这里和单纯查询工能不同，这里是根据父级ID查询出子级的信息
Layout View部分
@using Droplets.Models; @{ Layout = null; List<LanMu2> lanmu2 = ViewBag.LanMu2Name; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <link href="~/Content/easyui.css" rel="stylesheet" /> <link href="~/Content/icon.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.8.2.min.js"></script> <script src="~/Scripts/jquery.easyui.min.js"></script> <script src="~/Scripts/easyui-lang-zh_CN.js"></script> <title>Index</title> <script type="text/javascript"> //function lanmu() { // $('#content').attr('src','/Admin/Index'); //} function wenzhang(id) { $('#content').attr('src', '/WenZhang/Index?id='+id); } </script> <style type="text/css"> .Ding { height: 210px; background-image: url('/Content/background_1/3.jpg'); } </style> </head> <body class="easyui-layout"> <div class="Ding" data-options="region:'north',split:true" style="height:120px;"><h1>网站后台管理系统</h1></div> <div data-options="region:'west',title:'导航菜单',split:true" style="150px;"> <ul class="easyui-tree"> @if (lanmu2 != null) { foreach (LanMu2 item1 in lanmu2) { <li> <a onclick="wenzhang('@item1.Id')">@item1.Name</a> </li> } } <li>修改密码</li> <li>退出</li> </ul> </div> <div data-options="region:'center',title:'内容'" style="padding:5px;background:#eee;"> <iframe id="content" style="100%;height:98%"></iframe> </div> </body> </html>
ManagementController部分：
public class ManagementController : AppController { // // GET: /Management/ Droplets.Models.DropletsEntities db; public ManagementController() { db = new DropletsEntities(); } protected override void Dispose(bool disposing) { if (disposing) { db.Dispose(); } base.Dispose(disposing); } public ActionResult Index() { var n1 = from t1 in db.LanMu2 select t1; var list = n1.ToList(); ViewBag.LanMu2Name = list; return View(); } public ActionResult Login() { return View(); } [HttpPost] public ActionResult LoginPost(string name, string password) { return RedirectToAction("Index"); } }
显示View部分：

后台WenZhangController也有所改动：
public class WenZhangController : Controller { // // GET: /WenZhang/ public ActionResult Index(int id) { ViewBag.temp= id; return View(); } public ActionResult JsonPost(int id) { DropletsEntities dl = new DropletsEntities(); var p = from t in dl.WenZhang //join t2 in dl.LanMu2 on t.LanMu2_Id equals t2.Id 此处修改，不在全部显示 where t.LanMu2_Id==id select new { Id=t.Id, Title = t.Title, Editor = t.Editor, CreateTime = t.CreateTime, BrowseCount = t.BrowseCount, //LanMu2_Id = t2.Name, }; return Json(p, JsonRequestBehavior.AllowGet); } public ActionResult Edit(int id) { WenZhang wenzhang; if (id > 0) { DropletsEntities dao = new DropletsEntities(); var q = from t in dao.WenZhang where t.Id == id select t; wenzhang = q.FirstOrDefault(); } else wenzhang = new WenZhang(); DropletsEntities dao1 = new DropletsEntities(); var list = (from t in dao1.LanMu2 select new { Id = t.Id, Name = t.Name }).ToList(); if (id == 0) { //4个参数：1数据，2值字段，3显示字段，4选中值 ViewBag.LanMu2_Id = new SelectList(list, "Id", "Name", 1); } else { DropletsEntities newent = new DropletsEntities(); var q = from t in newent.LanMu2 where t.Id == wenzhang.LanMu2_Id select t; LanMu2 e = q.FirstOrDefault(); ViewBag.LanMu2_Id = new SelectList(list, "Id", "Name", e.Id); } return View(wenzhang); } [HttpPost] [ValidateInput(false)] public ActionResult EditPost(WenZhang wenzhang) { DropletsEntities dao = new DropletsEntities(); if (wenzhang.Id == 0) { wenzhang.CreateTime = DateTime.Now; dao.WenZhang.Add(wenzhang); } else { var temp = dao.WenZhang.FirstOrDefault(t => t.Id == wenzhang.Id); temp.Title = wenzhang.Title; temp.Editor = wenzhang.Editor; temp.LanMu2_Id = wenzhang.LanMu2_Id; temp.Content = wenzhang.Content; temp.PictureCaptions = wenzhang.PictureCaptions; } dao.SaveChanges(); dao.Dispose(); return RedirectToAction("Edit", new { id = wenzhang.Id }); } [HttpPost] public ActionResult Delete(int id) { DropletsEntities dao = new DropletsEntities(); var q = dao.WenZhang.FirstOrDefault(t => t.Id ==id); dao.WenZhang.Remove(q); dao.SaveChanges(); return RedirectToAction("Index"); } }
