div的隐藏与显示效果出不来，alert后发现方法是进去了，但是div是动都没动！



    <title>无标题页</title>

    <link href="../AdminService/Administer/css1/left_css.css" rel="stylesheet" type="text/css" />

    <style type="text/css">

    li{

    list-style-image:url(../AdminService/../AdminService/images/closed.gif);}

    ul{

    text-align:left;

    }

    </style>

    <script>

      function show(div){

          id=eval(div.id+div.id.substring(3,4));

        if(id.style.display == "none")

          {

           alert("block");

           id.style.display == "block"

          }else

          {

           alert("none");

           id.style.display == "none"

          }

      }

    </script>

</head>

<body>

    <form id="form1" runat="server">

    <div style="width:175px; text-align:center">

        <div id="div1" onclick="show(this)" style="width:162px; height:22px; background-image:url(../AdminService/images/left_tt.gif);" class="STYLE1">成员管理</div>

        <div id="div11" style="width:162px">

         <ul>

            <li>添加成员</li>

            <li>成员浏览</li>

         </ul>

        </div>

    </div>

    </form>

</body>

</html>
