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.
