2、javascript+CSS+Html实现用户注册及登录的注册注册格式验证。在用户登录功能中试加入验证码功能
下面是用户源码用户源码线程操作模块源码关键代码，如果剩下的注册注册java string源码解析你都搞不懂，我就无语了
JS
<script type="text/javascript" language="javascript">
function reloadcodeOne(){ //刷新验证码函数
var verify = document.getElementById('checkCodeImg');
verify.setAttribute('src',用户源码用户源码 'validateCode?dt=' + Math.random());
}
<script type="text/javascript" >
html
<p>
<label>验证码：</label>
<input class="code" value="请输入验证码" title="请输入验证码" name="rendCode" id="rendCode" onfocus="if (value =='请输入验证码'){ value =''}" onblur="if (value ==''){ value='请输入验证码'}" type="text" size="6" />
<span><img id="checkCodeImg" src="validateCodeServlet" onclick="javascript:reloadcodeOne();" alt="" width="" height="" /></span>
</p>

如何用XML和ASP结合做一个用户注册模块
下面是html部分的代码：
<html>
<body>
<link= "...path/***.asp"><!--这里些的是你的asp
文件的存放地址-->
<form>
姓名：
<input type="text" name="Name">
<br>
密码：
<input type="text" name="Passeword">
<input type="submit" value="提交">
</form>
</body>
</html>
下面是asp文件代码：
dim fname
fname=Request.QueryString("fname")
If fname<>"" Then
Response.Write(fname & "<br />")
Response.Write("欢迎来到POP！")
注册注册End If
注册注册
