this need.

source: open custom popup on browser window/tab close

jsfiddle: http://jsfiddle.net/sqamg/5/

var popit = true; window.onbeforeunload = function() { if(popit == true) { popit = false; homecoming "are sure want leave?"; } }

edit

use html5 web storage simulate sessions within browser. here want utilize sessionstorage rather localstorage session ends when browser window closed.

if sessionstorage variable set, not start popup, otherwise allow popup code execute.
