ASP.NET MVC5網站開發之用戶資料的修改和刪除3（七）

這次主要實現管理后臺界面用戶資料的修改和刪除，修改用戶資料和角色是經常用到的功能，但刪除用戶的情況比較少，為了功能的完整性還是坐上了。主要用到兩個action “Modify”和“Delete”。

一、用戶資料修改（Modify）

此功能分兩個部分：

public ActionResult Modify(int id) 用于顯示用戶信息

[httppost]

public ActionResult Modify(FormCollection form)用戶就收前臺傳來的信息并修改

1、顯示用戶信息

/// summary>
  /// 修改用戶信息
  /// /summary>
  /// param name="id">用戶主鍵/param>
  /// returns>分部視圖/returns>
  public ActionResult Modify(int id)
  {
   //角色列表
   var _roles = new RoleManager().FindList();
   ListSelectListItem> _listItems = new ListSelectListItem>(_roles.Count());
   foreach (var _role in _roles)
   {
    _listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() });
   }
   ViewBag.Roles = _listItems;
   //角色列表結束
   return PartialView(userManager.Find(id));
  }

此action有一個參數id,接收傳入的用戶ID,在action中查詢角色信息，并利用viewBage傳遞到視圖，并通過return PartialView(userManager.Find(id))向視圖傳遞用戶模型返回分部視圖。

視圖代碼如下：

@model Ninesky.Core.User

@using (Html.BeginForm())
{
 @Html.AntiForgeryToken()

 div class="form-horizontal">
  @Html.ValidationSummary(true, "", new { @class = "text-danger" })
  @Html.HiddenFor(model => model.UserID)

  div class="form-group">
   @Html.LabelFor(model => model.RoleID, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.DropDownListFor(model => model.RoleID, (IEnumerableSelectListItem>)ViewBag.Roles, new { @class = "form-control" })
    @Html.ValidationMessageFor(model => model.RoleID, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.Username, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.Username, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })
    @Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
    @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.Sex, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.RadioButtonFor(model => model.Sex, 1) 男
    @Html.RadioButtonFor(model => model.Sex, 0) 女
    @Html.RadioButtonFor(model => model.Sex, 2) 保密
    @Html.ValidationMessageFor(model => model.Sex, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })
    @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })
    @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.LastLoginTime, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.LastLoginTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })
    @Html.ValidationMessageFor(model => model.LastLoginTime, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.LastLoginIP, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.LastLoginIP, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })
    @Html.ValidationMessageFor(model => model.LastLoginIP, "", new { @class = "text-danger" })
   /div>
  /div>

  div class="form-group">
   @Html.LabelFor(model => model.RegTime, htmlAttributes: new { @class = "control-label col-md-2" })
   div class="col-md-10">
    @Html.EditorFor(model => model.RegTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })
    @Html.ValidationMessageFor(model => model.RegTime, "", new { @class = "text-danger" })
   /div>
  /div>

 /div>
}

2、修改用戶資料的后臺處理

[HttpPost]
  [ValidateAntiForgeryToken]
  public ActionResult Modify(int id,FormCollection form)
  {
   Response _resp = new Auxiliary.Response();
   var _user = userManager.Find(id);
   if (TryUpdateModel(_user, new string[] { "RoleID", "Name", "Sex", "Email" }))
   {
    if (_user == null)
    {
     _resp.Code = 0;
     _resp.Message = "用戶不存在，可能已被刪除，請刷新后重試";
    }
    else
    {
     if (_user.Password != form["Password"].ToString()) _user.Password = Security.SHA256(form["Password"].ToString());
     _resp = userManager.Update(_user);
    }
   }
   else
   {
    _resp.Code = 0;
    _resp.Message = General.GetModelErrorString(ModelState);
   }
   return Json(_resp);
  }

此方法有兩個參數id 和FormCollection form，不用User直接做模型的原因是因為user會把前臺所有數據都接收過來，這里我并不想允許修改用戶名，所以在方法中使用TryUpdateModel綁定允許用戶修改的屬性。TryUpdateModel在綁定失敗時同樣會在在ModelState中記錄錯誤，可以利用自定義方法GetModelErrorString獲取到錯誤信息并反饋給視圖。

2、前臺顯示和處理

打開Index視圖找到表格初始化方法，格式化列“Username”使其顯示一個連接，代碼紅線部分。

使其看起來這個樣子，當用戶點擊連接的時候可以顯示修改對話框

彈出窗口和發送到服務器的js代碼寫到表格的onLoadSuccess方法里

onLoadSuccess: function () {

     //修改
     $("a[data-method='Modify']").click(function () {
      var id = $(this).attr("data-value");
      var modifyDialog = new BootstrapDialog({
       title: "span class='glyphicon glyphicon-user'>/span>修改用戶",
       message: function (dialog) {
        var $message = $('div>/div>');
        var pageToLoad = dialog.getData('pageToLoad');
        $message.load(pageToLoad);

        return $message;
       },
       data: {
        'pageToLoad': '@Url.Action("Modify")/' + id
       },
       buttons: [{
        icon: "glyphicon glyphicon-plus",
        label: "保存",
        action: function (dialogItself) {
         $.post($("form").attr("action"), $("form").serializeArray(), function (data) {
          if (data.Code == 1) {
           BootstrapDialog.show({
            message: data.Message,
            buttons: [{
             icon: "glyphicon glyphicon-ok",
             label: "確定",
             action: function (dialogItself) {
              $table.bootstrapTable("refresh");
              dialogItself.close();
              modifyDialog.close();
             }
            }]

           });
          }
          else BootstrapDialog.alert(data.Message);
         }, "json");
         $("form").validate();
        }
       }, {
        icon: "glyphicon glyphicon-remove",
        label: "關閉",
        action: function (dialogItself) {
         dialogItself.close();
        }
       }]
      });
      modifyDialog.open();
     });
     //修改結束
}

顯示效果如下圖

二、刪除用戶

UserController中添加刪除方法

/// summary>
  /// 刪除
  /// /summary>
  /// param name="id">用戶ID/param>
  /// returns>/returns>
  [HttpPost]
  public ActionResult Delete(int id)
  {
   return Json(userManager.Delete(id));
  }

打開Index視圖找到表格初始化方法，添加“操作”列格式化列使其顯示一個刪除按鈕，代碼紅框部分。

前臺顯示效果

然后在表格的onLoadSuccess方法里剛寫的修改用戶信息的js代碼后面寫刪除用戶的js代碼

//修改結束

     //刪除按鈕
     $("a[data-method='Delete']").click(function () {
      var id = $(this).attr("data-value");
      BootstrapDialog.confirm("你確定要刪除" + $(this).parent().parent().find("td").eq(3).text() + "嗎？\n 建議盡可能不要刪除用戶。", function (result) {
       if (result) {
        $.post("@Url.Action("Delete", "User")", { id: id }, function (data) {
         if (data.Code == 1) {
          BootstrapDialog.show({
           message: "刪除用戶成功",
           buttons: [{
            icon: "glyphicon glyphicon-ok",
            label: "確定",
            action: function (dialogItself) {
             $table.bootstrapTable("refresh");
             dialogItself.close();
            }
           }]

          });
         }
         else BootstrapDialog.alert(data.Message);
        }, "json");
       }
      });
     });
     //刪除按鈕結束
    }
   });
   //表格結束

前臺顯示效果
