本文档介绍了如何自定义地图的外观和风格，以及如何控制数据可见性和视口选项。为此，您可以执行以下操作：
- 使用云端地图样式设置
- 直接在您自己的代码中设置地图样式选项
使用云端地图样式设置为地图设置样式
若要将地图样式应用于 JavaScript 用户行程共享地图，请在创建 JourneySharingMapView 时指定 mapId 和任何其他 mapOptions。
以下示例展示了如何使用地图 ID 应用地图样式。
JavaScript
const mapView = new google.maps.journeySharing.JourneySharingMapView({
element: document.getElementById('map_canvas'),
locationProviders: [locationProvider],
mapOptions: {
mapId: 'YOUR_MAP_ID'
}
// Any other styling options.
});
TypeScript
const mapView = new google.maps.journeySharing.JourneySharingMapView({
element: document.getElementById('map_canvas'),
locationProviders: [locationProvider],
mapOptions: {
mapId: 'YOUR_MAP_ID'
}
// Any other styling options.
});
直接在您自己的代码中设置地图样式
您还可以在创建 JourneySharingMapView 时设置地图选项，以自定义地图样式。以下示例展示了如何使用地图选项设置地图样式。如需详细了解您可以设置哪些地图选项，请参阅 Google Maps JavaScript API 参考中的 mapOptions。
JavaScript
const mapView = new google.maps.journeySharing.JourneySharingMapView({
element: document.getElementById('map_canvas'),
locationProviders: [locationProvider],
mapOptions: {
styles: [
{
"featureType": "road.arterial",
"elementType": "geometry",
"stylers": [
{ "color": "#CCFFFF" }
]
}
]
}
});
TypeScript
const mapView = new google.maps.journeySharing.JourneySharingMapView({
element: document.getElementById('map_canvas'),
locationProviders: [locationProvider],
mapOptions: {
styles: [
{
"featureType": "road.arterial",
"elementType": "geometry",
"stylers": [
{ "color": "#CCFFFF" }
]
}
]
}
});
在地图上显示信息
使用 InfoWindow 显示与车辆或位置标记有关的其他信息。如需了解详情，请参阅 InfoWindow。
以下示例展示了如何创建 InfoWindow 并将其附加到车辆标记：
JavaScript
// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
{disableAutoPan: true});
locationProvider.addListener('update', e => {
const stopsCount = e.trip.remainingWaypoints.length;
infoWindow.setContent(
`Your vehicle is ${stopsCount} stops away.`);
// 2. Attach the info window to a vehicle marker.
// This property can return multiple markers.
const marker = mapView.vehicleMarkers[0];
infoWindow.open(mapView.map, marker);
});
// 3. Close the info window.
infoWindow.close();
TypeScript
// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
{disableAutoPan: true});
locationProvider.addListener('update', (e: google.maps.journeySharing.FleetEngineTripLocationProviderUpdateEvent) => {
const stopsCount = e.trip.remainingWaypoints.length;
infoWindow.setContent(
`Your vehicle is ${stopsCount} stops away.`);
// 2. Attach the info window to a vehicle marker.
// This property can return multiple markers.
const marker = mapView.vehicleMarkers[0];
infoWindow.open(mapView.map, marker);
});
// 3. Close the info window.
infoWindow.close();
停用自动修剪
您可以停用自动调整功能，让地图不再自动将视口调整为适合车辆和预计路线的大小。以下示例展示了如何在配置行程分享地图视图时停用自动调整大小。
JavaScript
const mapView = new
google.maps.journeySharing.JourneySharingMapView({
element: document.getElementById('map_canvas'),
locationProviders: [locationProvider],
automaticViewportMode:
google.maps.journeySharing
.AutomaticViewportMode.NONE,
...
});
TypeScript
const mapView = new
google.maps.journeySharing.JourneySharingMapView({
element: document.getElementById('map_canvas'),
locationProviders: [locationProvider],
automaticViewportMode:
google.maps.journeySharing
.AutomaticViewportMode.NONE,
...
});
