检测浏览器或制表符关闭 [英] Detect browser or tab closing

问题描述

是否有任何跨浏览器的JavaScript / jQuery代码来检测浏览器或浏览器标签是否被关闭，但是没有因为点击了链接？

Is there any cross-browser JavaScript/jQuery code to detect if the browser or a browser tab is being closed, but not due to a link being clicked?

推荐答案

如果我找到你，你想知道什么时候有效关闭标签/窗口。好吧，AFAIK是 Javascript 中检测那种东西的唯一方法 onunload & onbeforeunload 活动。

If I get you correctly, you want to know when a tab/window is effectively closed. Well, AFAIK the only way in Javascript to detect that kind of stuffs are onunload & onbeforeunload events.

不幸的是（或者幸运的是？），当您将网站放在网站上时，这些事件也会被触发链接或您的浏览器后退按钮。所以这是我能给出的最佳答案，我不认为你可以在Javascript中原生检测到纯粹的 close 。如果我在这里错了，请纠正我。

Unfortunately (or fortunately?), those events are also fired when you leave a site over a link or your browsers back button. So this is the best answer I can give, I don't think you can natively detect a pure close in Javascript. Correct me if I'm wrong here.
