骨干-从服务器获取原始响应 [英] Backbone - Getting raw response from server

问题描述

在Backbone中使用POST/DELETE方法时，如何获取服务器返回的原始响应(因此您无法在 fetch / parse 中获取原始响应像GET)?

How do I get the raw response returned by the server when using POST/DELETE methods in Backbone (so you can't get the raw response in fetch/parse like GET)?

推荐答案

您可以在ajax调用完成后从服务器访问 responseText .

You can access the responseText from the server when the ajax call is complete.

Backbone的 save ， fetch 等方法提供了通过调用 $.ajax 生成的jQuery Promise.

The save, fetch, etc methods from Backbone provide the jQuery promise generated by the call to $.ajax.

此承诺已解决(例如交易完成)后，您将可以访问该承诺的 responseText 属性.

When this promise has been resolved (e.g. the transaction is complete), you'll have access to the responseText property on the promise.

var promise = a_model.save();
$.when(promise).then(function(){
    console.log(promise.responseText); // if you're getting XML back it's `responseXML`
});

这是jqXHR对象上的 jQuery文档，这是您获得的promise对象

Here's the jQuery docs on the jqXHR object which is the promise object you get.

$ .when 和 .then .rel ="nofollow">延迟的对象文档

Additionally $.when and .then are described in the Deferred object documentation
