Can we capture the same browser closing event without using “onunload”

Question

Actually using the window.close , we can control whether browser is closed or not, but it works only for pop-ups created by the browser.

So, are there any ways to listen to the closing event of the browser without using onunload ? Because we don't want things to be executed when back , refresh or forward actions occur.

Please also reply if you know specifics regarding Firefox.

Thanks in advance!

Answer 1

You are trying to manipulate the EXPECTED behaviour of the browser, essentially taking away people's ability to navigate. Fortunately browser developers were smart enough to disallow this - so the answer is NO.

Answer 2

我还想以与onunload不同的方式关闭浏览器/选项卡，因为在这种情况下我想执行一些验证，但不是页面中存在的所有onunload可能性，这对我来说是一个有效的用例。
