onbeforeunload

This question already has an answer here: How to disable beforeunload action when user is submitting a form? 6 answers I am using window.onbeforeunload to prevent the user from navigating away after changing values on a form. This is working fine, except it also shows the warning when the user submits the form (not desired). How can I do this without showing the warning when the form submits? Current code: var formHasChanged = false; $(document).on('change', 'form.confirm-navigation-form input, form.confirm-navigation-form select, form.confirm-navigation-form textarea', function (e) {

How do I determine if onbeforeunload was caused by clicking the close button or a page refresh or generally what event caused onbeforeunload? here is a snippet: window.onbeforeunload = function( e ){ if( !e ) e = window.event; // insert code to determine which is the source of the event } Please help me. Referring to various articles and doing some trial and errors, finally developed this idea which works perfectly for me just the way i wanted it to happen.

I'm using the code that netadictos posted to the question here . All I want to do is to display a warning when a user is navigating away from or closing a window/tab. The code that netadictos posted seems to work fine in IE7, FF 3.0.5, Safari 3.2.1, and Chrome but it doesn't work in Opera v9.63. Does anyone know of way of doing the same thing in Opera? Thx, Trev onbeforeunload is now supported in Opera 15 based on the WebKit engine but not in any prior versions based on Presto. Opera does not support window.onbeforeunload at the moment. It will be supported in some future version, but has not

I am opening a popup window and attaching an onbeforeunload event to it like this: win = window.open("http://www.google.com", "", "width=300px,height=300px"); win.onbeforeunload = function() { //do your stuff here alert("Closed"); }; If I leave the URL empty, the new popup opens with "about:blank" as the address but when I close it, I see the alert. If I open in as you see it (with an external URL), once it's closed, I cannot see the alert anymore. Any idea why this is happening? As mentioned, same origin policy prevents Javascript from detecting such events. But there's a quite simple

So, I've got a handy little bit of functionality in place in a jQuery Mobile app that lets the user know if he/she is navigating away from the page, as this will trigger a log off. In simplified form: $(window).bind('beforeunload', function() { return "Navigating away from this page will log you off. Are you sure you want to continue?"; }); $(window).unload(function() { logoff(); }); This works just great in both Safari and Chrome on my laptop. However, it doesn't appear to work on the iPhone simulator. Does the mobile browser included in iOS (I know it's Safari, but presumably a different

I've got an editor in javascript on my webpage and I would like to ask user if he/she wants to leave the page even if there are unsaved changes. I know I can add custom message to the "onbeforeunload dialog" this way: window.onbeforeunload = function() { return 'You have unsaved changes!'; } ( Source ) but I want to display the dialog only where there really are some unsaved changes. How to do that? Thanks!

Hi I would like to customize my pop up for leaving a page, is there any simple way to do that? I am using simple jQuery $(document).ready(function() { var myPopUp = $('#pop-up').css('display', 'block'); $(window).bind('beforeunload', function(){ return 'load my pop up here instead of the default browser message'; }); }); my html for the pop up is which is hidden by default <div id="pop-up"> <h2>Are you sure wanna leave</h2> <a href="#">Leave</a> <a href="#" class="close">Stay</a> </div> Thanks Short answer: You can't .
