Hi Mark,
I found your site when trying to solve a window.onbeforeunload event. My
problem is as below:
If I don't want to use the dialogbox provided by the window.onbeforeunload
event, I call my own window.openDialog(); when it return a value where user
click cancel, how do I cancel watever operation that user choose? (back,
next page, stop, or refresh)?
I try to use window.getBrowser().stop() in firefox, the event will stop, but
the mouse cursor remain busy. I try to use
var httpChannel =
aRequest.QueryInterface(Components.interfaces.nsIHttpChannel);
httpChannel.cancel(2152398850);
But this function won't work for "back" button.
Thanks so much in advance.
Best Regards,
Lim Wen Peng

Supposedly window.stop() should stop the page loading. Some browsers simply
will not allow you to cancel unloading of a page. To be honest, why should
they? The user tried to close the page, and that is their choice, not yours,
since it is their browser.
However, onbeforeunload is a non-standard event, and cannot be used on many
browsers, making it essentially useless for any of my purposes (since I only
use scripts that work properly cross-browser, or are in a proper standard).
I have not investigated how it works.

Hi Mark,
Really thanks for your reply. I will try to keep looking for a better
way of doing that. :)
