在上面加载标记使用的是默认图标，如果要自定义图标怎么用。

官网有详细的教程

实现

1、与官方教程一样，准备一张阴影照片，三张不同颜色的icon

2、创建ICON构造函数，相当于继承ICON，可以重新设置属性


        //创建ICON构造函数，相当于继承于ICON，可以重新设置属性
        var LeafIcon = L.Icon.extend({
            options: {
                shadowUrl: './icon/leaf-shadow.png', //阴影地址
                iconSize: [38, 95],  //图标宽高
                shadowSize: [50, 64], //阴影宽高
                iconAnchor: [22, 94], //图标锚点
                shadowAnchor: [4, 62], //阴影锚点
                popupAnchor: [-3, -76] //弹出框弹出位置，相对于图标锚点
            }
        });

3、创建多个icon


        //创建多个icon
        var greenIcon = new LeafIcon({
                iconUrl: './icon/leaf-green.png'
            }),
            redIcon = new LeafIcon({
                iconUrl: './icon/leaf-red.png'
            }),
            orangeIcon = new LeafIcon({
                iconUrl: './icon/leaf-orange.png'
            });

4、创建marker添加到地图上


        //创建marker添加到地图上
        L.marker([36.09, 120.35], {
            icon: greenIcon
        }).bindPopup("I am a green leaf.").addTo(map);
        L.marker([36.13, 120.25], {
            icon: redIcon
        }).bindPopup("I am a red leaf.").addTo(map);
        L.marker([36.16, 120.15], {
            icon: orangeIcon
        }).bindPopup("I am an orange leaf.").addTo(map);
