ExtJS：处理浏览器退出事件（点击交叉出口） [英] ExtJS : handling browser exit event (click on cross-exit)

问题描述

首先，谢谢你阅读我的问题。
我想知道是否有任何方法来处理浏览器退出事件。

例如，我想在用户点击时发送查询在交叉出口或只是关闭浏览器。

非常感谢。

我还没有给这个解决方案进行测试。但是似乎有可能。

这是对 onbeforeunload 事件处理程序的更深入的讨论。

然后总是有一个 quirksmode 。不幸的是，加载/卸载事件尚未被Quirksmode覆盖。如页面所述：

我还没有测试加载和卸载事件;他们将被添加到表格。

First of all, thank you for reading my question. I would like to know if there is any way to handle the browser exit event.

For example, I would like to send a query when the user click on the cross-exit or simply close his browser.

Thanks a lot.

I haven't given this solution a test-run yet. But it seems possible.

Here's a more in-depth discussion on the onbeforeunload event handler. http://bytes.com/topic/javascript/insights/825556-using-onbeforeunload-javascript-event

And then there's always quirksmode. Unfortunately the load/unload events are not yet covered by quirksmode. As stated on the page:

I haven’t tested the load and unload events yet; they’ll be added to the table later on.
