javascript - 如何使用 angularjs 或简单的 javascript 合并两个对象？

Question

我有两个对象

$scope.a= {"Sedan":{"Audi":["A3","A4"]},"Hatchback":{"Maruthi":["Swift"]}}; 
var b= {"Hatchback":{"Volkswagen":["Polo"],"Fiat":["Punto1"]}};

合并后需要如下结果

{"Sedan":{"Audi":["A3","A4"]},"Hatchback":{"Maruthi":["Swift"],"Volkswagen":["Polo"],"Fiat":["Punto1"]}};

Answer 1

你可以这样做..

$scope.a= {"Sedan":{"Audi":["A3","A4"]},"Hatchback":{"Maruthi":["Swift"]}}; 
var b= {"Hatchback":{"Volkswagen":["Polo"],"Fiat":["Punto1"]}};

 var mergedobj= angular.merge($scope.a, b); //merge object b into $scope.a
