一、基本目标 首先在Access数据库Database.mdb中存在着用户信息表test: 编写一个登陆系统,如果用户输入的用户名在表中没有,则提示“查无此人”,如果输入密码错误,则提示“密码错误” 如果用户输入的用户名与密码都正确,则跳转到登陆成功页 登陆成功页

二、基本思想

使用asp的session对象确保了用户名与密码的传递。

弹出部分使用了javascript的脚本语言

使用asp对用户信息表进行查询。

站点的基本结构如下:

三、制作过程

整个站点使用utf-8码保证不会乱码,所以每一页在页头必须有,如果使用DW的高版本则自动添加,低版本请把gb2312改成utf-8,记事本自便。

1、登陆页面login.html仅仅是一个表单的静态页面。关键是用post方法传递信息,Action是到login.asp



<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>login</title>



Copy after login
username: password:

2、login.asp登陆验证页面是本系统最核心的页面



<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>login</title>





否则在某些情况下IE8会出错
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "driver={Microsoft Access Driver (*.mdb)};pwd=admin;dbq=" & Server.MapPath(db) 
%>

<script>
alert("查无此人");
window.location.href = "login.html";
</script>

if passworddbpwd then
%>
<script>
alert("密码错误");
window.location.href = "login.html";
</script>

<script>
alert("登陆成功");
window.location.href = "success.asp";
</script>


Copy after login



3、success.asp

没什么好说的,关键是看他是否有正常登陆标志,login的内容是否为ok,没有则将其弹出登陆页面




<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>欢迎登陆</title>



"ok" then 
%>
<script>
alert("请正常登陆!");
window.location.href = "login.html";
</script>

<a href="exit.asp">正常退出</a>


Copy after login


4、exit.asp退出处理页面




<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>正在退出...</title>




<script>
window.location.href = "login.html";
</script>


Copy after login
