java关于checkbox默认选中问题.

<s:iterator value="value" id="con">
<td width="140px">
<input type="checkbox" name="dcIds" value='<s:property value="dcId"/>' <s:if test="status==1">checked="checked"</s:if>>
<s:property value="dataName"/>
</td>
</s:iterator>
想通过值栈中的status的值,来判断此复选框是否默认选中. 但是这种方法行不通.

可以的 行得通，
    <s:iterator value="value"  status="sta">
        <s:if test="#sta.dcId == 1">checked=checked</s:if>
    </s:iterator>

给你看个实际例子 <input type="radio" name="gender" value="M" <c:if test="${requestScope.employee.gender == 'M' }">checked</c:if>>Male <input type="radio" name="gender" value="F" <c:if test="${requestScope.employee.gender == 'F' }">checked</c:if>>Female <td> <select name="department.id"> <c:forEach items="${requestScope.departments }" var="department"> <option value="${department.id }" <c:if test="${requestScope.employee.department.id == department.id }">selected</c:if>> ${department.departmentName } </option> </c:forEach> </select> </td>
