Question

我有一个应用程序，我正在使用Google Map API显示用户使用lat / lon发布的帖子的标记。我使用了MarkerClusterer功能来更好地组织标记，这种标记有效，但有各种各样的错误。

基本上，我一直在家测试这个，所以所有测试帖的lat / lon都是一样的。在使用MarkerClusterer之前，远远地缩放到地图中最终会显示所有标记。不幸的是，使用MarkerClusterer，例如，如果列出了非常接近的标记数量的“5”，例如这些测试帖，则单击群集不会显示任何内容。当它们非常接近时，没有标记出现。重申一下，这些标记确实没有MarkerClusterer。

我在另一篇帖子中升级到MarkerClustererPlus v2.0.9，该帖子描述了MarkerClusterer的其他问题，但尚未解决问题。

非常感谢对这个问题的任何见解。

编辑：geocodezip建议使用overlapmarkerspidifier，这听起来不错，但我的代码相当复杂，我不知道如何合并它。任何见解都非常感激。代码如下：

function mainGeo()
{
     if (navigator.geolocation) 
        {
          navigator.geolocation.getCurrentPosition( mainMap, error, {maximumAge: 30000, timeout: 10000, enableHighAccuracy: true} );
    }
    else
    {
          alert("Sorry, but it looks like your browser does not support geolocation.");
    }
}


var stories = {{storyJson|safe}};
var geocoder;
var map;
var markers = [];

function loadMarkers(stories){

    for (i=0;i<stories.length;i++) {
        var story = stories[i];    
        if (story.copy.length > 120) {
                story.copy = story.copy.substring(0, 120) + "...";
            }

        (function(story) {      
            var pinColor = "69f2ff";
                var pinImage = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=S|" + pinColor,
                    new google.maps.Size(21, 34),
                    new google.maps.Point(0,0),
                    new google.maps.Point(10, 34));
          var point = new google.maps.LatLng(story.latitude, story.longitude);
          var marker = new google.maps.Marker({position: point, map: map, icon: pinImage});
          var infowindow = new google.maps.InfoWindow({
            content: '<div >'+
                '<div >'+
                '</div>'+
                '<h2 class="firstHeading">'+story.headline+'</h2>'+
                '<div>'+
                '<span>'+story.author+'</span><br />'+
                '<span>'+story.city+'</span><br />'+
                '<span>'+story.topic+'</span><br />'+
                '<p>'+story.date+'</p>'+
                '<p>'+story.copy+'</p>'+
                '<p><a href='+story.url+'>Click to read story</a></p>'+
                '</div>'+
                '</div>'

          });

          google.maps.event.addListener(marker, 'click', function() {
            infowindow.open(map,this);

          });
            markers.push(marker);

        })(story);

    }

}

也许这post in the v3 group: Overlapping markers on your Google Map? Meet OverlappingMarkerSpiderfier可能会有所帮助：

听起来像OverlapingMarkerSpiderifier解决了你的问题。
