javascript - Is it possible to call methods across controllers in Angular?

Question

I want to use the controller in the page js to call a method in a controller in the bus js. Is this possible? $rootscope is not allowed to be added, and public js is not allowed to be changed. It is said that it is not allowed to be moved in the framework. .

Answer 1

The core of angular is service, but there is no need for service. Write common methods in the service and then call them via dependency injection.

Answer 2

You can talk about your specific functional scenario. There must be something wrong with the method you use.

Answer 3

You can register a service, write the method you want in it, and then inject the service into the controller and you can call it
