1、视图页面

			
<!DOCTYPE html>
<html>
<head runat="server">
    <title>Index2</title>
    <script src="/Scripts/jquery-1.4.4。js" type="text/javascript"></script>
    <script type="text/javascript">
        var login = function () {
            var data = { "username": $.trim($("#username").val()), "pwd": $.trim($("#pwd").val()) }

//            $.post("/Home/Login", data, function (message) {
//                if (message.success) {
//                    alert(message.msg);
//                }
//                else {
//                    alert(message.msg);
//                }
//            }, "json");

            $.ajax({ type: "post", url: "/Home/Login", data: data, success: function (message) {
                if (message.Success) {
                    alert(message.Msg);
                }
                else {
                    alert(message.Msg);
                }
            }, dataType: "json"
            });
        }
    </script>
</head>
<body>
    <div id="nav">
        <a href="/Home/Index">ajax+Handler</a>  <a>ajax+action</a>
    </div>
    <div>
        <h3>
            Login</h3>
        Username:<input id="username" name="username" type="text" /><br />
        Userpass:<input id="pwd" name="pwd" type="password" /><br />
        <button type="button" onclick="login()">
            Submit</button>
    </div>
</body>
</html>

2、控制器

			
  using System.Web.Mvc;

namespace Mvc1.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            return View();
        }
        //
        // GET: /Home/Index2
        public ActionResult Index2()
        {
            return View();
        }

        // Post: /Home/Login
        [HttpPost]
        public JsonResult Login()
        {
            string username=Request["username"];
            string pwd = Request["pwd"];

            message msg = null;

            if (username == "rain" && pwd == "m123")
            {
                msg = new message(true, "Success");
            }
            else
            {
                msg = new message(false, "Fail");
            }

            return Json(msg);
        }
    }

    class message
    {
        bool success;
        string msg;

        public message(bool success, string msg)
        {
            this.success = success;
            this.msg = msg;
        }

        public bool Success
        {
            get { return success; }
            set { success = value; }
        }
        public string Msg
        {
            get { return msg; }
            set { msg = value; }
        }
    }
}
