Preventing close

[mcowen]

Hi,
I would like to ask the user whether he wants to proceed with the close because otherwise I will close all child windows. I cant stop the main window closing when I click the close box. Is there a way of stopping it? At present it closes then I get the confirm dialog and of course by this stage its too late.

Thanks
Matt

sorry. its a case of doing a proper search....heres the answer:

window.onbeforeunload = unloadAnnounce;
function unloadAnnounce(){
if (typeof(caseSummaryWindow) != "undefined&quot{
Announce = "This will close the summary page. Are you sure you want to close?"
return Announce;
}
else {
Announce = "Are you sure you want to close?"
return Announce;
}
}
