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; }
  }
}</usermodel></usermodel></usermodel>
