Backbone.js集合模型指定在集合内部创建的一个或多个数组。
句法:
collection.models
让我们举个例子。
请参阅以下示例:
<!DOCTYPE html>
<head>
<title>Models 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: "Ganguly", country: "India"
}
});
//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: "Dravid", country: "India"
});
var player2 = new MyTeam({
player: "Tendulkar", country: "India"
});
//Passing the objects 'player1' and 'player2' to the collection
var myval=new MyTeam1([player1, player2]);
//The 'myval.models' define the array of models inside the collection
document.write("The values of models in the collection are: "+JSON.stringify(myval.models));
</script>
</body>
</html>
