如果不用从后台生成前台htm静态树,则树的速度有点慢,所以我把梅花树改了下:

梅花树的资料:开发文档: http://www.meizz.com/Web/Article.asp?id=436
控件下载: http://www.meizz.com/Web/Download/MzTreeView10.rar
应用示例: http://www.meizz.com/Web/Demo/MzTreeView10.htm

首先模板treetemplate.htm文件如下:

<HTML>
<HEAD>
<title>tree</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<script language="JavaScript" src="MzTreeView10.js"></script>
<link href="menutree/menu.css" type="text/css" rel="stylesheet">
<style> A.MzTreeview { PADDING-LEFT: 3px; FONT-SIZE: 12px } </style>
</HEAD>
<body leftmargin="0" topmargin="2">
<SCRIPT LANGUAGE="JavaScript">
window.tree = new MzTreeView("tree");
tree.setIconPath("menutree/"); //可用相对路径
abcdefg
document.write(tree.toString()); //亦可用 obj.innerHTML = tree.toString();
//-->
</SCRIPT>
</body>
</HTML>

好了,下面是页面managertre.aspx的代码:

<%@ Page language="c#" Codebehind="managertree.aspx.cs" AutoEventWireup="false" Inherits="hualong.manager" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<script language="javascript">
<!--
function ShowJie()
{
TianJia.style.display = "";
}
function window.onload()
{
if(arr=document.cookie.match(/scrollTop=([^;]+)(;|$)/))
document.body.scrollTop=parseInt(arr[1]);
}
function window.onbeforeunload(){
document.cookie="scrollTop="+document.body.scrollTop;
}
//-->
</script>
</HEAD>
