I think I may have misunderstood your previous post. The way I read it
was the following:
My submit function was firing off an AJAX request, but the AJAX
request doesn't block so once it fired the request, it exited my
function. The AJAX request not being complete, the event hadn't been
stopped, so the browser goes merrily on its way submitting the form,
and my onSuccess function stops the event afterwards, only it's too
late as the form has been submitted, so stopping the event is useless.
I assumed that Form#request() did some sort of blocking magic under
the hood--i.e., it would not allow the default action until the
request had been fully processed-- although I don't know why I did,
looking back.
What you just wrote is basically what I have, only I have the event
stopped inside the onSuccess function (I guess that makes a huge
difference, though, huh?). The problem is, I only want to stop the
event if the AJAX request was successfully sent and processed;
submitting the form should be a fallback in case AJAX is not supported
or something went wrong in the request. So I don't want to
unconditionally stop the event; that's why I placed it in my onSuccess
function. Any way to do that that you know of?
Thanks,
Turner
