Leaflet實現動態線路

一、引用Leaflet腳本樣式，和Leaflet Ant Path 插件

下載地址：

Leaflet：https://leafletjs.com/download.html

Leaflet Ant Path：https://github.com/rubenspgcavalcante/leaflet-ant-path

使用Leaflet Ant Path 插件要求Leaflet的版本大於等於1.0

<link href="~/Scripts/leafletjs/1.4.0/leaflet.css" rel="stylesheet" />
<script src="~/Scripts/leafletjs/1.4.0/leaflet.js"></script>
<script src="~/Scripts/leafletjs/1.4.0/leaflet-ant-path.js"></script>

二、地圖初始化

 /**
       * 地圖初始化
       */
        function mapInit() {
            var amapNormalUrl = '/api/Map/GetMap?type=783085212&zoom={z}&x={x}&y={y}';
            var amapNormalLayer = new L.TileLayer(amapNormalUrl, {
                minZoom: 1,
                maxZoom: 18,
                attribution: ''
            });

            var mapCenter = new L.LatLng(****，****);
            gMap = new L.Map('MapContainer', {
                center: mapCenter,
                zoom: 16,
                minZoom: 1,
                maxZoom: 18,
                layers: [amapNormalLayer]
            });
        }

三、畫動態線段

//清楚上一次畫的線段
if (gPath) {
                gMap.removeLayer(gPath);
            }
var longLatList =[[****,****],[*****,****]];//經緯度數組
                        var antPath = L.polyline.antPath;
                        gPath = antPath(longLatList, {
                            "paused": false,   　　//暫停  初始化狀態
                            "reverse": false,　　//方向反轉
                            "delay": 3000,　　　　//延遲，數值越大效果越緩慢
                            "dashArray": [10, 20],　//間隔樣式
                            "weight": 3,　　　　//線寬
                            "opacity": 0.5,　　//透明度
                            //"color": "#0000FF",　//顏色
                            //"pulseColor": "#FFFFFF"　　//塊顏色
                        });
                        gPath.addTo(gMap); 

                        // 縮放地圖到折線所在區域
                        gMap.fitBounds(gPath.getBounds());
