }, - subsubstateOne: Ember.State.create({}) - }) - }) - }) - - managerA.get('currentState.name') // 'subsubstateOne' - managerA.send('anAction') - // 'stateOne.substateOne.subsubstateOne' has no anAction method - // so the 'anAction' method of 'stateOne.substateOne' is called - // and logs "an action was called" - // with managerA as the first argument - // and no second argument - - someObject = {} - managerA.send('anAction', someObject) - // the 'anAction' method of 'stateOne.substateOne' is called again - // with managerA as the first argument and - // someObject as the second argument. - - - If the StateManager attempts to send an action but does not find an appropriately named - method in the current state or while moving upwards through the state hierarchy - it will throw a new Ember.Error. Action detection only moves upwards through the state hierarchy - from the current state. It does not search in other portions of the hierarchy. - - managerB = Ember.StateManager.create({ - initialState: 'stateOne.substateOne.subsubstateOne', - stateOne: Ember.State.create({ - substateOne: Ember.State.create({ - subsubstateOne: Ember.State.create({}) - }) - }), - stateTwo: Ember.State.create({ - anAction: function(manager, context){ - // will not be called below because it is - // not a parent of the current state - } - }) - }) - - managerB.get('currentState.name') // 'subsubstateOne' - managerB.send('anAction') - // Error: could not - // respond to event anAction in state stateOne.substateOne.subsubstateOne. - - Inside of an action method the given state should delegate `transitionTo` calls on its - StateManager. - - robotManager = Ember.StateManager.create({ - initialState: 'poweredDown.charging', - poweredDown: Ember.State.create({ - charging: Ember.State.create({ - chargeComplete: function(manager, context){ - manager.transitionTo('charged') - } - }), - charged: Ember.State.create({ - boot: function(manager, context){ - manager.transitionTo('poweredUp') - } - }) - }), - poweredUp: Ember.State.create({ - beginExtermination: function(manager, context){ - manager.transitionTo('rampaging') - }, - rampaging: Ember.State.create() - }) - }) - - robotManager.get('currentState.name') // 'charging' - robotManager.send('boot') // throws error, no boot action - // in current hierarchy - robotManager.get('currentState.name') // remains 'charging' - - robotManager.send('beginExtermination') // throws error, no beginExtermination - // action in current hierarchy - robotManager.get('currentState.name') // remains 'charging' - - robotManager.send('chargeComplete') - robotManager.get('currentState.name') // 'charged' - - robotManager.send('boot') - robotManager.get('currentState.name') // 'poweredUp' - - robotManager.send('beginExtermination', allHumans) - robotManager.get('currentState.name') // 'rampaging' - - Transition actions can also be created using the `transitionTo` method of the Ember.State class.

- A span: - - Hello. - -
- - ``` - - ### 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 -

Hi Mary
-

-
- ``` - - ### Blockless Use - If you provide an `itemViewClass` option that has its own `template` you can omit - the block. - - The following template: - - ``` handlebars - - ``` - - 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 -

Additionally, options prefixed with - `item` will be applied to the views rendered for each item (note the camelcasing): - - ``` handlebars - - ``` - - Will result in the following HTML structure: - - ``` html -

-
- click me -
-
- ``` - - 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 - - ``` - - 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 - - ``` - - 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 - - ``` - - 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 - - ``` - - 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 - - ``` - - @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); - output.push('data-ember-action="' + actionId + '"'); - - return new EmberHandlebars.SafeString(output.join(" ")); -}); - -})(); - - - -(function() { -/** -@module ember -@submodule ember-handlebars -*/ - -var get = Ember.get, set = Ember.set; - -/** - - When used in a Handlebars template that is assigned to an `Ember.View` instance's - `layout` property Ember will render the layout template first, inserting the view's - own rendered output at the `{{ yield }}` location. - - An empty `` and the following application code: - - ``` javascript - AView = Ember.View.extend({ - classNames: ['a-view-with-layout'], - layout: Ember.Handlebars.compile('

Calling - `rollback()` on its transaction would cause all of the modifications to - be discarded and the record to return to the last known state before - changes were made. - - If a newly created record's transaction is rolled back, it will - immediately transition to the deleted state. - - If you do not explicitly create a transaction, a record is assigned to - an implicit transaction called the default transaction. In these cases, - you can treat your application's instance of `DS.Store` as a transaction - and call the `commit()` and `rollback()` methods on the store itself. - - Once a record has been successfully committed or rolled back, it will - be moved back to the implicit transaction. Because it will now be in - a clean state, it can be moved to a new transaction if you wish. - - ### Creating a Transaction - - To create a new transaction, call the `transaction()` method of your - application's `DS.Store` instance: - - var transaction = App.store.transaction(); - - This will return a new instance of `DS.Transaction` with no records - yet assigned to it. - - ### Adding Existing Records - - Add records to a transaction using the `add()` method: - - record = App.store.find(Person, 1); - transaction.add(record); - - Note that only records whose `isDirty` flag is `false` may be added - to a transaction.

However, new records that have a dependency on other new - records need to wait for their parent record to be saved and assigned an - ID. In that case, the child record will continue to live in the - transaction until its parent is saved, at which time the transaction will - attempt to commit again. - - For this reason, you should not re-use transactions once you have committed - them.

What we mean is that, - though each instance of a record also has a unique instance of a - `DS.StateManager`, the hierarchical states that each of *those* points - to is a shared data structure. For performance reasons, instead of each - record getting its own copy of the hierarchy of states, each state - manager points to this global, immutable shared instance. How does a - state know which record it should be acting on? We pass a reference to - the current state manager as the first parameter to every method invoked - on a state. - - The state manager passed as the first parameter is where you should stash - state about the record if needed; you should never store data on the state - object itself. If you need access to the record being acted on, you can - retrieve the state manager's `record` property. For example, if you had - an event handler `myEvent`: - - myEvent: function(manager) { - var record = manager.get('record'); - record.doSomething(); - } - - For more information about state managers in general, see the Ember.js - documentation on `Ember.StateManager`. - - ### Events, Flags, and Transitions - - A state may implement zero or more events, flags, or transitions. - - #### Events - - Events are named functions that are invoked when sent to a record. The - state manager will first look for a method with the given name on the - current state. If no method is found, it will search the current state's - parent, and then its grandparent, and so on until reaching the top of - the hierarchy. If the root is reached without an event handler being found, - an exception will be raised. This can be very helpful when debugging new - features. - - Here's an example implementation of a state with a `myEvent` event handler: - - aState: DS.State.create({ - myEvent: function(manager, param) { - console.log("Received myEvent with "+param); - } - }) - - To trigger this event: - - record.send('myEvent', 'foo'); - //=> "Received myEvent with foo" - - Note that an optional parameter can be sent to a record's `send()` method, - which will be passed as the second parameter to the event handler. - - Events should transition to a different state if appropriate. This can be - done by calling the state manager's `goToState()` method with a path to the - desired state. The state manager will attempt to resolve the state path - relative to the current state. If no state is found at that path, it will - attempt to resolve it relative to the current state's parent, and then its - parent, and so on until the root is reached. For example, imagine a hierarchy - like this: - - * created - * start <-- currentState - * inFlight - * updated - * inFlight - - If we are currently in the `start` state, calling - `goToState('inFlight')` would transition to the `created.inFlight` state, - while calling `goToState('updated.inFlight')` would transition to - the `updated.inFlight` state. - - Remember that *only events* should ever cause a state transition. You should - never call `goToState()` from outside a state's event handler. If you are - tempted to do so, create a new event and send that to the state manager. - - #### Flags - - Flags are Boolean values that can be used to introspect a record's current - state in a more user-friendly way than examining its state path. For example, - instead of doing this: - - var statePath = record.get('stateManager.currentState.path'); - if (statePath === 'created.inFlight') { - doSomething(); - } - - You can say: - - if (record.get('isNew') && record.get('isSaving')) { - doSomething(); - } - - If your state does not set a value for a given flag, the value will - be inherited from its parent (or the first place in the state hierarchy - where it is defined). - - The current set of flags are defined below. If you want to add a new flag, - in addition to the area below, you will also need to declare it in the - `DS.Model` class. - - #### Transitions - - Transitions are like event handlers but are called automatically upon - entering or exiting a state. To implement a transition, just call a method - either `enter` or `exit`: - - myState: DS.State.create({ - // Gets called automatically when entering - // this state. - enter: function(manager) { - console.log("Entered myState"); - } - }) - - Note that enter and exit events are called once per transition. If the - current state changes, but changes to another child state of the parent, - the transition event on the parent will not be triggered. -*/ - -var stateProperty = Ember.computed(function(key) { - var parent = get(this, 'parentState'); - if (parent) { - return get(parent, key); - } -}).property(); - -var isEmptyObject = function(object) { - for (var name in object) { - if (object.hasOwnProperty(name)) { return false; } - } - - return true; -}; - -var hasDefinedProperties = function(object) { - for (var name in object) { - if (object.hasOwnProperty(name) && object[name]) { return true; } - } - - return false; -}; - -DS.State = Ember.State.extend({ - isLoaded: stateProperty, - isDirty: stateProperty, - isSaving: stateProperty, - isDeleted: stateProperty, - isError: stateProperty, - isNew: stateProperty, - isValid: stateProperty, - isPending: stateProperty, - - // For states that are substates of a - // DirtyState (updated or created), it is - // useful to be able to determine which - // type of dirty state it is. - dirtyType: stateProperty -}); - -var setProperty = function(manager, context) { - var key = context.key, value = context.value; - - var record = get(manager, 'record'), - data = get(record, 'data'); - - set(data, key, value); -}; - -var setAssociation = function(manager, context) { - var key = context.key, value = context.value; - - var record = get(manager, 'record'), - data = get(record, 'data'); - - data.setAssociation(key, value); -}; - -var didChangeData = function(manager) { - var record = get(manager, 'record'), - data = get(record, 'data'); - - data._savedData = null; - record.notifyPropertyChange('data'); -}; - -// The waitingOn event shares common functionality -// between the different dirty states, but each is -// treated slightly differently.
