<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body bgcolor=#ffccff> <% double price=98.78; %> <p style="font-family:宋体;font-size:36;color:blue"> 商品价格A1001，价格8765 <a href="example4_9_receive.jsp?id=A1001&price=8765">购买</a><br> 商品价格A1002，价格<%=price %> <a href="example4_9_receive.jsp?id=A1002&price=<%=price %>">购买</a> </p> </body> </html>

2.教材P97 实验2
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <h1>我的计算器</h1> <hr> <head> <!-- 在jsp里面添加js内容 --> <script type="text/javascript" > function onClickCheck(){ if(document.form1.num1.value==""||document.form1.num2.value==""){ window.alert("该文本框里面的内容不能为空!!"); return false; } if(Math.round(document.form1.num1.value)!=document.form1.num1.value||Math.round(document.form1.num2.value)!=document.form1.num2.value){ window.alert("输入的字符非法!!"); return false; } } </script> </head> <body> <form name="form1" action = "myResult.jsp" > 请输入第一个数：<input type = "text" name = "num1"><br> <select name="flag"> <option value=+>+</option> <option value=->-</option> <option value=*>*</option> <option value=/>/</option> </select><br> 请输入第二个数：<input type="text" name = "num2"><br> <input type = "submit" value = "计算" οnclick="return onClickCheck();"> </form><br> <hr> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <html> <body> <% //接受第一个数 String num1_get = request.getParameter("num1"); //接受第二个数 String num2_get = request.getParameter("num2"); //接受运算符号 String flag = request.getParameter("flag"); //计算 int num1=0; int num2=0; int result=0; num1=Integer.parseInt(num1_get); num2=Integer.parseInt(num2_get); if(flag.equals("+")){ result=num1+num2; } else if(flag.equals("-")){ result=num1-num2; } else if(flag.equals("*")){ result=num1*num2; } else{ result=num1/num2; } out.println("结果为:"+result); //输出结果 %> </body> </html>
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）
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body> <form action=manager.jsp name=form1 method=post></form> <input type="text" name=name> <input type="password" name=password> <input type="submit" value="登录" name="submit"> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body> <% request.setCharacterEncoding("utf-8"); String name=request.getParameter("name"); String password=request.getParameter("password"); if (name.equals(password)) request.getRequestDispatcher("success.jsp").forward(request, response); else request.getRequestDispatcher("error.jsp").forward(request, response); %> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body> 登录成功 </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body> 登录失败 </body> </html>
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”。
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body> <form action=manager.jsp name=form1 method=post></form> <input type="text" name=name> <input type="password" name=password> 是否注册为会员：<input type="checkbox" name="member" value="注册">注册 <input type="checkbox" name="member" value="不注册">不注册<br> <input type="submit" value="登录" name="submit"> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body> 登录成功 欢迎您注册为会员！ </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。
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body> <form action="second.jsp" method="post"> <p style="font-family:宋体;font-size:18;color:black"> 请输入数字：<input type="text" name="number" size=10><br> <br> <input type="submit" name="submit" value="提交"> </form> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head></head> <body bgcolor=#EEEEFF> <% request.setCharacterEncoding("utf-8"); String number = request.getParameter("number"); int a = Integer.parseInt(number); for (int i = 0; i < a; i++) { out.print("欢迎" + "<br>"); } %> </body> </html>
