angular json对象push到数组中的方法

$scope.data = {
 "name":"zhangsan",
 "Menus": [{"id":1},{"id":2}]
}

 $scope.data=["name":"zhangsan"]
 $scope.selected = [1，2，3];

// 将menu数组转化为json格式
 self.convertJson = function (callback) {
  //传入数组为$scope.selected，每循环一遍就push一次
  angular.forEach($scope.selected, function (value, key) {
   $scope.data.Menus.push({
    'id':value
   });
  });
  callback($scope.data);
 };
