onbeforeunload

I've been using this code for some time and it worked fine until yesterday: window.onbeforeunload = function() { return "¡Atención! Si continúas no podrás volver atrás y podrías perder datos. Revisa todos los campos y termina el trabajo antes de moverte de esta página. ¿Seguro que quieres continuar?"; } The problem now is that Chrome shows this: But Edge shows it the right way: What am I doing wrong? Note: Language is not the problem because I've tried with both English and Spanish. You're not doing anything wrong. Google has decided to do what Mozilla did and not allow you to show a custom

I'm trying to post data when a user leaves my page. I have finally managed to find a working solution, however, it shows a confirmation dialog when the user leaves. I have tried return null; but it didn't work.

This means the return value of the handler must be undefined (not '' , false , or

I know, that Opera doesnt support JS onbeforeunload message and will not support it. But is there any way to make it work somehow? Or maybe some jQuery plugins can make it work and let script know if window is going to close? I found only way to make onclick for every a tag, but this is not the complete solution. Upgrade to Opera 15. onbeforeunload is now supported in that version because they moved to the WebKit engine.

I have a simple angular app that has two views that are loaded using ngRoute. I need to do some clean up on the server when the user navigates between views and when the user leaves the page (refreshes window, closes tab, or closes browser). My first stop was here: Showing alert in angularjs when user leaves a page . It solved the first case where the user navigates between views. I've handled the clean up like this: $scope.$on('$locationChangeStart', function (event) { var answer = confirm("Are you sure you want to leave this page?") if (answer) { api.unlock($scope.id); //api is a service

This question already has an answer here: Crossbrowser onbeforeunload? 5 answers jQuery onbeforeunload is not working in Chrome and Firefox. It works properly in IE and Safari. jQuery(window).bind('onbeforeunload' ,function () { mymethod(); }); Above code works properly in IE and in Safari but not in Firefox and Chrome.

In a web app I'm working on, I'm capturing onBeforeUnload to ask the user whether he really wants to exit. Now, if he decides to stay, there are a number of things I'd like to do. What I'm trying to figure out is that he actually chose to stay. I can of course declare a SetTimeout for "x" seconds, and if that fires, then it would mean the user is still there (because we didn't get unloaded). The problem is that the user can take any time to decide whether to stay or not... I was first hoping that while the dialog was showing, SetTimeout calls would not fire, so I could set a timeout for a
