检测window.location的变化
[英]Detecting changes in window.location
问题描述
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. 
我正在尝试检测window.location的变化（例如，如果用户尝试重新加载页面，则会收到通知），但是我似乎找不到解决方法。 Are there some events associated with it? 是否有与此相关的事件？
Thanks 谢谢

The unload event is fired when the user leaves the page. 当用户离开页面时，将触发unload事件。 There's also a beforeunload event in some browsers, but it's not supported in Opera . 在某些浏览器中，还有一个beforeunload事件，但Opera不支持 。
