推荐答案

出于安全考虑，你只能得到只要iframe的内容和引用的javascript，就会从同一个域提供url。只要这是真的，这样的东西就可以工作：

For security reasons, you can only get the url for as long as the contents of the iframe, and the referencing javascript, are served from the same domain. As long as that is true, something like this will work:

document.getElementById("iframe_id").contentWindow.location.href

如果这两个域不匹配，您将遇到跨站点引用脚本安全限制。

If the two domains are mismatched, you'll run into cross site reference scripting security restrictions.
