Call a Controller angularjs in another Controller angularjs - angularjs

Question

Well my problem is I have 2 controllers... and I wanna know whether is possible call any function from them in order to do work them together...
For instance:
firstController.js
angular.module('myApp').controller('FirstController', ['$scope', 'FirstService', function($scope, FirstService) {
function verify(){
//Some operations
}
}]);
secondController.js
angular.module('myApp').controller('SecondController', ['$scope', 'SecondService', function($scope, SecondService) {
function edit(iditem){
//Some operations
//I wanna call here verify() function
}
}]);
Is this possible?
Thanks in advance!

Answer 1

You could do it with only one service and call service from both controllers. This is a basic example, you could add a constructor and pass it $scope for example it depends on what you want to accomplish.
'use strict';
/**
* Service
*/
angular.module('myApp.someService', [])
.factory("someService", function () {
return {
verify: function() {},
edit: function(iditem){
self.verify();
}
});
Then your controllers would look like this:
angular.module('myApp').controller('FirstController', ['$scope', 'someService', function($scope, someService) {
service.verify($scope);
}]);
angular.module('myApp').controller('SecondController', ['$scope', 'someService', function($scope, someService) {
service.edit(iditem);
}]);

Using Prototypical Inheritance
If the controllers are nested:
<div ng-controller="FirstController">
<div ng-controller="SecondController">
</div>
</div>
If the FirstController publishes its functions on $scope, the nested controllers can invoke the functions by prototypical inheritance.
Publish function on $scope:
app.controller('FirstController', function($scope) {
$scope.firstVerify = verify;
function verify(){
//Some operations
}
});
Invoke by $scope inheritance:
app.controller('SecondController', function($scope) {
function edit(iditem){
//Some operations
//I wanna call here verify() function
$scope.firstVerify();
}
});
This will only work if the second controller's scope is a child scope of the first controller's scope.
As you can see, there are many answers to the question. Which answer to use depends on the specific use case.

Answer 3

You can do that through $rootScope controller
include $rootScope in FirstContoller, assign a function:
$rootScope.myFirstController_verify = verify;
And call it from second controller with $rootScope included:
$rootScope.myFirstController_verify();
