今天就跟大家聊聊有關MVC4制作網(wǎng)站中如何瀏覽欄目,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結了以下內容,希望大家根據(jù)這篇文章可以有所收獲。
序
一、用戶
二、用戶組
三、欄目
3.1添加欄目
3.2瀏覽欄目
瀏覽欄目這塊做個一個樹形列表,添加欄目的左側部分只寫了句“左側列表”就是指這個樹形列表,等我們寫完替換一下就可以了。
先在【CategoryController】里面添加[ManagePartialTree]action,這里的Partial用來說明是分部視圖
/// <summary> /// 欄目列表局部樹視圖 /// </summary> /// <returns></returns> [AdminAuthorize] public ActionResult ManagePartialTree() { return View(); }
右鍵添加分部視圖ManagePartialTree.cshtml。分部視圖里用easyui的tree來顯示欄目,使用異步加載,視圖代碼只有一行。
復制代碼 代碼如下:
<ul id="ctree" class="easyui-tree" data-options="url:'@Url.Action("ManageTreeChildrenJson", "Category")'"></ul>
這里從[anageTreeChildrenJson]action獲取的json數(shù)據(jù)。
在【CategoryController】添加JsonResult類型的[anageTreeChildrenJson]
/// <summary> /// 子欄目樹形控件Json數(shù)據(jù) /// </summary> /// <param name="id">欄目id</param> /// <returns></returns> [AdminAuthorize] public JsonResult ManageTreeChildrenJson(int id = 0) { categoryRsy = new CategoryRepository(); var _children = categoryRsy.Children(id); List<Tree> _trees = new List<Tree>(_children.Count()); foreach(var c in _children) { Tree _t = new Tree { id = c.CategoryId, text = c.Name}; switch (c.Type) { case 0: _t.state = "closed"; _t.iconCls = "icon-general"; break; case 1: _t.state = "open"; _t.iconCls = "icon-page"; break; case 2: _t.state = "open"; _t.iconCls = "icon-link"; break; } _trees.Add(_t); } return Json(_trees, JsonRequestBehavior.AllowGet); }
這里默認id=0,根據(jù)id查找子欄目,然后遍歷子欄目生成樹的節(jié)點數(shù)據(jù)。
switch (c.Type) 是根據(jù)欄目類型不同來,來設置節(jié)點狀態(tài)并,設置不同的圖標。最后以Json類型返回。
修改一下上一節(jié)中添加欄目的視圖ManageAdd.cshtml,將左側列表替換成@Html.Action("ManagePartialTree", "Category")。替換后ManageAdd.cshtml
@model Ninesky.Models.Category @{ ViewBag.Title = "ManageAdd"; Layout = "~/Views/Layout/_Manage.cshtml"; } <div class="workspace"> <div class="inside"> <div class="notebar"> <img alt="" src="~/Skins/Default/Manage/Images/Category.gif" />添加欄目 </div> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>欄目</legend> <ul> <li> <div class="editor-label"> @Html.LabelFor(model => model.Type) </div> <div class="editor-field"> @Html.DropDownList("Type") @Html.ValidationMessageFor(model => model.Type) @Html.DisplayDescriptionFor(model => model.Type) </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) @Html.DisplayDescriptionFor(model => model.Name) </div> </li> <li> <div class="editor-label"> @Html.LabelFor(model => model.ParentId) </div> <div class="editor-field"> @Html.TextBox("ParentId", 0, new { @class = "easyui-combotree", data_options = "url:'" + Url.Action("JsonTreeParent", "Category") + "'" }) @Html.ValidationMessageFor(model => model.ParentId) @Html.DisplayDescriptionFor(model => model.ParentId) </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) @Html.DisplayDescriptionFor(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) @Html.DisplayDescriptionFor(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) @Html.DisplayDescriptionFor(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) @Html.DisplayDescriptionFor(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, new { value = 0 }) @Html.ValidationMessageFor(model => model.Order) @Html.DisplayDescriptionFor(model => model.Order) </div> </li> <li> <div class="editor-label"> </div> <div class="editor-field"> <input type="submit" value="添加" /> </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(); } else if (v == "1") { $("#li_model").hide(); $("#li_categoryview").show(); $("#li_contentview").hide(); $("#li_nav").hide(); } else if (v == "2") { $("#li_model").hide(); $("#li_categoryview").hide(); $("#li_contentview").hide(); $("#li_nav").show(); } } </script> @section Scripts { @Styles.Render("~/EasyUi/icon") @Scripts.Render("~/bundles/EasyUi") @Scripts.Render("~/bundles/jqueryval") }
添加一個單頁類型節(jié)點,在添加一個鏈接類型節(jié)點看一下
點一下欄目樹前的小箭頭能夠顯示和關閉下級欄目。但點欄目名稱沒什么反應,我希望的是點欄目名稱能夠跳轉到欄目詳細信息頁面~/Category/ManageDetails/id,現(xiàn)在用js實現(xiàn)。打開ManagePartialTree.cshtml,在下面添加腳本。
<script type="text/javascript"> using("tree", function () { $("#ctree").tree({ onClick: function (node) { top.location ="@Url.Action("ManageDetails", "Category")/"+node.id; } }); }); </script>
完工。
