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%;
            width: 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);
