HTML ve CSS ile işaretçi oluşturma

Gelişmiş işaretçilerle, etkileşim ve animasyon içerebilen, görsel etkisi yüksek işaretçiler oluşturmak için özel HTML ve CSS kullanabilirsiniz. Tüm AdvancedMarkerElement örnekleri, DOM'e HTML öğeleri olarak eklenir. Bu öğelere element mülkü aracılığıyla erişebilir ve diğer DOM öğeleriyle aynı şekilde değiştirebilirsiniz. AdvancedMarkerElement bir DOM öğesi olduğundan varsayılan işaretçiye doğrudan CSS stilleri uygulayabilir ve HTML ile CSS'yi kullanarak tamamen sıfırdan özel işaretçiler oluşturabilirsiniz.

Basit HTML işaretçisi

Bu örnek haritada basit bir özel HTML işaretçisinin nasıl oluşturulacağı gösterilmektedir:

Aşağıdaki örnekte, yeni bir DIV öğesi oluşturulması, DIV'ye bir CSS sınıfı ve metin içeriği atanması ve ardından DIV'nin AdvancedMarkerElement.content değeri olarak iletilmesi gösterilmektedir:

Animasyonlu işaretçiler

Bu örnekte, CSS ve gelişmiş işaretçiler kullanılarak geleneksel "zıplama-düşme" animasyonu oluşturulmaktadır. IntersectionObserver öğesine drop CSS stili eklenir. IntersectionObserver, her işaretçi görüntü alanına girdiğinde stili ekler. Ardından, createMarker() işlevinin her işaretçiye eklediği animationend etkinlik dinleyicisi stili kaldırır.
