Angularjs call a function from a controller to another controller

Question

I'm trying since few hours to call a function from a controller to another controller.

I saw similar topics (I tried but I'm certainly too bad): What's the correct way to communicate between controllers in AngularJS? Can one controller call another?

But no concrete example like I'm looking for.

Controllers:

app.controller('Controller1', function($scope, $modal, $modalInstance, job, JobServices) {
 $scope.job1 = function () {
 JobServices.job1($scope.name)
 .success(function(data, status, headers, config) {
 // something
 });
 }
 function doSomething(){
 // How call test() from controller2 ?
 }
}
app.controller('Controller2', function($scope){
 function test(){
 do a lot of things
 }
}

What's the best and easiest way to do that ?

Thank you a lot

EDIT:

I already tried using something like that:

app.controller('Controller1', ['$scope', '$rootScope', function($scope, $rootScope, $modal, $modalInstance, job, JobServices) {

But I have error saying job1 is undefined...

• Aleksey Solovey: You probably want to put your logic into a service/factory and call the function on it instead.
• Sajal: Possible duplicate of $on and $broadcast in angular
• C.Norris: My problem is I have a lot of errors when I use function($scope, $modal, $modalInstance, job, JobServices) to ['$scope', '$rootscope', function($scope, $rootscope, $modal, $modalInstance, job, JobServices) from my functions like job1 (see my edit)

Answer 1

you could the $scope.$emit and $scope.$on, little bit like this

app.controller('Controller1', ['$scope', '$rootScope' function($scope) {
 function doSomething(){
 $rootScope.$emit("callController2", {});
 }
}
app.controller('Controller2', ['$scope', '$rootScope' function($scope) {
 $rootScope.$on("callController2", function(){
 this.test();
 });
 function test(){
 do a lot of things
 }
}

• C.Norris: As I said upper I already tried that and I have error (saying it's undefined) using ['$scope', '$rootScope'... (see my edit)
