今天用到dTree.js,顺便研究了下。
dTree产生一个javascript树形目录结构,设置和应用都比较简单。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 >
< h1 >
   < a href ="/" >Destroydrop a> » < a href ="/javascripts/" >Javascripts a> » < a href ="/javascripts/tree/" >DTree a>    
h1>

< 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>
div>

body>
html>
 
效果图如下:

很帅吧~ 哈哈!!
 
主要用到的几个方法:
add():  添加一个节点                      id, pid, name是必选的。
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():打开所有的节点
ex:d.openAll();
 
closeAll():关闭所有的节点
ex:d.closeAll();
 
openTo():打开特定的一个节点并选中。
ex:d.openTo(4, true) 打开第4个节点并选中。
 
心动不如行动,赶快试一下吧!! 哈哈!!
