Angular $rootScope.$on Undefined

Question

I have the following in a controller.

$rootScope.$on(\'progressbarEvent\', function (event, data) {
    $rootScope.progresscurrent = data.currentprogress;
           


        

Answer 1

The order of dependencies has to be consistent with the array it was declared in:

app.controller('indexcontroller', ['$rootScope','$scope', '$http', 'dataFactory',
   function ($rootScope, $scope, $http, dataFactory) {
