場景

Leaflet中添加標記、折線、圓圈、多邊形、彈窗顯示點擊處坐標:

在上面加載標記使用的是默認圖標,如果要自定義圖標怎么用。

官網有詳細的教程

實現

1、與官方教程一樣,准備一張陰影照片,三張不同顏色的icon

 

 

 

 

 

 

 

 

2、創建ICON構造函數,相當於繼承ICON,可以重新設置屬性

        //創建ICON構造函數,相當於繼承於ICON,可以重新設置屬性
        var LeafIcon = L.Icon.extend({
            options: {
                shadowUrl: './icon/leaf-shadow.png', //陰影地址
                iconSize: [38, 95],  //圖標寬高
                shadowSize: [50, 64], //陰影寬高
                iconAnchor: [22, 94], //圖標錨點
                shadowAnchor: [4, 62], //陰影錨點
                popupAnchor: [-3, -76] //彈出框彈出位置,相對於圖標錨點
            }
        });

3、創建多個icon

        //創建多個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、創建marker添加到地圖上

        //創建marker添加到地圖上
        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);

5、完整代碼

                popupAnchor: [-3, -76] //彈出框彈出位置,相對於圖標錨點
            }
        });

        //創建多個icon
        var greenIcon = new LeafIcon({
                iconUrl: './icon/leaf-green.png'
            }),

            orangeIcon = new LeafIcon({

            });

        //創建marker添加到地圖上

            icon: greenIcon
        }).bindPopup("I am a green leaf.").addTo(map);
        L.marker([36.13, 120.25], {

        L.marker([36.16, 120.15], {
