Close popup from next page

[Sjaakie Helderhorst]

Hi,
I wrote an ASP-page which allows friends to upload a datafile which will be
processed and stored in a database. Because large files take some time to
process I want to open a popup 'Please wait, processing' with some fancy
graphics. So, onSubmit -> check form and open popup if correct.
When data is written into the database (and summary page has finished
loading) I want to close the popup.... although I named it winDialog
(winDialog = window.open(...)) the new page tells me it can't find this
popup ( if (window.winDialog) { winDialog.close() } ). Can anyone tell me
what's wrong? Maybe I'm doing things wrong. Or could you perhaps put me in a
right direction...

Thanks!

... the new page tells me it can't find this
popup ( if (window.winDialog) { winDialog.close() } )...

<snip>

When the page in a window (or frame) is changed everything from that
window (or frame) is destroyed. Including all JavaScript functions and
local variables. So window.winDialog does not exist on the new page
unless (or until) you create it. References to external objects within a
window (or frame) cannot survive the changing of the contents of that
window (or frame).

But pop-ups are so unreliable anyway that there is probably no point in
putting any significant effort into working round that restriction.
Probably better to display a (DHTML) notification in the page with the
form and let the arrival of the replacing page remove that.

Richard.

It's a rather unorthodox way of doing things, but it works (WOOHOO!) ... and
that's what counts for me
Thanks for the quick response!

The only lines of code that matter there are

MyWindow=window.open('','MyWindow','');
MyWindow.close();

I just posted the entire test page I was using.

you have to create the object again (which will replace the old) so
that the page knows what object you are talking about.

....glad it works for ya =)
