我正在使用 Leaflet 1.2.0 和 Leaflet Routing Machine 3.2.12。

我的代码在地图上绘制了正确的路线，但是，当我想从摘要中访问摘要和 totalDistance 时，两者都未定义。这是为什么？

function createRoute(id, coords) {
            route = L.Routing.control({
                    name: id,
                    serviceUrl: 'http://router.project-osrm.org/route/v1',
                    //router: L.Routing.graphHopper('apiKey');
                    waypoints: coords, //way_points,
                    addWaypoints: false,
                    draggableWaypoints: false,
                    show: false,
                }).on('routesfound', function(e) {
                    console.log(this.summary.totalDistance);
                    // console.log(route.summary.totalDistance);
                     
                })
                    //.on('routesfound', function(e) {
                    //    routes = e.routes;  //is declared and instantiated before the function 
                    //                        // createRoute
                    //    RouteLength = routes[0].summary.totalDistance;
                    //});
                .addTo(map);
    }

错误：路由错误：状态-3 TypeError：无法读取未定义的属性（读取“totalDistance”）。

从控制台我得到升级：

fire    @   leaflet.js:5
(anonym)    @   leaflet-routing-machine.js:16166
(anonym)    @   leaflet-routing-machine.js:18004

onAdd   @   leaflet-routing-machine.js:15919
addTo   @   leaflet.js:5
createRoute @   POI-Dash implement Routing.html:586

有人知道更多吗？

this没有summary. 您将需要参考e.routes，如e.routes[0].summary.totalDistance。
