How to correctly use this in mixins when working with a class?

Question

JavaScript

I understand how vuejs works, I try to combine the class and mixins. I want to understand how to use the common dataand func- functions. When calling the function, it throws an error:

Uncaught TypeError: Cannot read property 'test1' of undefined"

I understand that he does not find 'test1',it; the function is a nested object, so there is no access to the parent this. How to fix it?

Answer 1

Bind the context in advance ( bind ), or specify it when calling ( call , apply ).

Understanding how vuejs works

vue bind context ahead of time
