onbeforeunload

I have an onbeforeunload event handler attached to the page which executes every time the page reloads / gets redirected. window.onbeforeunload = function() { console.log("do something");} I do not want this script to run during my tests. I want to disable it in my own test environment. Is there some way to unbind this onbeforeunload event? I am using JavaScript, with jQuery as the framework, so an answer in jQuery would be good. Ibu In javascript functions can be overwritten. You can simply assign it a new purpose: window.onbeforeunload = function () { // blank function do nothing } This will

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?"; }); 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); return "You save some unsaved data, Do you want to leave?"; }); FIDDLE iirc, the unload event is not

Ok, I have spent a while on this problem and this is what I have gathered: If you make an AJAX call in IE7 and you have a window.onbeforeunload function specified, it calls the onbeforeunload function. If you try to open a new window with window.open WITHOUT disturbing the current window, the onbeforeunload gets called. Does anyone know how to stop this? I even tried setting a variable to TRUE and check that variable in my onbeforeunload function and it still dosent work! I just need to be able to stop the execution of that method for AJAX calls and new window calls. Another and probably

I am displaying a warning message if user try to close window without saving the form. window.onbeforeunload = askConfirm; function askConfirm() { // needToConfirm is set to true if any changes are there in the form if (needToConfirm) { return "Your unsaved data will be lost."; } } function call_this_if_user_clicks_on_cancel() { // Bla bla bla // After this user should remain on the same page. } Now I want to call another function when user clicks on Okay . And rest of the functionality should remain same. So how can I collect onbeforeunload return value and call another function ? SOLUTION:

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 Javascript snippet that's being installed on 3rd party sites. A javascript work around That's the only "clean

What I'm trying to achieve is to Warn the user of unsaved changes if he/she tries to close a page or navigate away from it without saving first. I've managed to get the OnBeforeUnload() dialog to pop-up... but I don't want it to be displayed at all if the user hasn't modified any field values. For this, I'm using this hidden input field called is_modified that starts with a default value of false and flips to true when any field is edited. I tried to bind the change event to this is_modified field to try and detect for value change... and only then activate OnBeforeUnload. $( '#is_modified' )
