¥Return value

一个整数，表示根据通用时间给定日期的年份。如果日期是 invalid，则返回 NaN。

¥An integer representing the year for the given date according to universal time. Returns NaN if the date is invalid.

¥Description

与 getYear() 不同，getUTCFullYear() 返回的值是绝对数字。对于 1000 年到 9999 年之间的日期，getFullYear() 返回一个四位数字，例如 1995。使用此功能可确保年份符合 2000 年之后的年份。

¥Unlike getYear(), the value returned by getUTCFullYear() is an absolute number. For dates between the years 1000 and 9999, getFullYear() returns a four-digit number, for example, 1995. Use this function to make sure a year is compliant with years after 2000.
