3.製作一個登陸表單，輸入賬號和密碼，如果賬號密碼相同，跳轉到“登入成功”頁面，否則跳轉到“登入失敗”頁面。（加上JS非空驗證）（選做，加驗證碼）

4.在上題的表單中增加一個checkbox,讓使用者選擇“是否註冊為會員"，如果註冊為會員，則在顯示時增加文字“歡迎您註冊為會員”。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<body>
    <form action="four.jsp" method="post" name="form1">
        賬號：<input type="text" name="name"><br>
        <br> 密碼：<input type="password" name="password"><br>
        <br><input type="checkbox" name="vip" value="歡迎您註冊為會員">是否註冊為會員<br>
        <br> <input type="button" name="ti" value="提交" onclick="fu()">
    </form>
    <script type="text/javascript">
        function fu() {
            if (form1.name.value == "") {
                alert("賬號不能為空");
                return;
            }
            if (form1.password.value == "") {
                alert("密碼不能為空");
                return;
            }
            form1.submit();
        }
    </script>

        request.setCharacterEncoding("utf-8");
        String name = request.getParameter("name");
        String password = request.getParameter("password");
        String[] vip = request.getParameterValues("vip");
        if (name.equals(password)) {
        out.println("登入成功"+"<br>");
if(vip!=null){
            out.println("歡迎註冊為會員");

            out.println("登入失敗");
        }

 5.在頁面1的表單內輸人一個數字N，提交，能夠在另一個頁面列印N個“歡迎”字串。

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>歡迎</title>
</head>
<body>
    <form action="five.jsp" method="post">
        請輸入一個數字：<br>
        <br> <input type="text" name="shu"><br>
        <br> <input type="submit" name="ti" value="提交">
    </form>
</body>
</html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>歡迎</title>
</head>
<body>
    <%
        request.setCharacterEncoding("utf-8");
        String shu = request.getParameter("shu");
        double a = Double.parseDouble(shu);
        for(int i=0;i<a;i++){
         out.println("歡迎"+"</br>");
        }
    %>
</body>
</html>

 

 

 6.在頁面1中輸入賬號和密碼,進行登入，如果賬號和密碼相同，則認為成功登入到頁面2,在頁面2中顯示一個文字框輸人使用者姓名,輸人之後提交,在頁面3中顯示使用者的賬號和姓名。

        request.getRequestDispatcher("two6-1.jsp").forward(request, response);
