跨域iframe通信 [英] Cross-Domain iframe communication

问题描述

我在网页上创建了iframe，并且网页的网域已明确设置为xyz.com，但iframe的网域默认为dev.xyz.com，这是我真正的网域开发。

I have an iframe being created on a page, and the page's domain is being explicitly set to 'xyz.com' but the iframe's domain is defaulting to 'dev.xyz.com', which is the actual domain i'm developing for.

问题是，当我尝试通过iframe.contentWindow.document访问该iframe时，由于域的不同而失败。

The problem is, when I try to access that iframe via iframe.contentWindow.document, it fails due to the difference in domain.

我已经尝试设置iframe的src到一个文件与document.domain ='xyz.com'，但似乎没有做的技巧...

I've tried setting the iframe's src to a file with document.domain = 'xyz.com' but that doesn't seem to be doing the trick...

任何想法？

推荐答案

iframe中的页面：

Page inside iframe:

<script>
document.domain = document.domain;
</script>

看起来很傻，但它工作。请参见 document.domain = document.domain是什么？ 。

It looks silly, but it works. See "What does document.domain = document.domain do?".
