本文实例讲述了JSP中隐式对象用法。分享给大家供大家参考,具体如下:
%@ 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 'demo1.jsp' starting page/title> meta http-equiv="pragma" content="no-cache"> meta http-equiv="cache-control" content="no-cache"> meta http-equiv="expires" content="0"> meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> meta http-equiv="description" content="This is my page"> !-- link rel="stylesheet" type="text/css" href="styles.css"> --> /head> body> % Date date=new Date(); out.write(date.toLocaleString()+"br/>"); %> % //域之间的信息获取 request.setAttribute("data", "abc");//request的域 String data=(String)pageContext.getAttribute("data", PageContext.REQUEST_SCOPE);//用pageContext域获取Request域的内容 out.write(data+"br/>"); String data2=(String)pageContext.findAttribute("data");//直接寻找data out.write(data2+"br/>"); %> ${data}!-- 正则表达式 --> !-- jsp:forward page="/1.jsp">/jsp:froward>//配置首页时跳转到servlet jsp:include page="/1.jsp">/jsp:include>%--pageCpntext.include()动态包含--%> //携带参数 jsp:forward page="/1.jsp"> jsp:param name="data" value="data">/jsp:param> /jsp:froward> --> /body> /html>
希望本文所述对大家JSP程序设计有所帮助。
