AngularJS / Firebase - Need to login twice for a successful login

问题

I have simple AngularJS app and using Firebase OpenAuth for user authentication. Here is a sample code from plunkr.

I have to click twice to authData from Google. I don't understand, why I can't get the data on the first click.

回答1:

You need to apply digest cycle after receiving an event.

$rootScope.$auth.$onAuth(function(authData){
     $rootScope.authData = authData;
     $scope.$apply();
});

Forked Plunkr
