Question

我是网络地图和传单开发的初学者...我找到了一个简单但有用的代码，我想知道如何用mylocal.png（或.svg）交换下面HTML代码中的所有传单标记。提前感谢您的任何反馈！这是一个美好的一天

$.get(api, {data: query}, function(resp) {
  var geojson = osmtogeojson(resp);
  var layer = L.geoJson(geojson).addTo(map);
  map.fitBounds(layer.getBounds());
  });
</script>

Answer 1

默认情况下，当使用L.GeoJSON时，GeoJSON数据中的每个点都会变为默认L.Marker。您可以使用pointToLayer的{{1}}选项返回自定义L.GeoJSON，其L.Marker使用您的图片。

L.Icon

L.GeoJSON教程：http://leafletjs.com/examples/geojson.html
自定义图标教程：http://leafletjs.com/examples/custom-icons.html

Answer 2

试试这个：

var greenIcon = L.icon({
    iconUrl: 'leaf-green.png', // url to your custome icon


    iconSize:     [38, 95], // size of the icon
    shadowSize:   [50, 64], // size of the shadow
    iconAnchor:   [22, 94], // point of the icon which will correspond to marker's location
    shadowAnchor: [4, 62],  // the same for the shadow
    popupAnchor:  [-3, -76] // point from which the popup should open relative to the iconAnchor
});

然后把它放到地图initilize

L.marker([51.5, -0.09], {icon: greenIcon}).addTo(map);

是的。
