    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.

   377 // - choices - How many autocompletion choices to offer
   378 //
   379 // - partialSearch - If false, the autocompleter will match entered

   381 //                    autocomplete array. Defaults to true, which will

   386 //
   387 // - fullSsearch - Search anywhere in autocomplete array strings.
   388 //
   389 // - partialChars - How many characters to enter before triggering
   390 //                   a partial match (unlike minChars, which defines
   391 //                   how many characters are required to do any match
   392 //                   at all). Defaults to 2.
