[angularjs] Cannot get to $rootScope

The following file "works" (the sense that it does not throw any errors):

<!doctype html>
<html ng-app="modx">
    <script src="http://code.angularjs.org/angular-1.0.0rc7.js"></script> 
    <script>
        angular.module("modx", [], function($routeProvider) {
        });
    </script>
</html>

but this

<!doctype html>
<html ng-app="modx">
    <script src="http://code.angularjs.org/angular-1.0.0rc7.js"></script>
    <script>
        angular.module("modx", [], function($routeProvider, $rootScope) {
        });
    </script>
</html>

gives the error:

Error: Unknown provider: $rootScope from modx
Source File: http://code.angularjs.org/angular-1.0.0rc7.js
Line: 2491

WTF?

This question is related to angularjs

The answer is


I don't suggest you to use syntax like you did. AngularJs lets you to have different functionalities as you want (run, config, service, factory, etc..), which are more professional.In this function you don't even have to inject that by yourself like

MainCtrl.$inject = ['$scope', '$rootScope', '$location', 'socket', ...];

you can use it, as you know.


I've found the following "pattern" to be very useful:

MainCtrl.$inject = ['$scope', '$rootScope', '$location', 'socket', ...];
function MainCtrl (scope, rootscope, location, thesocket, ...) {

where, MainCtrl is a controller. I am uncomfortable relying on the parameter names of the Controller function doing a one-for-one mimic of the instances for fear that I might change names and muck things up. I much prefer explicitly using $inject for this purpose.
