// 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.

//
|

// - 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.
