michael@0 | 14 | // Autocompleter.Base handles all the autocompletion functionality |
michael@0 | 15 | // that's independent of the data source for autocompletion. This |
michael@0 | 16 | // includes drawing the autocompletion menu, observing keyboard |
michael@0 | 17 | // and mouse events, and similar. |
michael@0 | 18 | // |
michael@0 | 19 | // Specific autocompleters need to provide, at the very least, |
michael@0 | 20 | // a getUpdatedChoices function that will be invoked every time |
michael@0 | 21 | // the text inside the monitored textbox changes. This method |
michael@0 | 22 | // should get the text for which to provide autocompletion by |
michael@0 | 23 | // invoking this.getToken(), NOT by directly accessing |
michael@0 | 24 | // this.element.value. This is to allow incremental tokenized |
michael@0 | 25 | // autocompletion. Specific auto-completion logic (AJAX, etc) |
michael@0 | 26 | // belongs in getUpdatedChoices. |
michael@0 | 27 | // |
michael@0 | 28 | // Tokenized incremental autocompletion is enabled automatically |
michael@0 | 29 | // when an autocompleter is instantiated with the 'tokens' option |
michael@0 | 30 | // in the options parameter, e.g.: |
michael@0 | 31 | // new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' }); |
michael@0 | 32 | // will incrementally autocomplete with a comma as the token. |
michael@0 | 33 | // Additionally, ',' in the above example can be replaced with |
michael@0 | 34 | // a token array, e.g. { tokens: [',', '\n'] } which |
michael@0 | 35 | // enables autocompletion on multiple tokens. This is most |
michael@0 | 36 | // useful when one of the tokens is \n (a newline), as it |
michael@0 | 37 | // allows smart autocompletion after linebreaks. |
