Backbone.js collection.models()用法及代码示例

Backbone.js 集合模型指定在集合内创建的数组或模型。

用法:

collection.models

让我们举个例子。

看这个例子：

<!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>

输出：

将上述代码保存在 models.html 文件中，然后在新浏览器中打开此文件。
