יצירת סמנים באמצעות HTML ו-CSS

בעזרת סמנים מתקדמים תוכלו להשתמש ב-HTML וב-CSS מותאמים אישית כדי: ליצור סמנים בעלי השפעה ויזואלית גבוהה, שיכולים לכלול אינטראקטיביות אנימציה. כל המכונות של AdvancedMarkerElement מתווספות ל-DOM כ-HTML לרכיבים, שניתן לגשת אליהם דרך המאפיין element, ולשנות בדיוק כמו כל רכיב DOM אחר. כי AdvancedMarkerElement הוא DOM אפשר להחיל סגנונות CSS ישירות על סמן ברירת המחדל, וליצור סמנים מותאמים אישית מאפס באמצעות HTML ו-CSS.

הצגת המקור

בדוגמה הבאה אפשר לראות יצירה של רכיב DIV חדש, הקצאת מחלקה של CSS ותוכן טקסט ל-DIV, ולאחר מכן מעבירים את ה-DIV כערך של AdvancedMarkerElement.content:

סמנים מונפשים

הדוגמה הזו יוצרת את הפעולה המסורתית – 'עזיבה מהדף הראשון' אנימציה באמצעות CSS וסמנים מתקדמים. בIntersectionObserver, היא מוסיפה את סגנון CSS drop. ה-IntersectionObserver רואה מתי כל סמן נכנס אזור התצוגה, ומוסיף את הסגנון. לאחר מכן, ה-event listener של animationend שנוספה הפונקציה createMarker() לכל סמן מסירה את הסגנון.
