 3.制作一个登陆表单,输入账号和密码,如果账号密码相同,跳转到“登录成功”页面,否则跳转到“登录失败”页面。(加上JS非空验证)(选做,加验证码)

<% String account=request.getParameter("account");
String password=request.getParameter("password");
if(account.equals(password)){
response.sendRedirect("welcome.jsp");
}else{

}%>
  </body>
</html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

  <body>
<% String account=request.getParameter("account");
String password=request.getParameter("password");
String huiyuan=request.getParameter("huiyuan");

if(account.equals(password)){
out.print("注册成功");
 }else if(account.equals(password)&&huiyuan.equals("yes"))
       {out.print("欢迎您成为会员!");
       }else if(account.equals(password)&&huiyuan.equals("no")) {
out.print("没有成为会员"); 
}else{
out.print("登录错误");}
%>
  </body>
</html>

 

 

 

5.在页面1的表单内输人一个数字N,提交,能够在另一个页面打印N个“欢迎”字符串。

<html>
  <head>

  </head>
  
<body>
    <%
    String shu=request.getParameter("shu");
    int n=Integer.parseInt(shu); 
    for(int i=0;i<n;i++){
    out.print("欢迎"+"!! ");
