Question

I have question related to Browser close event..

How to capture the Browser close event without refresh event.

Thanks in Advance.

Answer 1

Using window.onbeforeunload but this will also be triggered when you reload the browser or moving to a different page by clicking on a link.

window.onbeforeunload = function(e) {
  var dialogText = 'Dialog text here';
  e.returnValue = dialogText;
  return dialogText;
};

Note: window.onbeforeunload will not work on touch devices except Android.

Answer 2

Try this one

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;
};

$(function () {
    $("a").not('#LogOut').click(function () {
        window.onbeforeunload = null;
    });
    $(".btn").click(function () {
        window.onbeforeunload = null;
});
});
