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!!
