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