İşaretçilerle çalışma

Avrupa Ekonomik Alanı (AEA) geliştiricileri

createWaypointAdvancedMarkers() işlevini çağırarak rota ara noktaları için işaretçiler oluşturun. Varsayılan olarak createWaypointAdvancedMarkers(), her bir ara nokta için "A", "B", "C" vb. olarak etiketlenmiş rota işaretçileri oluşturur. İşaretçi stilini işaretçi dizinine veya ilgili RouteLeg özelliklerine göre değiştirmek için seçenekler ileterek işaretçileri daha da özelleştirebilirsiniz.

Varsayılan işaretçiler ekleme

Varsayılan stili kullanarak işaretçi eklemek için aşağıdaki kod snippet'inde gösterildiği gibi, geçerli haritayı belirtmek üzere bir işaretçi seçeneği ileterek createWaypointAdvancedMarkers() işlevini çağırın. 

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

Özel stile sahip işaretçiler ekleme

Özel stil kullanarak işaretçi eklemek için createWaypointAdvancedMarkers() özel stil özelliklerini içeren işaretçi seçeneklerini iletin. Bu gibi stilleri uyguladığınızda tüm işaretçiler aynı şekilde stillendirilir. Aşağıdaki kod snippet'inde, özel stile sahip işaretçilerin nasıl oluşturulacağı gösterilmektedir. 

// 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);

İşaretçilere ayrı ayrı özel stil uygulama

Özel bir stili tek tek işaretçilere uygulamak için createWaypointAdvancedMarkers() işlevine bir işlev iletin. Bu işlev, işaretçi stili seçeneklerini işaretçi dizinine veya RouteLeg özelliklerine göre ayarlar. Aşağıdaki kod snippet'inde, işaretçiler oluşturup işaretçi dizinine göre stil uygulayan bir işlev gösterilmektedir:
