我已经使用jstl在found.jsp上显示来自表名为status(所有列都是字符串类型)的特定数据。在我的表中,我在状态列下输入了1和0,其中1表示IN,0表示OUT。
found.jsp

下面是
下显示1和0的列 <th>File Status(IN=1 and OUT=0)</th>
<th>File Department</th>
<th>Date and Time</th>
</tr>
<c:forEach var="row" items="${result.rows}">
<tr>
<td><c:out value="${row.fname}"/></td>
值来自这里
<td><c:out value="${row.fstatus}"/></td>
<td><c:out value="${row.department}"/></td>
<td><c:out value="${row.datetime}"/></td>
</tr>

我不希望显示1和0,而是希望IN和OUT显示在列下,我不想将数据库表entery从1和0更改为IN和OUT有没有办法可以做到这一点?
答案 0 :(得分:1)
您可以使用<c:choose>
代码
<c:choose>
<c:when test="${row.fstatus=='1'}">
IN
</c:when>
<c:otherwise>
OUT
</c:otherwise>
</c:choose>
