I'm running into something similar. The result handler has no
corrollary for cases where you aren't using mustMatch, and want to
take some action if the user doesn't select something. For example, I
want to put the ID from the extra data value into a hidden field when
it matches, but want to clear that hidden field if it doesn't match.
I don't see a foolproof way to do this right now via events from the
autocomplete. So, instead I have a second JavaScript function that is
attached to the blur for the autocomplete field that goes and looks up
the value in the autocomplete field to see if it exists, and takes
that result and populates the hidden field (or clears it, if no
match). But, this is clearly poor, given that it causes a second AJAX
request when none is actually needed.
So, is there a way to get an event in the case where result won't get
called? Or, can someone point me at where I might hook into that in
the autocomplete code? I'm not as experienced with JavaScript, so
haven't (on relatively quick glance) found the appropriate place to
hook in to add another hook/callback.
