Is there any possibility to call one controller function in another controller. I have been seeing that the data is manipulating in between controllers, but not the functions.
For Example. I have two controllers.
Module.Controller('Controller1', function($scope){ $scope.function1 = function(){}; }); Module.Controller("Controller2", function(){ // I need to call the function function1() from the controller1 }); Is this possible? Can you help me to solve this.
If you need to reuse logic from another controller, I would suggest moving that logic to a service that you can inject in both controllers. This is a much cleaner solution and is easier testable.
Example:
Module.service("Service1", function(){ this.function1 = function(){ ... } }); Module.Controller('Controller1', function($scope, Service1){ $scope.function1 = Service1.function1; }); Module.Controller("Controller2", function(Service1){ // I need to call the function function1() from the controller1 // simply call Service1.function1 here }); 
You have cannot call one function into another controller directly. But, you can change the thing in the following ways:
$rootScope.function1 instead of $scope, $rootScope is available from every $scope$rootScope.$emit to call an event from Controller2 and catch it with $rootScope.$on in Controller1 and then use the function$scope.$watch or $rootScope.$watch if the controller 2 can change some variable in the Controller1 scope, or use $rootScope.$watch unless
