I need to alert users about unsaved changes before they leave a page.But i dont want to use the default alert box for that . Suppose consider calling showalertPopup() Function displays the my designed alert box . How to replace it with the default alert box

 window.onbeforeunload = function() {
        $alertMsg = "Are you sure wanna leave this Page ?"
        return $alertMsg;
    };

`errorMessages` must return a string. That's said, you cannot use an alert box instead of the native prompt box – A. Wolff Apr 29 '14 at 11:42
Changed ! errorMessages will return string only . Theres no way of repacing native prompt box ah ? Any jquery plugins like that ? – user3383301 Apr 29 '14 at 11:45

@user3383301 jQuery is javascript. What cannot be done in javascript, cannot be done using jQuery – A. Wolff Apr 29 '14 at 11:49
@A.Wolff : Okay thanks :( – user3383301 Apr 29 '14 at 11:51
The easiest way is to hide and display a div instead of using an alert. then you can customise your div – Whitney R. Apr 29 '14 at 12:12
