推荐答案

出于安全原因，您只能获取 url，只要 iframe 的内容和引用的 javascript 来自同一域.只要这是真的，这样的事情就会起作用:

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.
