找到开场者iframe的父级

Question

lets say we have an iframe in page test1.html

<iframe src=test2.html"></iframe>

and there is a link in test2.html:

<a href="test3.html" target="_blank">open in new window"</a>

in test3.html how can I know the parent of the opener? (that is test1.html)

Answer 1

Something like window.opener.top should get you the window object of the parent. From there you can get .location.href , or whatever you need. Keep in mind that browser restrictions will cause this to fail if any of the documents are on different domains.
