- // Autocompleter.Base handles all the autocompletion functionality
- // that's independent of the data source for autocompletion. This
- // includes drawing the autocompletion menu, observing keyboard
- // and mouse events, and similar.
- //
- // Specific autocompleters need to provide, at the very least,
- // a getUpdatedChoices function that will be invoked every time
- // the text inside the monitored textbox changes. This method
- // should get the text for which to provide autocompletion by
- // invoking this.getToken(), NOT by directly accessing
- // this.element.value. This is to allow incremental tokenized
- // autocompletion. Specific auto-completion logic (AJAX, etc)
- // belongs in getUpdatedChoices.
- //
- // Tokenized incremental autocompletion is enabled automatically
- // when an autocompleter is instantiated with the 'tokens' option
- // in the options parameter, e.g.:
- // new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
- // will incrementally autocomplete with a comma as the token.
- // Additionally, ',' in the above example can be replaced with
- // a token array, e.g. { tokens: [',', 'n'] } which
- // enables autocompletion on multiple tokens. This is most
- // useful when one of the tokens is n (a newline), as it
- // allows smart autocompletion after linebreaks.

- // text only at the beginning of strings in the
- // autocomplete array. Defaults to true, which will
- // match text at the beginning of any *word* in the
- // strings in the autocomplete array. If you want to
- // search anywhere in the string, additionally set
- // the option fullSearch to true (default: off).
- //
- // - fullSsearch - Search anywhere in autocomplete array strings.
- //
- // - partialChars - How many characters to enter before triggering
- // a partial match (unlike minChars, which defines
- // how many characters are required to do any match
- // at all). Defaults to 2.
- //
- // - ignoreCase - Whether to ignore case when autocompleting.
