这是我尝试过的方法，我只需要从任一服务中选择一个单选按钮。如果选择了一个包中的一项服务，则不应选择其他包服务。我还有 6 个其他包用户应该能够一次从这些不同的包集中选择一个请帮忙。时间差

因为名称相同，所以我在输入和名称上绑定(bind)了事件处理程序。

不知道你有没有用jQuery

为方便起见，我在下面使用 jQuery 进行了此操作。

我唯一做的就是添加事件处理程序。

$('input[name="service"]').click(function(event){
   $('input[name="service"]:checked').not(this).prop('checked', false);
})
