1、视图（显示）界面代码：
@{
Layout = null;
}
@using Mvc1.Models;
<!DOCTYPE html>
@{
if(Session["user"]==null)
{
Response.Redirect("Login");
}
}
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
<table style="background-color: navy; text-align: center; width: 100%;">
<tr style="color: white;">
<td>用户名</td>
<td>密码</td>
<td>昵称</td>
<td>性别</td>
<td>生日</td>
<td>民族</td>
<td>操作</td>
</tr>
@{
//先将数据取出来
List<Users> list = new UsersData().Select();
foreach (Users u in list)
{
<tr style="background-color: #e0e0e0;">
<td>@u.UserName</td>
<td>@u.PassWord</td>
<td>@u.NickName</td>
<td>@((bool)u.Sex ? "男" : "女")</td>
<td>@Convert.ToDateTime(u.Birthday).ToString("yyyy年MM月dd日")</td>
<td>@u.NationName</td>
<td>
<a href="Home/Update/@u.UserName">修改</a>
</td>
</tr>
}
}
</table>
</div>
</body>
</html>
2、视图（修改）界面代码：
@{
Layout = null;
}
@using Mvc1.Models;
@model Users
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Update</title>
</head>
<body>
<form name="form1" method="post" action="~/Home/UUU">
用户名：<input type="text" name="username" value="@Model.UserName" /><br />
密码：<input type="text" name="password" value="@Model.PassWord" /><br />
昵称：<input type="text" name="nickname" value="@Model.NickName" /><br />
性别：
@{
if ((bool)Model.Sex)
{
<input type="radio" name="sex" checked="checked" value="True" />@:男
<input type="radio" name="sex" value="False" />@:女
}
else
{
<input type="radio" name="sex" value="True" />@:男
<input type="radio" name="sex" checked="checked" value="False" />@:女
}
}
<br />
生日：
<select id="year" onchange="DateChange()">
@{
for (int i = DateTime.Now.Year; i > 1900; i--)
{
if (Convert.ToDateTime(Model.Birthday).Year == i)
{
<option selected="selected">@i</option>
}
else
{
<option>@i</option>
}
}
}
</select>年
<select id="month" onchange="DateChange()">
@{
for (int i = 1; i <= 12; i++)
{
if (Convert.ToDateTime(Model.Birthday).Month == i)
{
<option selected="selected">@i</option>
}
else
{
<option>@i</option>
}
}
}
</select>月
<select id="day" onchange="DateChange()">
@{
for (int i = 1; i <= 31; i++)
{
if (Convert.ToDateTime(Model.Birthday).Day == i)
{
<option selected="selected">@i</option>
}
else
{
<option>@i</option>
}
}
}
</select>日
<input type="text" id="birthday" name="birthday" style="display:none;" value="@Model.Birthday" />
<br />
民族：
<select name="nation">
@{
List<Nation> Nlist = new NationData().Select();
foreach (var n in Nlist)
{
if (Model.Nation == n.NationCode)
{
<option value="@n.NationCode" selected="selected">@n.NationName</option>
}
else
{
<option value="@n.NationCode">@n.NationName</option>
}
}
}
</select>
<br />
<input type="button" value="提交" onclick="form1.submit()" />
</form>
</body>
</html>
<script type="text/javascript">
function DateChange() {
var year = document.getElementById(‘year‘).value;
var month = document.getElementById(‘month‘).value;
var day = document.getElementById(‘day‘).value;
document.getElementById(‘birthday‘).value = year + "-" + month + "-" + day;
}
</script>
3、控制层控制器代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Mvc1.Models;
namespace Mvc1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
public ActionResult Update(string id)
{
Users u = new UsersData().Select(id);
return View(u);
}
public ActionResult UUU(Users data)
{
new UsersData().Update(data);
return RedirectToAction("Index", "Home");
}
}
}
4、模型层代码：
民族表查询
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Mvc1.Models
{
public class NationData
{
Data0425DataContext con = new Data0425DataContext();
public List<Nation> Select()
{
return con.Nation.ToList();
}
}
}
民族字段扩展
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Mvc1.Models
{
public partial class Users
{
Data0425DataContext con = new Data0425DataContext();
public string NationName
{
get {
return con.Nation.Where(r => r.NationCode == this.Nation).FirstOrDefault().NationName;
}
}
}
}
数据操作方法
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Mvc1.Models
{
public class UsersData
{
Data0425DataContext con = new Data0425DataContext();
public List<Users> Select()
{
return con.Users.ToList();
}
public Users Select(string uname)
{
return con.Users.Where(r => r.UserName == uname).FirstOrDefault();
}
public void Update(Users uuu)
{
Users u = con.Users.Where(r => r.UserName == uuu.UserName).FirstOrDefault();
u.PassWord = uuu.PassWord;
u.NickName = uuu.NickName;
u.Sex = uuu.Sex;
u.Birthday = uuu.Birthday;
u.Nation = uuu.Nation;
con.SubmitChanges();
}
}
}
