마커 작업

유럽 경제 지역 (EEA) 개발자

createWaypointAdvancedMarkers()를 호출하여 경로 경유지 마커를 만듭니다. 기본적으로 createWaypointAdvancedMarkers()는 각 경유지에 대해 'A', 'B', 'C' 등으로 라벨이 지정된 경로의 마커를 만듭니다. 마커 인덱스 또는 해당 RouteLeg의 속성에 따라 마커 스타일을 변경하는 옵션을 전달하여 마커를 추가로 맞춤설정할 수 있습니다.

다음 코드 샘플은 경로 경유지에 맞춤 마커를 만드는 방법을 보여줍니다.

기본 마커 추가

기본 스타일을 사용하여 마커를 추가하려면 다음 코드 스니펫에 표시된 대로 현재 지도를 지정하는 마커 옵션을 전달하여 createWaypointAdvancedMarkers()를 호출합니다. 

// Create markers using default style.
const markers = await result.routes[0].createWaypointAdvancedMarkers({ map: innerMap });

맞춤 스타일로 마커 추가

맞춤 스타일을 사용하여 마커를 추가하려면 맞춤 스타일 속성이 포함된 마커 옵션을 전달하여 createWaypointAdvancedMarkers()를 호출합니다. 이와 같이 스타일을 적용하면 모든 마커에 동일한 스타일이 적용됩니다. 다음 코드 스니펫은 맞춤 스타일로 마커를 만드는 방법을 보여줍니다. 

// 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);

개별 마커에 맞춤 스타일 적용

개별 마커에 맞춤 스타일을 적용하려면 마커 인덱스 또는 RouteLeg 속성을 기반으로 마커 스타일 옵션을 설정하는 함수를 createWaypointAdvancedMarkers()에 전달하세요. 다음 코드 스니펫은 마커를 만들고 마커 색인에 따라 스타일을 지정하는 함수를 보여줍니다.
