I use this one 

 window.onbeforeunload = function (event) {
            event = event || window.event;
            if ((event.clientX < 0) || (event.clientY < 0) || event.clientY < -80) { 
}

Refer this question on how to capture the browser close event.

Now what you can do is do an AJAX call in the event to call a Web Service, which in-turn does update your database accordingly.

Refer this question to prevent browser being closed while you are in middle of an AJAX request.
