ASP.NET MVC5 網站開發實踐(二) Member區域管理列表、回復及刪除

/// <summary>
        /// 咨詢管理
        /// </summary>
        /// <returns></returns>
        public ActionResult ManageList()
        {
            return View();
        }

添加返回json數據的ManageJsonList

public JsonResult ManageJsonList(int pageIndex = 1, int pageSize = 20)
        {
            int _total;
            var _list = commonModelService.FindPageList(out _total, pageIndex, pageSize, "Consultation", string.Empty, 0, string.Empty, null, null, 0).ToList().Select(
                cm => new Ninesky.Web.Models.CommonModelViewModel()
                {
                    CategoryID = cm.CategoryID,
                    CategoryName = cm.Category.Name,
                    DefaultPicUrl = cm.DefaultPicUrl,
                    Hits = cm.Hits,
                    Inputer = cm.Inputer,
                    Model = cm.Model,
                    ModelID = cm.ModelID,
                    ReleaseDate = cm.ReleaseDate,
                    Status = cm.Status,
                    Title = cm.Title
                });
            return Json(new { total = _total, rows = _list.ToList() });
        }

右鍵為ManageList添加試圖

@{
    ViewBag.Title = "咨詢管理";
}

<div id="toolbar">
    <div>
        <a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-remove',plain:true" onclick="del()">刪除</a>
        <a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-reload',plain:true" onclick="$('#Consultation_List').datagrid('reload');">刷新</a>
    </div>
</div>

<table id="Consultation_List"></table>

<script src="~/Scripts/Common.js"></script>
<script src="~/Scripts/jquery.easyui.datagrid.detailview.js"></script>
<script type="text/javascript">
    $("#Consultation_List").datagrid({
        loadMsg: '加載中……',
        fitColumns: true,
        pagination: true,
        url: '@Url.Action("ManageJsonList", "Consultation")',
        columns: [[
            { field: 'ModelID', title: 'ID', checkbox: true },
            { field: 'Title', title: '標題' },
            { field: 'Inputer', title: '咨詢人', align: 'right' },
            { field: 'ReleaseDate', title: '咨詢日期', align: 'right', formatter: function (value, row, index) { return jsonDateFormat(value); } },
            { field: 'StatusString', title: '狀態', width: 100, align: 'right' }
        ]],
        toolbar: '#toolbar',
        idField: 'ModelID',
        view: detailview,
        detailFormatter: function (rowIndex, rowData) { return '<div class="detail" style="width:100%,padding:5px 0"></div>'; },
        onExpandRow: function (index, row) {
            var detail = $(this).datagrid('getRowDetail', index).find('div.detail');
            $(detail).html("<iframe frameborder='0' marginwidth='0' height='160px' width='100%' src='@Url.Action("Reply", "Consultation")/" + row.ModelID + "'></iframe>");
            $('#Consultation_List').datagrid('fixDetailRowHeight', index);
        }
    });

</script>

二、回復評論

ManageList添加datagrid詳細視圖使用類框架（("<iframe frameborder='0' marginwidth='0' height='160px' width='100%' src='@Url.Action("Reply", "Consultation")/" + row.ModelID + "'></iframe>"）。“Consultation/Reply”就是我們回復的視圖。

在Consultation控制器，添加Reply方法

/// <summary>
        /// 回復
        /// </summary>
        /// <param name="id">id</param>
        /// <returns></returns>
        public ActionResult Reply(int id)
        {
            return View(commonModelService.Find(id).Consultation);
        }

右鍵添加視圖

@model Ninesky.Models.Consultation
@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    <table style="width:100%;font-size:12px;">
        <tr>
            <th>@Html.DisplayNameFor(model => model.Name)</th>
            <td>@Html.DisplayFor(model => model.Name)</td>
            <th>@Html.DisplayNameFor(model => model.IsPublic)</th>
            <td>@Html.DisplayFor(model => model.IsPublic)</td>
        </tr>
        <tr>
            <th>@Html.DisplayNameFor(model => model.QQ)</th>
            <td>@Html.DisplayFor(model => model.QQ)</td>
            <th>@Html.DisplayNameFor(model => model.Email)</th>
            <td>@Html.DisplayFor(model => model.Email)</td>
        </tr>
        <tr>
            <th>@Html.DisplayNameFor(model => model.Content)</th>
            <td colspan="3">@Html.DisplayFor(model => model.Content)</td>
        </tr>
        @if (Model.ReplyTime != null)
        {
            <tr>
                <td colspan="4">

                    <span>管理員于：@Model.ReplyTime 回復如下</span>
                    <br />
                    <p style=" margin-top:8px">
                        @Model.ReplyContent
                    </p>

                </td>
            </tr>
        }
        else
        {
            <tr>
                <th>
                    回復 @Html.HiddenFor(model => model.ConsultationID) 
                    @Html.ValidationMessageFor(model=>model.ConsultationID)
                </th>
                <td colspan="3">
                    @Html.TextAreaFor(model => model.ReplyContent, new { @class = "form-control" })
                    @Html.ValidationMessageFor(model=>model.ReplyContent)
                </td>
            </tr>
            <tr>
                <th>

                </th>
                <td colspan="3">
                    <input type="submit" class="btn_reply btn btn-primary" value="確定" />
                </td>
            </tr>
        }
    </table>
}

添加接收處理的方法。

[HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Reply()
        {
            CommonModel _commonModel = null;
            if (RouteData.Values.ContainsKey("id"))
            {
                int _modelId = int.Parse(RouteData.Values["id"].ToString());
                _commonModel = commonModelService.Find(_modelId);
                if (string.IsNullOrEmpty(Request.Form["ReplyContent"])) ModelState.AddModelError("ReplyContent", "必須輸入回復內容！");
                else
                {
                    _commonModel.Consultation.ReplyContent = Request.Form["ReplyContent"];
                    _commonModel.Consultation.ReplyTime = System.DateTime.Now;
                    _commonModel.Status = 29;
                    commonModelService.Update(_commonModel);
                }
            }
            return View(_commonModel.Consultation);
        }

過程是：

1、接收路由中的id參數（RouteData.Values.ContainsKey("id"))

2、查找該ID的CommonModel，并獲取客戶端傳過來的ReplyContent，設置其他參數（ReplyTime，Status）并保存到數據庫

3、返回視圖

三、刪除評論

在Consultation控制器，添加Delete方法

/// <summary>
        /// 刪除評論
        /// </summary>
        /// <param name="id">公共模型ID</param>
        /// <returns></returns>
        public ActionResult Delete(int id)
        {
            var _commonModel = commonModelService.Find(id);
            if (_commonModel == null) return Json(false);

            if (commonModelService.Delete(_commonModel)) return Json(true);
            else return Json(false);
        }

然后打開ManageList視圖，添加刪除js代碼

//刪除
    function del() {
        var rows = $("#Consultation_List").datagrid("getSelections");
        if (!rows || rows.length < 1) {
            $.messager.alert("提示", "未選擇任何行!");
            return;
        }
        else if (rows.length > 0) {
            $.messager.confirm("確認", "您確定要刪除所選行嗎？", function (r) {
                if (r) {
                    $.messager.progress();
                    $.each(rows, function (index, value) {
                        $.ajax({
                            type: "post",
                            url: "@Url.Action("Delete", "Consultation")",
                            data: { id: value.ModelID },
                            async: false,
                            success: function (data) {
                            }
                        });
                    });
                    $.messager.progress('close');
                    //清除選擇行
                    rows.length = 0;
                    $("#Consultation_List").datagrid('reload');
                }
            });
            return;
        }
