leaflet之自定义marker图标
marker图标可以设置自定义的图片，以及阴影图片
- 准备图片
- 创建原始图标ICON
- 依据原始图标创建多个图标ICON
- 添加到地图上
准备图片
创建原始图标ICON
var greenIcon = L.icon({
iconUrl: 'leaf-green.png',//图标地址
shadowUrl: '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
});
依据原始图标创建多个图标ICON
创建icon构造函数
var LeafIcon = L.Icon.extend({
options: {
shadowUrl: 'leaf-shadow.png',
iconSize: [38, 95],
shadowSize: [50, 64],
iconAnchor: [22, 94],
shadowAnchor: [4, 62],
popupAnchor: [-3, -76]
}
});
相当于继承与ICON,可以重新设置属性
//创建多个icon
var greenIcon = new LeafIcon({iconUrl: 'leaf-green.png'}),
redIcon = new LeafIcon({iconUrl: 'leaf-red.png'}),
orangeIcon = new LeafIcon({iconUrl: 'leaf-orange.png'});
创建marker添加到地图上
L.marker([51.5, -0.09], {icon: greenIcon}).addTo(map).bindPopup("I am a green leaf.");
L.marker([51.495, -0.083], {icon: redIcon}).addTo(map).bindPopup("I am a red leaf.");
L.marker([51.49, -0.1], {icon: orangeIcon}).addTo(map).bindPopup("I am an orange leaf.");
