I recently migrated a few of my Autocomplete plugins from the one produced by bassistance to the jQuery UI autocomplete.

How can the \"mustMatch\" and \"selectFirst\

Answer 1

I found this question to be useful.

I thought I'd post up the code I'm now using (adapted from Esteban Feldman's answer).

I've added my own mustMatch option, and a CSS class to highlight the issue before resetting the textbox value.

       change: function (event, ui) {
          if (options.mustMatch) {
            var found = $('.ui-autocomplete li').text().search($(this).val());

            if (found < 0) {
              $(this).addClass('ui-autocomplete-nomatch').val('');
              $(this).delay(1500).removeClass('ui-autocomplete-nomatch', 500);
            }
          }
        }

CSS

.ui-autocomplete-nomatch { background: white url('../Images/AutocompleteError.gif') right center no-repeat; }
