A lot of friends learning Angular ask me about this topic (communicating between controllers). So much, in fact, that I'm writing a blog post about it.
The real answer is that there are a number of ways, but, the best practice is to keep controllers from being aware of each other as much as possible (personally, I would insist they should never be aware of each other).
The following directories include examples of each strategy. This codebase will be updated as I write the articles:
- parent-child: demonstrates Parent-Child controller communication using shared scope.
- pubsub: demonstrates using Angular's
emit,broadcast, andonfacility to communicate between components. - service: demonstrates using a third-party mechanism to synchronize state between controllers.
- router: demonstrates how to pass state via route transitions in an application.
