Question

我是AngularJS的新手，目前正在使用谷歌地图 http://angular-ui.github.io/angular-google-maps/

我已经阅读了文档，但我想做的就是显示群集中的数字标记。

以及群集的OnClick，应显示弹出工具文本。 api并未广泛涵盖这一点。我想要实现的例子就在这里

http://104.131.42.57/frontend/index.html

以下是我目前的代码：

HTML指令

<div ng-controller="MapsController">
<ui-gmap-google-map center="map.center" zoom="map.zoom" draggable="true" options="options" bounds="map.bounds">
<ui-gmap-markers doCluster="true" clusterOptions="clusterOptions" models="puMarkers" coords="'self'" icon="'icon'">
</ui-gmap-markers>
</ui-gmap-google-map>

Map Controller，遵循api文档。

controllers.controller('MapsController', function($scope,mapService) {
var locationArray ;
$scope.map = {
    center: {
        latitude: 8.69128,
        longitude: 8.5208073
    },
    zoom: 6,
    bounds: {}
};
$scope.options = {
    scrollwheel: false
};

$scope.clusterOptions = {
    gridSize: 60,
    ignoreHidden: true,
    minimumClusterSize: 5,
    imageExtension: 'png',
    imagePath: 'assets/img/cluster',
    imageSizes: [72] };

var createRandomMarker = function(i, bounds, idKey,point) {
    var ret = {
        latitude: point.g,
        longitude: point.f,
        title: 'm' + i,
        icon: 'assets/img/marker.png',
        options: { title: point.t }
    };
    ret[idKey] = i;
    return ret;
};

$scope.puMarkers = [];
// Get the bounds from the map once it's loaded
$scope.$watch(function() {
    return $scope.map.bounds;
}, function(nv, ov) {
    // Only need to regenerate once
    if (!ov.southwest && nv.southwest) {
        var markers = [];

        /* Load Markers from Rest Services*/
        var promise = mapService.getPollingUnits(1);
        promise.success(function(retData,status,headers,config) {
            if (retData.error == false) {
                var i = 1 ;
                locationArray = retData.events;
                locationArray.forEach(function(item){
                    markers.push(createRandomMarker( i, $scope.map.bounds, "id", item ));
                    i++;
                });
            }
        });
        $scope.puMarkers = markers;
    }
}, true);
});

我终于明白了。群集中的标记数量已经存在，只有它是黑色字体的颜色，因为标记图标也很暗，所以它隐藏了它。单击标记时也显示弹出窗口已经可用在文档中。
