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。
