jQuery zTree树插件简单使用教程

<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"},

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
