How to automatically log out user when browser clo

问题:

I have a chat program, which relies on whether the user is online or not to keep chatting. So I was wondering, is there a way to logout the user when he/she closes the WHOLE browser, not just the one window in like say, Safari, IE or Google Chrome?

回答1:

There's nothing available via JavaScript which can be used to detect "WHOLE browser" exits. If you need to be notified when a browser has completely exited (even defining this would be non-simplistic), consider developing browser extensions.

My browser is google chrome. i have a idea:setttings-the last settings(more settings-the last)--to logout the user when he/she closes the browser,like cookies and so on.
