当创建模型实例，它是通过定义初始化函数在创建集合时调用。
new Backbone.Collection(models, options)
<!DOCTYPE html>
<head>
<title>Collection Example</title>
<script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">
//The model 'MyTeam' contains default values and extended using the Backbone.Model class
var MyTeam = Backbone.Model.extend({
defaults: {
player: "sachin",
country: "india"
},
//The model instance is invoked by defining initialize function
initialize: function(){
document.write("Welcome to YiiBai!!!");
}
});
//The 'MyTeam1' is a collection instance and model 'MyTeam' is specified by overriding the 'model' property
var MyTeam1 = Backbone.Collection.extend({
model: MyTeam
});
var player1 = new MyTeam({
player: "sehwag",
country: "india"
});
//The 'player1' is a type of collection by passing model object in the collection
var myval=new MyTeam1([player1]);
//The 'myval.models' define the array of models inside the collection
document.write("<br>"+JSON.stringify(myval.models));
</script>
</body>
</html>
让我们进行以下步骤来看看上面的代码工作：
保存上述代码在文件initialize.html
在浏览器打开这个HTML文件。
