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.
