一些常用的代码

<c:if test="${empty currAccount}" var="flag"><a href="${ctx}/login.jsp">登录</a>  |  </c:if>

<c:if test="${!flag}"><a href="${ctx}/account.do?method=logout">注销</a>  |   </c:if>







<div id="searchBar">

<form id="searchForm" name="searchForm" action="${ctx}/forumupload.do?method=search" method="post">文件搜索：  

<input type="text" name="keyword" size="40" maxlength="50" value="${param.keyword}"/>  

<input type="submit" value="查询"/>    <a href="#">高级搜索</a>

</form>

</div>







<div class="longBar">

<div class="longTitle">搜索结果：搜索关键字【${lsr.keyword}】，共搜索到【${lsr.recordCount }】个产品，耗时：${lsr.time}秒，当前显示${lsr.stratNo}—${lsr.endNo}记录</div>

<div class="longBody">

<form action="${ctx}/account.do?method=login" method="post" onsubmit="return submitForm();">

<table width="100%" border="0" cellspacing="5" cellpadding="5">

<c:forEach items="${lsr.datas}" var="prod">

<tr>

<td>

产品名: <a href="${ctx}/prod.do?method=findById&id=${prod.id}">${prod.name}</a><br/>

产品描述：${prod.description}<br/>

出产日期： ${prod.pubDate }<br/><hr/>

</td>

</tr>

</c:forEach>

</table>

</form>

</div>





<c:choose>
<c:when test="${fn:length(Article.summary)<=20}">
${Article.summary }
</c:when>
<c:otherwise>
${fn:substring(Article.summary,0,20)}……
</c:otherwise>
</c:choose>





以下输出为：列表所有权限，当前角色拥有的角色选中
