## 实现 ##

1、插件地址

[https://github.com/mapshakers/leaflet-icon-pulse][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);
