ztree 异步加载子节点

var zTreeObj={

};
var zTreeObj2={

};
var type ='${type}';
var setting = {
async:{
enable:true,
dataFilter:null,
url:"wslms/cate/getChildrenNodes",
autoParam:["id","name"],
contentType:'application/x-www-form-urlencoded',
dataType:'json',
otherParam:[],
type:'post'
},
data:{
simpleData:{
enable:false,
idKey:'id',
pIdKey:'pId',
rootPid:'0'
}
},
/* callback:{
onDblClick:_rightClick
}, /
view:{
dblClickExpand:false
}
};
/ function _rightClick(event,treeId,treeNode){
var url ='${ctx}/enterpriseInfo/schoolTreeNavi2';
var param ={entId:treeNode.id};
$.post(url,param,function(data){
var result = data.page;
var html = '';
if(data==null||result.length==0){
html='

暂无任何联系人信息';
}
for(var i=0;i html+=''+result[i].name+''+result[i].sex+''+result[i].provincal
+''+result[i].city+''+result[i].mobile+''
}
$("#entContactList").html(html);
$("#industryTag").html(data.enter.professionalType);
});
} */
var zNodes = eval('${list}');
$(document).ready(function(){
zTreeObj = $.fn.zTree.init($("#treeDemo"), setting, zNodes);
zTreeObj.selectNode(zTreeObj.getNodeByParam("id",'${nodeId}',null));
});
为什么这个url:"wslms/cate/getChildrenNodes",不能触发，如何获取子节点
