bootstrap jQuery Ztree异步载入数据,check选择&可加入、改动、删除节点
效果图:
一、下载zTree插件 地址:http://www.ztree.me
二、html代码
<link href="../Scripts/zTree/css/zTreeStyle/zTreeStyle.css" rel="stylesheet" /> <script src="../Scripts/zTree/js/jquery-1.4.4.min.js"></script> <script src="../Scripts/zTree/js/jquery.ztree.core-3.5.js"></script> <script src="../Scripts/zTree/js/jquery.ztree.excheck-3.5.js"></script> <script src="../Scripts/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"], contentType: "application/json", type: "get", dataFilter: filter }, 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); alert(treeNode.Action);//哈哈 出来了 return confirm("确认删除 节点 -- " + treeNode.name + " 吗?"); } function beforeRename(treeId, treeNode, newName) { if (newName.length == 0) { alert("节点名称不能为空!"); 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); var btn = $("#addBtn_" + treeNode.tId); if (btn) btn.bind("click", function () { var zTree = $.fn.zTree.getZTreeObj("treeDemo"); zTree.addNodes(treeNode, { id: (treeNode.id + newCount), parentid: treeNode.id, name: "new node" + (newCount++) }); return false; }); }; function removeHoverDom(treeId, treeNode) { $("#addBtn_" + treeNode.tId).unbind().remove(); }; $(document).ready(function () { $.fn.zTree.init($("#treeDemo"), setting); }); </script> <div class="row"> <div class="col-lg-12 col-sm-12 col-xs-12 col-xxs-12"> <div class="panel panel-default"> <div class="panel-heading"> <h2>权限菜单管理</h2> <div class="panel-actions"> <a href="MenuManagement.aspx#" class="btn-minimize"><i class="fa fa-chevron-up"></i></a> <a href="MenuManagement.aspx#" class="btn-close"><i class="fa fa-times"></i></a> </div> </div> <div class="panel-body"> <div class="row"> <div class="col-md-12"> <ul id="treeDemo" class="ztree"></ul> </div> </div> </div> </div> </div> </div>
三、zTreeStyle.css改动加入节点button的图片样式
.ztree li span.button.add { margin-left: 2px; margin-right: -1px; background-position: -144px 0; vertical-align: top; }
四、后台代码:
protected void Page_Load(object sender, EventArgs e) { if (Request.QueryString["z"] == "sdfww234edfsd") { StringBuilder sb = new StringBuilder(); sb.Append("["); sb.Append("{\"id\":\"1\",\"name\":\"销售单管理\",\"pId\":\"0\",\"Action\":\"list\"},"); sb.Append("{\"id\":\"2\",\"name\":\"销售单列表\",\"pId\":\"1\",\"Action\":\"list\"},"); sb.Append("]"); Response.Write(sb.ToString()); } }
说明:据我測试看来,id、name、pId为三个必需的字段,pId可看做parentID,open=true 则会展开次节点。
