Question

我正在使用此代码，当我将字段集添加到我的复选框时，它就消失了。在我添加字段集之前，复选框与单选按钮一起显示正常。提前谢谢！

Answer 1

您没有关闭第二个字段集中的开始标记...

<LABEL ACCESSKEY=6<input type="checkbox" name="device" value="PC" />

注意：缺少“＆gt;”在ACCESSKEY = 6之后

 <LABEL ACCESSKEY=6><input type="checkbox" name="device" value="PC" />

我认为这应该可以解决你的问题： - ）

Answer 2

我注意到在第二个字段集中，对于Tablet和SmartPhone，输入元素后面没有结束/。请看看是否有帮助。

即。改变：

<LABEL ACCESSKEY=8<input type="checkbox" name="device" value="Tablet">Tablet</LABEL><br />
<LABEL ACCESSKEY=9<input type="checkbox" name="device" value="SmartPhone">SmartPhone</LABEL><br />

到

<LABEL ACCESSKEY=8<input type="checkbox" name="device" value="Tablet"/>Tablet</LABEL><br />
<LABEL ACCESSKEY=9<input type="checkbox" name="device" value="SmartPhone"/>SmartPhone</LABEL><br />

添加Fieldset后，复选框消失了
