本文介绍如何利用layui框架和zTree插件创建动态树形选择器，包括引入必要的css和JS文件，配置JQuery和layui，以及渲染树形结构并设置点击回调等交互功能。

引入基础css和JS脚本

<link rel="stylesheet" href="../../../js/layuiadmin/layui/css/layui.css" media="all">
<link rel="stylesheet" href="../../../js/layuiadmin/style/admin.css" media="all">

<script src="../../../js/jquery/jquery-1.11.3.min.js"></script>
<script src="../../../js/layuiadmin/layui/layui.js"></script>

正式HTML代码

 <input type="text" id="tree" lay-filter="tree" class="layui-input">

JQuery

<script>
layui.config({
		base: '../../../js/layuiadmin/layui/lay/modules/treeSelect/'//引入treeselect.js脚本
	}).extend({
		treeGrid:'treeSelect'
	}).use(['jquery','treeSelect','layer','form'], function(){
		var $=layui.jquery;
		layer=layui.layer;

		var treeSelect= layui.treeSelect;

		treeSelect.render({
			// 选择器
			elem: '#tree',
			// 数据
			data: '../../../js/ztree/data3.json',//json数据
			// 异步加载方式：get/post，默认get
			type: 'get',
			// 占位符
			placeholder: '修改默认提示信息',
			// 是否开启搜索功能：true/false，默认false
			search: true,
			// 点击回调
			click: function(d){
				console.log(d);
			},
			// 加载完成后的回调函数
			success: function (d) {
				console.log(d);
//                选中节点，根据id筛选
//                treeSelect.checkNode('tree', 3);

//                获取zTree对象，可以调用zTree方法
//                var treeObj = treeSelect.zTree('tree');
//                console.log(treeObj);

//                刷新树结构
//                treeSelect.refresh();
			}
		});
	});
</script>
