Html制作简单而漂亮的登录页面
本文详细阐述了如何使用Html技术制作一个既简单又美观的登录页面，并提供了实用的登录登录openvas源码安装代码示例。
首先，源码源码DXF轨迹优化源码让我们先睹为快。简洁简洁
以下是登录登录Html源码和CSS代码，请复制到您的源码源码剪贴板。
总结：
具体代码如下所示：
placeholder="用户名"功能：作为占位符使用。简洁简洁
以上便是登录登录本篇文章的全部内容，希望对您的源码源码学习之路有所帮助。
ASP简单登陆注册谁有。简洁简洁颂游源码教程。登录登录。源码源码
其实学ASP学主要的是自己要去写
lysw能坚持一下午便是一个好的开始
你不要急着一下子作多么好的页面，功能多么强大的vip商业源码论坛页面
一点一点的来。
下面帮你理解一下注册和登录的原理。
Register.asp
开始不要收集太多用户信息
先从基本的用户名、密码、性别、转发看视频源码QQ号码、地址开始
用户提交页面代码省略
主要是后台处理过程：
<%
'====省略数据库连接代码====
Dim Rs,SQL
Dim Username,PWD,PWD2,Password,sex,QQ,Address
UserName=Trim(Request.form("Username")) '接受用户提交的用户名
PWD1=Trim(Request.form("PWD1")) '接受用户提交的密码
PWD2=Trim(Request.form("PWD2")) '用户名重复确认的密码
Sex=Trim(Request.form("Sex")) '接受用户提交的性别
Address=Trim(Request.form("Address")) '接受用户提交的地址
'====先对提交的信息作基本判断==========
'更多的功能比如检测Email是否正确等等
'可以以后慢慢学，先看基本原理
Dim Founderr,Errmsg
'先定义一个founderr检查是否有错;errmsg定义错在什么地方
Founderr=false '初始化founderr为flase（即解析到这里是没有错误的）
if UserName="" or Len(UserName)> then
founderr=true '发现错误
errmsg="用户名不能为空并不得大于个字符"
end if
if PWD1="" or Len(PWD1)<6 then
founderr=true '发现错误
errmsg="密码必须大于6个字符"
end if
if PWD1<>PWD2 then
founderr=true '发现错误
errmsg="两次输入的密码不正确！"
end if
if Not(ISnumeric(QQ)) or Len(QQ)<4 or Len(QQ)> then
founderr=true '发现错误
errmsg="QQ号码不正确"
end if
'性别为单选，默认有一个选中，所以不需要检验
if Address="" then
founderr=true '发现错误
errmsg="您的地址没有填写！"
end if
if founderr then '如果出现错误
Response.write Errmsg '提示错误类型
else '没有错误则
Sql="Select * from [User] where UserName='"&UserName&"'"
Set Rs=Server.CreateObject("adodb.recordset")
Rs.Open Sql,1,3 '以可写状态打开数据库
if Not(Rs.eof or rs.bof) then '如果存在该用户
Response.write Username&"已经被注册，请更换其他注册名"
else
Rs.addnew '添加纪录
Rs("Username")=username '将username插入数据库Username字段中
Rs("Password")=PWD1 '密码
Rs("QQ")=QQ
Rs("Address")=Address
Rs("Sex")=sex
Rs.update '更新数据库
Response.write UserName&"成功注册！"
end if
Set rs=nothing
end if
%>
登录页面Login.asp
用户登录页面代码省略
主要是后台处理过程：
<%
'同样从简单开始，只验证密码和用户名
'验证码以后学习完善
'====省略数据库连接代码====
Dim Rs,SQL
Dim Username,PWD
Username=Trim(Request.form("Username"))
PWD=Trim(Request.form("Password"))
Set Rs=Server.createObjcet("adodb.recordset")
'从数据库中查找用户提交的用户名和密码是否存在！
Sql="select * from [User] where Username='"&Username&"' and Password='"&PWD&"'"
Rs.open sql,conn,1,1 '只读方式打开，因为不需要更新数据库
if RS.eof or rs.bof then '如果为空，即不存在
Response.write"用户名密码错误"
else '不为空则
Session("Username")=Username '纪录用户登录信息
Response.write"登录成功"
end if
Set Rs=nothing
%>
这样一个简单的登录和注册就完成了。
