I need to perform some DB operation when Browser Close or Tab Close button is clicked.

If I use onbeforeunload event then its working but the problem is when I clicked Browser Reload button the event is also firing.

So how to identify which browser button is clicked and how to perform this operation.

Hello Suraj Kumar,

This code will work for all the cases Browser Close/Tab close/ Reload click but I dont want to fire event when Reload button clicked.

As I want to insert DB operation only when Browser Close/Tab close clicked.

You can try this
window.onbeforeunload = function (event) {
    var message = 'Important: Please click on \'Save\' button to leave this page.';
    if (typeof event == 'undefined') {
        event = window.event;
    }
    if (event) {
        event.returnValue = message;
    }
    return message;
};
OR
$(document).ready(function()
{
    $(window).bind("beforeunload", function() {
        return confirm("Do you really want to close?");
    });
});
Hope this will help you.
