+// 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.

|

|

|
|
+// a partial match (unlike minChars, which defines

|
|
+// how many characters are required to do any match
|
|
|
+// at all). Defaults to 2.
