1 选择分支
<!--非此即彼 分支--> <c:choose> <c:when test="${empty royalties}"> 0.00</c:when> <c:otherwise>${royalties }</c:otherwise> </c:choose>
2 判断
<!--判断--> <c:if test="${a.loginType==1 }">在线 </c:if> <c:if test="${a.loginType==0 }"> <font color="blue">离线</font> </c:if>
3. 三目运算
<!--下拉列表(查询条件记忆)--> <select name="transType" id="transType"> <option value="" ${shopCar.transType==null?‘selected=\"selected\"‘:‘‘ }>请选择</option> <option value="1" ${shopCar.transType==1?‘selected=\"selected\"‘:‘‘ }>到付</option> <option value="2" ${shopCar.transType==2?‘selected=\"selected\"‘:‘‘ }>免邮费</option> </select>
<!--溢出字符自动截断 --> <td> ${fn:length(pr.req_remark)>21 ? fn:substring(pr.req_remark,0,21) : pr.req_remark} ${fn:length(pr.req_remark)>21 ? ‘...‘ : ‘‘ } </td>
溢出截断也可以用<c:if>这么写:
<c:if test="${fn:length(article.title)>21"}>${fn:substring(article.title,0,21)}....</c:if> <c:if test="${fn:length(article.title)<=21"}>${article.title}</c:if>
