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。
