常规的Jquery Ajax 验证登录,主要有3种服务端页面相应 ,也就是 aspx,ashx,asmx即webserivice 。 

下面分别用3种方式来(aspx,ashx,asmx)做服务端来处理 Jquery  Ajax 传过来的用户名和密码验证!

例: Login.html 请求用户名和密码验证!

<head>
<script type="text/javascript">

        $(document).ready(function() {
            $("#go").bind(click, function() {

              
                var name = $.trim($("#txtName").val());     // $.trim()去除空格
                var pwd = $.trim($("#txtPwd").val());

                if (name == "") { $("#nameResult").html("<font color=‘red‘>用户名不能为空</font>"); }
                else { $("#nameResult").html(""); }
                if (pwd == "") { $("#pwdResult").html("<font color=‘red‘>密码不能为空</font>"); }
                else { $("#pwdResult").html(""); }

                if (name != "" && pwd != "") {
                    //post 请求
                    $.ajax({
                    type: "post",
                    //服务器相应ajax请求,可以有 aspx页面,ashx页面     url: "AjaxLogin.aspx","AjaxLoginAshx.ashx",
                    url: "AjaxLoginAsmx.asmx/login",          //调用 webserivice 下的login方法
                        cache: false,
                        data: "name=a&&pwd=b",
                        //aspx页面为服务器相应
                         success: function(html) { location.href = "default.aspx"; $("#go").attr("disabled", false) },

                      
                     
                        error: function(html) { alert("登录失败"); $("#go").attr("disabled", false) }


                    });
                }


            });
        });
        
     
    
    </script>
</head>


<body>
    <form id="form1" runat="server">
    <div>
     用户名<asp:TextBox ID="txtName" runat="server" ></asp:TextBox><span id="nameResult"></span>
     <br />
     密码<asp:TextBox ID="txtPwd" runat="server"></asp:TextBox><span id="pwdResult"></span>
     <br />
     <br />
     
     <input type="button"  id="go" value="登录" />
     <asp:Button ID="go1" runat="server" Text="服务器控件登录" onclick="go_Click" />
    </div>
    </form>
</body>

1.服务端为 AjaxLogin.aspx 页面

首先修改 $.ajax 的 Url:"AjaxLogin.aspx"

protected void Page_Load(object sender, EventArgs e)
        {

            if (Request.Form["name"] != null && Request.Form["pwd"] != null)
            {
                if (Request.Form["name"].ToString().Trim() != "" && Request.Form["pwd"].ToString() != "")
                {

                    string name = Request.Form["name"].ToString().Trim();
                    string pwd = Request.Form["pwd"].ToString();
                    Response.Cookies.Clear();
                    
                    Response.Cookies.Add(new HttpCookie("name", name)); //添加cookie
                    Response.Cookies.Add(new HttpCookie("pwd",pwd));//添加密码


                    Response.Write("你已经成功登录"); 

                }


            }
           
        }

2. 服务端为 AjaxLoginAshx.ashx 页面  (一般处理程序)

首先修改 $.ajax 的 Url:"AjaxLoginAshx.ashx"; 另:ashx以context.Response.Write 返回内容

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    public class AjaxLoginAshx : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            //context.Response.ContentType = "text/plain";
            //context.Response.Write("Hello World");
            if (context.Request.Form["name"] != null && context.Request.Form["pwd"] != null)
            {
                if (context.Request.Form["name"].ToString().Trim() != "" && context.Request.Form["pwd"].ToString() != "")
                {

                    string name = context.Request.Form["name"].ToString().Trim();
                    string pwd = context.Request.Form["pwd"].ToString();
                    context.Response.Cookies.Clear();

                    context.Response.Cookies.Add(new HttpCookie("name", name));
                    context.Response.Cookies.Add(new HttpCookie("pwd", pwd));


                    context.Response.Write("你已经成功登录");






                }
                else
                {

                    context.Response.Write("没成功登录1");
                }


            }
            else
            {

                context.Response.Write("没成功登录2");
            }
        
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }

3. 服务端为 AjaxLoginAsmx.asmx页面  (SOAP方式HTTP访问,用XML返回)

   首先修改 $.ajax 的 Url:"AjaxLoginAsmx.asmx/login";   注意:  / 后面是方法名

另asmx页面以return 返回内容,response.cookies.add添加cookie

/// <summary>
    /// AjaxLoginAsmx 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    public class AjaxLoginAsmx : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }

        [WebMethod]

        public string login()
        {
           

            if (HttpContext.Current.Request.Form["name"] != null && HttpContext.Current.Request.Form["pwd"] != null)
            {
                if (HttpContext.Current.Request.Form["name"].ToString().Trim() != "" && HttpContext.Current.Request.Form["pwd"].ToString() != "")
                {

                    string name = HttpContext.Current.Request.Form["name"].ToString().Trim();
                    string pwd = HttpContext.Current.Request.Form["pwd"].ToString();


                    //HttpContext.Current.Response.Cookies.Add(new HttpCookie("name", name));
                    //HttpContext.Current.Response.Cookies.Add(new HttpCookie("pwd", pwd));


                    //HttpContext.Current.Response.Write("你已经成功登录");
                    HttpContext.Current.Response.Cookies.Add(new HttpCookie("a", "123"));
                    return "Hello World";

 

                }
                else
                {
                    return "error1";
                }


            }

            else
            {
                return "error2";
            }

        }
