即使域不匹配，也可以访问iframe的父级 [英] Access parent from iframe even though domains don't match?

问题描述

我有一个正在尝试访问父项的iframe中运行的JavaScript脚本，但是我收到以下错误：

I have a javascript script that is being run from within an iframe that is trying to access the parent but I'm getting the following error:

Unsafe JavaScript attempt to access frame with URL mysite.com from frame with URL myothersite.com?. Domains, protocols and ports must match.

iframe html是在不同的域，但我不认为这将是重要的。这是生成JS错误的代码：

The iframe html is on a different domain but I didn't think that would matter. This is the code that is generating the JS error:

var parent_site = parent.document;

有没有办法？

推荐答案

如果父域是iframe域的尾部（即iframe是child.parent.com而父对象parent.com），您可以使用 document.domain =parent.com设置iframe文档的域，并避免出现此问题。

If the parent domain is a trailing part of the iframe domain (i.e., iframe is child.parent.com and parent is parent.com) you can set the domain of the iframe document with document.domain = "parent.com" and avoid the problem.

如果父级和iframe的域名无关，那么无法解决问题。

If the domains of the parent and the iframe are unrelated there is no way to work around it.
