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.

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") @ResponseBody public 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; }
