如何在angularjs中将聚类标记添加到谷歌地图

Question

I am trying to add cluster marker to google maps in angularjs.

I have already included the js file ( https://github.com/googlemaps/js-marker-clusterer/blob/gh-pages/src/markerclusterer.js ) and the images ( https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images ).

However the cluster still not appears.

This is my code:

1. html:

    <section id="GoogleMaps" ng-controller="MapsController"> <div class="container"> <div> <div id="map_canvas"></div> </div> </div> </section> 

2. controller:

    .controller('MapsController', ['$scope', '$http', function ($scope, $http) { $scope.loadData = function () { var url = 'data/LatLng.json'; return $http.get(url).then(function (response) { return response.data; }); }; $scope.initMap = function (data) { var mapOptions = { zoom: 7, center: new google.maps.LatLng(48.209500, 16.370691), mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions); data.forEach(function (item) { var marker = new google.maps.Marker({ position: new google.maps.LatLng(item.LAT, item.LON), animation: google.maps.Animation.Bounce, map: map }); var options = { imagePath: 'images/m' }; var markerCluster = new MarkerClusterer(map, marker, options); }); }; $scope.loadData() .then($scope.initMap); }]) 

3. scripts:

    addTag('script', { src: 'http://maps.googleapis.com/maps/api/js' }, sync); addTag('script', { src: 'assets/js/markerclusterer.js' }, sync); 

Any ideas how to add it?

Thank You.

Initialise the MarkerClusterer as following way.

$scope.initMap = function (data) {
 var mapOptions = {
     zoom: 7,
     center: new google.maps.LatLng(48.209500, 16.370691),
     mapTypeId: google.maps.MapTypeId.ROADMAP
 };
 var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
 var markerArray = [];


 data.forEach(function (item) {
     var marker = new google.maps.Marker({
         position: new google.maps.LatLng(item.LAT, item.LON),
         animation: google.maps.Animation.Bounce,
         map: map
     });

     markerArray.push(marker);
 });

var options = {
    imagePath: 'images/m'
};

var markerCluster = new MarkerClusterer(map, markerArray, options);
};

When you initialize it in forEach loop, it creates new object of it.
