| // 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.

 | |
| // - choices - How many autocompletion choices to offer
 | |
| //
 | |
| // - partialSearch - If false, the autocompleter will match entered
 | |
| //                    text only at the beginning of strings in the
 | |
| //                    autocomplete array. Defaults to true, which will

 | |
| //                    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
