Question

我有来自外部API的数据，我想在我的GoogleMap中对标记进行分组。我使用的是NgMap指令：

ng-map center="[21.18, 27.71]" style='margin: 10px 0; height: 500px;' zoom='6'
        marker position="{{item.latitude}}, {{item.longitude}}" ng-repeat="item in items"

那么如何在AngularJS（1.5x）控制器中设置MarkerClusterer。 https://jsfiddle.net/7nqg7f7f/6/ - ＆gt;我是这样做的。

ng-map库涵盖Google Maps API，相反，MarkerClusterer是Google Maps JavaScript API v3的单独库，ng-map不支持（至少在目前）

以下示例演示了如何将MarkerClusterer与ng-map一起使用：

angular.module('mapApp', ['ngMap'])
    .controller('mapController', function ($scope, NgMap) {

        NgMap.getMap().then(function (map) {
            $scope.map = map;
            $scope.initMarkerClusterer();
        });

        $scope.cities = [
            { id: 1, name: 'Oslo', pos: [59.923043, 10.752839] },
            { id: 2, name: 'Stockholm', pos: [59.339025, 18.065818] },
            { id: 3, name: 'Copenhagen', pos: [55.675507, 12.574227] },
            { id: 4, name: 'Berlin', pos: [52.521248, 13.399038] },
            { id: 5, name: 'Paris', pos: [48.856127, 2.346525] }
        ];
        


        $scope.initMarkerClusterer = function () {
            var markers = $scope.cities.map(function (city) {
                return $scope.createMarkerForCity(city);
            });
            var mcOptions = { imagePath: 'https://cdn.rawgit.com/googlemaps/js-marker-clusterer/gh-pages/images/m' };
            return new MarkerClusterer($scope.map, markers, mcOptions);
        };


        $scope.createMarkerForCity = function (city) {
            var marker = new google.maps.Marker({
                position: new google.maps.LatLng(city.pos[0], city.pos[1]),
                title: city.name
            });
            google.maps.event.addListener(marker, 'click', function () {
                $scope.selectedCity = city;
                $scope.map.showInfoWindow('myInfoWindow', this);
            });
            return marker;
        }

    });

            <!--marker ng-repeat="c in cities" position="{{c.pos}}" title="{{c.name}}" id="{{c.id}}" on-click="showCity(event, c)">
            </marker-->
        </ng-map>
    </div>
