Question

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.
