如何在JSP中使用JSTL输出文本区域中的值

Question

我在jsp中使用JSTL，并希望在textarea

中输出值

<tr>
<th scope="row">SMS Before Inst</th>
<td colspan="7"><textarea cols="20" rows="5" placeholder="SMS Content" id=smsMessage name="smsMessage">
Time setting is
<c:choose>
<c:when test="${CTSSessionCode=='M'}">
Morning 
</c:when>
<c:when test="${CTSSessionCode=='E'}">
Everning
</c:when>
<c:otherwise>
OTHER
</c:otherwise>
</c:choose>   
Date
<c:out value="${requestDate}" ></c:out> 
,We will contact later
</textarea></td>
</tr>

内，CTSSessionCode = M是早晨，CTSSessionCode = E是晚上，requestDate是日期，但当我运行它时，它的输出是空白和空格字符。

如何解决这个问题?

Answer 1

<textarea>:

<textarea>
value
</textarea>

你可以试试:

<textarea>value</textarea>

并将<c:choose>条件移出<textarea>:

<c:set var="myVar" value="OTHER"></c:set>
<c:choose>
<c:when test="${CTSSessionCode=='M'}">
<c:set var="myVar" value="Morning"></c:set>
</c:when>
<c:when test="${CTSSessionCode=='E'}">
<c:set var="myVar" value="Everning"></c:set>
</c:when>
</c:choose>
<tr>
<th scope="row">SMS Before Inst</th>
<td colspan="7">
<textarea cols="20" rows="5" placeholder="SMS Content" id=smsMessage name="smsMessage">Time setting is ${myVar} Date ${requestDate}, We will contact later</textarea>
</td>
</tr>
