1． 将“注册表单”的action设到*.jsp上，在*.jsp文件中对表单传过来的数据进行接收，并将接收到的内容显示出来。

<META NAME="Generator" CONTENT="EditPlus">
<script>
function validate()
{
var username=document.getElementById("username");
var password=document.getElementById("psw1");
var conpassword=document.getElementById("psw2");
var gender=document.getElementsByName("gender");
var interest=document.getElementsByName("hobby");
var n=0;
var comment=document.getElementById("info");
if(username.value.length<1)
{alert("用户名不能为空！");
return false;
}
if(username.value.length<4||username.value.length>10)
{alert("用户名长度应介于4-10之间！");

if(password.value!=conpassword.value)

if(!gender[0].checked&&!gender[1].checked)
{alert("性别必选其一！");
return false;
}
for(var i=0;i<interest.length;i++)
{
if(interest[i].checked)
{n++;}
}
if(n<1)

return false;

if(comment.value.length<1)

2． 创建一个Cookie对象用来保存用户名及密码，要求：在本机中可以找到该Cookie文件。
setcookie.jsp
<%@ page contentType="text/html;charset=GBK"%>
<%
Cookie c1 = new Cookie("username","mars") ;
Cookie c2 = new Cookie("userpass","www.csdn.com") ;
c1.setMaxAge(20);
c2.setMaxAge(20);
response.addCookie(c1) ;
response.addCookie(c2) ;
%>
<h1>Cookie设置成功！ </h1>
getcookie.jsp
<%@ page contentType="text/html;charset=GBK"%>
<%
// 取得全部设置的Cookie对象
Cookie c[] = request.getCookies() ;
System.out.println(c) ;
for(int i=0;i<c.length;i++){
%>
<center>
<%=c[i].getName()%>------
<%=c[i].getValue()%>
</center>
<%
}
%>
