我正在为所有标记创建自定义信息窗口，因为我想在标记中显示用户图标。我想在地图上的标记处打开所有标记，但我无法做到这一点。
这是我的代码。

答案 0 :(得分：0)
尝试实施此代码
GEvent.addListener(marker, 'click', function() {
var markerPosn = new GLatLng(place["posn"][0], place["posn"][1]);
map.openInfoWindowHtml(markerPosn ,buildPlaceInfoHtml(place),{maxWidth:275});
});
我希望这对你有所帮助。
