I need to display a confirm dialog box before closing the browser window using javascript or PHP. The confirm box should come up when I click the close button of browser; otherwise, the dialog should not be displayed.

Thanks

This will display it when closing the browser:

window.onbeforeunload = function (event) {
  var message = 'Sure you want to leave?';
  if (typeof event == 'undefined') {
    event = window.event;
  }
  if (event) {
    event.returnValue = message;
  }
  return message;
}

With Jquery:

$(window).bind('beforeunload', function(e) {
    // Your code and validation
    if (confirm) {
        return "Are you sure?";
    }
});
