Backbone.js collection.create()用法及代碼示例

Backbone.js 集合 create 方法用於在集合中創建模型的新實例。

用法:

collection.create(attributes,options)

參數說明：

attributes:它指定已定義模型的屬性。

options:它指定了 id、name 等參數來創建集合實例。

我們舉個例子來部署 create 方法。

看這個例子：

<!DOCTYPE html>
   <head>
      <title>Create 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 'ModelDemo' uses the sync method to display the model state such as create, read, update etc
         var ModelDemo = Backbone.Model.extend({
            sync:function (method, model, options) {
               document.write(JSON.stringify(arguments));
            }
         });

         //'CollectionDemo' is an instance of the collection
        var CollectionDemo = Backbone.Collection.extend({
           model:ModelDemo   //The model 'ModelDemo' is specified by overriding the 'model' property
        });

        //'ViewDemo' is the name of the view
        var ViewDemo = Backbone.View.extend({

        //The instance of the collection 'collectiondemo' is created within the 'initialize()' function
           initialize:function () {
              var collectiondemo = new CollectionDemo();
              collectiondemo.create({
                 Name:"Narendra Modi",
                 Country:"India"
              });
           }
        });
        new ViewDemo();  //The view instance 'ViewDemo' is created using the 'new' keyword.
      </script>
   </body>
</html>
