我的asp.net网站上的GridView中有GoogleMaps（api v3）标记坐标。我想在地图中显示这些标记。问题是标记是彼此的顶部。所有标记都在第一个标记坐标上。我在GridView中有更多的标记（标记是可拖动的）。

更新行 “GMLatLng.push（new google.maps.LatLng（GMLat，GMLng））;”至 “GMLatLng.push（new google.maps.LatLng（lat，lng））;”

你试过吗？
for (i = 0; i < markers.length; i++) {
var data = markers[i]
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
lat_lng.push(myLatlng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title
});
latlngbounds.extend(marker.position);
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.description);
infoWindow.open(map, marker);
});
})(marker, data);
}
map.setCenter(latlngbounds.getCenter());
map.fitBounds(latlngbounds);
