jQuery在ASP.NET Core 2.1中返回“未定义”值

Question

I'm trying to create a dynamic menu, when I run the Web API , I can get correct JSON string, but when I run Razor Pages , I only get the "Undefined" . Anythings wrong in my JQuery ?

Thanks in advance.

$(document).ready(function () {
    getData();
    getTopMenu();
    SideMenu();
});

function SideMenu() {
    $.ajax({
        type: 'GET',
        url: "https://localhost:44328/api/menus",
        success: function (data) {
            buildMenu($('#menu'), data);
            $('#menu').menu();
        }
    });

    function buildMenu(parent, items) {
        $.each(items, function () {
            var li = $("<li>" + this.MenuName + "</li>");
            if (this.ActiveNo == 0) {
                li.addClass('ui-state-disabled');
            }

            li.appendTo(parent);

            if (this.MenuList && this.MenuList.length > 0) {
                var ul = $("<ul></ul>");
                ul.appentTo(li);
                buildMenu(ul, this.MenuList);
            }
        });
    }
}

this.MenuName <-这是问题，因为它没有遵循JSON字符串，应该是this.menuName
