When the applet is uploading onbeforeupload doesn't fire
Posted: Wed Jul 07, 2010 2:27 pm
I use onbeforeupload to detect when the page is about to be closed or refreshed. This works fine except when the the applet is actively uploading, the event doesn't fire. My question is how can I detect when the applet is uploading to warn the user before attempting to refresh or close the window?
