它是用来处理通过设置方法为true的编码application/json请求。

语法

示例

<!DOCTYPE html>
   <head>
      <title>Sync 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">
         //If web server that doesn't support Backbone's REST/HTTP approach, then turn on 'Backbone.emulateHTTP'
         Backbone.emulateHTTP = true;

         //If web server can't handle requests encoded as application/json, then set the 'Backbone.emulateJSON' to true
         Backbone.emulateJSON = true;

         //The sync() method reads and fetch the model data
         Backbone.sync = function(method, model) {
            document.write(method + ": " + JSON.stringify(model));
            model.set('id', 1);   //Set the model with id as '1'
         };

         //'Player' is a model name and contains the values to be displayed when you save the model
         var Player = new Backbone.Model({
            fname:"Sachin",
            lname:"Tendulkar"
         });

         //The 'save()' method saves data of the model by delegating to sync() method
         Player.save();

         //When you save the model, it updates the model along with this value
         Player.save({country: "india"});
      </script>
   </body>
</html>
