    }else{
        currentWindowScrollY = document.documentElement.scrollTop;
        targetWindowScrollY = Element.cumulativeOffset(myElement)[1]-window.height()+myElement.getHeight();
        if(targetWindowScrollY>currentWindowScrollY){
            window.scrollTo(window.scrollX, targetWindowScrollY);
        }
    }
}
