// 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.getEntry(), 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: new Array (',', '\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.
