自訂標記

本文說明如何自訂地圖中的車輛和地點標記,以用於消費者適用的網路貨運追蹤應用程式。
使用 JavaScript Consumer SDK,您可以自訂新增至地圖的兩種標記外觀與風格:
方法有以下兩種:
- 最簡單:指定要套用至所有相同類型標記的
MarkerOptions
物件。接著,Consumer SDK 會在兩種情況下套用樣式:將標記新增至地圖前,以及用於標記的資料變更時。
- 進階:指定自訂函式。自訂函式可根據資料設定標記樣式,並為標記新增互動功能,例如點擊處理。具體來說,Consumer SDK 會將標記代表的物件類型 (車輛或目的地) 相關資料傳遞至自訂函式。這樣一來,標記樣式就能根據標記元素本身的目前狀態而變更;舉例來說,就是抵達目的地前剩餘的預定停靠站數量。您甚至可以根據這類資訊,與 Fleet Engine 以外來源的資料聯結,並設定標記樣式。
簡單範例:使用 MarkerOptions
以下範例說明如何使用 MarkerOptions
物件設定車輛標記的樣式。這個範例會將標記不透明度設為 50%。
JavaScript
deliveryVehicleMarkerCustomization = {
opacity: 0.5
};
TypeScript
deliveryVehicleMarkerCustomization = {
opacity: 0.5
};
進階範例:使用自訂函式
以下範例說明如何設定車輛標記的樣式,顯示車輛抵達排定工作停靠站前剩餘的停靠站數。
JavaScript
deliveryVehicleMarkerCustomization =
(params) => {
var stopsLeft = params.taskTrackingInfo.remainingStopCount;
params.marker.setLabel(`${stopsLeft}`);
};
TypeScript
deliveryVehicleMarkerCustomization =
(params: ShipmentMarkerCustomizationFunctionParams) => {
const stopsLeft = params.taskTrackingInfo.remainingStopCount;
params.marker.setLabel(`${stopsLeft}`);
};
在標記中新增點擊處理常式
您可以為任何標記新增點擊處理作業,例如車輛標記的下列範例。
JavaScript
deliveryVehicleMarkerCustomization =
(params) => {
if (params.isNew) {
params.marker.addListener('click', () => {
// Perform desired action.
});
}
};
TypeScript
deliveryVehicleMarkerCustomization =
(params: ShipmentMarkerCustomizationFunctionParams) => {
if (params.isNew) {
params.marker.addListener('click', () => {
// Perform desired action.
});
}
};
顯示標記的其他資訊
您可以使用 InfoWindow
顯示車輛或其他地點標記的額外資訊。以下範例會建立 InfoWindow
,並附加至車輛標記:
JavaScript
// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
{disableAutoPan: true});
locationProvider.addListener('update', e => {
const stopsCount =
e.taskTrackingInfo.remainingStopCount;
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.FleetEngineShipmentLocationProviderUpdateEvent) => {
const stopsCount =
e.taskTrackingInfo.remainingStopCount;
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();

The Consumer SDK then applies the styling in two situations: before adding the markers to the map, and when the data used for the markers have changed.\n- **More advanced**: Specify a customization function. Customization functions allow for styling of the markers based on data, as well as adding interactivity to markers, such as click handling. Specifically, the Consumer SDK passes data to the customization function about the type of object the marker represents: vehicle or destination. This then allows marker styling to change based on the current state of the marker element itself; for example, the number of planned stops remaining until the destination. You can even join against data from sources outside Fleet Engine and style the marker based on that information.\n\nSimple example: use `MarkerOptions`\n\nThe following example shows how to configure a vehicle marker's styling with a\n`MarkerOptions` object. This example sets the marker opacity to 50%.\n\n\u003cbr /\u003e\n\nJavaScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization = {\n opacity: 0.5\n };\n\n\u003cbr /\u003e\n\nTypeScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization = {\n opacity: 0.5\n };\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nAdvanced example: use a customization function\n\nThe following example shows how to configure a vehicle marker's styling to\ndisplay the remaining stop count for the vehicle before reaching the stop for\nthe scheduled task.\n\n\u003cbr /\u003e\n\nJavaScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params) =\u003e {\n var stopsLeft = params.taskTrackingInfo.remainingStopCount;\n params.marker.setLabel(`${stopsLeft}`);\n };\n\n\u003cbr /\u003e\n\nTypeScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params: ShipmentMarkerCustomizationFunctionParams) =\u003e {\n const stopsLeft = params.taskTrackingInfo.remainingStopCount;\n params.marker.setLabel(`${stopsLeft}`);\n };\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nAdd click handling to markers\n\nYou can add click handling to any marker, such as in the following example\nfor a vehicle marker.\n\n\u003cbr /\u003e\n\nJavaScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params) =\u003e {\n if (params.isNew) {\n params.marker.addListener('click', () =\u003e {\n // Perform desired action.\n });\n }\n };\n\n\u003cbr /\u003e\n\nTypeScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params: ShipmentMarkerCustomizationFunctionParams) =\u003e {\n if (params.isNew) {\n params.marker.addListener('click', () =\u003e {\n // Perform desired action.\n });\n }\n };\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nDisplay additional information for markers\n\nYou can use an [`InfoWindow`](/maps/documentation/javascript/infowindows) to display additional information about a\nvehicle or location marker.
