Question

我有一个JSP代码如下。我想在输入表单中插入一个if / else循环。如果$ {experimentList.type} == GRO-seq，那么我希望值为＆＃34;正数＆＃34;和＆＃34;否定＆＃34;。否则，我希望按钮上的值显示为＆＃34; bigWig File＆＃34;和＆＃34; bigWig文件＆＃34;。我广泛搜索了这种类型的循环，但没有找到可行的解决方案。谢谢！

<c:forEach items="${experimentList}" var="experimentList">    
        <tr>
            <td>${experimentList.FGCID}</td>
            <td>${experimentList.person}</td>
            <td>${experimentList.type}</td>
            <td>${experimentList.factor}</td>
            <td>${experimentList.tissue}</td>
            <td>${experimentList.condition}</td>
            <td>${experimentList.sample}</td>
            <td>${experimentList.name}</td>
            <td>${experimentList.date}</td>
            <td>${experimentList.comments}</td>
    <form action="${pageContext.request.contextPath}/getfiles" method="post">  
            <td><input type="submit" name="track_1" value="positive" /><input type="hidden" name="track1" value="${experimentList.track1}" /></td>
            <td><input type="submit" name="track_2" value="negative" /><input type="hidden" name="track2" value="${experimentList.track2}" /></td>
    </form>

您可以将代码更新为以下

<td>
     <c:choose>
         <c:when test="${experimentList.type eq 'GRO-seq'}">
             <input type="submit" name="track_1" value="positive" />   
         </c:when>
         <c:otherwise>
             <input type="submit" name="track_1" value="bigWig File" />
         </c:otherwise>
     </c:choose>
    <input type="hidden" name="track1" value="${experimentList.track1}" />
</td>
<td>
     <c:choose>
         <c:when test="${experimentList.type eq 'GRO-seq'}">
             <input type="submit" name="track_1" value="negative" />   
         </c:when>
         <c:otherwise>
             <input type="submit" name="track_2" value="bigWig File" />
         </c:otherwise>
     </c:choose>
    <input type="hidden" name="track2" value="${experimentList.track2}" />
</td>

如果在JSP的输入标记中使用/ else循环值选项
