实现
1、添加标记
//添加一个标记 L.marker([36.09, 120.35]).addTo(map).bindPopup("公众号:霸道的程序猿<br>").openPopup();
效果
2、添加折线
//添加一条折线 var polyline = L.polyline([ [36.1, 120.32], [36.05, 120.3] ],{color: '#FFFF00'}).addTo(map).bindPopup("这是折线");
效果
3、添加圆圈
//添加一个圆圈 L.circle([36.01, 120.22], 5000, { color: 'red', fillColor: '#f03', fillOpacity: 0.5 }).addTo(map).bindPopup("青岛欢迎你");
效果
4、添加多边形
//添加一个多边形 L.polygon([ [39.92096, 116.38591], [39.91079, 116.38676], [39.91118, 116.3962], [39.92014, 116.39482] ]).addTo(map).bindPopup("故宫");
效果
5、点击地图弹窗显示坐标
//弹窗显示点击处的坐标 var popup = L.popup(); function onMapClick(e) { popup .setLatLng(e.latlng) .setContent("You clicked the map at " + e.latlng.toString()) .openOn(map); } map.on('click', onMapClick);
效果
