Google Maps Multiple markers with the exact same location Not working
非常感谢

这个解决方案很棒，但我会看一下使用Overlapping Marker Spiderfier库来处理同一位置的标记。您可以将其与标记群集库结合使用，而不会出现任何问题。通过这种方式，您也不会失去查看实际位于同一位置的标记数量的能力 - 在我看来，它为您提供了一个很棒的用户界面。
要使用重叠标记Spiderfier，请在html中的主js文件之前包含脚本文件。然后在你的js中，创建一个OverlappingMarkerSpiderfier对象的实例：
var oms = new OverlappingMarkerSpiderfier(map);
/*in your case I'd do this after you initialize the `map` object,
*and declare the `oms` globally, like you do with your other global objects
*/
然后，在创建标记时，您希望通过oms方法将标记添加到addMarker()对象。因此，在您为renderElements()声明的click事件侦听器后，在marker函数中添加以下行：
oms.addMarker(marker);
最后，通过在该函数中添加以下函数，确保在调用代码中的oms函数时清除removeMarkers()对象中的标记：
oms.clearMarkers();
