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;
}
}
}
