我希望能够在浏览器窗口/选项卡关闭时执行一些操作。这应该使用 Javascript 来完成。有什么建议吗？

使用 onBeforeUnload 处理程序。看这个:

If there was a way to catch the unload and prevent it happening then popup adverts everywhere would use it to prevent you closing the popups.

A different approach would be to use the onload event for your page to go through all tags in the page and add an onclick handler which does what you want.
