任务二、教材P45 8题
提示:圆形面积需要一个param 梯形面积需要3个param,可以参考教材例2-11

任务三、
1.应用表格对页面进行布局(可以借助于Dreamweaver 制作页面框架),如下图所示。表格中显示的文件内容为使用include指令引入相应的JSP文件(JSP文件的内容不限)。
<%@ 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> <base href="<%=basePath%>"> <title>My JSP 'index1.jsp' starting page</title> </head> <body > <table border="1" width="600" align="center" bgcolor="green"> <tr align="center"><td colspan="2"><%@include file="top.jsp" %></td></tr> <tr align="center"><td><%@include file="left.jsp" %></td><td align="center"><%@include file="right.jsp" %></td></tr> <tr align="center"><td colspan="2"><%@include file="end.jsp" %></td></tr> </table> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="left.jsp"%> <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="right.jsp"%> <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="top.jsp"%> <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="end.jsp"%>
任务四
编写一个JSP文件,在该文件中,应用Math.round(Math.random()*10)生成[0,10]之间的随机整数,然后根据生成的是偶数还是奇数,应用<jsp:forward>动作标记分别跳转到对应的偶数页面和奇数页面。
<%@ 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> <base href="<%=basePath%>"> <title>My JSP 'index1.jsp' starting page</title> </head> <body> <% String r=request.getParameter("i"); int x=Integer.parseInt(r); %> Hello,我是可可爱爱的偶数!!! </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> <base href="<%=basePath%>"> <title>My JSP 'index1.jsp' starting page</title> </head> <body> <% String r=request.getParameter("i"); int x=Integer.parseInt(r); %> Hello,我是一个奇奇怪怪怪的奇数!!! </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> <base href="<%=basePath%>"> <title>My JSP 'index1.jsp' starting page</title> </head> <body> <% int i = (int) (Math.random() * 10 + 1); if (i % 2 == 0) { %> <jsp:forward page="oushu.jsp"> <jsp:param value="<%=i %>" name="i" /> </jsp:forward> <% } else { %> <jsp:forward page="jishu.jsp"> <jsp:param value="<%=i %>" name="i" /> </jsp:forward> <% } %> </body> </html>
