JSP中隐式对象用法实例
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:
<%@pagelanguage="java"import="java.util.*"pageEncoding="UTF-8"%> <% Stringpath=request.getContextPath(); StringbasePath=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN"> <html> <head> <basehref="<%=basePath%>"> <title>MyJSP'demo1.jsp'startingpage</title> <metahttp-equiv="pragma"content="no-cache"> <metahttp-equiv="cache-control"content="no-cache"> <metahttp-equiv="expires"content="0"> <metahttp-equiv="keywords"content="keyword1,keyword2,keyword3"> <metahttp-equiv="description"content="Thisismypage"> <!-- <linkrel="stylesheet"type="text/css"href="styles.css"> --> </head> <body> <% Datedate=newDate(); out.write(date.toLocaleString()+"<br/>"); %> <% //域之间的信息获取 request.setAttribute("data","abc");//request的域 Stringdata=(String)pageContext.getAttribute("data",PageContext.REQUEST_SCOPE);//用pageContext域获取Request域的内容 out.write(data+"<br/>"); Stringdata2=(String)pageContext.findAttribute("data");//直接寻找data out.write(data2+"<br/>"); %> ${data}<!--正则表达式--> <!-- <jsp:forwardpage="/1.jsp"></jsp:froward>//配置首页时跳转到servlet <jsp:includepage="/1.jsp"></jsp:include><%--pageCpntext.include()动态包含--%> //携带参数 <jsp:forwardpage="/1.jsp"> <jsp:paramname="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。
