// 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.

397 |
// a partial match (unlike minChars, which defines
