Leaflet实现动态线路

一、引用Leaflet脚本样式,和Leaflet Ant Path 插件 下载地址: Leaflet:https://leafletjs.com/download.html Leaflet Ant Path:https://github.com/rubenspgcavalcante/leaflet- ......

一、引用leaflet脚本样式,和leaflet ant path 插件

下载地址:

leaflet:

leaflet ant path

使用leaflet ant path 插件要求leaflet的版本大于等于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、地图初始化

 /**
       * 地图初始化
       */
        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、画动态线段

//清楚上一次画的线段
if (gpath) {
                gmap.removelayer(gpath);
            }
var longlatlist =[[****,****],[*****,****]];//经纬度数组
                        var antpath = l.polyline.antpath;
                        gpath = antpath(longlatlist, {
                            "paused": false,     //暂停  初始化状态
                            "reverse": false,  //方向反转
                            "delay": 3000,    //延迟,数值越大效果越缓慢
                            "dasharray": [10, 20], //间隔样式
                            "weight": 3,    //线宽
                            "opacity": 0.5,  //透明度
                            //"color": "#0000ff", //颜色
                            //"pulsecolor": "#ffffff"  //块颜色
                        });
                        gpath.addto(gmap); 

                        // 缩放地图到折线所在区域
                        gmap.fitbounds(gpath.getbounds());
