浏览器关闭时如何自动注销用户？ [英] How to automatically log out user when browser closes?

问题描述

我有一个聊天程序，它取决于用户是否在线以继续聊天。所以我想知道，当他/她关闭整个浏览器时，有没有办法注销用户，而不仅仅是像Safari，IE或Google Chrome这样的一个窗口？

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?

推荐答案

没有任何可用的JavaScript可用于检测全部浏览器退出。如果您需要在浏览器完全退出时收到通知（即使定义这将是非简单的），请考虑开发浏览器扩展。

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.
