| 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. |
