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.

374// The local array autocompleter. Used when you'd prefer to
375// inject an array of autocompletion options into the page, rather
376// than sending out Ajax queries, which can be quite slow sometimes.
377//
378// The constructor takes four parameters. The first two are, as usual,
379// the id of the monitored textbox, and id of the autocompletion menu.
380// The third is the array you want to autocomplete from, and the fourth
381// is the options block.
382//
383// Extra local autocompletion options:
384// - choices - How many autocompletion choices to offer
385//
386// - partialSearch - If false, the autocompleter will match entered
387// text only at the beginning of strings in the
388// autocomplete array. Defaults to true, which will
389// match text at the beginning of any *word* in the
390// strings in the autocomplete array. If you want to
391// search anywhere in the string, additionally set
392// the option fullSearch to true (default: off).
393//
394// - fullSsearch - Search anywhere in autocomplete array strings.
395//
396// - partialChars - How many characters to enter before triggering
397// a partial match (unlike minChars, which defines
398// how many characters are required to do any match
399// at all). Defaults to 2.
400//
401// - ignoreCase - Whether to ignore case when autocompleting.
402// Defaults to true.
403//
404// It's possible to pass in a custom function as the 'selector'
405// option, if you prefer to write your own autocompletion logic.
406// In that case, the other options above will not apply unless
407// you support them.
