zTree使用技巧与详解
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');
}
}
