با فراخوانی تابع createWaypointAdvancedMarkers() میتوانید برای نقاط مسیر، نشانگر ایجاد کنید. به طور پیشفرض، createWaypointAdvancedMarkers() برای هر نقطه مسیر، نشانگرهایی با برچسبهای 'A'، 'B'، 'C' و غیره ایجاد میکند. میتوانید با ارسال گزینههایی برای تغییر سبک نشانگر بر اساس شاخص نشانگر یا ویژگیهای RouteLeg مربوطه، نشانگرها را بیشتر سفارشی کنید.

نمونه کد زیر نحوه ایجاد نشانگرهای سفارشی برای نقاط مسیر را نشان میدهد.

افزودن نشانگرهای پیشفرض
برای افزودن نشانگرها با استفاده از سبک پیشفرض، تابع createWaypointAdvancedMarkers() را فراخوانی کنید و یک گزینه نشانگر برای مشخص کردن نقشه فعلی ارسال کنید، همانطور که در قطعه کد زیر نشان داده شده است.
// Create markers using default style. const markers = await result.routes[0].createWaypointAdvancedMarkers({ map: innerMap });
نشانگرهایی با سبک سفارشی اضافه کنید
برای افزودن نشانگرها با استفاده از یک سبک سفارشی، تابع createWaypointAdvancedMarkers() را فراخوانی کنید و گزینههای نشانگری را که شامل ویژگیهای سبک سفارشی هستند، ارسال کنید. وقتی سبکهایی مانند این را اعمال میکنید، همه نشانگرها به یک شکل سبکبندی میشوند. قطعه کد زیر نحوه ایجاد نشانگرها با یک سبک سفارشی را نشان میدهد.
// 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);
اعمال یک سبک سفارشی به نشانگرهای تکی
برای اعمال یک سبک سفارشی به نشانگرهای منفرد، یک تابع به createWaypointAdvancedMarkers() ارسال کنید تا گزینههای سبک نشانگر را بر اساس شاخص نشانگر یا ویژگیهای RouteLeg تنظیم کنید. قطعه کد زیر تابعی را برای ایجاد نشانگرها و سبکدهی آنها بر اساس شاخص نشانگر نشان میدهد:
