angularjs - Is it possible to inject into the main controller and have it be available to other controllers? Ionic -

for example, app.controller main controller.

app.controller('appcontroller', ['$scope','$ionicnavbardelegate', function ($scope,$ionicnavbardelegate) { }]); 

and second controller :

app.controller('loginpage', ['$scope','$ionicnavbardelegate', function ($scope,$ionicnavbardelegate) { }]); 

can pass $scope in main controller , have passed along loginpage controller without typing out again in loginpage controller?

yes can pass data 1 controller other using

$rootscope

for

app.controller('loginpage', ['$rootscope','$scope','$ionicnavbardelegate', function ($rootscope,$scope,$ionicnavbardelegate) {        $rootscope.items = "rootscope varibale";  }]);    app.controller('appcontroller', ['$rootscope','$scope','$ionicnavbardelegate', function ($rootscope,$scope,$ionicnavbardelegate) {  console.log($rootscope.items);  }]);
