<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; } } }
