Hi all,

I have a window with a form that is accessed directly. I would like to pop open another window from it and make the new window the parent/opener. I’ve tried the following but I keep getting ‘opener is null’ after trying to access the new parent’s Javascript methods.

[CODE]childWindow = window.open(someUrl);
window.opener = childWindow;

…

opener.someMethodInNewParent();[/CODE]

Am I going about it the correct way? Or is it not even possible to create a window and assign it as an opener to an existing window?

Thank you in advance.

@KorJan 04.2011 — You are confusing me. If you have a page A and you open a page B, as a pop-up from page A, the opener is the page A, not B, and only if seeing from inside the page B.

You can not "make a page as opener" by a simple assignment. A page [I]is or is not[/I] an opener if you open another page from it (using the [B]window.open()[/B] method), or not. To be an opener is a [I]state[/I] of being.

Can you re-form your aim, please? What, in fact, you want?

@jmendez2authorJan 05.2011 — My aim was to open a window and access its existing code.

Apologies for not wording my question correctly. I found the solution. My problem was not not being able to assign page B as the opener to page A. My problem was waiting for page B to load its content, it took a while to load. After I was able to figure out how to wait for page B to load, i was able to access page B's variables and methods. I just did not want to modify page B's code.

Thank you for the reply.

Success!
