javascript - angularjs custom $error

Question

I want to customize the request $error, and return the name of $error according to the interface request to determine the corresponding prompt for ng-show prompts to the user:
For example: regForm.$error.isWrong

Answer 1

I don’t understand why $error needs to be redefined.
Wouldn’t it be better if you process the $error returned by the interface, convert it into the desired format, and then implement two-way binding on the page?
