Is there any way to use [removed] on Mobile Safari for iOS devices?

Question

Looks like Apple has disabled the window.onbeforeunload event for iOS devices (iPhone, iPad, iPod Touch). Unfortunately I can\'t find any documentation as to why this event

Answer 1

I was having the same problem. it seems safari browser in iphone triggers only focus and blur events and almost every other event is not triggered, e.g.(pagehide, pageshow, visibility change) but the good news is focus and blur event are supported and triggered on iphone, ipad & android mobiles as well.

    window.addEventListener('focus', function(){
       // do stuff
     });

   window.addEventListener('blur', function(){
       // do stuff
     });

hope this helps anyone.
