我得到一个错误当我添加一个MenuList进入菜单。 计算机科学,因为我的MySql表中没有MenuList那里。 但我无法添加MenuList菜单。 cs,这意味着我不能创建一个动态菜单,任何人在这种情况下有解决方案吗? 请帮助我,我被困在这里大约一个星期。

MySql表:

CREATE TABLE Menusss( MenuId int not null auto_increment, MenuName varchar(250), ParentId int, ActiveNo int);

Menus.cs:

public class Menus{ [Key] public int MenuId { get; set; } public string MenuName { get; set; } public int? ParentId { get; set; } public int ActiveNo { get; set; } public List MenuList { get; set; } = new List();}

MenusController.cs:

[HttpGet]public ActionResult GetMenus(){ List menuList = new List(); foreach (Menus m in _context.menus.ToList()) { menuList.Add(m); } List menuTree = GetMenuTree(menuList, null); return menuTree;}private List GetMenuTree(List list, int? parentId){ return list.Where(x => x.ParentId == parentId).Select(x => new Menus() { MenuId = x.MenuId, MenuName = x.MenuName, ParentId = x.ParentId, ActiveNo = x.ActiveNo, MenuList = GetMenuTree(list, x.MenuId) }).ToList();}

MY.js:

$(document).ready(function () { $.ajax({ url: '', method: 'get', dataType: 'json', success: function (data) { buildMenu($('#menu'), data); $('#menu').menu(); }}); function buildMenu(parent, items) { $.each(items, function () { var li = $("" + this.MenuName + ""); if (this.ActiveNo == 0) { li.addClass('ui-state-disabled'); } li.appendTo(parent); if (this.MenuList && this.MenuList.length > 0) { var ul = $(""); ul.appentTo(li); buildMenu(ul, this.MenuList); } }); }});
