如果使用不支持Backbone默认REST/ HTTP方式的传统网络服务器,那么你可以选择开启Backbone.emulateHTTP。 设置这个选项为true,将伪造PUT, PATCH ,DELETE和HTTP POST请求,设定使用真实的方法在X-HTTP-方法- 覆盖头部。 如果emulateJSON开启,方法将被传递作为additional _method参数。
语法
Backbone.emulateHTTP = true
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(); //Update the model with a value Player.save({country: "india"}); </script> </body> </html>
输出
让我们进行以下步骤来看看上面的代码工作:
-
保存以上的代码到emulatehttp.html文件
-
在浏览器打开这个HTML文件。
