Ajax邮箱、用户名唯一性验证实例代码


            废话不多说了，直接给大家贴代码了，具体代码如下所示：







 <script type="text/javascript">

    $(function () { 

      $("#txtEmail").blur(function () {

        $.ajax({

          type: "post",

          url: "reg.ashx?email=" + $.trim($("#txtEmail").val()) + "&d=" + (+new Date()),

          success: function (data) {

            var vCount = parseInt(data);

            if (vCount == 0) {

              alert("邮箱可以使用");

            }

            else {

              alert("邮箱已经被占用");

            }

          }

        });

      });

      $("#checkpwd").blur(function () {

        return CheckPwd();

      });

    });

    function CheckPwd()

    {

      var bCheck = true;

      if ($.trim($("#pwd").val()) != $.trim($("#checkpwd").val()))

      {

        alert("两次密码输入不一致");

        bCheck = false;

      }

      return bCheck;

    }

  </script>



reg.ashx代码：





using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace WebT1.Ti.html2

{

  /// <summary>

  /// reg 的摘要说明

  /// </summary>

  public class reg : IHttpHandler

  {

    public void ProcessRequest(HttpContext context)

    {

      if (context.Request["email"] != null)

      {

        string strEmail = context.Request["email"];

        List<UserModel> lstUser = DataService.GetUserList();

        var v = lstUser.Where(p => p.Email == strEmail);

        int iCount = 0;

        if (v.Count() > 0)

        {

          iCount = 1;

        }

        context.Response.ContentType = "text/plain";

        context.Response.Write(iCount.ToString());

      }

    }

    public bool IsReusable

    {

      get

      {

        return false;

      }

    }

  }

  public class DataService

  {

    /// <summary>

    /// 模拟已注册用户数据

    /// </summary>

    public static List<UserModel> GetUserList()

    {

      var list = new List<UserModel>();

      list.Add(new UserModel() { Email = "t1@demo.com" });

      list.Add(new UserModel() { Email = "t2@demo.com" });

      list.Add(new UserModel() { Email = "t3@demo.com" });

      list.Add(new UserModel() { Email = "t4@demo.com" });

      list.Add(new UserModel() { Email = "t5@demo.com" });

      return list;

    }

  }

  public class UserModel

  {

    public string Email { get; set; }

  }

}
