传单:如何在 geojson 图层上使用自定义标记? [英] Leaflet: how to use a custom marker on a geojson layer?

问题描述

我正在尝试在 Leaflet 地图上放置一个 geojson，并且在我使用默认的蓝光标记之前一切正常.

I'm trying to put on a Leaflet map a geojson and all works fine until I use the default blu marker.

现在我想使用一个自定义标记(一个小 .png 图标)，并在下面更改了我的代码

Now I'd like to use a custom marker (a little .png icon) and I've changed my code in the follow

 var my_json;
 $.getJSON('../Dati/my-geojson.geojson', function(data) {
           my_json = L.geoJson(data, {
            pointToLayer: function(feature, latlng) {
                var smallIcon = L.Icon({
                    options: {
                        iconSize: [27, 27],
                        iconAnchor: [13, 27],
                        popupAnchor:  [1, -24],
                        iconUrl: 'icone/chapel-2.png'
                    }
                });
                return L.marker(latlng, {icon: smallIcon});
            },
           onEachFeature: function (feature, layer) {
                   layer.bindPopup(feature.properties.ATT1 + '<br />'
                                                 + feature.properties.ATT2);
           }
         });
 my_json.addTo(markers.addTo(map));
 TOC.addOverlay(my_json, "My layer name in TOC");
 map.removeLayer(my_json); 
 });

我在 Firebug 中看到的错误是

the error that I can see in Firebug is

TypeError: this.options.icon is undefined
var anchor = L.point(this.options.icon.options.popupAnchor || [0, 0]);

出了点问题，但我不知道如何解决.

something is going wrong but I don't know how to fix it.

任何建议将不胜感激

推荐答案

查看 L.icon 文档:你不需要设置 { options: { ... } }.只需直接输入选项，就像文档中所说的那样，并在示例中显示.

See the documentation for L.icon: you don't need to set { options: { ... } }. Just put the options in directly, like it says in the documentation and shows in the example.
