You interrupt point to look at, I feel more than once, whether the button is not contained in the Group

refer to 7th floor zhang106209 response:

If not included in the Gruop should also perform not for the first time, but this can perform at a time

CodePudding user response:

1. Did your radiobutton accidentally set the click event, if set please delete
2. You click on all the rb is a trigger for the first time?
3. The first time when triggered, click other rv selected will change?
