Holy ##### it even works in PHP:

public function waitForAjax()
{
    while(true)
    {
        $ajaxIsComplete = array(
            'script' => 'return jQuery.active == 0',
            'args' => array()
        );
        $ajaxIsComplete = $this->execute($ajaxIsComplete);
        if ($ajaxIsComplete) {
            break;
        }
    }
}

Thank you :)
