Topic awaiting preservation: Check to see if child window is still open (Page 1 of 1)

Hello. I need to know to how check if a child window is still open from a parent window that opened it. I am not having much luck finding anything online and was hopeing someone could help.


//this function open the window
var ReturnWindow = null;

function AddReturn()
{
if (ReturnWindow == null)
{
//This will open the extra item pop up
ReturnWindow = window.open'AddReturn.asp?','ReturnItems','width=670,height=500');
ReturnWindow.focus;
}
}


//This is supposed to check if the window is still open
function WindowClose()
{
if (ReturnWindow != null)
{
alert("Please close or submit all the extra forms.");
ReturnWindow.focus;
}
}

I get the alert box if the window is open but I also get the alert box if the window was opened and closed. Thanks for any help.

Thank you and have a great day.

Try setting the variable ReturnWindow to null when the opened window closes.
I'm not sure about this, but I think you could do something like:
onUnLoad="opener.ReturnWindow = null;"
I could be sooo wrong.

Or you could just check this page: http://www.xs4all.nl/~ppk/js/croswin.html

if(newWin && !newWin.closed)
alert('newWin is not null, so the child window was opened once, and newWin.closed is false, so it is still open');
