Question

以下代码显示了一个标记和一个弹出窗口，每当我单击地图时，该弹出窗口就会显示经度和纬度。

我希望标记将颜色从蓝色更改为红色，并且我希望弹出窗口位于标记上方，以使其不覆盖标记。我怎样才能做到这一点？谢谢。

标记使用图标图像进行显示，因此您需要创建自己的自定义图标，其中iconUrl指向要用于标记的图像，然后告诉标记在渲染时使用您的自定义图标。您还可以在图标设置中指定popupAnchor，以将弹出窗口移离图标

示例（Leaflet docs）

var myIcon = L.icon({
  iconUrl: 'my-icon.png',
  iconSize: [38, 95],
  iconAnchor: [22, 94],
  popupAnchor: [-3, -76],
  shadowUrl: 'my-icon-shadow.png',
  shadowSize: [68, 95],
  shadowAnchor: [22, 94]
});

L.marker([50.505, 30.57], {icon: myIcon}).addTo(map);

Mapbox更改标记的位置和颜色
