As discussed on #drupal, I've created a patch to add an AJAX-based
form_autocomplete() field to the Drupal core.


The documentation of the autocomplete callback remains undocumented.
See http://drupal.org/node/22471 for more details.

I've created a demonstration page that works in a number of different
browsers:

Works on Firefox @ MacOS.

Don't mean to throw a spanner in the works, but I get an error if the
request I type does not match any in the database/ file it is looking
through.
-- Begin Error --
JavaScript
An HTTP error undefined occured.

-- End Error --


Would it be best to have it display an ' informative' error message, or
stop trying to 'guess' if it definately can't find a match?


BTW: I am using Safari 2.0 Mac OsX (you don't say :P )

The error no longer shows, so that issue seems to be fixed (in Safari 2
anyway. As far as I can tell, this is the only browser that it occcured
in).

one more nit - pressing escape should ideally caused tghe autocomplete
div to disappear. sometimes it is not wanted.


please submit a patch against HEAD, if possible.

After typing a number of short terms, I start getting incorrect results.
  It seems mostly to happen with words starting with the letter "b",
oddly enough.


In Opera, the page scrolls when you use arrows to select results.  The
cursor doesn't move to the end of the selected word after you press
Enter.  If the list is open with an item selected and you tab away, the
list doesn't disappear.


I also so some weirdness in Firefox and Opera when using the mouse to
select entries.  Sometimes the drop-down wouldn't disappear.

solon: I've fixed that on the demo page now, it seems Safari can't
access the connection status property (so it shows as "undefined").


moshe: the patch above is/was against CVS HEAD, I've just posted it
wrongly. I agree about hitting escape, so I'll try to do that one.


Junyor: I might be able to stop the scrolling, but I'll have to check
on some other things first. Which version of Opera were you using and
which OS? The dropdown hides correctly for me when I tab out in Opera 8
on Windows.


A problem I find with creating this control is that I need to
completely define my own behaviour. I'd like it to act exactly as the
user expects, so I'll try ironing out the above bugs.

I tested with Opera 8.0 and an internal build of 8.01 on Windows XP. 
I'll see if I can find a way to reproduce the problem.  E-mail me if
you have any questions about getting stuff working in Opera.
