如何从JSON数据合并两个不同的对象

嗨，我需要一些有关此代码段的帮助。我得到的输出是JSON数据的多个不同对象。但是我想提取目标数据，然后将它们合并为一个数组。但是我得到的所有数据仅仅是一个数据被一个数组一个接一个地合并。这是输出：

$scope.findHospital = function(){

    $ionicLoading.show({
        template: '<ion-spinner icon="bubbles"></ion-spinner><br/>Acquiring location!'
    });

    var posOptions = {
        enableHighAccuracy: true,
        timeout: 20000,
        maximumAge: 0
    };

    $cordovaGeolocation.getCurrentPosition(posOptions).then(function (position) {
        var lat  = position.coords.latitude;
        var long = position.coords.longitude;
        var infowindow;

        var myLatlng = new google.maps.LatLng(lat, long);

        var mapOptions = {
            center: myLatlng,
            zoom: 16,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

        var map = new google.maps.Map(document.getElementById("map"), mapOptions);
        infowindow = new google.maps.InfoWindow();

        var service = new google.maps.places.PlacesService(map);
        service.nearbySearch({
            location: myLatlng,
            radius: 5000,
            type: ['police']
        }, callback);

        function callback(results, status) {
            if (status === google.maps.places.PlacesServiceStatus.OK) {
                for (var i = 0; i < results.length; i++) {
                    createMarker(results[i]);
                }
            }
        }

        function createMarker(place) {
            geocoder = new google.maps.Geocoder();

            var latlng = new google.maps.LatLng(lat, long);
            geocoder.geocode({'latLng': latlng}, function(results, status) {
                var placeLoc = place.geometry.location;
                var marker = new google.maps.Marker({
                  map: map,
                  position: place.geometry.location
                });
                var request = { reference: place.reference };

                service.getDetails(request, function(details, status) {
                    console.log(details);

                    var url = "https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins="+results[0].formatted_address+"&destinations="+details.formatted_address+"&key=AIzaSyDDxMGpu5SP5XwZGrKw5BQWl_r2dgLgpPY";
                    var distances = [];

                    $http.get(url).then(function(response){
                        var str = response.data.rows[0].elements[0].distance.text;

                        distances = distances.concat(str);

                        console.log(distances);
                    });
                }
            });
        }
    }
}
