About two-way binding of parent component and child component in Vue2.x (detailed tutorial)

This article mainly introduces how to solve the two-way binding problem between Vue2. I am using UI components for my own use. To improve my BIG, I encountered a problem when making a component containing input: I don’t know how to achieve two-way binding between the input in the sub-component and the data of the caller (parent component). I thought about using Vuex, but I didn’t know how to use it. After looking at other excellent UI frameworks, I found that using Vuex would cause trouble to other users, so I decided to find a solution. After referring to several articles by experts, I finally found it.

I post the solution here, hoping to help colleagues like me who are coming into contact with the Vue framework for the first time.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
