ion-radio-group

单选组是 radios 组的容器。它允许用户从一组单选按钮中最多选择一个。选中属于某个单选按钮组的一个单选按钮会取消选中同一组中之前选中的任何单选按钮。有关单选框组的使用示例，请参阅 radio 文档。

¥A radio group is a container for a group of radios. It allows a user to select at most one radio button from a set. Checking one radio button that belongs to a radio group unchecks any previous checked radio button within the same group. For example usage of the radio group, see the radio documentation.
