MVC4制作網站中如何更新欄目,很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
一、用戶
二、用戶組
三、欄目
3.1添加欄目
3.2瀏覽欄目
3.3更新欄目
在樹形列表里面點擊欄目名稱后跳轉到詳細信息頁面~/Category/ManageDetails/id。在詳細頁面里點修改,來完成欄目資料修改。
先打開【CategoryController】添加[ManageDetails(int id)]action
/// <summary> /// 欄目詳細資料 /// </summary> /// <param name="id"></param> /// <returns></returns> public ActionResult ManageDetails(int id) { categoryRsy = new CategoryRepository(); var _node = categoryRsy.Find(id); if (_node == null) { Error _e = new Error { Title = "欄目不存在", Details = "欄目不存在", Cause = Server.UrlEncode("<li>欄目已經刪除</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("Manage", "Cayegory") + "'>欄目欄目管理</a></li>") }; return RedirectToAction("ManageError", "Prompt", _e); } ModuleRepository _moduleRsy = new ModuleRepository(); var _modules = _moduleRsy.List(true); List<SelectListItem> _slimodule = new List<SelectListItem>(_modules.Count()); foreach (Module _module in _modules) { if (_node.Model == _module.Model) _slimodule.Add(new SelectListItem { Text = _module.Name, Value = _module.Model, Selected = true }); else _slimodule.Add(new SelectListItem { Text = _module.Name, Value = _module.Model }); } ViewData.Add("Model", _slimodule); var _type = TypeSelectList; _type.SingleOrDefault(t => t.Value == _node.Type.ToString()).Selected = true; ViewData.Add("Type", _type); return View(_node); }
代碼先是看欄目是否存在,不存在跳轉到錯誤頁面,后面是添加"Model“和“Type”的ViewData
右鍵添加強類型視圖ManageDetails.cshtml,內容基本與ManageAdd.cshtml類似
@model Ninesky.Models.Category @{ ViewBag.Title = "欄目信息"; Layout = "~/Views/Layout/_Manage.cshtml"; } <div class="workspace"> <div class="inside"> <div class="notebar"> <img alt="" src="~/Skins/Default/Manage/Images/Category.gif" />欄目信息 </div> @using (Html.BeginForm("ManageUpdate","Category")) { @Html.ValidationSummary(true) <fieldset> <legend>詳細資料</legend> <ul> @Html.HiddenFor(model => model.CategoryId) <li> <div class="editor-label"> @Html.LabelFor(model => model.CategoryId) </div> <div class="editor-field"> @Html.DisplayTextFor(model => model.CategoryId) </div> </li> <li> <div class="editor-label"> @Html.LabelFor(model => model.Name) </div> <div class="editor-field"> @Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) </div> </li> <li> <div class="editor-label"> @Html.LabelFor(model => model.ParentId) </div> <div class="editor-field"> @Html.TextBoxFor(model => model.ParentId, new { @class = "easyui-combotree", data_options = "url:'" + Url.Action("JsonTreeParent", "Category") + "'" }) @Html.ValidationMessageFor(model => model.ParentId) </div> </li> <li> <div class="editor-label"> @Html.LabelFor(model => model.Type) </div> <div class="editor-field"> @Html.DropDownList("Type") @Html.ValidationMessageFor(model => model.Type) </div> </li> <li id="li_model"> <div class="editor-label"> @Html.LabelFor(model => model.Model) </div> <div class="editor-field"> @Html.DropDownList("Model") @Html.ValidationMessageFor(model => model.Model) </div> </li> <li id="li_categoryview"> <div class="editor-label"> @Html.LabelFor(model => model.CategoryView) </div> <div class="editor-field"> @Html.EditorFor(model => model.CategoryView) @Html.ValidationMessageFor(model => model.CategoryView) </div> </li> <li id="li_contentview"> <div class="editor-label"> @Html.LabelFor(model => model.ContentView) </div> <div class="editor-field"> @Html.EditorFor(model => model.ContentView) @Html.ValidationMessageFor(model => model.ContentView) </div> </li> <li id="li_nav"> <div class="editor-label"> @Html.LabelFor(model => model.Navigation) </div> <div class="editor-field"> @Html.EditorFor(model => model.Navigation) @Html.ValidationMessageFor(model => model.Navigation) </div> </li> <li> <div class="editor-label"> @Html.LabelFor(model => model.Order) </div> <div class="editor-field"> @Html.EditorFor(model => model.Order) @Html.ValidationMessageFor(model => model.Order) </div> </li> <li> <div class="editor-label"> <input id="Submit1" type="submit" value="修改" /> </div> <div class="editor-field"> </div> </li> </ul> </fieldset> } </div> </div> <div class="left"> <div class="top"></div> @Html.Action("ManagePartialTree", "Category") </div> <div class="split"></div> <div class="clear"></div> <script type="text/javascript"> Details(); $("#Type").change(function () { Details(); }); function Details() { var v = $("#Type").val(); if (v == "0") { $("#li_model").show(); $("#li_categoryview").show(); $("#li_contentview").show(); $("#li_nav").hide(); $("#Navigation").val(""); } else if (v == "1") { $("#li_model").hide(); $("#li_categoryview").show(); $("#li_contentview").hide(); $("#ContentView").val(""); $("#li_nav").hide(); $("#Navigation").val(""); } else if (v == "2") { $("#li_model").hide(); $("#li_categoryview").hide(); $("#CategoryView").val(""); $("#li_contentview").hide(); $("#ContentView").val(""); $("#li_nav").show(); } } </script> @section Scripts { @Styles.Render("~/EasyUi/icon") @Scripts.Render("~/bundles/EasyUi") @Scripts.Render("~/bundles/jqueryval") }
注意的是 @using (Html.BeginForm("ManageUpdate","Category"))這句;表示點修改按鈕的后是向ManageUpdate提交數據。下面開始做這個action
在【CategoryController】里添加httppost方式的[ManageUpdate]action
/// <summary> /// 修改欄目信息 /// </summary> /// <param name="category"></param> /// <returns></returns> public ActionResult ManageUpdate(Category category) { switch (category.Type) { case 0: category.Navigation = ""; break; case 1: category.Model = ""; category.ContentView = ""; category.Navigation = ""; break; case 2: category.Model = ""; category.CategoryView = ""; category.ContentView = ""; break; } categoryRsy = new CategoryRepository(); if (categoryRsy.Update(category)) { Notice _n = new Notice { Title = "修改欄目成功", Details = "修改欄目成功!", DwellTime = 5, NavigationName = "欄目詳細信息", NavigationUrl = Url.Action("ManageDetails", "Category", new { id = category.CategoryId }) }; return RedirectToAction("ManageNotice", "Prompt", _n); } else { Error _e = new Error { Title = "修改欄目失敗", Details = "在修改欄目信息時,未能保存到數據庫", Cause = "系統錯誤", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("ManageDetails", "Category", new { id = category.CategoryId }) + "'>欄目詳細資料</a>頁面,修改信息后重新操作</li><li>聯系網站管理員</li>") }; return RedirectToAction("ManageError", "Prompt", _e); } }
很簡單,首先是判斷欄目類型,根據欄目類型清除無關數據,然后將修改保存到數據庫。
試一下將“測試欄目”改成“公司簡介”
保存成功!
