jsp里面传值的问题
<%@taglib uri= "http://java.sun.com/jsp/jstl/core " prefix= "c " %>
<%request.setParameter( "user ", "x ");
%>
<c:if test= " <%= request.getParameter( "user ") != null%> ">
hello, <%= request.getParameter( "user ")%>
</c:if>
我想输出结果是 hello,x
这样传值怎么不行,应该怎么写,谢谢
[解决办法]
<%if (request.getParameter( "user ") != null)%>
hello, <%= request.getParameter( "user ")%>
[解决办法]
request.setAttribute( "user ", "x ");
在 <body> 里
hello, <%=request.getAttribute( "user ") %>
