在refress上显示自定义弹出窗口，并在javascript / jquery中关闭浏览器/选项卡

Question

I want to open popup when closing the tab or browser first time and get the user review. I used onbeforeunload() , but I need to handle page refresh and tab close deferent different event.

Answer 1

Short answer: You can't.

Longer answer: For rather obvious "security" reasons it is very limited what you can do when a user tries to navigate away from a page / close a tab or in any other way leave the site.

The reason is that browsers want to make absolutely sure that you cannot prevent the user from closing a tab or window that he / she wants to close.

Therefore the onbeforeunload javascript event - and by extension the beforeunload jQuery event - are extremely limited in what they can do. One of the things they definitely cannot do is prevent the page from closing - except using one very standardized and rather boring method the browser (usually) allows.
