提问by Nachiket Kamat
Is there any way to use a radio button and make it hidden as well?
有没有办法使用单选按钮并将其隐藏？

See HTML Forms: Control Typesfor:
请参阅HTML 表单：控件类型：
hidden controlsAuthors may create controls that are not rendered but whose values are submitted with a form. Authors generally use this control type to store information between client/server exchanges that would otherwise be lost due to the stateless nature of HTTP (see [RFC2616]). The
INPUTelement is used to create a hidden control.
隐藏控件作者可以创建不呈现但其值随表单提交的控件。作者通常使用这种控制类型来存储客户端/服务器交换之间的信息，否则这些信息会因 HTTP 的无状态性质而丢失（参见 [RFC2616]）。该
INPUT元素用于创建隐藏控件。

You can hide a radio button by using the set.Visible(Boolean flag) method from javax.swing:
您可以使用 javax.swing 中的 set.Visible(Boolean flag) 方法隐藏单选按钮：
myButton.setVisible (false);
myButton.setVisible (false);

You should avoid using display:noneor visibility:hiddenon form field elements because this will have a negative impact on accessibility. Users who are navigating your website via the keyboard (no mouse) will not be able to tab between form elements and check/uncheck them. You could try using the following instead:
您应该避免在表单字段元素上使用display:none或visibility:hidden，因为这会对可访问性产生负面影响。通过键盘（无鼠标）浏览您的网站的用户将无法在表单元素之间切换以及选中/取消选中它们。您可以尝试使用以下方法：
-moz-appearance: none;
-webkit-appearance: none;
appearance: none;
Update:Due to a known bug in Firefox, the radio button's border and dot are still visible when appearance: nonehas been applied. Setting the opacity to zero instead seems to be working for me:
更新：由于Firefox 中的一个已知错误，应用后单选按钮的边框和点仍然可见appearance: none。将不透明度设置为零似乎对我有用：
opacity: 0;
