backbone.js集合模型

你必须重写集合类的model属性,以指定集合包含的模型类。你可以传递原始属性对象以添加,创建和重置,然后属性将被转换为适当类型的模型。

句法:

Backbone.Collection.model

让我们举个例子。

请参阅以下示例:

<!DOCTYPE html>
   <head>
      <title>Model 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' includes default values and extended using the Backbone.Model class
         var MyTeam = Backbone.Model.extend({
            defaults: {
               player: "Dhyanchand", country: "India"
            }, });
           //'MyTeam1' is an instance of the collection
         var MyTeam1 = Backbone.Collection.extend({
            model: MyTeam  //model 'MyTeam'is specified for a collection by overriding the 'model' property
         });

         //The collection 'MyTeam1' is instantiated by using new keyword
         var myval=new MyTeam1({});

         //The JSON.stringify() method returns values of collection in the JSON format
         document.write("The values in the collection are: ", JSON.stringify(myval));
      </script>
   </body>
</html>

输出:

将以上代码保存在model.html文件中,然后在新的浏览器中打开该文件。
