Answer 1

Pretty simple try this

$(window).on('beforeunload', function() { 
return 'Are you sure want to logout ?'; 
});

$(window).unload(function() { 
debugger;    // when closing window debugger will hit here
});

Answer 2

If you want to know when a window or tab is closed then use unload or onbeforeunload , these events are fired too, when you leave the site by a link.

The API for jQuery unload() : https://api.jquery.com/unload/

...and pure javascript: https://developer.mozilla.org/de/docs/Web/API/WindowEventHandlers/onbeforeunload
