如何判断空：<c:if test="${orderform.name !=null}">
<td align="center" width="20%"> <c:choose><c:when test="${ empty news.issueNo}"></c:when><c:otherwise> <span style="font-size:15px">issue : ${news.issueNo }</span></c:otherwise> </c:choose></td><c:set var="log.logTitle" value="做一个截取字符串长度的测试"<c:choose><c:when test="${fn:length(log.logTitle) > 10}"> <c:out value="${fn:substring(log.logTitle, 0, 10)}" /></c:when><c:otherwise> <c:out value="${log.logTitle}" /></c:otherwise></c:choose>
<body> <% Set hashSet = new java.util.HashSet(); hashSet.add(1111); hashSet.add(222);request.getSession().setAttribute("set",hashSet); %> <script> alert(${fn:length(sessionScope.set)}); </script></body>
