我有一张地图（${userOptions}）。例如{1=B, 2=B, 3=D, 4=A, 5=D}和nxtId包含1或2或3等。
如果<c:if test="${useroption.key == nxtId}">返回成功，请检查变量value是否包含A或B或C或D.如果值为＆＃39; A＆＃39;必须检查相应的单选按钮，并且必须取消选中剩余按钮等等。
我目前正在使用以下内容：
<c:forEach var="useroption" items="${userOptions}">
<c:out value="${useroption.key == nxtId}"/>
<script>
alert("${useroption.key == nxtId}");
</script>
<c:if test="${useroption.key == nxtId}">
<c:set var="check" value="true"/>
<c:set var="value" value="${useroption.value}"/>
</c:if>
<script>
alert("check value is"+${check});
</script>
</c:forEach>
<c:choose>
<c:when test="${check eq true}">
<script>
alert("user option is "+${useroption.value});
</script>
<c:forEach var="opt" items="${questionForm}">
<c:choose>
<c:when test="${value == 'A' }">

有更好的方法吗？

您可以在不重复
之类的情况下完成此操作A. <c:out value="${opt.option1}"/><br>
<input type="radio" name="option" value="B" id="B" "${value == 'B' ? 'checked' : ''}">
B. <c:out value="${opt.option2}"/><br>
<input type="radio" name="option" value="C" id="C" "${value == 'C' ? 'checked' : ''}">
C. <c:out value="${opt.option3}"/><br>
<input type="radio" name="option" value="D" id="D" "${value == 'D' ? 'checked' : ''}" >
D. <c:out value="${opt.option4}"/><br><br>

从上面的代码中你可以实现你想要的...... 通过使用JSTL和三元运算符，您可以用更少的代码实现功能 希望它对你有所帮助
