把dtree.css 和dtree.js及img文件夹放到页面的根文件夹下就可以用！
Dtree所引用的css
一：dtree.css
.dtree {//定义目录树节点的字体，字号，颜色
font-family: Verdana, Geneva, Arial, Helvetica, sans-serif;
font-size: 12px;
color: #006600;
white-space: nowrap;
}
.dtree img {//定义选用节点图标的样式，位置
border: 0px;
vertical-align: middle;
}
.dtree a {//
color: #006600;
text-decoration: none;
}
.dtree a.node, .dtree a.nodeSel {
white-space: nowrap;//表格随着文字自动伸展（如果未设置TD宽度，则noWrap属性是起作用的；如果设置了TD宽度，则noWrap属性是不起作用的。）
padding: 0px 0px 0px 0px;
}
.dtree a.node:hover, .dtree a.nodeSel:hover {
color: #006600;
text-decoration: none;
}
.dtree a.nodeSel {//节点选中后的节点背景颜色
background-color: #c0d2ec;
}
.dtree .clip {
overflow: hidden;
}
二：tree.css
body {SCROLLBAR-FACE-COLOR:#D2FFD2;
SCROLLBAR-HIGHLIGHT-COLOR: #8AA583;
SCROLLBAR-SHADOW-COLOR: #8AA583;
SCROLLBAR-3DLIGHT-COLOR: #ffffff;
SCROLLBAR-ARROW-COLOR: #8AA583;
SCROLLBAR-TRACK-COLOR: #E1FFE1;
SCROLLBAR-DARKSHADOW-COLOR: #ffffff;
background-attachment: fixed;
//scroll : 背景图像是随对象内容滚动
//fixed : 背景图像固定
background-repeat: no-repeat;
//background-repeat : repeat | no-repeat | repeat-x | repeat-y
//repeat : 背景图像在纵向和横向上平铺
//no-repeat : 背景图像不平铺
//repeat-x : 背景图像在横向上平铺
//repeat-y : 背景图像在纵向平铺
background-color: EFF7F7;
}
Dtree目录树的总结
<link href="/jingjindatabase/pub/css/dtree.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
tree = new dTree('tree');
tree.add("1","-1","京津","","","","","",true);
tree.add("11","1","A","","","","","",true);
tree.add("110","11","A-1","content.jsp?moduleName=XXX","","mainFrame");
tree.add("111","11","A-2","javascript:void(0)","","链接在哪里显示");
tree.add("112","11","A-3","javascript:void(0)","","mainFrame");
tree.add("113","11","A-4","/.jsp","","mainFrame");
tree.add("114","11","A-5","/.jsp","","mainFrame");
tree.add("115","11","A-6","/.jsp","","mainFrame");
tree.add("12","1","B","","","","","",true);
tree.add("121","12","B-1","javascript:调用本页内的js函数","","mainFrame");
tree.add("122","12","B-2");
tree.add("131","13","C-1","javascript:void(0)","","mainFrame");
tree.add("132","13","C-2","javascript:void(0)","","mainFrame");
tree.add("133","13","C-3","javascript:void(0)","","mainFrame");
tree.add("141","14","D-1","javascript:void(0)","","mainFrame");
document.write(tree);
</script>
说明：这是静态的代码，动态的可用循环加入。
三：css文件的注解
1:dtree.css
.dtree {//定义目录树节点的字体，字号，颜色
font-family: Verdana, Geneva, Arial, Helvetica, sans-serif;
font-size: 12px;

white-space: nowrap;
}
.dtree img {//定义选用节点图标的样式，位置
border: 0px;
vertical-align: middle;
}
.dtree a {//

text-decoration: none;
}
.dtree a.node, .dtree a.nodeSel {
white-space: nowrap;
padding: 0px 0px 0px 0px;
}
.dtree a.node:hover, .dtree a.nodeSel:hover {
color: #006600;
text-decoration: none;
}
.dtree a.nodeSel {
background-color: #c0d2ec;
}
.dtree .clip {
overflow: hidden;
