javascript - How to call a function from another module

Question

In my angularJS application, I have two modules : module A and module B.

angular.module('A').controller('ACtrl',function($scope){
    $scope.alertA = function(){alert('a');}
    //...
});

angular.module('B').controller('BCtrl',function($scope){
    //...
});

How to call the function alertA in the module B ?

You need to define a factory in module A:

var moduleA= angular.module('A',[]);
moduleA.factory('factoryA', function() {
    return {
        alertA: function() {
            alert('a');
        }    
    };
});

Then use the alertA factory in module B:

angular.module('B',['A']).controller('BCtrl',function($scope,'factoryA'){
    factoryA.alertA();
});
