jQuery zTree树插件简单使用教程

前言

zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。
支持静态 和 Ajax 异步加载节点数据.
在开发中我们常需要用到树状的展示.

引入资源

<link rel="stylesheet" href="../../../css/zTreeStyle/zTreeStyle.css" type="text/css"><script type="text/javascript" src="../../../js/jquery-1.4.4.min.js"></script><script type="text/javascript" src="../../../js/jquery.ztree.core.js"></script>

html元素

<div> <ul id="treeDemo" class="ztree"></ul></div>

JS方式一-简单json数据格式

<SCRIPT type="text/javascript">  <!--  var setting = {   data: {    simpleData: {     enable: true    }   }  };  var zNodes =[   { id:1, pId:0, name:"父节点1 - 展开", open:true},   { id:11, pId:1, name:"父节点11 - 折叠"},   { id:111, pId:11, name:"叶子节点111"},   { id:112, pId:11, name:"叶子节点112"},   { id:113, pId:11, name:"叶子节点113"},   { id:114, pId:11, name:"叶子节点114"},   { id:12, pId:1, name:"父节点12 - 折叠"},   { id:121, pId:12, name:"叶子节点121"},   { id:122, pId:12, name:"叶子节点122"},   { id:123, pId:12, name:"叶子节点123"},   { id:124, pId:12, name:"叶子节点124"},   { id:13, pId:1, name:"父节点13 - 没有子节点", isParent:true},   { id:2, pId:0, name:"父节点2 - 折叠"},   { id:21, pId:2, name:"父节点21 - 展开", open:true},   { id:211, pId:21, name:"叶子节点211"},   { id:212, pId:21, name:"叶子节点212"},   { id:213, pId:21, name:"叶子节点213"},   { id:214, pId:21, name:"叶子节点214"},   { id:22, pId:2, name:"父节点22 - 折叠"},   { id:221, pId:22, name:"叶子节点221"},   { id:222, pId:22, name:"叶子节点222"},   { id:223, pId:22, name:"叶子节点223"},   { id:224, pId:22, name:"叶子节点224"},   { id:23, pId:2, name:"父节点23 - 折叠"},   { id:231, pId:23, name:"叶子节点231"},   { id:232, pId:23, name:"叶子节点232"},   { id:233, pId:23, name:"叶子节点233"},   { id:234, pId:23, name:"叶子节点234"},   { id:3, pId:0, name:"父节点3 - 没有子节点", isParent:true}  ];  $(document).ready(function(){   $.fn.zTree.init($("#treeDemo"), setting, zNodes);  });  //--> </SCRIPT>

JS方式二-标准json数据格式

<SCRIPT type="text/javascript">  <!--  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);  });  //--> </SCRIPT>
