这意味着该标签是针对特定的表单输入元素的: 在你的情况下，是具有id为message的文本框，或具有id为male的单选按钮。

当标签针对特定的输入元素时，单击标签的效果就像单击输入元素本身一样：单击单选按钮标签将选择单选按钮。

其中的for属性引用了</code>(message)的id。 如果您点击标签，则焦点将设置为具有相应id的<code><textarea></code>。</p> <p>您还可以使用<code><label></code>包装<code><textarea></code>。 然后，您可以单击<code><label></code>内的每个元素或文本，焦点也会设置到<code><textarea></code>。</p> </div> <div class="scisco-sq-comments"> <apcomments id="comments-106222" class="have-comments"></apcomments> </div> </div>
