Detailed explanation based on the use of on-change attribute in IView

Below I will share with you a detailed explanation of the use of the on-change attribute in IView. It has a good reference value and I hope it will be helpful to everyone.

I am an android developer. Due to work needs, I have also dabbled in backend and front-end code. For the past two days, I have been troubled by the onchange in the input tag. I have been dizzy and tossing and turning. I won’t say much nonsense. Let’s talk about the problems encountered and their solutions.

The problem arises

I just studied the awesome framework of vue with my colleagues before, which realizes the three-level linkage of provincial and municipal small Function, part of the code is as follows:

   
   
   
    {{v.name}}
   
   
   
   
    {{v.name}}
   
   
   
    
    {{v.name}}
   
   
   
  

After the front-end interface is written in vue, when the front-end and back-end codes are merged into the same project, because of the js and html code The inconsistency between the specification and vue caused various problems. For example, onchange="", @change="" did not work in iview. In the end, the problem was solved through Google, a powerful search engine,

Solution to the problem

The correct way to write it in iview should be: @on-change

    
     
      
       {{v.name}}
      
     
     
      
       {{v.name}}
      
     
     
      
       {{v.name}}
      
     
    
   

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