1.16 +Autocompleter.Base handles all the autocompletion functionality
1.17 +that's independent of the data source for autocompletion. This
1.18 +includes drawing the autocompletion menu, observing keyboard
1.19 +and mouse events, and similar.
1.20 +
1.21 +Specific autocompleters need to provide, at the very least,
1.22 +a getUpdatedChoices function that will be invoked every time
1.23 +the text inside the monitored textbox changes. This method
1.24 +should get the text for which to provide autocompletion by
1.25 +invoking this.getToken(), NOT by directly accessing
1.26 +this.element.value. This is to allow incremental tokenized
1.27 +autocompletion. Specific auto-completion logic (AJAX, etc)
1.28 +belongs in getUpdatedChoices.
1.29 +
1.30 +Tokenized incremental autocompletion is enabled automatically
1.31 +when an autocompleter is instantiated with the 'tokens' option
1.32 +in the options parameter, e.g.:
1.33 +new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
1.34 +will incrementally autocomplete with a comma as the token.
1.35 +Additionally, ',' in the above example can be replaced with
1.36 +a token array, e.g. { tokens: [',', '\n'] } which
1.37 +enables autocompletion on multiple tokens. This is most
1.38 +useful when one of the tokens is \n (a newline), as it
1.39 +allows smart autocompletion after linebreaks.

1.910 +The local array autocompleter. Used when you'd prefer to
1.911 +inject an array of autocompletion options into the page, rather
1.912 +than sending out Ajax queries, which can be quite slow sometimes.
1.913 +
1.914 +The constructor takes four parameters. The first two are, as usual,
1.915 +the id of the monitored textbox, and id of the autocompletion menu.
1.916 +The third is the array you want to autocomplete from, and the fourth
1.917 +is the options block.
1.918 +
1.919 +Extra local autocompletion options:
1.920 +- choices - How many autocompletion choices to offer
1.921 +
1.922 +- partialSearch - If false, the autocompleter will match entered
1.923 + text only at the beginning of strings in the
1.924 + autocomplete array. Defaults to true, which will
1.925 + match text at the beginning of any *word* in the
1.926 + strings in the autocomplete array. If you want to
1.927 + search anywhere in the string, additionally set
1.928 + the option fullSearch to true (default: off).
1.929 +
1.930 +- fullSsearch - Search anywhere in autocomplete array strings.
1.931 +
1.932 +- partialChars - How many characters to enter before triggering
1.933 + a partial match (unlike minChars, which defines
1.934 + how many characters are required to do any match
1.935 + at all). Defaults to 2.
1.936 +
1.937 +- ignoreCase - Whether to ignore case when autocompleting.
1.938 + Defaults to true.
1.939 +
1.940 +It's possible to pass in a custom function as the 'selector'
1.941 +option, if you prefer to write your own autocompletion logic.
1.942 +In that case, the other options above will not apply unless
1.943 +you support them.
