要素のscrollTopをwindowのscrollTopに設定するには？

Question

私は、ウィンドウの高さよりも長い固定サイドバーを持っています。現在は、がhiddenに設定されている場合、サイドバーはスクロールできません。

私はメインのスクロールバーのほかに別のスクロールバーを導入したくないので、私はプログラム的に私は同じことを達成したいfollowing plunker

$(window).scroll(function() { 
    $(".side-bar").scrollTop($(window).scrollTop()); 
}); 

などのメインコンテンツで固定サイドバーをスクロールします角度

function linkFunc(scope, element, attribute) { 
     var page = angular.element($window); 

     page.bind('scroll', function() { 

      element.scrollY = $window.scrollY 

     }); 
    } 

しかし、正しく動作しません。

私の間違いを指摘できますか？

ありがとうございました

なぜCSSを使用しませんか？

div.menu { 
 
    position: fixed; 
 
    top: 0; 
 
    left: 0; 
 
    border: 1px solid red; 
 
} 
 
div.content { 
 
    margin-left: 55px; 
 
}

<div class="menu"> 
 
    <ul> 
 
    <li> 
 
     <a>1</a> 
 
    </li> 
 
    <li> 
 
     <a>2</a> 
 
    </li> 
 
    <li>
