Mini AJAX - make the most of Web 2.0

miniAJAX($('myForm'), myCallback).call();

A sample callback may be:

var shopminiAJAX = {
		/* callerID has to be set */
		callerID: '_ajax_caller_identifier',
 
		/* processResponse has to be set */
		processResponse: function ( data ) {
			var returnData = data.parseJSON();
			alert(returnData);
		}

Finally a corresponding action plugin function:

$controller->register_hook(	'AJAX_CALL_UNKNOWN', 'BEFORE',
				$this, '_my_ajax_functions');
 
function _my_ajax_functions(&$event, $args) {
	if ( $event->data != '_ajax_caller_identifier' ) return;
	require_once( DOKU_INC . 'inc/JSON.php');
	$json = new JSON();
	$_REQUEST = (array)$json->dec($_REQUEST['q']);
 
	header('Content-Type: text/html; charset=utf-8');
	foreach ( $_REQUEST AS $key => $value ) {
		$output .= "$key -> $value\n";
	}
 
	print $json->enc($output);
	return;
}
