Recently, I encountered a small problem. Sometimes when we use single-choice radio, we will find that when we select one, we can no longer choose one, that is, there is no cancellation function after selecting it. At this time, we think of the powerful checkbox, but it is multiple choice, how can we make it a single choice? The effect is the same as radio? This rookie wrote a mini program by himself. The code is very simple, with only four lines.
Without further ado, direct code:
The code copy is as follows:
