添加JSON對象在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是這樣

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

如何添加兩個「量」到一起，並設置他們等於Angular中的變量？所以對於這個變量應該設置爲16+20？

Answer 1

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