在同一個頁面如果有兩個tree，而且想要兩個tree的點選事件區別開來，需要設定獨立的一套setting和回撥函式，如下：

//第一棵樹

var setting = {
    isSimpleData : true,              //資料是否採用簡單 Array 格式，預設false
    treeNodeKey : "id",               //在isSimpleData格式下，當前節點id屬性
    treeNodeParentKey : "pId",        //在isSimpleData格式下，當前節點的父節點id屬性
    view: {
        
 
showIcon: false,
        addHoverDom: false,
        removeHoverDom: false,
        selectedMulti: false
    },
    data: {
        simpleData: {
            enable: true
        }
    },
    callback: {
        onClick: zTreeOnClickcar
    }
};
/*var zNodes =[
    {id:1, pId:0, name:"奧迪"},
    {id:101, pId:1, name:"一汽-大眾"},
 
    {id:102, pId:101, name:"邁騰"},
    {id:103, pId:101, name:"奧迪A4"},
    {id:2, pId:0, name:"巴博斯"},
    {id:201, pId:2, name:"巴博斯1"},
    {id:202, pId:2, name:"巴博斯2"},
    {id:3, pId:0, name:"寶馬"},
    {id:301, pId:3, name:"寶馬1"},
    {id:302, pId:3, name:"寶馬2"},
    {id:4, pId:0, name:"長城"},
    {id:401, pId:4, name:"長城1"},
 
    {id:402, pId:4, name:"長城2"},
    {id:5, pId:0, name:"大眾"},
    {id:501, pId:5, name:"大眾1"},
    {id:502, pId:5, name:"大眾2"}

var zNodes;
$(document).ready(function(){
    $.ajax({
        dataType : "json",
        url: "js/data/carztree.json",//請求的路徑
        success:function(data){ //請求成功後處理函式。
            zNodes = data.data;   //把後臺封裝好的簡單Json格式賦給treeNodes
        },
        error: function () {//請求失敗處理函式
            alert('請求失敗');
        }
    });
    $.fn.zTree.init($("#carztree"), setting, zNodes);
});

function zTreeOnClickcar(event, treeId, treeNode) {
   // alert(treeNode.tId + ", " + treeNode.name); //顯示tree的id和名字
    if(treeNode.tId == "carztree_3"){
        gotoUrl(105);
    }
};

//第二棵樹
