asp.net 用XML生成放便扩展的自定义树数据源为XML，因此放便扩展。废话不多说，直接上代码（因一些原因，把部分数据修改或精简了）。 XML代码：复制代码代码如下: 程序代码：复制代码代码如下: using System.Text; using System.Collections; using System.Xml; using System.Web; using System; ///

/// CreateTree 的摘要说明 ///

public class MenuTree { int index = 0;//菜单栏目ID索引 private ArrayList havePermission = new ArrayList(); private bool isVip = false; ///

/// 登录用户所拥有的权限 ///

private ArrayList HavePermissions { get { return havePermission; } set { havePermission = value; } } ///

/// 登录用户是否是VIP ///

private bool IsVip { get { return isVip; } set { isVip = value; } } ///

/// 登录用户所拥有的权限是否为VIP用户 ///

/// /// public MenuTree(ArrayList havePermission, bool isVip) { this.HavePermissions = havePermission; this.IsVip = isVip; } ///

/// 绑定树 ///

public string BindDataToTree() { System.Xml.XmlDocument document = new System.Xml.XmlDataDocument(); document.Load(HttpContext.Current.Server.MapPath("MenuData.xml")); return CreateTreeHtml(document.DocumentElement, 0); } ///

/// 创建栏目树 ///

/// xml节点 /// 树深度 private string CreateTreeHtml(System.Xml.XmlNode document, int deep) { string nodeType = "Menu";//节点的类型，来生成子节点的CSS类型 StringBuilder treeHtml = new StringBuilder(); foreach (System.Xml.XmlNode node in document.ChildNodes) { string menuId = string.Empty; string treeNodeHtml = string.Empty; string nodeName = node.Name; string showName = GetAttributesValue(node.Attributes["Name"]);//显示栏目名 string nodeId = GetAttributesValue(node.Attributes["Id"]);//栏目ID bool isExpand = GetAttributesValue(node.Attributes["IsExpand"]).ToLower().Trim() == "true" ? true : false;//是否展开 string permissions = GetAttributesValue(node.Attributes["Permissions"]);//权限字串 bool isOnlyVip = GetAttributesValue(node.Attributes["IsOnlyVip"]).ToLower().Trim() == "true" ? true : false;//是否只允许VIP访问 bool isUnVip = GetAttributesValue(node.Attributes["IsUnVip"]).ToLower().Trim() == "true" ? true : false;//是否只准非VIP访问 string eventScript = GetAttributesValue(node.Attributes["EventScript"]);//事件脚本 int chlidNodesCount = node.ChildNodes.Count;//子节点数 bool isPermissions = GetIsPermissions(permissions);//是否有权限 if (!isPermissions) { continue; //如果没有权限，不生成此节点 } if (nodeName == "Module") { if (isUnVip && IsVip) { continue;//如果为VIP会员设为不允许访问子栏目 } menuId = GetMenuId(nodeId); treeHtml.AppendFormat(""); deep = 0; nodeType = "Module"; } else { treeHtml.Append(""); treeHtml.Append(""); for (int i = 0; i < deep; i++) { if (i == deep - 1) { treeHtml.Append(""); } else { treeHtml.Append(""); } } string url = GetAttributesValue(node.Attributes["Url"]); //链接地址 string title = GetAttributesValue(node.Attributes["Title"]);//链接TITLE信息 string menuNodeId = nodeId.Trim().Length > 0 ? "id='MenuNode" + nodeId + "'" : string.Empty;//树节点ID treeHtml.Append(""); treeHtml.Append(""); treeHtml.Append("

"); if (chlidNodesCount > 0) { menuId = GetMenuId(nodeId); treeHtml.AppendFormat("", menuId, (isExpand ? "open-menu" : "close-menu")); } else { treeHtml.Append("

"); } treeHtml.Append("

"); if (url.Length > 0 || chlidNodesCount == 0) { if (!isOnlyVip || (isOnlyVip && IsVip))//栏目是否只为VIP开放 { if (url.Length > 0) { treeHtml.AppendFormat("{2}", url, title, showName, eventScript, menuNodeId); } else { treeHtml.AppendFormat("{1}", title, showName, eventScript, menuNodeId); } } else { treeHtml.AppendFormat("{2}", url, title, showName, menuNodeId); } } else { treeHtml.AppendFormat("{2}", menuId, title, showName, eventScript, menuNodeId); } treeHtml.Append("

"); } if (chlidNodesCount > 0) { treeNodeHtml = CreateTreeHtml(node, deep + 1); } if (treeNodeHtml.Length > 0) { treeHtml.AppendFormat(""); } } return treeHtml.ToString(); } ///

/// 取得栏目的ID ///

private string GetMenuId(string nodeId) { return nodeId.Length > 0 ? nodeId : Convert.ToString(++index); } ///

/// 取得节点值 ///

private string GetAttributesValue(XmlAttribute attributeValue) { return attributeValue == null ? "" : attributeValue.Value.Trim(); } ///

/// 是否有权限 ///

private bool GetIsPermissions(string permissions) { if (HavePermissions.Count == 0) { return false; } if (permissions.Length == 0) { return true; } else { string[] arrPermissions = permissions.Split(','); for (int i = 0; i < arrPermissions.Length; i++) { if (HavePermissions.Contains(arrPermissions[i].Trim())) { return true; } } return false; } } } 相关JS代码：复制代码代码如下: function DoNodes(obj,type) { var divId=obj.id+'Nodes'; var qdivObj=$("#"+divId); if(qdivObj.is(":hidden")) { qdivObj.show(); if(type=='menu') { $(obj).children("img").attr("src","Images/open-menu.gif"); } else { qdivObj.siblings(".Menus:visible").hide(); } } else { qdivObj.hide(); if(type=='menu') { $(obj).children("img").attr("src","Images/close-menu.gif"); } } } function DoAClick(id) { $("#"+id).click(); } function AlertVip() { alert("非常抱歉,此模块只对VIP会员开放!");return false; } 最后效果此代码我觉得易放便扩展，只要稍改动一下代码就能使用在自己的项目中。
