Setting variables in another window

[adeon]

Hi,

I'm trying to create specific pop'up window (for product category
selection), but in JS I'm a newbie
and some problem occured, so I have a question:

Is it possible in main window (that opens a popup) to set in popup window:
1. global variables
2. form fields

For example, I'm opening popup window like below:
categories=wind ow.open(address ,"categories"," scrollbars=no,h eight=400,width =
600");

Then I try to set global variable in popup window:
categories.glob al_variable = 1; //no effect

Or try to set form field:
categories.docu ment.some_form. some_filed.valu e = "some value"; //no effect

If none of above won't work, how could I pass some data to another window
using JS?

Yes.

You have to wait for the page in the popup window to load.

You are doing it correctly, but it only works when the page is loaded
(or at least has loaded to the point where the form and form field
exists).

So, how can I check if form field has been already loaded?

To be sure:

if (referenceToWin dow
&& !referenceToWin dow.closed
&& referenceToWind ow.document
&& referenceToWind ow.document.for ms
&& referenceToWind ow.document.for ms["foo"]
&& referenceToWind ow.document.for ms["foo"].elements
&& referenceToWind ow.document.for ms["foo"].elements["bar"]
&& typeof
referenceToWind ow.document.for ms["foo"].elements["bar"].value !=
"undefined" )
{
/*
* do something with
* referenceToWind ow.document.for ms["foo"].elements["bar"].value
*/
}

Untested, HTH.
