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”。
目录
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
////// 修改用户信息 /// /// 用户主键 ///分部视图 public ActionResult Modify(int id) { //角色列表 var _roles = new RoleManager().FindList(); List_listItems = new List (_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() @Html.ValidationSummary(true, "", new { @class = "text-danger" }) @Html.HiddenFor(model => model.UserID) @Html.LabelFor(model => model.RoleID, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.DropDownListFor(model => model.RoleID, (IEnumerable )ViewBag.Roles, new { @class = "form-control" }) @Html.ValidationMessageFor(model => model.RoleID, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.Username, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.Username, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } }) @Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.Sex, htmlAttributes: new { @class = "control-label col-md-2" }) @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" }) @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.LastLoginTime, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.LastLoginTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } }) @Html.ValidationMessageFor(model => model.LastLoginTime, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.LastLoginIP, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.LastLoginIP, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } }) @Html.ValidationMessageFor(model => model.LastLoginIP, "", new { @class = "text-danger" }) @Html.LabelFor(model => model.RegTime, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.EditorFor(model => model.RegTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } }) @Html.ValidationMessageFor(model => model.RegTime, "", new { @class = "text-danger" }) } 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: "修改用户", message: function (dialog) { var $message = $(' '); 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
////// 删除 /// /// 用户ID ///[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 前台显示效果
