ANGULARJS communication between controllers, event notification Service

Service to keep in mind is that all services are singleton (singleton), service is more to do some business logic, data interaction. Of course, the use of a single example of this feature can also be used to do communication between different controllers. There are several ways to communicate between controllers: How do ANGULARJS controller controllers communicate?

The way in which scope inheritance is leveraged. That is, the child controller inherits the content from the parent controller

Event-based approach. namely $on, $emit, $boardcast these three ways

Service mode. Write a single example of a service and then inject it to use

The first is somewhat limited, the second is not very convenient (or personal), and the service implements the event-based notification method.

On the Code

//provides communication to different controllersApp.factory ("EventService",function () {    varOneventfunc = {}; return{on:function(type, f) {//Event BindingsOneventfunc[type] =F; }, Trigger:function(type, data) {//Triggering Events             for(varIteminchOneventfunc) {                if(Item = =type) Oneventfunc[item] (data); }        }    }}); //UsefunctionTest1controller (EventService) {Eventservice.on ("Newmess",function(data) {//console.log (data);    });}functionTest2controller ($scope, EventService) {$scope. Send=function(data) {//Here is an example of what I used in the project when a new message was sent notifying the other controller         //triggering events, notifyingEventservice.trigger ("Newmess", data); }}

Can be based on this idea to expand the implementation of more complex business.
