关于标签的使用,急~~~~~~~~~~~~~~~~~~~
请问下在标签里如何使用el隐式对象?下面这样写为啥不对?谢谢!
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%>
<html>
<head>
<title>My JSP 'showportal.jsp' starting page</title>
</head>
<body>
<c:out value="${param.portchoice}"></c:out>
</body>
</html>
portchoice 是上一个页面的表单,单独写param.portchoice能得到表单里的数据,但放到 <c:out value="${param.portchoice}"></c:out>里就会出错,初学,请教了1
