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);
