3.8web网页设计的一篇作业

我今天学习了如何从一个网页跳转到另一个网页，首先我做了第一个页面Homework，在这个页面运行后会出现一个输入数字的文本框，再点击提交后，会跳转到另一个页面并比较与你指定数比较大小

第一个网页：Homework

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

<%

String path = request.getContextPath();

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

%>

 

  

    "<%=basePath%>">

    

    

    

"pragma" content="no-cache">

"cache-control" content="no-cache">

"expires" content="0">    

"keywords" content="keyword1,keyword2,keyword3">

"description" content="This is my page">

 

  

  

  

    "forml"method="post"action="answer.jsp">

     数字:

     

        "test" name="number"id="textfield">

        

        "submit"name="button"id="button"value="提交">

     

    

  

 

第二个网页：Answer

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>

<%

String path = request.getContextPath();

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

%>

<%String Num  ; %>

  

    "<%=basePath%>">

    

    

    

"pragma" content="no-cache">

"cache-control" content="no-cache">

"expires" content="0">    

"keywords" content="keyword1,keyword2,keyword3">

"description" content="This is my page">

 

  

  

  

    

    <% Num = request.getParameter("number"); %>

    <%

    Integer.valueOf(Num);

    if(Integer.valueOf(Num)>=10) {

        %>

        <%=+Integer.valueOf(Num)+">=10" %>

        <%

     }else{

         %>

        <%=+Integer.valueOf(Num)+"<10" %>

        <%

        }

      %>
