Angularjs 同一位置上有多个标记google maps，因此重叠标记

所以我想使用重叠标记。任何人都可以帮助我如何使用它？？ 我已经在html中使用了库

并将重叠的MarkersPiderfer代码放入我遇到的错误中，以便plz任何人都可以帮助我解决此问题。

尝试使用类似的方法

您将找到详细信息文档。与此相关的代码请参考此

，哪里会出现错误？

for (var i = 0; i < window.mapData.length; i ++) {
  var datum = window.mapData[i];
  var loc = new gm.LatLng(datum.lat, datum.lon);
  var marker = new gm.Marker({
    position: loc,
    title: datum.h,
    map: map
  });
  marker.desc = datum.d;
  oms.addMarker(marker);  // <-- here
}
