Answer 1

You can use HTML5 session Storage ,just generate an unique id and set it on the session storage ! what is cool about that each window or tab has its own session storage. for example :

if we run the following on 3 windows:

window 1: sessionStorage.setItem('key' , 'window1');

window 2: sessionStorage.setItem('key' , 'window2');

window 3: sessionStorage.setItem('key' , 'window3');

sessionStorage.getItem('key' ); <<< this will return corresponding value on window!

window 1: sessionStorage.getItem('key' ); returns window 1

window 2: sessionStorage.getItem('key' ); returns window 2

window 3: sessionStorage.getItem('key'); returns window 3

I believe you are trying to save a variable (separately on each tab/window).

sessionStorage works as charm.

The only problem you may face that browser should support HTML 5.
