Is it possible to get the value of a variable from a directive in a controller?

Question

Angular

Good afternoon!
The scope.directiveVar variable is declared in the directive. In the controller, I need to get the value of this variable. A directive from a third-party module that is injected as a dependency to the main application module. Is it possible to do so?

Answer 1

It is best to use the pub/sub pattern in this case.
Angular uses $broadcast , $emit , $on functions for this .
Here's a good article about the difference between broadcast and emit and how it works in general: toddmotto.com/all-about-angulars-emit-broadcast-on...

Answer 2

In the directive, there are "operators" = and & (in scope) for this. But if the directive is not provided, then it will have to be edited.
You can also do a dirty hack - climb into child scopes and take a variable from there (or subscribe to it).
