With the event beforeunload
, i can display a message when the page is to be canceled or updated.
$(window).on('beforeunload', function () {
return 'Testando';
});
But the client for whom I usually develop systems do not like many of the layouts of the alert
, confirm
or prompt
javascript.
So I’d like to, at this event of beforeunload
, put a modal displaying a message in place of that alert
appearing.
Is there any way to do this ? Is there any way to use the event beforeunload
, without posting the message of alert
?
There’s no way I can explain why Run script js when trying to close the window
