Third, the dynamic loading menu

By abp (net core) + easyui + efcore implement Warehouse Management System - menu - on (xvi) of this article, we have learned about the properties and methods of the class and the class of ABP in the relevant menu, it took us by example to achieve a dynamic load function menu. The menu is dynamic we abp (net core) + easyui + efcore implement warehouse management system - the domain layer created entity (c) to abp (net core) + easyui + efcore implement Warehouse Management System - presentation layer implementation of CRUD CRUD view (VIII) added function module.

1. In Visual Studio 2017's "Solution Explorer", right-click "ABP.TPLMS.Mvc.Web" project "Startup" folder, the pop-up menu, select "Add">> "class." Name the class DaynaicAddMenu, then select "Add." As shown below.

2. Open DaynaicAddMenu.cs file we just created in Visual Studio editor in 2017, write the following code.

using Abp.Application.Navigation;
using Abp.Localization;
using ABP.TPLMS.Entitys;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
 

namespace ABP.TPLMS.Web.Startup
{
    public class DynamicAddMenu
    {
         Modules.IModuleAppService _moduleAppService;
        public DynamicAddMenu(Modules.IModuleAppService moduleApp)

        { _moduleAppService = moduleApp; }
        public  MenuItemDefinition AddMenus()
        {
            #region 动态菜单
           var modules= _moduleAppService.GetAll();
            var project = new MenuItemDefinition(
                    "Business",
                    L("Business"),                  

                    icon: "menu",
                    order: 5
                    );    

            var list = modules.ToList();
            FillMenu(project, 0, list);
            return project;
            #endregion
        }

        // 递归算法
        private  void FillMenu(MenuItemDefinition menu, int ParentId, List<Module> modules)
        {
            List<Module> drs = modules.Where(x=>x.ParentId==ParentId).ToList();
            if (drs == null || drs.Count <=0)
            {
                return;
            }
            else
            {
                for (int i = 0; i < drs.Count; i++)
                {
                    Module dr = drs[i];
                    MenuItemDefinition nodeName = new MenuItemDefinition(
                       dr.Name,
                       L(dr.DisplayName),
                       url: dr.Url,
                       icon: "business",
                       requiredPermissionName: dr.RequiredPermissionName,
                       customData: i
                   );
                    menu.AddItem(nodeName);
                    FillMenu(nodeName, dr.Id, modules);
                }
            }
        }

        private static ILocalizableString L(string name)
        {
            return new LocalizableString(name, TPLMSConsts.LocalizationSourceName);

        }
    }
}

3. Open the "Startup" TPLMSNavigationProvider.cs file folder "ABP.TPLMS.Mvc.Web" project in the Visual Studio editor in 2017, writes the code to load the menu. Bold code below.

using Abp.Application.Navigation;
