11 | // Autocompleter.Base handles all the autocompletion functionality |
12 | // that's independent of the data source for autocompletion. This |
13 | // includes drawing the autocompletion menu, observing keyboard |
14 | // and mouse events, and similar. |
15 | // |
16 | // Specific autocompleters need to provide, at the very least, |
17 | // a getUpdatedChoices function that will be invoked every time |
18 | // the text inside the monitored textbox changes. This method |
19 | // should get the text for which to provide autocompletion by |
20 | // invoking this.getToken(), NOT by directly accessing |
21 | // this.element.value. This is to allow incremental tokenized |
22 | // autocompletion. Specific auto-completion logic (AJAX, etc) |
23 | // belongs in getUpdatedChoices. |
24 | // |
25 | // Tokenized incremental autocompletion is enabled automatically |
26 | // when an autocompleter is instantiated with the 'tokens' option |
27 | // in the options parameter, e.g.: |
28 | // new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' }); |
29 | // will incrementally autocomplete with a comma as the token. |
30 | // Additionally, ',' in the above example can be replaced with |
31 | // a token array, e.g. { tokens: [',', '\n'] } which |
32 | // enables autocompletion on multiple tokens. This is most |
33 | // useful when one of the tokens is \n (a newline), as it |
34 | // allows smart autocompletion after linebreaks. |

336 | // than sending out Ajax queries, which can be quite slow sometimes. |

347 | // text only at the beginning of strings in the |
348 | // autocomplete array. Defaults to true, which will |
349 | // match text at the beginning of any *word* in the |
350 | // strings in the autocomplete array. If you want to |
351 | // search anywhere in the string, additionally set |
352 | // the option fullSearch to true (default: off). |
353 | // |
354 | // - fullSsearch - Search anywhere in autocomplete array strings. |

357 | // a partial match (unlike minChars, which defines |
358 | // how many characters are required to do any match |
359 | // at all). Defaults to 2. |
360 | // |
361 | // - ignoreCase - Whether to ignore case when autocompleting. |
