實現

1、下載外掛並引入依賴

<script type="text/javascript" src="
./js/AnimatedMarker.js"></script>

2、新增自定義圖示和軌跡資料組,這裡是兩條軌跡路線

        //新增自定義圖示
        var bikeIcon = L.icon({
            //圖示地址
            iconUrl: './images/marker-bike-green-shadowed.png',
            //圖示大小
            iconSize: [25, 39]
        });

        //軌跡線陣列
        var routeLines = [
               L.polyline([[
36.09, 120.35], [36.10, 120.36], [36.11, 120.37]]), L.polyline([[36.05, 120.33], [36.04, 120.32], [36.03, 120.31]]), ];

3、設定定時器,模擬軌跡移動

        /**開始軌跡移動
        */
        setInterval(function () {
            //標註集合
            var markers = [];
            //新增軌跡移動標註
            $.each(routeLines, function (i, routeLine) {
                
var marker = L.animatedMarker(routeLine.getLatLngs(), { //設定標註圖示 icon: bikeIcon, //開啟移動狀態 autoStart: false, onEnd: function() { // TODO: blow up this marker //移動結束後移除 map.removeLayer(this); } }); //在新位置新增標註 map.addLayer(marker); markers.push(marker); }); for (var i = 0; i < markers.length; i++) { //呼叫start方法,開始移動 markers[i].start(); } }, 5000);
