JavaWeb第三次作业

任务一、教材P39实验3

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

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
 <%!double r=(int)(Math.random()*10)+1; %>
<jsp:include page="circle.jsp">
<jsp:param name="r" value="2"/>
</jsp:include>
<br>
<jsp:include page="ladder.jsp">
<jsp:param name="s" value="3"/>
<jsp:param name="x" value="4"/>
<jsp:param name="g" value="7"/>
</jsp:include>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

     <%!double getarea(double s,double x,double g){
           double area=(s+x)*g/2;
           return area;
   } %>
   <%
   String string=request.getParameter("s");
   double s1=Double.parseDouble(string);
   string=request.getParameter("x");
   double x1=Double.parseDouble(string);
   string=request.getParameter("g");
   double g1=Double.parseDouble(string);
   double area=getarea(s1, x1, g1);
   
   out.print("梯形的上底是"+s1+"下底是"+x1+"高是"+g1+"面积是"+area);
    %>
   
  </body>
</html>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

  <body>
    <%!double getarea(double r){
           double area=3.14*r*r;
           return area;
   } %>
   <%
   String r=request.getParameter("r");
   double r1=Double.parseDouble(r);
   double area=getarea(r1);
   out.print("圆形的半径是"+r+",圆形的面积："+area);
    %>
  </body>
</html>

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>
