Javascript·部分：

    <script language="javascript" type="text/javascript" src="../js/Common/jquery-1.4.2.min.js"></script>
        <script type="text/javascript">
            $(function () {
                var name = $("#loginname");
                var password = $("#password");
                $("#submit").click(function () {

                    if (name.val() == "") {
                        alert("아이디를 입력하십시오.");
                        name.focus();
                        return false;
                    } if (password.val() == "") {
                        alert("비밀번호를 입력하시오.");
                        password.focus();
                        return false;
                    }

                    $.ajax({
                        type: 'post',

                        success: function (text) {
                            if (text == "e") {
                                alert("로그인 정보를 확인하십시오！");

                        }
                    });
                });
            });

            function Submit() {
                if (event.keyCode == 13) {

                }
            }

    </script>

<%@ WebHandler Language="C#" Class="Login" %>

using System;
using System.Web;
using Service;
using Dao;

public class Login : IHttpHandler {
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";

        Tb_User user = ServiceLocator.UserService.UserModel(username.Trim(), System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(password.Trim(), "MD5").ToLower());

        if (null == user)
            context.Response.Write("e");    //确认登录信息【error】
