我一直在思考了一段时间，如果有一种方式来获得跨域AJAX（使用XML，JSON不是）工作。任何人都可以看到任何理由下是行不通的：

I've been thinking for a while if there's a way to get cross-domain AJAX (using XML, not JSON) to work. Can anyone see any reason why the following wouldn't work:

（这不会是异步的，但是可以使用的setTimeout（functionToLoadTheIframe，1）让你实现异步性？）

(this won't be asynchronous, but could using setTimeout(functionToLoadTheIframe, 1) enable you to achieve asynchronicity?)

推荐答案

是的，你可以使用iframe跨域AJAX。这让有点复杂的（更何况，如果你想使用XML），但它是可能的。这里有一个很好的文章，介绍了所使用的几种不同的黑客。我觉得一个是类似于你所描述的是什么pretty的。更重要的是，他描述了iframe来IFRAME通信这可能会帮助最多的规则。

Yes you can use iframes for cross domain AJAX. It get's a little complicated (more so if you want to use XML), but it is possible. Here's a good article that describes several different hacks that are used. I think one is pretty similar to what you're describing. More importantly he describes the rules on iframe to iframe communication which will probably help the most.
