這篇文章主要為大家詳細介紹了jQuery zTree樹插件簡單使用教程，具有一定的參考價值，感興趣的小伙伴們可以參考一下

前言

zTree 是一個依靠 jQuery 實現(xiàn)的多功能 “樹插件”。優(yōu)異的性能、靈活的配置、多種功能的組合是 zTree 最大優(yōu)點。
支持靜態(tài) 和 Ajax 異步加載節(jié)點數(shù)據(jù).
在開發(fā)中我們常需要用到樹狀的展示.

靜態(tài)zTree開發(fā)流程

引入資源

<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-簡單json數(shù)據(jù)格式

<SCRIPT type="text/javascript">
  <!--
  var setting = {
   data: {
    simpleData: {
     enable: true
    }
   }
  };

  var zNodes =[
   { id:1, pId:0, name:"父節(jié)點1 - 展開", open:true},
   { id:11, pId:1, name:"父節(jié)點11 - 折疊"},
   { id:111, pId:11, name:"葉子節(jié)點111"},
   { id:112, pId:11, name:"葉子節(jié)點112"},
   { id:113, pId:11, name:"葉子節(jié)點113"},
   { id:114, pId:11, name:"葉子節(jié)點114"},
   { id:12, pId:1, name:"父節(jié)點12 - 折疊"},
   { id:121, pId:12, name:"葉子節(jié)點121"},
   { id:122, pId:12, name:"葉子節(jié)點122"},
   { id:123, pId:12, name:"葉子節(jié)點123"},
   { id:124, pId:12, name:"葉子節(jié)點124"},
   { id:13, pId:1, name:"父節(jié)點13 - 沒有子節(jié)點", isParent:true},
   { id:2, pId:0, name:"父節(jié)點2 - 折疊"},
   { id:21, pId:2, name:"父節(jié)點21 - 展開", open:true},
   { id:211, pId:21, name:"葉子節(jié)點211"},
   { id:212, pId:21, name:"葉子節(jié)點212"},
   { id:213, pId:21, name:"葉子節(jié)點213"},
   { id:214, pId:21, name:"葉子節(jié)點214"},
   { id:22, pId:2, name:"父節(jié)點22 - 折疊"},
   { id:221, pId:22, name:"葉子節(jié)點221"},
   { id:222, pId:22, name:"葉子節(jié)點222"},
   { id:223, pId:22, name:"葉子節(jié)點223"},
   { id:224, pId:22, name:"葉子節(jié)點224"},
   { id:23, pId:2, name:"父節(jié)點23 - 折疊"},
   { id:231, pId:23, name:"葉子節(jié)點231"},
   { id:232, pId:23, name:"葉子節(jié)點232"},
   { id:233, pId:23, name:"葉子節(jié)點233"},
   { id:234, pId:23, name:"葉子節(jié)點234"},
   { id:3, pId:0, name:"父節(jié)點3 - 沒有子節(jié)點", isParent:true}
  ];

  $(document).ready(function(){
   $.fn.zTree.init($("#treeDemo"), setting, zNodes);
  });
  //-->
 </SCRIPT>

JS方式二-標準json數(shù)據(jù)格式

<SCRIPT type="text/javascript">
  <!--
  var setting = { };

  var zNodes =[
   { name:"父節(jié)點1 - 展開", open:true,
    children: [
     { name:"父節(jié)點11 - 折疊",
      children: [
       { name:"葉子節(jié)點111"},
       { name:"葉子節(jié)點112"},
       { name:"葉子節(jié)點113"},
       { name:"葉子節(jié)點114"}
      ]},
     { name:"父節(jié)點12 - 折疊",
      children: [
       { name:"葉子節(jié)點121"},
       { name:"葉子節(jié)點122"},
       { name:"葉子節(jié)點123"},
       { name:"葉子節(jié)點124"}
      ]},
     { name:"父節(jié)點13 - 沒有子節(jié)點", isParent:true}
    ]},
   { name:"父節(jié)點2 - 折疊",
    children: [
     { name:"父節(jié)點21 - 展開", open:true,
      children: [
       { name:"葉子節(jié)點211"},
       { name:"葉子節(jié)點212"},
       { name:"葉子節(jié)點213"},
       { name:"葉子節(jié)點214"}
      ]},
     { name:"父節(jié)點22 - 折疊",
      children: [
       { name:"葉子節(jié)點221"},
       { name:"葉子節(jié)點222"},
       { name:"葉子節(jié)點223"},
       { name:"葉子節(jié)點224"}
      ]},
     { name:"父節(jié)點23 - 折疊",
      children: [
       { name:"葉子節(jié)點231"},
       { name:"葉子節(jié)點232"},
       { name:"葉子節(jié)點233"},
       { name:"葉子節(jié)點234"}
      ]}
    ]},
   { name:"父節(jié)點3 - 沒有子節(jié)點", isParent:true}

  ];

  $(document).ready(function(){
   $.fn.zTree.init($("#treeDemo"), setting, zNodes);
  });
  //-->
 </SCRIPT>

異步zTree加載

前面的配置相同,在此不再闡述.主要是js不同.

異步JS

var setting = {
 //可勾選
 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);
   }
  });

 }
 /* 初始化樹 */
 function zTreeInit(json) {
  $.fn.zTree.init($("#treeDemo"), setting, json);
  var zTree = $.fn.zTree.getZTreeObj("treeDemo");
  //全部展開
  zTree.expandAll(true);
  //Y代表勾選時,N代表取消勾選 p代表父節(jié)點,s代表字節(jié)點
  setting.check.chkboxType = { "Y" : "ps", "N" : "ps" };

 }

java代碼

Controller層

@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);
  //獲取treeinfo列表
  List<TreeInfo> treeInfos = feeTransferService.initTree(params);
  return DataMessage.successData(treeInfos);
 }

tree實體類

public class TreeInfo {

 private String id;
 private String pid;
 private String name;
 private String isParent;
 }

或參見zTree GitHub 里面更多的示例和說明。
