//HTML頁(yè)
只要做類似于這樣的表單
復(fù)制代碼 代碼如下:
<input id="username" type="text" onBlur="checkname()" />
<div class=d_default id=d_username>請(qǐng)輸入4位以上的英文字符或數(shù)字！</div>
<input id="Button_OK" type="button" onclick="return chk_reguser();"/>
//registerOK.ASPx.cs
復(fù)制代碼 代碼如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using BLL;
public partial class registerOK : System.Web.UI.Page
{
user user = new user();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string lb = Request["lb"];
string username = Request["username"];
string password = Request["password"];
string question = Request["question"];
string answer = Request["answer"];
string xqcode = Request["xqcode"];
string realname = Request["realname"];
string sex = Request["sex"];
string tel = Request["tel"];
string QQMSN = Request["QQMSN"];
string email = Request["email"];
string address = Request["address"];
if (lb == "checkname")
{
Response.Write(user.CheckUserName(username));
}
if (lb == "reguser")
{
string name = user.CheckUserName(username);
if (name == "恭喜，該用戶名可以注冊(cè)！")
{
user.Add(username, password, question, answer, xqcode, realname, sex, tel, QQMSN, email, address);
Response.Write("success");
}
else
{
Response.Write("fail");
}
}
}
}
}
注：registerOK.ASPx頁(yè)面必須清空所有的HTML代碼，如只剩下<%@ Page Language="C#" AutoEventWireup="true" CodeFile="registerOK.ASPx.cs" Inherits="registerOK" %>。
