通过Javascript加载跨域xml [英] load cross domain xml by Javascript

问题描述

您好

是否可以从不同于纯JavaScript脚本域的域加载XML文件，而不使用php / asp / jsp / ...脚本作为代理？

类似xmlHttpRequest，但能够管理跨域请求。

Hi
Is it possible to load an XML file from a domain that differs from scripts domain with pure javascript and without using a php/asp/jsp/... script as proxy?
Something like xmlHttpRequest but with ability to manage cross domain requests.

感谢

推荐答案

您可以使用JSONP。我知道名字吮吸，因为它不真正与JSON相关。但这需要你对其他域的控制。您需要将XML包装在函数调用中，或将其分配给javascript变量：

You can use something called JSONP. I know the name sucks, because it's not really related to JSON. But this requires you have control over the other domain. You need to wrap your XML inside a function call, or assign it to a javascript variable:

func（'< xml> xml>'）;

或

var myxml ='< xml>< / xml>';

所以如果你的其他域返回这两种格式之一，请使用HTML中的< script src =http：// otherdomain / yourjsonp>< / script> 语法在JavaScript中加载数据。这是一个有点hacky，但很多人使用它。

So if your other domain returns one of these two formats, you can use the <script src="http://otherdomain/yourjsonp"></script> syntax in your html to load that data in JavaScript. It's a little hacky but a lot of people use it.
