下載一個dtree即可實現,應用如下:
<%@page contentType= "text/html;charset=GB2312 "%>
<%@page language= "java "%>
<%@page import= "java.util.* "%>
<%@page import= "java.sql.* "%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN " "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd ">
<html>
<head>
<title> dtree樹狀檢視 </title>
<link rel= "StyleSheet " href= "dtree.css " type= "text/css "/>
<script type= "text/javascript " src= "dtree.js "> </script>
<input type=hidden name=selid id=selid>
<br>
</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
</script>
</div>
</table>
</body>
</html>
真實資料可從資料庫中讀取後添加到節點中,你可以適當修改
