</head>
<body>
<img   src= "images/galaxy.bmp "   width=120   height=50   border=0   usemap= "images/galaxy.bmp "   alt= "image ">
<h3> 系統 </h3>
<table>
<div   class= "dtree ">
<p>
<a   href= "javascript:   d.openAll(); "> 全部展開 </a>

<a   href= "javascript:   d.closeAll(); "> 全部收合 </a>
</p>
<script   type= "text/javascript ">
    d   =   new   dTree( 'd ');
    d.add( "root0 ",-1, '系統 ', 'pages/treejs.jsp ');//添加根節點
    d.add( "root1 ", "root0 ", '中心裝置 ', 'pages/treejs.jsp ', ' ', ' ', 'images/cd.gif ', 'images/cd.gif ');添加子節點
        document.write(d);//輸出顯示樹狀圖
