$ rootscope值在Controller中未定义

Question

我在运行中定义了一个$ rootscope对象，如此...

//Start the AngularJS App
var angularApp = angular.module('angularApp')

//Run at the start of the Angular Application
.run(function ($rootScope, $location, $firebase, $firebaseSimpleLogin) {

    //Create the User Object. 
    $rootScope.user = $firebase($rootScope.fb.child('/persons/person1'));

   //this works fine!
    console.log($rootScope.user.userId)

});

$ rootScope.user包含userId，userName，userEmail等...

后来，在一个控制器中，我想在$ rootScope.user中使用一些数据但是它未定义！

function myCtrl($rootScope, $scope) {

    //need to use $rootsope.user.userId in this command...
    $scope.folders = $firebase($rootScope.fb.child('/persons/' + $rootScope.user.userId);

    //this will display the $rootScope in the console no problem!
    console.log($rootScope);

   //this just displays 'undefined'
   console.log($rootScope.user);

};

让我疯狂的是，当myCtrl在chrome javascript控制台中显示$ rootScope时，我可以展开对象并查看用户对象!!!

但第二个console.log是未定义的。请帮忙！

您是否注入了$ firebase模块？

function myCtrl($rootScope, $scope, $firebase) {
   ...    
};
