getting problem in window.onbeforeunload

[sbettadpur]

hello

My requirement goes like this

If I logged into my application for that time session variable will be created, and login entry will be entering into database table. If i press logout button logout entry will be entered into same table.

in between if i press window close button the logout entry will not be entered into database table.

I need once i closed window it should ask "do you want to close" like that and entry should be made in logintimestamp table.

for this i got code from google called window.onbefore unload

but using this event handler how to catch "true" and "false" values.

If the user cancels, you don't need to do anything. However, if (s)he does decide to leave the page, you can open a small window to run your logout code.
