Question

我必须能够在地图中绘制矩形，圆形和多边形，并显示形状边界内的标记。

它适用于圆形和矩形，但对于多边形，我似乎没有正确计算它。我关注了this教程

问题：

我使用的功能：

lastBounds = lastShape.getBounds();
if (google.maps.geometry.poly.containsLocation(new google.maps.LatLng(hotel.lat, hotel.long), lastShape)) {
    marker = new google.maps.Marker({
        position: new google.maps.LatLng(hotel.lat, hotel.long),
        map: map,
        title: hotel.name,
        icon: icon
    });
    markers.push(marker);
}

知道为什么多边形外面的标记仍在被推动？

Answer 1

如果您在代码段中遇到API密钥问题，请不要包含密钥......

现在关于你的代码，虽然这不是我所说的 minimal 代码，但我可以告诉它它按预期工作。只有您的自定义标记图标不会显示在正确的位置。

使用默认标记检查下面的代码。它工作正常。

查看有关Icon的文档。最有可能的问题必须是您的锚点。
