MVC中ztree异步加载

var setting = {
        async: {
            enable: true,
            url: "*****/LoadChild",
            autoParam: ["id"],
            dataFilter: filter
        }
    };

    function filter(treeId, parentNode, childNodes) {
        if (!childNodes) return null;
        for (var i = 0, l = childNodes.length; i < l; i++) {
            childNodes[i].name = childNodes[i].name.replace(/.n/g, '.');
        }
        return childNodes;
    }

　　后台

public ActionResult LoadChild(string id)
        {
            List<Sys_User_List> listUser = _bll.GetList(id, false);//得到子节点
            var list = listUser.Select(user =>
            {
                var treeNode = new ZTreeJsonEntityForGrant
                {
                    id = user.Id.ToString(),
                    pId = id,

            }).ToList();

            return new ConfigurableJsonResult<ZTreeJsonEntityForGrant>(list);
