同样的MyWebApp代码：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using Droplets.Models; using System.Web; namespace Droplets.WebCode { public static class MyWebApp { private const string SessionUser = "CurrentUser";//当前用户 public const string LoginUrl = "/Management/Login";//登录界面 public const string LogoutUrl = "/Management/Logout";//退出登录 public static Admin currentUser { get { if (HttpContext.Current == null) return null; return HttpContext.Current.Session[SessionUser] as Admin; } set { HttpContext.Current.Session[SessionUser] = value; } } public static Admin checkLogin() { var user = currentUser; if (user == null) { HttpContext.Current.Response.Redirect(LoginUrl); } return user; } public static void logout() { HttpContext.Current.Session.Remove(SessionUser); } } }
View部分：
@model Droplets.Models.Admin @using Droplets.Models @using Droplets.WebCode @{ Layout = null; Admin admin = MyWebApp.currentUser; string message = ViewBag.message; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <link href="~/Content/easyui.css" rel="stylesheet" /> <link href="~/Content/icon.css" rel="stylesheet" /> <link href="~/Content/demo.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.8.2.min.js"></script> <script src="~/Scripts/jquery.easyui.min.js"></script> <title>修改密码</title> <script type="text/javascript"> function submitForm() { var oldpass = $('#oldpass').val(); var newpass = $('#newpass').val(); var newpass1 = $('#newpass1').val(); if (newpass != newpass1) { alert('两次输入的新密码不一致！') return false; } if (oldpass == newpass && newpass == newpass1) { alert('新密码不能和旧密码相同！') return false; } $('#form1').submit(); } function reset(){ $('#form1').form('clear'); } </script> @if (!string.IsNullOrEmpty(message)) { <script type="text/javascript"> $(function() { alert("@message"); }); </script> } <style type="text/css"> #div1 { position: absolute; top: 50%; left: 50%; margin: -150px 0 0 -200px; border: 1px solid #008800; } </style> </head> <body> <div id="div1"> <div class="easyui-panel" title="密码修改" style="500px;padding:30px 60px"> <div style="margin-bottom:30px"> <form method="post" id="form1" action="/Admin/Index"> <table> <tbody> <tr style="margin-bottom:20px"> <td><label>用户名：</label></td> <td><lable>@admin.Name</lable></td> </tr> <tr style="margin-bottom:20px"> <td><lable>旧密码：</lable></td> <td><input class="easyui-textbox" id="oldpass" type="password" name="oldpass"></td> </tr> <tr style="margin-bottom:20px"> <td><lable>新密码：</lable></td> <td><input class="easyui-textbox" id="newpass" type="password" name="newpass"></td> </tr> <tr style="margin-bottom:20px"> <td><lable>确认新密码：</lable></td> <td><input class="easyui-textbox" id="newpass1" type="password" name="newpass1"></td> </tr> </tbody> </table> <div style="margin-top:30px"> <a href="#" class="easyui-linkbutton" onclick="submitForm()" style="20%;margin-left:10%">提交</a> <a href="#" class="easyui-linkbutton" onclick="reset()" style="20%;margin-left:10%">重置</a> @*<input type="submit" value="提交" style="60px;height:30px;margin-right:50px" /> <input type="reset" value="取消" style="60px;height:30px" />*@ </div> </form> </div> </div> </div> </body> </html>
AdminController部分：
using System.Web.Mvc; //要引入的 public class AdminController : Controller { // // GET: /Admin/ Droplets.Models.DropletsEntities db; public AdminController() { db = new DropletsEntities(); } protected override void Dispose(bool disposing) { if (disposing) { db.Dispose(); } base.Dispose(disposing); } public ActionResult Index() { var admin = MyWebApp.checkLogin(); if (admin == null) { return RedirectToAction("/Managemnet/Login"); } return View(); } [HttpPost] [ActionName("Index")] public ActionResult IndexPost() { string AdminName = MyWebApp.currentUser.Name; var temp = db.Admin.FirstOrDefault(t => t.Name == AdminName); string pas = temp.PassWord; if (pas != Request.Form["oldpass"]) { ViewBag.message = "旧密码输入错误"; } else { temp.PassWord = Request.Form["newpass"]; db.SaveChanges(); ViewBag.message = ("密码修改成功！"); } return View("Index"); } }
