1. 自定义标记的图标，而不是像您现在看到的那样颜色不同。
2.在Control图层上添加不同的Icon。
示例图片:
最佳答案
看看这个 example用于创建自定义传单标记。
这个想法是，您可以使用自定义图标图像创建标记，而不是将标记点转换为 L.circleMarker。
由于听起来您将有多个图标，因此最好创建一个图标类:
var myIcon = L.Icon.extend({
options: {
iconSize: [38, 95],
iconAnchor: [22, 94],
popupAnchor: [-3, -76]
}
});
然后，当您实例化图标时，您可以设置自定义图标图像。
var firstIcon = new myIcon({iconUrl: 'first-icon.png'}),
anotherIcon = new myIcon({iconUrl: 'another-icon.png'}),
yetAnotherIcon = new myIcon({iconUrl: 'tet-another.png'});
pointToLayer: function(feature, latlng) {
if(feature.properties.pname == '66_marker'){
return L.marker(latlng, {icon: firstIcon});
} else if (feature.properties.pname == '73_marker'){
return L.marker(latlng, {icon: anotherIcon});
}
}
要为图层控件创建自定义图标，您可以在 css 中创建图标类。当您将图层添加到图层控件时，您可以添加图标。
overlaysObj[categoryName] = '<span class="custom-icon"></span>' + categoryLG;
祝你好运。
