How to create popup window when browser close

问题

I want to open popup window when browser closed or closed tabs.

回答1:

window.onUnLoad= function (evt) { 
 //your code goes here
 window.open("yourpage/some link");
}

EDIT NOTE: Now it will be called on onUnload event of browser. Try now

Try window.onclose event:
