检测window.location中的更改 [英] Detecting changes in window.location

问题描述

我正在尝试检测window.location中的更改（例如，如果用户尝试重新加载页面时会收到通知），但我似乎无法找到方法来执行此操作。
是否有与之相关的事件？

I am trying to detect changes in window.location (for example to be notified if the user tries to reload the page) but I can't seem to find a way to do that. Are there some events associated with it?

谢谢

推荐答案

当用户离开页面时会触发卸载事件。在某些浏览器中还有一个 beforeunload 事件，但它是 Opera不支持。

The unload event is fired when the user leaves the page. There's also a beforeunload event in some browsers, but it's not supported in Opera.
