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>
