Call JavaScript function in opener

Question

I need to to trigger a JavaScript function in an opener window by clicking a button in the child.

I thought the following would work, but it is not.

window.opener.MyFunction()

Answer 1

Are both windows on the same domain (e.g. foo.com?) It might be blocked due to reasons of cross-site scripting security.

Answer 2

It turns out that MyFunction() was inside a jQuery document.ready statement. It worked fine after I changed that. Interesting though, window.opener.close() still does not work.

Answer 3

Try using :

window.onload = function() { MyFunction(); }
