这次主要实现管理后台界面用户资料的修改和删除，修改用户资料和角色是经常用到的功能，但删除用户的情况比较少，为了功能的完整性还是坐上了。主要用到两个action “Modify”和“Delete”。

一、用户资料修改（Modify）

此功能分两个部分：

public ActionResult Modify(int id) 用于显示用户信息

[httppost]

public ActionResult Modify(FormCollection form)用户就收前台传来的信息并修改

1、显示用户信息

/// <summary>  /// 修改用户信息  /// </summary>  /// <param name="id">用户主键</param>  /// <returns>分部视图</returns>  public ActionResult Modify(int id)  {   //角色列表   var _roles = new RoleManager().FindList();   List<SelectListItem> _listItems = new List<SelectListItem>(_roles.Count());   foreach (var _role in _roles)   {    _listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() });   }   ViewBag.Roles = _listItems;   //角色列表结束   return PartialView(userManager.Find(id));  }

此action有一个参数id,接收传入的用户ID,在action中查询角色信息，并利用viewBage传递到视图，并通过return PartialView(userManager.Find(id))向视图传递用户模型返回分部视图。

视图代码如下：

@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, (IEnumerable<SelectListItem>)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、修改用户资料的后台处理

[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 = "用户不存在，可能已被删除，请刷新后重试";    }    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);  }

此方法有两个参数id 和FormCollection form，不用User直接做模型的原因是因为user会把前台所有数据都接收过来，这里我并不想允许修改用户名，所以在方法中使用TryUpdateModel绑定允许用户修改的属性。TryUpdateModel在绑定失败时同样会在在ModelState中记录错误，可以利用自定义方法GetModelErrorString获取到错误信息并反馈给视图。

2、前台显示和处理

打开Index视图找到表格初始化方法，格式化列“Username”使其显示一个连接，代码红线部分。

使其看起来这个样子，当用户点击连接的时候可以显示修改对话框

弹出窗口和发送到服务器的js代码写到表格的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>修改用户",       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: "确定",             action: function (dialogItself) {              $table.bootstrapTable("refresh");              dialogItself.close();              modifyDialog.close();             }            }]           });          }          else BootstrapDialog.alert(data.Message);         }, "json");         $("form").validate();        }       }, {        icon: "glyphicon glyphicon-remove",        label: "关闭",        action: function (dialogItself) {         dialogItself.close();        }       }]      });      modifyDialog.open();     });     //修改结束}

显示效果如下图

二、删除用户

UserController中添加删除方法

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

打开Index视图找到表格初始化方法，添加“操作”列格式化列使其显示一个删除按钮，代码红框部分。

前台显示效果

然后在表格的onLoadSuccess方法里刚写的修改用户信息的js代码后面写删除用户的js代码

//修改结束     //删除按钮     $("a[data-method='Delete']").click(function () {      var id = $(this).attr("data-value");      BootstrapDialog.confirm("你确定要删除" + $(this).parent().parent().find("td").eq(3).text() + "吗？/n 建议尽可能不要删除用户。", function (result) {       if (result) {        $.post("@Url.Action("Delete", "User")", { id: id }, function (data) {         if (data.Code == 1) {          BootstrapDialog.show({           message: "删除用户成功",           buttons: [{            icon: "glyphicon glyphicon-ok",            label: "确定",            action: function (dialogItself) {             $table.bootstrapTable("refresh");             dialogItself.close();            }           }]          });         }         else BootstrapDialog.alert(data.Message);        }, "json");       }      });     });     //删除按钮结束    }   });   //表格结束
