 更新時(shí)間：2017年01月10日 14:17:28   作者：你在橋上看風(fēng)景丶  
這篇文章主要為大家詳細(xì)介紹了jQuery zTree樹(shù)插件簡(jiǎn)單使用教程，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

前言

zTree 是一個(gè)依靠 jQuery 實(shí)現(xiàn)的多功能 “樹(shù)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(diǎn)。
支持靜態(tài) 和 Ajax 異步加載節(jié)點(diǎn)數(shù)據(jù).
在開(kāi)發(fā)中我們常需要用到樹(shù)狀的展示.

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(shù) */
 function zTreeInit(json) {
  $.fn.zTree.init($("#treeDemo"), setting, json);
  var zTree = $.fn.zTree.getZTreeObj("treeDemo");
  //全部展開(kāi)
  zTree.expandAll(true);
  //Y代表勾選時(shí),N代表取消勾選 p代表父節(jié)點(diǎn),s代表字節(jié)點(diǎn)
  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(shí)體類

public class TreeInfo {

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

說(shuō)明

更多實(shí)例可以參看zTree中文文檔
或參見(jiàn)zTree GitHub 里面更多的示例和說(shuō)明。
