AngularJS TypeError: Cannot call method 'apply' of undefined

Question

I get this error in AngularJS:

TypeError: Cannot call method 'apply' of undefined

When calling this line of code in my controller:

function ClientController($scope, $routeParams, $location, StaticData, Client, IndustryFactory) {
     $scope.$on('$viewContentLoaded', someMethod);
}

Tried below which also doesn't help, same error:

ClientController.$inject = ['$scope', '$routeParams', '$location', 'StaticData', 'Client', 'IndustryFactory'];

Answer 1

You need to include $scope explicitly in your controller like this to make it work.

function ClientController($scope, $routeParams, $location, StaticData, Client, IndustryFactory) {
     $scope.$on('$viewContentLoaded', someMethod);
}


ClientController.$inject = ['$scope', '$routeParams', '$location'];

Answer 2

Figured it out. See revised code:

$scope.$on('$viewContentLoaded', function() { someMethod() });

Answer 3

This i believe is issue with minification of your code. Either inject the dependencies as described by @jayaram or use the the [] notation for dependencies and using modules. See the section Notes on Minification here
