Coding Chat Application For My Website .. Need Help !!

[rajdevsohail]

i am trying to code a chat app for my social network and i am using the following module ..

http://anantgarg.com/2009/05/13/gmail-facebook-style-jquery-chat/

i have coded the rosters(manage who is online) for it ..

but those rosters work only on login/logout .. on login it makes an entry for username in a database and then all the online friends are displayed on the page that appears after login and the record is deleted when the user logouts . but when a user directly closes the browser the database record is not deleted ..

is there a way to do the deletion when the browser closes without logout .. or can anyone give me a tutorial for creating the rosters (manage who is online and so on ..) ..

thanx in advance ,
Sohail .. :)

Logout on close browser is difficult. JS needs to hijack your browser:

<script>
window.onbeforeunload = confirmExit; 
function confirmExit()
{ 

return "Put your message here!";

}
</script>
