我有这张地图,并根据用户经纬度显示指针。现在我对OverlappingMarkerSpiderfier有问题。当多于1个用户的long和lat相同时。例如:5人居住在同一栋建筑物中。我需要OverlappingMarkerSpiderfier来显示计数,然后单击以sipderfy。默认情况下,OverlappingMarkerSpiderfier不会那样工作。
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(52, 8),
zoom: 4
};
map = new google.maps.Map(document.getElementById('map'), mapOptions);
var oms = new OverlappingMarkerSpiderfier(map,{markersWontMove: true, markersWontHide: true, keepSpiderfied: true});
markerClusterer.setMap(map);
这是jsfiddle http://jsfiddle.net/gL3L7zso/62/
如您所见,当我单击battefield 3时,它的后面隐藏着1个指针。3.我需要它保持不变,但是要显示隐藏在后面的指针数。
感谢任何解决方案。

最佳答案
一种选择是在“群集”中的每个标记上放置一个标签,然后将标记最高的标记放在顶部。
oms.addMarker(marker);
var markersNear = oms.markersNearMarker(marker, false);
marker.setLabel("" + (markersNear.length + 1));
marker.setOptions({
zIndex: markersNear.length
});
