javascript to detect browser closing

[c ccc]

hi,

i need to have a way to detect the browser closing event, so I can invoke my servlet to update the database ( time the user spent for the application). i tried to use onunload to trigger the servlet, but, it actually triggers for the back button clicking, reload, and any link clickings as well. Is there a way, javascript can detect the close button clicking only?

thanks a lot.

c ccc,

welcome to the Javaranch. You may not have noticed our naming policy on the way in. it requires a real sounding first and last name, although a first name initial is ok. please go here and update your screen name.

edit - i just noticed you have been asked before to change your name.

Second, i'm not sure this is the best forum for this question. I'm going to see about getting it moved to a more appropriate venue, where hopefully you can get the help you need.

Let's move this beaut to s ssservlets.

Actually, it'd be more appropriate in the HTML forum, where this very subject has been broached many a time.

Moving forward (or is it a redirect? ) ...

There is no real way to detect it.

Rely on your session end event on the server.
