jQuery使用zTree外掛程式實現樹形菜單和非同步載入，jqueryztree
本文執行個體講解了jQuery使用zTree外掛程式實現樹形菜單和非同步載入，並且可以進行編輯，分享給大家供大家參考，具體內容如下
：
一、HTML代碼
<html><head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <link href="zTree/css/demo.css" rel="stylesheet" /> <link href="zTree/css/zTreeStyle/zTreeStyle.css" rel="stylesheet" /> <script src="zTree/js/jquery-1.4.4.min.js"></script> <script src="zTree/js/jquery.ztree.core-3.5.js"></script> <script src="zTree/js/jquery.ztree.excheck-3.5.js"></script> <script src="zTree/js/jquery.ztree.exedit-3.5.js"></script> <script type="text/javascript"> var setting = { async: { enable: true, url: "AjaxPage/GetAjax.aspx?z=sdfww234edfsd", autoParam: ["id"], dataFilter: filter, contentType: "application/json", type:"get" }, view: { expandSpeed: "", addHoverDom: addHoverDom, removeHoverDom: removeHoverDom, selectedMulti: false }, check: { enable: true }, edit: { enable: true }, data: { simpleData: { enable: true } }, callback: { beforeRemove: beforeRemove, beforeRename: beforeRename, } }; function filter(treeId, parentNode, childNodes) { if (!childNodes) return null; for (var i = 0, l = childNodes.length; i < l; i++) { childNodes[i].name = childNodes[i].name.replace(/\.n/g, '.'); } return childNodes; } function beforeRemove(treeId, treeNode) { var zTree = $.fn.zTree.getZTreeObj("treeDemo"); zTree.selectNode(treeNode); return confirm("確認刪除 節點 -- " + treeNode.name + " 嗎？"); } function beforeRename(treeId, treeNode, newName) { if (newName.length == 0) { alert("節點名稱不可為空."); return false; } return true; } var newCount = 1; function addHoverDom(treeId, treeNode) { var sObj = $("#" + treeNode.tId + "_span"); if (treeNode.editNameFlag || $("#addBtn_" + treeNode.tId).length > 0) return; var addStr = "<span class='button add' id='addBtn_" + treeNode.tId + "' title='add node' onfocus='this.blur();'></span>"; sObj.after(addStr); console.log("add " + "#addBtn_" + treeNode.id); var btn = $("#addBtn_" + treeNode.tId); if (btn) btn.bind("click", function () { var zTree = $.fn.zTree.getZTreeObj("treeDemo"); zTree.addNodes(treeNode, { id: (100 + newCount), pId: treeNode.id, name: "new node" + (newCount++) }); return false; }); }; function removeHoverDom(treeId, treeNode) { console.log("remove " + "#addBtn_" + treeNode.id); $("#addBtn_" + treeNode.tId).unbind().remove(); }; $(document).ready(function () { $.fn.zTree.init($("#treeDemo"), setting); }); </script></head><body> <ul id="treeDemo" class="ztree" style="width: 560px; overflow: auto;"></ul></body></html>
二、非同步請求的後台資料：
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace CssStudyWeb.AjaxPage{ public partial class GetAjax : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Request.QueryString["z"] == "sdfww234edfsd")//根據會員卡號，查詢會員卡資訊 { StringBuilder sb = new StringBuilder(); sb.Append("["); sb.Append("{\"id\":\"1\",\"name\":\"銷售單管理\",\"pId\":\"0\"},"); sb.Append("{\"id\":\"101\",\"name\":\"銷售單列表\",\"pId\":\"1\"},"); sb.Append("{\"id\":\"102\",\"name\":\"銷售單綜合查詢\",\"pId\":\"1\"},"); sb.Append("{\"id\":\"2\",\"name\":\"系統管理\",\"pId\":\"0\"},"); sb.Append("{\"id\":\"103\",\"name\":\"許可權組管理\",\"pId\":\"2\"},"); sb.Append("{\"id\":\"104\",\"name\":\"許可權菜單管理\",\"pId\":\"2\"}"); sb.Append("]"); Response.Write(sb.ToString()); } } }}
以上就是zTree外掛程式實現樹形菜單和非同步載入的全部代碼，希望對大家的學習有所協助。
