r163 | // the text inside the monitored textbox changes. This method | |

pramook
|
r0 | // 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 | |||
|
jittat
|
r163 | // enables autocompletion on multiple tokens. This is most | |
| // useful when one of the tokens is \n (a newline), as it | |||

pramook
