在控制器未定义$ rootscope价值 [英] $rootscope value undefined in Controller

问题描述

我在运行中定义，像这样一个$ rootscope对象。

I have a $rootscope object defined in the run like so..

//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持有用户id，用户名，USEREMAIL，等等...

$rootScope.user holds userId, userName, userEmail, etc...

后来，在控制器，我想用在$ rootScope.user但其不确定的一些数据！

Later, in a controller, I want to use some data in $rootScope.user but its undefined!

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);

};

什么是让我疯狂的是，当myCtrl显示$ rootScope铬的JavaScript控制台，我可以扩大对象，并看到用户对象！

What is driving me insane is that when myCtrl displays the $rootScope in chrome javascript console, I can expand the object and SEE the user object!!!

但第二的console.log仅仅是不确定的。请大家帮忙！

But the second console.log is just undefined. please help!

推荐答案

你注入$火力模块？

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