Function Exists -- Parent Window

[crazy_nelly]

To validate that a function exists on the page, one must simply use the
syntax:
if ( window.funcName ) //...

However, the same syntax does not seem to work when attempting to validate
that a function exists on a parent window of a popup.

if ( window.opener.f uncName ) //...

Is there a syntax that works for this? I've tried everything I can think
of. TIA~ PJ

It should. Try again! :)
Seriously, you fail to say how you test it and how it fails. Does it
give false positives or false negatives?

This should work, if the code is correct. Show us the code (just a link
to a page that shows the problem would be fine), and we'll see if we can
find the bug.

Sorry, the page is not published yet and the site is not publically
accessible.

I found my issue...the function was inside the closing bracket of the
function b4 it. doh!

Thanks~

You might want to use jslint to help find things like that.
