| // 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. | |||
| // Defaults to true. | |||

| // It's possible to pass in a custom function as the 'selector' | |||
