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