javascript - Angular js same $scope in separated files -

i have angular js controller witch getting bigger , bigger, want separate functions separated files, cannot access $scope of controller in other files. best practice doing this?

for example if controller in app.js

formappcontrollers.controller('maincontroller', function($scope,$translate) {}); 

i want able use same $scope in functions.js file.

this might not answer you're looking for, i'd other way around: i'll define services , use them in controllers getting crowded. way, can avoid accessing $scope elsewhere.

something service.js have:

    var someservice = angular.module('someservice');     someservice.factory('subservice', function () {         var methodname = function (arg) {             //         }     }); 

and in angular module application logic, like:

var mainapp = angular.module('mainapp', ['someservice']); 

and ofcourse;

mainapp.controller('mainctrl', function ($scope, subservice) {     // controller stuff     subservice.methodname(arg); // etc });
