zTree--Jquery 树插件，是在后台管理页面中常使用到的插件。

使用效果图：

核心代码：

zTree配置：
var setting = {data:{simpleData:{enable:true,idKey:"id",pIdKey:"pId",rootPId:'0'}},async: {  enable: true,url:"${ctx}/ownerinformation/lifetouchOwnerInformation/houseTreeData",contentType:"application/x-www-form-urlencoded",autoParam:["officeId", "officeName", "floorId", "unitNumberId", "roomNumberId"],//otherParam:{"otherParam":"zTreeAsyncTest"},//提交的其他参数,json的形式  dataType:"json",type:"post",dataFilter: null},callback:{onClick:function(event, treeId, treeNode){refreshWhice='';var officeId = treeNode.officeId === undefined ? '' :treeNode.officeId;var floorId = treeNode.floorId === undefined ? '' :treeNode.floorId;var unitNumberId = treeNode.unitNumberId === undefined ? '' :treeNode.unitNumberId;var roomNumberId = treeNode.roomNumberId === undefined ? '' :treeNode.roomNumberId;var ownerId = treeNode.ownerId === undefined ? '' :treeNode.ownerId;if(treeNode.ownerId) {$('#officeContent').attr("src","${ctx}/ownerinformation/lifetouchOwnerInformation/details?houseType=1&id="+treeNode.ownerId);} else {$('#officeContent').attr("src","${ctx}/ownerinformation/lifetouchOwnerInformation/list?houseType=1&houseInformation.office.id="+officeId+"&houseInformation.floor="+floorId+"&houseInformation.unitNumber="+unitNumberId+"&houseInformation.roomNumber="+roomNumberId+"&id="+ownerId);}},onRightClick: OnRightClick}};zTree初始化：
function refreshTree(){$.getJSON("${ctx}/ownerinformation/lifetouchOwnerInformation/ownerTreeData",function(data){$.fn.zTree.init($("#ztree"), setting, data);zTreeMy = $.fn.zTree.getZTreeObj("ztree");});
}
refreshTree();zTree刷新当前选中节点或者刷新当前选中节点的父节点：
//刷新节点
function refreshNode() {type = "refresh",  silent = false,  nodes = zTreeMy.getSelectedNodes(); if(nodes.length>0) {if(refreshWhice=='refreshNode') {zTreeMy.reAsyncChildNodes(nodes[0], type, silent);var fiterNode = refreshFiter();if(fiterNode != null) {zTreeMy.selectNode(fiterNode);  zTreeMy.reAsyncChildNodes(fiterNode, type, silent);}} else if(refreshWhice=='refreshParentNode') {var parentNode = zTreeMy.getNodeByTId(nodes[0].parentTId);  zTreeMy.selectNode(parentNode);  zTreeMy.reAsyncChildNodes(parentNode, type, silent);var fiterNode = refreshFiter();if(fiterNode != null) {zTreeMy.selectNode(fiterNode);  zTreeMy.reAsyncChildNodes(fiterNode, type, silent);}}}
}zTree根据自定义规则搜索节点：
var officeId, floorId, unitNumberId, roomNumberId;//根据自定义规则搜索节点function refreshFiter() {var fiterNode = zTreeMy.getNodesByFilter(function (node) { return (node.officeId == officeId && node.floorId == floorId &&node.unitNumberId == unitNumberId && node.roomNumberId == roomNumberId)}, true);if(fiterNode==null) {fiterNode = zTreeMy.getNodesByFilter(function (node) { return (node.officeId == officeId && node.floorId == floorId &&node.unitNumberId == unitNumberId)}, true);if(fiterNode==null) {fiterNode = zTreeMy.getNodesByFilter(function (node) { return (node.officeId == officeId && node.floorId == floorId)}, true);if(fiterNode==null) {fiterNode = zTreeMy.getNodesByFilter(function (node) { return (node.officeId == officeId)}, true);}}}return fiterNode;}zTree右键事件：
function OnRightClick(event, treeId, treeNode) {if (!treeNode && event.target.tagName.toLowerCase() != "button" && $(event.target).parents("a").length == 0) {zTreeMy.cancelSelectedNode();showRMenu("root", event.clientX, event.clientY);} else if (treeNode && !treeNode.noR) {if(treeNode.level>0) {$("#m_matching").hide();$("#m_add").show();$("#m_update").hide();$("#m_del").hide();if(treeNode.ownerId) {if(treeNode.status=='1') {$("#m_matching").show();}$("#m_add").hide();$("#m_update").show();$("#m_del").show();} else if(treeNode.roomNumberId) {$("#m_add").text("增加住户");$("#m_update").show();$("#m_del").show();} else if(treeNode.unitNumberId) {$("#m_add").text("增加房间");} else if(treeNode.floorId) {$("#m_add").text("增加楼层");} else if(treeNode.officeId) {$("#m_add").text("增加栋数");}zTreeMy.selectNode(treeNode);showRMenu("node", event.clientX, event.clientY);}}}zTree增加子节点：
function addTreeNode() {refreshWhice='refreshNode';hideRMenu();var treeNode = zTreeMy.getSelectedNodes()[0];if(treeNode.roomNumberId) {$('#officeContent').attr("src","${ctx}/ownerinformation/lifetouchOwnerInformation/form?houseType=1&houseInformation.office.id="+treeNode.officeId+"&houseInformation.office.name="+treeNode.officeName+"&houseInformation.floor="+treeNode.floorId+"&houseInformation.unitNumber="+treeNode.unitNumberId+"&houseInformation.roomNumber="+treeNode.roomNumberId);} else if(treeNode.unitNumberId) {$('#officeContent').attr("src","${ctx}/houseinformation/lifetouchHouseInformation/form?houseType=1&office.id="+treeNode.officeId+"&office.name="+treeNode.officeName+"&floor="+treeNode.floorId+"&unitNumber="+treeNode.unitNumberId);} else if(treeNode.floorId) {$('#officeContent').attr("src","${ctx}/houseinformation/lifetouchHouseInformation/form?houseType=1&office.id="+treeNode.officeId+"&office.name="+treeNode.officeName+"&floor="+treeNode.floorId);} else if(treeNode.officeId) {$('#officeContent').attr("src","${ctx}/houseinformation/lifetouchHouseInformation/form?houseType=1&office.id="+treeNode.officeId+"&office.name="+treeNode.officeName);}}zTree修改节点：
function updateTreeNode() {refreshWhice='refreshParentNode';hideRMenu();var treeNode = zTreeMy.getSelectedNodes()[0];if(treeNode.ownerId) {$('#officeContent').attr("src","${ctx}/ownerinformation/lifetouchOwnerInformation/form?houseType=1&id="+treeNode.ownerId);} else if(treeNode.roomNumberId) {$('#officeContent').attr("src","${ctx}/houseinformation/lifetouchHouseInformation/form?houseType=1&id="+treeNode.houseId);}}zTree删除节点：
function removeTreeNode() {refreshWhice='refreshParentNode';hideRMenu();var treeNode = zTreeMy.getSelectedNodes()[0];if(treeNode.ownerId) {top.$.jBox.confirm("确认要删除该住户管理信息吗？","系统提示",function(v,h,f){if(v=="ok"){$('#officeContent').attr("src","${ctx}/ownerinformation/lifetouchOwnerInformation/delete?houseType=1&id="+treeNode.ownerId);}},{buttonsFocus:1});top.$('.jbox-body .jbox-icon').css('top','55px');} else if(treeNode.roomNumberId) {top.$.jBox.confirm("确认要删除该房屋信息吗？","系统提示",function(v,h,f){if(v=="ok"){$('#officeContent').attr("src","${ctx}/houseinformation/lifetouchHouseInformation/delete?houseType=1&id="+treeNode.houseId);}},{buttonsFocus:1});top.$('.jbox-body .jbox-icon').css('top','55px');}}整体内容：
