onbeforeunload

问题 Yes, I realize this is horrible UI and bad accessibility wise, but I am forced to seek out the options due to contracted work ( to which I didn't initially agree upon and am stuck with ). I know that you can assign an event handler to onbeforeunload like: window.onbeforeunload = function() { return 'You have unsaved changes!'; } That would bring about a dialog generated by the OS/browser which cannot be customized. It would ask you to Cancel your request or go on. So far it seems the only way

问题 Is there any way that I could detect in the following code that either user clicked "leave page" or "stay on page" button ? $(window).on('beforeunload', function (){ return "You save some unsaved data, Do you want to leave?"; }); 回答1: With a few hacks you can at least determine if the user stayed. If the user left the page, there's not much you can do about that : var timeout; $(window).on('beforeunload', function (){ timeout = setTimeout(function() { // user stayed, do stuff here }, 1000);

问题 I have an onbeforeunload event that's supposed to get triggered any time a user goes to a new page. It works well enough, but I've found that it also gets triggered in Chrome any time a user downloads a file from the page they're on. I'd like to be able to tell if the event is getting fired because it's being triggered by a file download. What's the best way to do that? EDIT: As a clarification, I don't own the site that I'm listening to onbeforeunload on. The event is listened to by a

问题 I have an AJAX-based grid control. We hook into the window.onbeforeunload event to check if they have unsaved data and if so present them with a message "Are you sure you want to navigate away...you have unsaved data...". All this is good. But AJAX calls also trigger window.onbeforeunload and so if the grid has unsaved data and we make an AJAX call (such as to delete a row in another grid) the user gets the "Are you sure you want to navigate away...you have unsaved data..." message which is

问题 How to Handle below IE Popup in Selenium 回答1: The Internet Explorer popup with text as Are you sure you want to leave this page? is the result of WindowEventHandlers.onbeforeunload onbeforeunload The onbeforeunload property of the WindowEventHandlers mixin is the EventHandler for processing beforeunload events.

问题 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(

问题 This question already has answers here : How to disable beforeunload action when user is submitting a form? (6 answers) Closed 4 years ago . I am using window.onbeforeunload to prevent the user from navigating away after changing values on a form.

问题 I have this little piece of code: <script> $(window).bind('beforeunload', function() { $.ajax({ async: false, type: 'POST', url: '/something' }); }); </script> I wonder, how could I disable this request when user hits the submit button. Basically something like here, on SO. When your asking a question and decide to close the page, you get a warning window, but that doesn't happen when you're submitting the form. 回答1: Call unbind using the beforeunload event handler: $('form#someForm').submit
