Rails spinoffs - Feb 2006 - modify the auto-complete to use the results already retrieved to create the next set of suggestions

Hi everyone,

I want to modify the auto-complete to use the results already retrieved to
create the next set of suggestions.

For example, if the user types ''j'', the ajax request fetches
responses for ''j''.Now if the user types ''o''
the input becomes ''jo''.
I want to use the results from ''j'' and narrow down the
suggestion to ''jo'' instead of sending a fresh request for
''jo'' to server.

Any suggestions on how I can do this ?

Thanks,
Shyam

You could certainly cache the results in an array of your own, but the real
usefulness of the autocompleter is for large result sets. That is, if you
type "j", there could be several hundred results...and only the first
(say)
10 results will be returned. Then, as more letters are added, a better
search parameter is created, and the next top 10 will be returned. Since you
never return all the results, you won''t be able to "cache and
search" them
in the manner you''re suggesting.

Not to say that you CAN''T do what you''re suggesting...but if
you have few
enough items that you''re able to return all the matches after a single
character, perhaps a standard JS array/filtering would work better?
