[Webdev] JavaScript variable scope

Fri Jun 23 18:43:16 IST 2000

I figured what I was doing wrong.

In foo() I was referencing the global data as e.g
browserversion.

But what I should have done was

window.parent.frames["leftframe"].browserversion.

This way works when you call foo from either frame and not just the one its
defined in.

Thanks for your help.
