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。
