|

d86eb8c1 | Marc Dequènes (Duck) | // Specific autocompleters need to provide, at the very least,

b689e231 | Marc Dequènes (Duck) | // a getUpdatedChoices function that will be invoked every time
|
|
d86eb8c1 | Marc Dequènes (Duck) | // the text inside the monitored textbox changes. This method
|
|
b689e231 | Marc Dequènes (Duck) | // 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
|
|||
d86eb8c1 | Marc Dequènes (Duck) | // enables autocompletion on multiple tokens. This is most
|
|
// useful when one of the tokens is \n (a newline), as it
|
|||
b689e231 | Marc Dequènes (Duck) | // allows smart autocompletion after linebreaks.
