JSP 第一天:提交表单--获取表单中的数据值

主要用到两个内置的对象:out  和 request

out:用来在小脚本里面输出显示内容

request:用来获取用户提交的信息(包括:用户的IP,表单中的内容等)

<%@ 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 ‘index.jsp‘ starting page</title>
