                ajax.onreadystatechange = function () {
    
                    if ( ajax.readyState == 4 ) { //response ready
    
                        if ( ajax.status == 200 ) { //success
    
                            if ( settings.success ) settings.success( ajax.responseText, ajax.statusText );
