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

// The local array autocompleter. Used when you'd prefer to | ||||
// inject an array of autocompletion options into the page, rather | ||||
// than sending out Ajax queries, which can be quite slow sometimes. | ||||
// | ||||
// The constructor takes four parameters. The first two are, as usual, | ||||
// the id of the monitored textbox, and id of the autocompletion menu. | ||||
// The third is the array you want to autocomplete from, and the fourth | ||||
// is the options block. | ||||
// | ||||
// Extra local autocompletion options: | ||||
// - choices - How many autocompletion choices to offer | ||||
// | ||||
// - partialSearch - If false, the autocompleter will match entered | ||||
// text only at the beginning of strings in the | ||||
// autocomplete array. Defaults to true, which will | ||||
// match text at the beginning of any *word* in the | ||||
// strings in the autocomplete array. If you want to | ||||
// search anywhere in the string, additionally set | ||||
// the option fullSearch to true (default: off). | ||||
// | ||||
// - fullSsearch - Search anywhere in autocomplete array strings. | ||||
// | ||||
// - partialChars - How many characters to enter before triggering | ||||
// a partial match (unlike minChars, which defines | ||||
// how many characters are required to do any match | ||||
// at all). Defaults to 2. | ||||
// | ||||
// - ignoreCase - Whether to ignore case when autocompleting. | ||||
// Defaults to true. | ||||
// | ||||
// It's possible to pass in a custom function as the 'selector' | ||||
// option, if you prefer to write your own autocompletion logic. | ||||
// In that case, the other options above will not apply unless | ||||
// you support them. | ||||
