MVC4做网站后台:栏目管理1、添加栏目-续
栏目类型跟原来一样分为常规栏目、单页栏目和外部链接。根据栏目类型的不同要隐藏相应的表单和验证（服务器端验证）。另外一个是父栏目必须是常规栏目才行，easyui-combotree要用到树形json数据，考虑不用递归函数而是用ParentPath字段排序的方式实现。
首先在在【CategoryController】中添加这个action，代码
/// <summary> /// 栏目树 /// </summary> /// <param name="categoryId">栏目Id，调用所有栏目为0</param> /// <param name="categoryType">栏目类型-1所有栏目，0常规栏目</param> /// <param name="jsonType">返回的数据类型【默认（0）-EasyuiTree类型】</param> /// <returns>Json类型数据</returns> public JsonResult Tree(int categoryId = 0, int categoryType = 0, int jsonType = 0) { IQueryable<Category> _categorys; if (categoryType == -1) _categorys = categoryRepository.Progeny(categoryId).OrderByDescending(c => c.ParentPath).ThenBy(c => c.Order); else _categorys = categoryRepository.Progeny(categoryId, categoryType).OrderByDescending(c => c.ParentPath).ThenBy(c => c.Order); switch (jsonType) { default: List<EasyuiTreeNodeViewModel> _trees = new List<EasyuiTreeNodeViewModel>(); Dictionary<int, EasyuiTreeNodeViewModel> _nodes = new Dictionary<int, EasyuiTreeNodeViewModel>(); foreach (var _category in _categorys) { if (_trees.Exists(n => n.parentid == _category.CategoryId))//存在子节点 { var _childern = _trees.Where(n => n.parentid == _category.CategoryId).ToList(); _trees.RemoveAll(n => n.parentid == _category.CategoryId); _trees.Add(new EasyuiTreeNodeViewModel { parentid = _category.ParentId, id = _category.CategoryId, text = _category.Name, state = "open", children = _childern }); } else _trees.Add(new EasyuiTreeNodeViewModel { parentid = _category.ParentId, id = _category.CategoryId, text = _category.Name, state = "close"}); } return Json(_trees); } }
再在控制器中添加Add的局部视图方法
/// <summary> /// 添加栏目 /// </summary> /// <returns>局部视图</returns> public PartialViewResult Add() { return PartialView(new Category { CategoryView = "Index", ContentOrder = 0, ContentView = "Detail", Model = "", Order = 0, PageSize = 20, ParentId = 0, RecordName = "文章", RecordUnit = "篇", Type = 0 }); }
@model Ninesky.Models.Category <div class="c_navbar">栏目管理 >> 添加栏目</div> @using (Html.BeginForm("Add", "Category", FormMethod.Post, new { id = "categoryadd_form" })) { @Html.AntiForgeryToken() <div class="fs_wapper"> <div class="header">添加栏目</div> @Html.ValidationSummary() <table class="fieldset"> <tr> <th>@Html.LabelFor(model => model.Name)<span>*</span></th> <td>@Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) @Html.DisplayDescriptionFor(model => model.Name) </td> </tr> <tr> <th>@Html.LabelFor(model => model.ParentId)<span>*</span></th> <td> <input id="ParentId" name="ParentId" style="width: 200px;" data-url="@Url.Action("Tree", "Category")" value="@Model.ParentId" /> @Html.ValidationMessageFor(model => model.ParentId) </td> </tr> <tr> <th>@Html.LabelFor(model => model.Type)<span>*</span></th> <td> <input id="Type" name="Type" value="@Model.Type" /> @Html.ValidationMessageFor(model => model.Type) </td> </tr> <tr> <th>@Html.LabelFor(model => model.Model)<span>*</span></th> <td> <input id="Model" name="Model" value="@Model.Model" data-url="@Url.Action("Items", "Module", new { id = 1 })" /> @Html.ValidationMessageFor(model => model.Model) @Html.DisplayDescriptionFor(model => model.Model) </td> </tr> <tr> <th>@Html.LabelFor(model => model.CategoryView)<span>*</span></th> <td> <input id="CategoryView" class="easyui-combobox" name="CategoryView" data-options="valueField:'Name',textField:'Name',url:'@Url.Action("Views", "View", new { controllerName="Category" })'" value="@Model.CategoryView"> @Html.ValidationMessageFor(model => model.CategoryView) </td> </tr> <tr> <th>@Html.LabelFor(model => model.ContentView)<span>*</span></th> <td> <input id="ContentView" class="easyui-combobox" name="ContentView" data-url="@Url.Action("Views", "View")" data-options="valueField:'Name',textField:'Name',url:'@Url.Action("Views", "Category", new { controllerName="Article" })'" value="@Model.ContentView"> @Html.ValidationMessageFor(model => model.CategoryView) </td> </tr> <tr> <th>@Html.LabelFor(model => model.LinkUrl)<span>*</span></th> <td> @Html.EditorFor(model => model.LinkUrl) @Html.ValidationMessageFor(model => model.LinkUrl) @Html.DisplayDescriptionFor(model => model.LinkUrl) </td> </tr> <tr> <th>@Html.LabelFor(model => model.Order)<span>*</span></th> <td> @Html.EditorFor(model => model.Order) @Html.ValidationMessageFor(model => model.Order) @Html.DisplayDescriptionFor(model => model.Order) </td> </tr> <tr> <th>@Html.LabelFor(model => model.ContentOrder)<span>*</span></th> <td> <select id="ContentOrder" name="ContentOrder" class="easyui-combobox" style="width: 200px;" data-options="url:'@Url.Action("OrderList", "Item", new {area="" })',valueField:'Value',textField:'Name'"> </select> @Html.ValidationMessageFor(model => model.ContentOrder) @Html.DisplayDescriptionFor(model => model.ContentOrder) </td> </tr> <tr> <th>@Html.LabelFor(model => model.PageSize)<span>*</span></th> <td> @Html.EditorFor(model => model.PageSize) @Html.ValidationMessageFor(model => model.PageSize) @Html.DisplayDescriptionFor(model => model.PageSize) </td> </tr> <tr> <th>@Html.LabelFor(model => model.RecordUnit)<span>*</span></th> <td> @Html.EditorFor(model => model.RecordUnit) @Html.ValidationMessageFor(model => model.RecordUnit) @Html.DisplayDescriptionFor(model => model.RecordUnit) </td> </tr> <tr> <th>@Html.LabelFor(model => model.RecordName)<span>*</span></th> <td> @Html.EditorFor(model => model.RecordName) @Html.ValidationMessageFor(model => model.Name) @Html.DisplayDescriptionFor(model => model.RecordName) </td> </tr> <tr> <th></th> <td> <a id="CategoryAdd_Save" href="javascript:void()" class="easyui-linkbutton">保存</a> </td> </tr> </table> </div> @Scripts.Render("~/Areas/Admin/Scripts/Category.js"); <script type="text/javascript"> CategoryAddReady(); </script> } @Scripts.Render("~/bundles/jqueryval")
在category.js中添加相应的js函数
//Add视图添加载完成函数 function CategoryAddReady() { $.post($('#ParentId').attr('data-url'), null, function (data) { if (data == "") data = [{ id: 0, text: "无" }]; else { data.unshift({ id: 0, text: "无" }); } $('#ParentId').combotree({ required: true, data: data }); }); $('#Type').combobox({ valueField: 'id', textField: 'text', data: [{ 'id': 0, 'text': '常规栏目' }, { 'id': 1, 'text': '单页栏目' }, { 'id': 2, 'text': '外部链接' }], required: true, onSelect: function (rec) { CategoryAdd_TypeChange(rec.id); } }); $.post($('#Model').attr("data-url"), null, function (data) { if (data == "") data = [{ Model: "", Name: "无" }]; else { data.unshift({ Model: "", Name: "无" }); } $('#Model').combobox({ valueField: 'Model', textField: 'Name', data: data, required: true, onSelect: function (rec) { CategoryAdd_ModelChange(rec.Model); } }); }); $('#ContentView').parent().parent().hide(); $('#LinkUrl').parent().parent().hide(); $('#ContentOrder').parent().parent().hide(); $('#RecordUnit').parent().parent().hide(); $('#PageSize').parent().parent().hide(); $('#RecordName').parent().parent().hide(); //保存事件 $('#CategoryAdd_Save').click(function () { CategoryAdd_Save(); }); //CategoryAdd_TypeChange(0); } //Add视图类型切换事件 function CategoryAdd_TypeChange(typeId) { //常规栏目 if (typeId == 0) { //模型 $('#Model').parent().parent().show(); var _modelValue = $('#Model').combobox('getValue'); CategoryAdd_ModelChange(_modelValue); }//单页栏目 else if (typeId == 1) { //模型 $('#Model').parent().parent().hide(); //栏目视图 $('#CategoryView').parent().parent().show(); //内容视图 $('#ContentView').parent().parent().hide(); //链接地址 $('#LinkUrl').parent().parent().hide(); //内容排序 $('#ContentOrder').parent().parent().hide(); //每页记录数 $('#PageSize').parent().parent().hide(); //记录单位 $('#RecordUnit').parent().parent().hide(); //记录名称 $('#RecordName').parent().parent().hide(); }//外部链接 else if (typeId == 2) { //模型 $('#Model').parent().parent().hide(); //栏目视图 $('#CategoryView').parent().parent().hide(); //内容视图 $('#ContentView').parent().parent().hide(); //链接地址 $('#LinkUrl').parent().parent().show(); //内容排序 $('#ContentOrder').parent().parent().hide(); //每页记录数 $('#PageSize').parent().parent().hide(); //记录单位 $('#RecordUnit').parent().parent().hide(); //记录名称 $('#RecordName').parent().parent().hide(); } } //Add视图模型切换事件 function CategoryAdd_ModelChange(value) { if (value == "")//模型为无 { //栏目视图 $('#CategoryView').parent().parent().show(); //内容视图 $('#ContentView').parent().parent().hide(); //链接地址 $('#LinkUrl').parent().parent().hide(); //内容排序 $('#ContentOrder').parent().parent().hide(); //每页记录数 $('#PageSize').parent().parent().hide(); //记录单位 $('#RecordUnit').parent().parent().hide(); //记录名称 $('#RecordName').parent().parent().hide(); } else { $('#CategoryView').parent().parent().show(); //内容视图 $('#ContentView').parent().parent().show(); //链接地址 $('#LinkUrl').parent().parent().hide(); //内容排序 $('#ContentOrder').parent().parent().show(); //每页记录数 $('#PageSize').parent().parent().show(); //记录单位 $('#RecordUnit').parent().parent().show(); //记录名称 $('#RecordName').parent().parent().show(); var _modelValue = $('#Model').combobox('getValue'); $('#ContentView').combobox('reload', $('#ContentView').attr('data-url') + '?controllerName=' + _modelValue); } } //添加保存 function CategoryAdd_Save() { $('#categoryadd_form').form('submit', { success: function (data) { var rt = jQuery.parseJSON(data); //验证 Authentication(data.Authentication); //操作成功 if (rt.Success) { $(document.body).append("<div id='CategoryAdd_SuccessDialog'></div>"); $('#CategoryAdd_SuccessDialog').dialog({ title: '操作成功', width: 280, height: 138, closed: false, cache: false, content: '<br />添加栏目成功', modal: true, buttons:[{ text:'继续添加栏目', handler: function () { var _layout = $('#layout'); var _center = _layout.layout('panel', 'center'); _center.panel('refresh'); var _west = _layout.layout('panel', 'west'); _west.panel('refresh'); $('#CategoryAdd_SuccessDialog').dialog('destroy'); } },{ text:'关闭', handler: function () { var _layout = $('#layout'); var _west = _layout.layout('panel', 'west'); _west.panel('refresh'); $('#CategoryAdd_SuccessDialog').dialog('destroy'); } }] }); } else { var msg = ""; if (rt.ValidationList != undefined) ShowValidationMessage(rt.ValidationList); if (msg != "") msg = rt.Message + "<br /> <p> 原因如下：" + "<ul>" + msg + "</ul></p>"; else msg = rt.Message; $.messager.alert("添加栏目失败", msg, "error"); } } }); }
再次在控制器中添加处理action
[HttpPost] public JsonResult Add(Category category) { JsonViewModel _jdata = new JsonViewModel(); if (ModelState.IsValid)//模型验证通过 { //父栏目 if (category.ParentId == 0) category.ParentPath = "0"; else { var _parentCategory = categoryRepository.Find(category.ParentId); if (_parentCategory == null) ModelState.AddModelError("ParentId", "父栏目不存在。"); else if (_parentCategory.Type != 0) ModelState.AddModelError("ParentId", "父栏目不是常规栏目，不能添加子栏目。"); else category.ParentPath = _parentCategory.ParentPath + "," + _parentCategory.CategoryId; } //根据栏目类型验证字段 switch (category.Type) { case 0://常规栏目 if (string.IsNullOrEmpty(category.Model))//模型为空 { category.ContentView = category.LinkUrl = category.RecordUnit = category.RecordName = null; category.ContentOrder = category.PageSize = null; } else { if (string.IsNullOrEmpty(category.CategoryView)) ModelState.AddModelError("CategoryView", "栏目视图不能为空。"); if (string.IsNullOrEmpty(category.ContentView)) ModelState.AddModelError("ContentView", "内容视图不能为空。"); if (category.ContentOrder == null) ModelState.AddModelError("ContentOrder", "内容排序方式不能为空。"); if (category.PageSize == null) ModelState.AddModelError("PageSize", "每页记录数不能为空。"); if (string.IsNullOrEmpty(category.RecordUnit)) ModelState.AddModelError("RecordUnit", "记录单位不能为空。"); if (string.IsNullOrEmpty(category.RecordName)) ModelState.AddModelError("RecordName", "记录名称不能为空。"); category.LinkUrl = null; } break; case 1://单页栏目 if (string.IsNullOrEmpty(category.CategoryView)) ModelState.AddModelError("CategoryView", "栏目视图不能为空。");; category.Model = category.ContentView = category.LinkUrl = category.RecordUnit = category.RecordName = null; category.ContentOrder = category.PageSize = null; break; case 2: if (string.IsNullOrEmpty(category.LinkUrl)) ModelState.AddModelError("LinkUrl", "链接地址不能为空。"); category.Model = category.CategoryView = category.ContentView = category.RecordUnit = category.RecordName =category.ContentView = null; category.ContentOrder = category.PageSize = null; break; } //存在逻辑验证错误 if (!ModelState.IsValid) return Json(new JsonViewModel(ModelState)); else { if (categoryRepository.Add(category)) return Json(new JsonViewModel() { Success = true, Message = "添加栏目成功！" }); else return Json(new JsonViewModel() { Success = false, Message = "未能保存导数据库。" }); } } //模型验证失败 else return Json(new JsonViewModel(ModelState)); }
