Does anyone know if the onbeforeunload event is supported on the iPad and/or if there's a different way to use it?
I've tried pretty much everything, and it seems like the onbeforeunload event is never triggered on the iPad (Safari browser).
Specifically, this is what I've tried:
window.onbeforeunload = function(event) { event.returnValue = 'test'; }window.onbeforeunload = function(event) { return 'test'; }window.onbeforeunload = function(event) { alert('test')'; }<body onbeforeunload="..."> All of these work on FF and Safari on the PC, but not on the iPad.
Also, I've done the following just after loading the page:
alert('onbeforeunload' in window); alert(typeof window.onbeforeunload); alert(window.onbeforeunload); Respectively, the results are:
trueobjectnullSo, the browser does have the property, but for some reason it doesn't get fired.
The ways I try to navigate away from the page are by clicking the back and forward buttons, by doing a google search in the top bar, by changing location in the address bar, and by clicking on a bookmark.
Does anyone have any idea about what's going on? I'd greatly appreciate any input.
Thanks

Android's browser appears to support it just fine, and the Safari desktop application also supports the onbeforeunload event without issue. This is a duplicate of window. onbeforeunload not working on the iPad? Does this answer your question?
The onbeforeunload event occurs when the document is about to be unloaded. This event allows you to display a message in a confirmation dialog box to inform the user whether he/she wants to stay or leave the current page. The default message that appears in the confirmation box, is different in different browsers.
This bit of JavaScript works for me on Safari and Chrome on ipad and iphone, as well as desktop/laptop/other browsers:
var isOnIOS = navigator.userAgent.match(/iPad/i)|| navigator.userAgent.match(/iPhone/i); var eventName = isOnIOS ? "pagehide" : "beforeunload"; window.addEventListener(eventName, function (event) { window.event.cancelBubble = true; // Don't know if this works on iOS but it might! ... } ); If you love us?
