1. jsp中传递参数,经过action,存储到request中
<area shape="poly" coords="680,111,765,82,811,196,724,223"
href="${pageContext.request.contextPath}/news/queryNews.do?artType=9&new=3" alt="摄影" title="摄影" />
2. java代码中有
String newFlag=request.getParameter("newFlag");
if(newFlag!=null && !newFlag.equals("")){
request.setAttribute("newFlag",newFlag);
}
3. jsp中的类似 if - else 语句 的语法
<c:choose>
<c:when test="${requestScope.newFlag== '1' || requestScope.newFlag== '2' ||requestScope.newFlag== '3'}">
作品名称: ${star.class_}<br />
作品编号: ${star.raceNum}<br />
</c:when>
<c:otherwise>
班级: ${star.class_}<br />
参赛编号: ${star.raceNum}<br />
</c:otherwise>
</c:choose>
