zTree是一款挺好用的树形插件，中文文档齐全，demo丰富。
官方网站是 http://www.treejs.cn/v3/main.php#_zTreeInfo
源码网站 https://github.com/zTree/zTree_v3
使用方法：
1、引入jquery库

|
|
2、引入css和js
|
1
|
<link rel="stylesheet" href="css/zTreeStyle/zTreeStyle.css" type="text/css"> |
|
1
|
<script type="text/javascript" src="js/jquery.ztree.core.js"></script> |
4、初始化树
设置一个展示tree的DOM节点。（如果对DOM不了解，建议先学习HTML和JavaScript）
|
1
|
<ul id="treeDemo" class="ztree"></ul> |
其中class要指定为ztree，这样才能显示为树形。
实例化ztree

var setting = { };var zNodes =[ { name:"父节点1 - 展开", open:true, children: [ { name:"父节点11 - 折叠", children: [ { name:"叶子节点111"}, { name:"叶子节点112"}, { name:"叶子节点113"}, { name:"叶子节点114"} ]}, { name:"父节点12 - 折叠", children: [ { name:"叶子节点121"}, { name:"叶子节点122"}, { name:"叶子节点123"}, { name:"叶子节点124"} ]}, { name:"父节点13 - 没有子节点", isParent:true} ]}, { name:"父节点2 - 折叠", children: [ { name:"父节点21 - 展开", open:true, children: [ { name:"叶子节点211"}, { name:"叶子节点212"}, { name:"叶子节点213"}, { name:"叶子节点214"} ]}, { name:"父节点22 - 折叠", children: [ { name:"叶子节点221"}, { name:"叶子节点222"}, { name:"叶子节点223"}, { name:"叶子节点224"} ]}, { name:"父节点23 - 折叠", children: [ { name:"叶子节点231"}, { name:"叶子节点232"}, { name:"叶子节点233"}, { name:"叶子节点234"} ]} ]}, { name:"父节点3 - 没有子节点", isParent:true}];$(document).ready(function(){ $.fn.zTree.init($("#treeDemo"), setting, zNodes);}); |
$.fn.zTree.init()函数实例化树，指定要渲染的DOM，ztree配置，及节点。
节点数据是JSON数据，符合当前软件开发的数据交换。
