javascript - 谷歌地图MarkerClusterer不聚类

Question

抱歉，我到处搜索，似乎无法弄清楚这个问题。我有一张工作正常的 map ，但我正在尝试添加 MarkerClusterer 并且标记没有聚类。新泽西州的位置应该位于一个集群中。谁能提供一些提示吗？

这是我的页面: http://vbarbershop.com/location-finder/

我收到这些 JavaScript 错误，这可能是原因吗？我对谷歌地图有点缺乏经验:未捕获的类型错误:未定义不是函数markerclusterer.js:660未捕获的类型错误:未定义不是函数markerclusterer.js:660

这是我的代码:

MarkerClusterer 管理 google.maps.Marker 对象的数组。位置数组的类型不正确。

将标记添加到 map 时创建标记数组，使用该数组作为 MarkerClusterer 构造函数的参数。

var map = new google.maps.Map(document.getElementById('mymap'), {
  zoom: 4,
  center: new google.maps.LatLng(39.183608, -96.571669),
  scrollwheel: false,
  scaleControl: true,
  mapTypeId: google.maps.MapTypeId.ROADMAP
});

var iconBase = 'http://vbarbershop.com/wp-content/themes/vbarbershop/library/images/';

    var gmarkers = [];
for (i = 0; i < locations.length; i++) {

    var marker = new google.maps.Marker({
        position: new google.maps.LatLng(locations[i][2], locations[i][3]),
        draggable: false,
        icon: iconBase + 'ico-marker.png',
        map: map
    });

    var content = '<a href="' + locations[i][1] +  '" class="maplink">' + locations[i][0] + '</a>'

    var infowindow = new google.maps.InfoWindow();

    google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
        return function() {
            /* close the previous info-window */
            closeInfos();
            infowindow.setContent(content);
            infowindow.open(map,marker);
            /* keep the handle, in order to close it on next click event */
            infos[0]=infowindow;
        };
    })(marker,content,infowindow));
    gmarkers.push(marker);
}

function closeInfos(){
   if(infos.length > 0){
      /* detach the info-window from the marker ... undocumented in the API docs */
      infos[0].set('marker', null);
      /* and close it */
      infos[0].close();
      /* blank the array */
      infos.length = 0;
   }
}

var markerCluster = new MarkerClusterer(map, gmarkers);
