今天用到dTree.js，順便研究了下。
dTree產生一個javascript樹形目錄結構，設置和應用都比較簡單。示例如下：
example.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Destroydrop » Javascripts » Tree</title>
<link rel="StyleSheet" href="dtree.css" type="text/css" />
<script type="text/javascript" src="dtree.js"></script>
</head>
<body>

<h2>dTree Example</h2>
<div class="dtree">
<p>
<a href="javascript: d.openAll();">open all</a> |
<a href="javascript: d.closeAll();">close all</a> |
<a href="javascript: d.openTo(11, true);">openTo</a> |<!--when tree is drawn-->
<a href="javascript: d.toString();">view</a>
</p>
<script type="text/javascript">
d = new dTree('d');
d.add(0,-1,'My example tree');
d.add(1,0,'Node 1','example01.html');
d.add(2,0,'Node 2','example01.html');
d.add(3,1,'Node 1.1','example01.html');
d.add(4,0,'Node 3','example01.html');
d.add(5,3,'Node 1.1.1','example01.html');
d.add(6,5,'Node 1.1.1.1','example01.html');
d.add(7,0,'Node 4','example01.html');
d.add(8,1,'Node 1.2','example01.html');
d.add(9,0,'My Pictures','example01.html','Pictures I\'ve taken over the years','','','img/imgfolder.gif');
d.add(10,9,'The trip to Iceland','example01.html','Pictures of Gullfoss and Geysir');
d.add(11,9,'Mom\'s birthday','example01.html');
d.add(12,0,'Recycle Bin','example01.html','','','img/trash.gif');
document.write(d);
</script>

效果圖如下：
很帥吧~ 哈哈！！
主要用到的幾個方法：
add(): 添加一個節點 id, pid, name是必選的。
原型：add(id, pid, name, url, title, target, icon, iconOpen, open)
ex：d.add(1, 0, 'My node', 'example.html', 'node title', 'mainframe', 'img/folder.gif')
openAll()：打開所有的節點
ex：d.openAll();
closeAll()：關閉所有的節點
ex：d.closeAll();
openTo()：打開特定的一個節點並選中。
ex：d.openTo(4, true) 打開第4個節點並選中。
心動不如行動，趕快試一下吧！！ 哈哈！！
