javascript - Using Angular services to hold commonly required data -


i writing first application in angular , have been enjoying framework has offer far. newbies set off building main controller, copying tutorials. seeing error of ways , refactoring.

my question services holding data commonly required among controllers.

i've taken data out of 'main controller' , placed service have injected both controllers requiring access. though neither controller sees functionality i've defined in new service:

varianceservice not defined

being new approach welcome , help, aswell current problem, comments on best way apply approach highly appreciated.

thanks in advance.

here example of code:

var app = angular.module(     'varianceanalysis', ['ngroute', 'nganimate', 'mgcrea.ngstrap', 'mgcrea.ngstrap.tooltip', 'mgcrea.ngstrap.helpers.dateparser', 'sharedservices']     )     .service('varianceservice', function () {         var variances = {};         return {             redirect: function (path) {                 $location.path(path);             },             gethttpvariances: function (month1, month2) {                 var url = "/home/getvariances?month_1=";                 url += month1;                 url += "&month_2="                 url += month2;                 url += "&forwardbilling=true"                  $http.get(url).success(function (data) {                     variances = data;                     return data;                 });                 return {};             },             getvariances: function () {                 return variances;             }         };     })     .config(['$routeprovider',       function ($routeprovider) {           $routeprovider.               when('/mainpage', {                   templateurl: 'mainpage.html',                   controller: 'mainpagectrl'               }).               when('/variance/:type', {                   templateurl: 'variance.html',                   controller: 'variancectrl'               }).               otherwise({                   redirectto: '/mainpage'               });       }])     .controller('variancectrl', ['$scope', 'varianceservice', function ($scope, $http, $location, $routeparams) {         $scope.variance_type = varianceservice.getvariances();     }])     .controller('mainpagectrl', ['$scope', 'varianceservice', function ($scope, $http, $location) {         $scope.go = function (month1, month 2) {         $scope.variances = varianceservice.gethttpvariances(month1, month2);     }]);

change this

.controller('variancectrl', ['$scope', 'varianceservice', function ($scope, $http, $location, $routeparams) {     $scope.variance_type = varianceservice.getvariances(); }])

to

.controller('variancectrl', ['$scope', '$http', '$location', '$routeparams', 'varianceservice', function ($scope, $http, $location, $routeparams, varianceservice) {     $scope.variance_type = varianceservice.getvariances(); }])
