فیلتری را برمیگرداند که اگر مهر زمانی شی در محدوده معین فیلد تقویم قرار گیرد، عبور میکند.
month
،
day_of_year
،
day_of_month
، و
day_of_week
بر اساس 1 است. زمان ها به UTC فرض می شود. فرض بر این است که هفتهها از دوشنبه به عنوان روز 1 آغاز میشوند. اگر
end
<
start
باشد، این
value
>=
start
یا
value
<=
end
آزمایش میکند تا امکان بستهبندی فراهم شود.
استفاده | برمی گرداند | ee.Filter.calendarRange(start, end , field ) | فیلتر کنید |
استدلال | تایپ کنید | جزئیات | start | عدد صحیح | شروع فیلد تقویم مورد نظر، شامل. |
end | عدد صحیح، پیش فرض: null | انتهای فیلد تقویم مورد نظر، شامل. مقدار پیشفرض همان مقدار شروع است. |
field | رشته، پیشفرض: "day_of_year" | فیلد تقویم برای فیلتر کردن. گزینهها عبارتند از: «سال»، «ماه»، «ساعت»، «دقیقه»، «روز_سال»، «روز_ماه»، و «روز_هفته». |
