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.

静态zTree开发流程
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>

异步zTree加载
前面的配置相同,在此不再阐述.主要是js不同.
异步JS

var setting = {//可勾选check: {enable: true},data : {simpleData : {enable : true}}};function initTree（）{var payFreq = $（"#payFreq"）.val（）;var fyType = $（"#fyType"）.val（）;var setHzType = $（"#setHzType"）.val（）;$.ajax（{url : "/demo/initTree",data : {payFreq:payFreq,fyType:fyType,setHzType:setHzType},success: function（object）{var nodes = "";//拼接simple格式的json字符串$.each（object.data, function（i,item） { nodes+="{id:""+item.id+"", pId:""+item.pid+"", name:""+item.name+"", isParent:""+item.isParent+""},";}）;var zNodes = "["+nodes+"]";var json = eval（"（" + zNodes + "）"）; //console.log（json）;zTreeInit（json）;}}）;}/* 初始化树 */function zTreeInit（json） {$.fn.zTree.init（$（"#treeDemo"）, setting, json）;var zTree = $.fn.zTree.getZTreeObj（"treeDemo"）;//全部展开zTree.expandAll（true）;//Y代表勾选时,N代表取消勾选 p代表父节点,s代表字节点setting.check.chkboxType = { "Y" : "ps", "N" : "ps" };}

java代码
Controller层

@RequestMapping（"initTree"）@ResponseBodypublic DataMessage initTree（String setHzType,String payFreq,String fyType）{params.put（"setHzType", setHzType）;params.put（"fyType", fyType）;params.put（"fkmattr_xt", fkmattr_xt）;//获取treeinfo列表List<TreeInfo> treeInfos = feeTransferService.initTree（params）;return DataMessage.successData（treeInfos）;}

tree实体类

public class TreeInfo {private String id;private String pid;private String name;private String isParent;}

说明
更多实例可以参看zTree中文文档
或参见zTree GitHub 里面更多的示例和说明。
