注册信息验证:
1 前台验证(js+Ajax):
首先像"邮箱格式","非空"验证可以通过js+正则表达式来完成;
另外像"用户名是否存在","邮箱是否已使用"可通过 Ajax向后台页面发请求,实现无页面刷新的验证()
2 仅仅是前台验证会存在一定的安全隐患,所以当用户提交时候还要实现后台验证
注意 验证"邮箱"的时候有一句
$.post("/ashx/ValidateReg.ashx", { "action": "mail", "userMail": val }, function (data) {
$("#msgEamil").css("display", "inline"); warnMsg("#msgEamil", data); }); using BookShopManager.Web.Common;using System;using System.Collections.Generic;using System.Web;using System.Web.SessionState;namespace BookShopManager.Web.Ashx{ /// /// ValidateReg 的摘要说明 /// 前台页面校验 /// public class ValidateReg : IHttpHandler, IRequiresSessionState { BLL.Users UserManager = new BLL.Users(); public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; string action = context.Request["action"]; if (action == "mail") { CheckedUserMail(context); } else if (action == "code") { string validateCode = context.Request["validateCode"]; if (ValidateCode.CheckValidateCode(validateCode)) { context.Response.Write("√"); } else { context.Response.Write("验证码错误"); } } else if (action == "name") { string loginName = context.Request["loginName"]; if (UserManager.ExistsByUserName(loginName)) { context.Response.Write("用户名已存在"); } else { context.Response.Write("√"); } } } #region 校验邮箱 private void CheckedUserMail(HttpContext context) { string userMail = context.Request["userMail"]; if (UserManager.ExistsByUserMail(userMail)) { context.Response.Write("邮箱已使用"); } else { context.Response.Write("√"); } } #endregion public bool IsReusable { get { return false; } } }} 另外当点击"注册"按钮后,将表单元素序列化为json数组对象
var par = $("#aspnetForm").serializeArray();
par = JSON.stringify(par);
$.post("/ashx/UserRegister.ashx", { "parameter": par }, function (data) { alert(data); });
需要在后台引用 命名空间来实现反序列化
