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)

4.在上题的表单中增加一个checkbox,让用户选择“是否注册为会员",如果注册为会员,则在显示时增加文本“欢迎您注册为会员”。

        function lg() {
            if (form.user.value == "") {
                alert("账号不能为空!");
                return;
            }
            if (form.password.value == "") {
                alert("密码不能为空!");
                return;
            }
            if (form.validationCode.value == "") {
                alert("验证码不能为空,请输入验证码");
                form.validationCode.focus();
                return;
            }
            if (form.validationCode.value != form.validationCode1.value) {
                alert("请输入正确的验证码");
                form.validationCode.focus();
                return;
            }

            form.submit();
        }

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。

 <%
    request.setCharacterEncoding("UTF-8");
     String name=request.getParameter("name");
        int n=Integer.parseInt(name);
    for(int i=0;i<n;i++){
        out.print("欢迎"+"<br>");
   }
  
   %>
  </body>
  </html>

 

 

六、在页面1中输入账号和密码,进行登录,如果账号和密码相同,则认为成功登录到页面2,在页面2中显示一个文本框输人用户姓名,输人之后提交,在页面3中显示用户的账号和姓名。
