One note on TJ's post, hopefully helpful: You cannot CANCEL the unload event. If i understand them correctly, load and unload are the only native events that can't be canceled from scripts. You can perform other actions, but unload means the browser has been committed to unloading that page, regardless what else it's told to do at that point. The point of no return to let the user cancel the unload is "beforeunload" (handy, and a Microsoft creation, ironically).
And to his point, he's correct: about the only other actions you can take are cleanup/garbage collection. Not that it would matter anyway if you create new content, the page is going bye-bye. :) That all comes from a painful two weeks a few years ago before i knew about beforeunload. Still bitter at myself over that. -joe t. On Mar 10, 9:31 am, Walter Lee Davis <wa...@wdstudio.com> wrote: > On Mar 10, 2011, at 2:25 AM, T.J.
