ایجاد نشانگر با HTML و CSS

با نشانگرهای پیشرفته می توانید از HTML و CSS سفارشی برای ایجاد نشانگرهایی با تأثیر بصری بالا استفاده کنید که می توانند تعامل و انیمیشن را داشته باشند. تمام نمونه های AdvancedMarkerElement به عنوان عناصر HTML به DOM اضافه می شوند که می توانید از طریق ویژگی element به آنها دسترسی داشته باشید و به همان روشی که هر عنصر DOM دیگری دستکاری کنید. از آنجایی که AdvancedMarkerElement یک عنصر DOM است، می‌توانید مستقیماً استایل‌های CSS را روی نشانگر پیش‌فرض اعمال کنید و نشانگرهای سفارشی را کاملاً از ابتدا با استفاده از HTML و CSS ایجاد کنید.

مثال زیر ایجاد یک عنصر DIV جدید، اختصاص یک کلاس CSS و محتوای متنی به DIV، سپس ارسال DIV به عنوان مقدار AdvancedMarkerElement.content را نشان می دهد:

نشانگرهای متحرک

این مثال انیمیشن سنتی "جهش قطره" را با استفاده از CSS و نشانگرهای پیشرفته ایجاد می کند. در IntersectionObserver ، سبک drop را اضافه می کند. IntersectionObserver می بیند که هر نشانگر چه زمانی وارد viewport می شود و سبک را اضافه می کند. سپس، شنونده رویداد animationend که تابع createMarker() به هر نشانگر اضافه کرده است، سبک را حذف می کند.

با نشانگرهای پیشرفته می توانید از HTML و CSS سفارشی برای ایجاد نشانگرهایی با تأثیر بصری بالا استفاده کنید که می توانند تعامل و انیمیشن را داشته باشند. تمام نمونه های AdvancedMarkerElement به عنوان عناصر HTML به DOM اضافه می شوند که می توانید از طریق ویژگی element به آنها دسترسی داشته باشید و به همان روشی که هر عنصر DOM دیگری دستکاری کنید. از آنجایی که AdvancedMarkerElement یک عنصر DOM است، می‌توانید مستقیماً استایل‌های CSS را روی نشانگر پیش‌فرض اعمال کنید و نشانگرهای سفارشی را کاملاً از ابتدا با استفاده از HTML و CSS ایجاد کنید.

نشانگرهای متحرک

این مثال انیمیشن سنتی "جهش قطره" را با استفاده از CSS و نشانگرهای پیشرفته ایجاد می کند. در IntersectionObserver ، سبک drop را اضافه می کند. IntersectionObserver می بیند که هر نشانگر چه زمانی وارد viewport می شود و سبک را اضافه می کند. سپس، شنونده رویداد animationend که تابع createMarker() به هر نشانگر اضافه کرده است، سبک را حذف می کند.
