Fork Us!Ember.Mixin Class packages/ember-metal/lib/mixin.js:336
Defined in: packages/ember-metal/lib/mixin.js:336
Module: ember-metal
The Ember.Mixin class allows you to create mixins, whose properties can be
added to other classes. For instance,
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
App.Editable = Ember.Mixin.create({
edit: function() {
console.log('starting to edit');
this.set('isEditing', true);
},
isEditing: false
});
// Mix mixins into classes by passing them as the first arguments to
// .extend.
App.CommentView = Ember.View.extend(App.Editable, {
template: Ember.Handlebars.compile('{{#if isEditing}}...{{else}}...{{/if}}')
});
commentView = App.CommentView.create();
commentView.edit(); // outputs 'starting to edit'
|
Note that Mixins are created with Ember.Mixin.create, not
Ember.Mixin.extend.
apply
(obj)
Parameters:
- obj
Returns:
- applied object
create
(arguments)
static
Creates an instance of a class. Accepts either no arguments, or an object containing values to initialize the newly instantiated object with.
1 2 3 4 5 6 7 8 9 10 11 |
App.Person = Ember.Object.extend({
helloWorld: function() {
alert("Hi, my name is " + this.get('name'));
}
});
var tom = App.Person.create({
name: 'Tom Dale'
});
tom.helloWorld(); // alerts "Hi, my name is Tom Dale".
|
create will call the init function if defined during
Ember.AnyObject.extend
If no arguments are passed to create, it will not set values to the new
instance during initialization:
1 2 |
var noName = App.Person.create(); noName.helloWorld(); // alerts undefined |
NOTE: For performance reasons, you cannot declare methods or computed
properties during create. You should instead declare methods and computed
properties when using extend.
