這篇文章主要介紹了JSP中隱式對象用法,以實例形式分析了JSP隱式對象的定義及使用技巧,具有一定參考借鑒價值,需要的朋友可以參考下
本文實例講述了JSP中隱式對象用法。分享給大家供大家參考，具體如下：
- <%@ 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/>");
- %>
- <%
- //域之間的信息獲取
- request.setAttribute("data", "abc");//request的域
- String data=(String)pageContext.getAttribute("data", PageContext.REQUEST_SCOPE);//用pageContext域獲取Request域的內容
- out.write(data+"<br/>");
- String data2=(String)pageContext.findAttribute("data");//直接尋找data
- out.write(data2+"<br/>");
- %>
- ${data}<!-- 正則表達式 -->
- <!--
- <jsp:forward page="/1.jsp"></jsp:froward>//配置首頁時跳轉到servlet
- <jsp:include page="/1.jsp"></jsp:include><%--pageCpntext.include()動態包含--%>
- //攜帶參數
- <jsp:forward page="/1.jsp">
- <jsp:param name="data" value="data"></jsp:param>
- </jsp:froward>
- -->
- </body>
- </html>
希望本文所述對大家JSP程序設計有所幫助。
