Hi Tobie,
Ah, thank you--that looks very much like what I want (I didn't know
that method was there!). I just have one problem: I want the AJAX to
post to a different script than the normal form would go to. Since
Form#request() takes its URL from the form's action, which is not the
script the AJAX should go to, I would need to change that somehow. I
suppose I could hack it and change the action attribute with
writeAttribute() before AJAX, then change it back afterwards and hope
that Form#request() gets the action at the right time (or set a
timeout), but I would hope there's a better way to override the URL it
requests. Do you know of such a way? I don't see it in the list of
standard Ajax#request() options.
Thank you very much,
Turner
