[removed] sharing data between tabs [closed]

Answer 1

You could use AJAX (as everyone else is suggesting) or cookies if the data is small. See http://www.quirksmode.org/js/cookies.html for fun with cookies.

I'm sticking to the shared local data solution mentioned in the question using localStorage. It seems to be the best solution in terms of reliability, efficiency, and browser compatibility.

localStorage is implemented in all modern browsers.

The storage event fires when other tabs makes changes to localStorage. This is quite handy for communication purposes.

Answer 3

The only way I can think of: constant ajax communication with the server to report any user action on the other tabs.
