Question

我试图通过传单在地图上的标记之间找到路线。我用了那段代码：

L.Routing.control({
waypoints: [
L.latLng(36.9009882, 10.3009531),
L.latLng(36.9922751, 10.1255164)
]}).addTo(map);

但我的地图上没有新东西。有什么遗失的吗？我该怎么办？

Answer 1

1 - 您是否将（Leaflet Routing Machine）包含在您的应用中？ 2- 确保您的地图变量是 (map) 试试这个简单的例子

    var mymap = L.map('mapid').setView([51.505, -0.09], 5);

    L.tileLayer('https://api.mapbox.com/styles/v1/{id}/tiles/{z}/{x}/{y}?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpejY4NXVycTA2emYycXBndHRqcmZ3N3gifQ.rJcFIG214AriISLbB6B5aw', {
        maxZoom: 18,
        attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors, ' +
            'Imagery © <a href="https://www.mapbox.com/">Mapbox</a>',
        id: 'mapbox/streets-v11',
        tileSize: 512,
        zoomOffset: -1
    }).addTo(mymap);

    L.marker([51.5, -0.09]).addTo(mymap)
        .bindPopup("<b>Hello world!</b><br />I am a popup.").openPopup();

    L.marker([53.5, -0.09]).addTo(mymap)
        .bindPopup("<b>Hello world!</b><br />I am a popup.").openPopup();


// route the way leafet machine as I said AI


L.Routing.control({
   waypoints:   [
   L.latLng(51.5, -0.09),
   L.latLng(53.5, -0.09)
   ]
}).addTo(mymap);
