Backbone.js collection.fetch()用法及代碼示例

Backbone.js 集合獲取方法用於使用同步方法獲取集合中的默認模型集。

用法:

collection.fetch(options)

參數說明：

options:它指定 "success" 或 "error" 回調，它們都將作為參數傳遞。

我們舉個例子來部署 fetch 方法。

看這個例子：

<!DOCTYPE html>
   <head>
      <title>Fetch 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 sync() method represents state of a model
         Backbone.sync = function(method, model) {

            //The 'method' gives 'read' state of the model by representing data in JSON format
            document.write("The fetched details are:",method + ":" + JSON.stringify(model));
         };

         //The collection instance 'details' contains the values which are to be fetched in the collection
         var details = new Backbone.Collection({
            Name:"Narendra Modi",
            Country:"India"
         });

         //This will display the model state by delegating the 'sync()' method
         details.fetch();
      </script>
   </body>
</html>

輸出：

將上述代碼保存在 fetch.html 文件中，然後在新瀏覽器中打開此文件。
