Detect Mobile Browser Close Event

Question

Is there any way to detect mobile browser close event? I need to forcefully delete a cookie on browser close. I have already tried my luck with window.onbeforeunload and window.unload but they doesn't work for mobile browsers. Search on the web a lot but didn't get any solution.

Thanks in advance

This wouldn't work anyway. What if I just pulled the battery? Ask yourself this: If I don't want the data to be persistent, should I *really* be storing it in a cookie? — CodingIntrigue, Feb 11 '15 at 09:00
@RGraham Its kinda flag kind thing which I need across all the pages. I am not storing any data — Ankur Aggarwal, Feb 11 '15 at 09:02
What about a session cookie then? [This question](http://stackoverflow.com/questions/15202521/simulate-session-cookies-in-mobile-sessions) is worth a read — CodingIntrigue, Feb 11 '15 at 09:04
@AnkurAggarwal, why after the close event ? the browser will remove this cookie when the tab will be closed I guess. — Hacketo, Feb 11 '15 at 09:05
@AnkurAggarwal you can use localstorage or sessionstorage in javascript to set and access data across webpages for a single session.. — Lucky, Feb 11 '15 at 09:11

I'm sorry but it's just impossible with Javascript... You can prevent the action of closing tab but not to do something when it will be close...
