一些常用的代码

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

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

  <div id="searchBar">

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

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

      <input type="submit" value="查询"/>&nbsp; &nbsp;&nbsp;<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
