视图界面代码：
@{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <script src="~/js/jquery-1.7.1.min.js"></script> <title>Login</title> </head> <body> <div> 用户名：<input type="text" id="uname" /><br /> 密码：<input type="text" id="pwd" /><br /> <input type="button" value="登陆" id="btn1" /> </div> </body> </html> <script type="text/javascript"> $("#btn1").click(function () { var a = $("#uname").val(); var b = $("#pwd").val(); $.ajax({ url: "/Ashxs/tttt.ashx", data: { "uname": a, "pwd": b }, type: "post", dataType: "json", success: function (data) { if (data.has == "1") { window.location.href = "Index"; } else { alert(‘用户名密码输入有误！‘); } }, error: function () { alert(‘服务器连接失败！‘); } }); }); </script>
一般处理程序里的代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using Mvc1.Models; using System.Collections; namespace Mvc1.Ashxs { public class Login : IHttpHandler { Data0425DataContext con = new Data0425DataContext(); public void ProcessRequest(HttpContext context) { string uname = context.Request["uname"].ToString(); string pwd = context.Request["pwd"].ToString(); string end = ""; Users uu = con.Users.Where(r => r.UserName == uname && r.PassWord == pwd).FirstOrDefault(); if (uu != null) { end = "{\"has\":\"1\"}"; } else { end = "{\"has\":\"0\"}"; } context.Response.Write(end); } public bool IsReusable { get { return false; } } } }
控制器界面代码：
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 Login() { return View(); } } }
