| // 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. |

| // The local array autocompleter. Used when you'd prefer to |

| // the id of the monitored textbox, and id of the autocompletion menu. |
| // The third is the array you want to autocomplete from, and the fourth |
| // is the options block. |
| // |
| // Extra local autocompletion options: |
| // - 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 |
| // 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. |
| // Defaults to true. |
| // |
| // It's possible to pass in a custom function as the 'selector' |
| // option, if you prefer to write your own autocompletion logic. |
