Detect via js a browser window/tab close event

Question

I'm trying to detect if a user is leaving my websites. Like a window/tab close event of the webbrowser or by following a link to a other domain.

In some searches I found some solutions, but they alert ever when a link is clicked, also on my pages. As example I tried out this:

window.onbeforeunload = function(event) {

event = event || window.event;

var confirmClose = 'Are you sure?';

// For IE and Firefox prior to version 4
if (event) {
   event.returnValue = confirmClose;
}

// For Safari
return confirmClose;

}

So what do I have to modify so that the alert is deactivated when I'm browsing through my domain?

Thanks Oliver

you can't do it that way, the function will prevent what you are trying to do — Varun Kumar, May 11 '16 at 10:30

You can't know where you are going when the onbeforeunload fires. And the purpose is basically to prevent exactly what you are trying to achieve.
