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>
