定义了dataFilter ，但是ajaxDataFilter函数没有执行，求助！！
var setting = {
data: {
simpleData: {
enable: true,
idKey: "code",
pIdKey: "pCode",
rootPId: "systemRoot"
},
key:{
name:"name"
}
},
async:{
autoParam:["name","code"],
enable:true,
url:'/api/menu/list',
type:'get',
dataFilter: ajaxDataFilter
},
view: {
selectedMulti: false
},
callback: {
beforeAsync: zTreeBeforeAsync,
onAsyncSuccess:zTreeOnAsyncSuccess,
onClick: zTreeOnClick
}
};
$.fn.zTree.init(deptTree,setting,null);

请 仔细调试检查。。。Demo 中也用到了 dataFilter的，可以对照
