添加JSON对象在AngularJS

Question

所以我拉一些JSON使用此

$http.get('/balance').then(function (response) { 
    $scope.balance = response.data; 
}); 

和response.data AngularJS是这样

{ 
    "pending": [{ 
    "amount": 16, 
    "currency": "usd" 
    }], 
    "available": [{ 
    "amount": 20, 
    "currency": "usd" 
    }], 
    "livemode": false, 
    "object": "balance" 
} 

如何添加两个“量”到一起，并设置他们等于Angular中的变量？所以对于这个变量应该设置为16+20？

Answer 1

$scope.newProp = response.data.pending[0].amount + response.data.available[0].amount;
