实现
1、插件地址
https://github.com/mapshakers/leaflet-icon-pulse
2、下载插件代码，引入需要的js文件L.Icon.Pulse.js
3、这里直接把css文件放在html中，不再单独引入
.leaflet-pulsing-icon { border-radius: 100%; box-shadow: 1px 1px 8px 0 rgba(0, 0, 0, 0.75); } .leaflet-pulsing-icon:after { content: ""; border-radius: 100%; height: 300%; 300%; position: absolute; margin: -100% 0 0 -100%; } @keyframes pulsate { 0% { transform: scale(0.1, 0.1); opacity: 0; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)"; filter: alpha(opacity=0); } 50% { opacity: 1; -ms-filter: none; filter: none; } 100% { transform: scale(1.2, 1.2); opacity: 0; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)"; filter: alpha(opacity=0); } }
4、声明波动图标并添加到地图
//波动图标声明并设置样式 var pulsingIcon = L.icon.pulse({ iconSize: [20, 20], color: 'red' }); //图标添加到地图上 var marker = L.marker([36.09, 120.35], { icon: pulsingIcon }).addTo(map);
