路由控件名称和添加自定义标记

Routing control name and add custom markers

您好,我正在尝试使用传单添加自定义标记并使用 Routing.control 绘制路线。我需要向标记添加一个变量,因为我需要不时更新其中一个标记位置。我只会有 3 个标记或 waypoints,一个开始,一个第二个和第三个。我可能只需要移动开始标记。

绘制路线并添加默认标记的添加路线代码为

var route = L.Routing.control({
     waypoints: [
    L.latLng(my_lat, my_lng),
    L.latLng(job_p_lat, job_p_lng),
    L.latLng(job_d_lat, job_d_lng)
 ],show: false, units: 'imperial',
 router: L.Routing.mapbox('API KEY HERE')
}).addTo(map);

我已经尝试了 q 一些不值得展示的东西,因为什么都没做。任何建议都很好,谢谢

如果您查看此 issue,您会发现关于不同标记图标的问题已得到解答。

L.Routing.controlcreateMarker 选项函数可以像这样使用:

// source: https://github.com/pointhi/leaflet-color-markers
var greenIcon = new L.Icon({
  iconUrl: 'https://cdn.rawgit.com/pointhi/leaflet-color-markers/master/img/marker-icon-2x-green.png',
  shadowUrl: 'https://cdnjs.cloudflare.com/ajax/libs/leaflet/1.3.4/images/marker-shadow.png',
  iconSize: [25, 41],
  iconAnchor: [12, 41],
  popupAnchor: [1, -34],
  shadowSize: [41, 41]
});
L.Routing.control({
  waypoints: [
    L.latLng(57.74, 11.94),    // startmarker
    L.latLng(57.6792, 11.949) // endmarker
  ],
  createMarker: function(i, wp, nWps) {
    if (i === 0 || i === nWps - 1) {
      // here change the starting and ending icons
      return L.marker(wp.latLng, {
        icon: greenIcon // here pass the custom marker icon instance
      });
    } else {
      // here change all the others
      return L.marker(wp.latLng, {
        icon: yourOtherCustomIconInstance
      });
    }
  }
}).addTo(map);

Demo - 以隐身方式打开它 window,因为 API 有请求限制。

您应该会看到如下内容:

更新:要动态更改路线,您必须这样做:

将您的路由控制实例存储到一个变量中:var control = L.Routing.control({...})

然后像这样更改标记位置:

// this is the starting marker latitude
control.getRouter().options.waypoints[0].lat = L.latLng(59.74, 11.94);

// similarly for longitude and for ending marker to change the position dynamically

然后刷新路由图:

control.route();
createMarker: function(i, waypoints, n) {
                    var startIcon = L.icon({
                        iconUrl: '/maps/green.png',
                        iconSize: [30, 48]
                    });
                    var sampahIcon = L.icon({
                        iconUrl: '/maps/yellow.png',
                        iconSize: [30, 48]
                    });
                    var destinationIcon = L.icon({
                        iconUrl: '/maps/red.png',
                        iconSize: [30, 48]
                    });
                    if (i == 0) {
                        marker_icon = startIcon
                    } else if (i > 0 && i < n - 1) {
                        marker_icon = sampahIcon
                    } else if (i == n - 1) {
                        marker_icon = destinationIcon
                    }
                    var marker = L.marker(waypoints.latLng, {
                        draggable: false,
                        bounceOnAdd: false,
                        bounceOnAddOptions: {
                            duration: 1000,
                            height: 800,
                            function() {
                                (bindPopup(myPopup).openOn(mymap))
                            }
                        },
                        icon: marker_icon
                    }).bindPopup('<h4>' + mylocs[i].nama_tps + '</h4><br>' +
                        mylocs[i].mylat + '<br>' + mylocs[i].mylong)
                    return marker
                }
