我的jsp中有以下代码：
<c:forEach var="value" items="${MyList}" varStatus="loop">
<tr><td><div id="Name1">Here:${value.name}</div></td></tr>
<s:hidden id="Name" name="Name" value="%{value.name}"/>
html源代码如下：
<tr><td><div id="Name1">Here:My name is X</div></td></tr>
<input type="hidden" name="Name" value="" id="Name"/>
如图所示，div 标签正确显示了 value.name，但隐藏标签的 value 属性为空。我找不到任何解决方案，因为大多数解决方案与列表无关。我将其更改为${value.name}但遇到此错误：“根据标记文件中的 TLD 或属性指令，属性值不接受任何表达式”
我完成的JSP如下：
