Answer 1

Change: 更改：

$scope.defaultfbvalues = function () {
     fbvalues.set({
          "newspaper": '56',
          "milk": '56',
          "greens": '56'
     });
};

To: 至：

$scope.defaultfbvalues = function () {
     fbvalues.set([{
          "newspaper": '56',
          "milk": '56',
          "greens": '56'
     }]);
};

The fbvalues is array "[ ]" fbvalues是数组“ []”

Answer 2

The AngularFire $firebaseArray is built to work with typical Firebase sequences, where the keys are in the form of -J-0FSHRJ913A and usually not displayed. AngularFire $firebaseArray firebaseArray构建为与典型的Firebase序列一起使用，其中键的格式为-J-0FSHRJ913A ，通常不会显示。

In your case, you'll want to display both the $id and $value : 对于您的情况，您需要同时显示$id和$value ：

<li ng-repeat="message in syncfromfbvalues">
    {{message.$id}} - {{message.$value}}
</li>

Which displays: 显示：

greens - 56 果岭-56
milk - 56 牛奶-56
newspaper - 56 报纸-56
