Создайте маркеры для путевых точек маршрута, вызвав метод createWaypointAdvancedMarkers() . По умолчанию createWaypointAdvancedMarkers() создаёт маркеры маршрута с метками «A», «B», «C» и т. д. для каждой путевой точки. Вы можете дополнительно настроить маркеры, передав параметры для изменения стиля маркера на основе индекса маркера или свойств соответствующего RouteLeg .

Добавить маркеры по умолчанию
Чтобы добавить маркеры, используя стиль по умолчанию, вызовите createWaypointAdvancedMarkers() передав параметр маркера для указания текущей карты, как показано в следующем фрагменте кода.
// Create markers using default style. const markers = await result.routes[0].createWaypointAdvancedMarkers({ map: innerMap });
Добавьте маркеры с пользовательским стилем
Чтобы добавить маркеры с использованием пользовательского стиля, вызовите метод createWaypointAdvancedMarkers() передав параметры маркера, включающие свойства пользовательского стиля. При применении таких стилей все маркеры будут оформлены одинаково. В следующем фрагменте кода показано, как создать маркеры с использованием пользовательского стиля.
// Create markers with a custom style. const markerOptions = { map: innerMap, content: new PinElement({ scale: 1.5, background: '#8C0DD1', borderColor: '#6D0AA5', glyphColor: '#6D0AA5', }).element } const markers = await result.routes[0].createWaypointAdvancedMarkers(markerOptions);
Применить индивидуальный стиль к отдельным маркерам
Чтобы применить собственный стиль к отдельным маркерам, передайте функцию createWaypointAdvancedMarkers() чтобы задать параметры стиля маркера на основе индекса маркера или свойств RouteLeg . В следующем фрагменте кода показана функция для создания маркеров и их стилизации на основе индекса маркера:
