为了消除任何混淆,建议使用new Date(year, month, day, hours, minutes, seconds, milliseconds)格式来创建日期,这是使用Date构造函数时能够做到的最明确的方式。 可以使用允许省略最后四个参数的变体,如果它们为零;例如,new Date(2012, 10, 12)与new Date(2012, 10, 12, 0, 0, 0, 0)是相同的,因为未指定...
Parses a date-string and returns milliseconds since the epoch. You'll probably want to usenew XDate(dateString)instead. XDate.now() Returns the current date, as milliseconds since the epoch. You'll probably want to usenew XDate()instead. XDate.today() Returns the current date with time cle...
It adds the specified number of years ('n') to the current year of the Date object. The "setFullYear()" method updates the year part of the date and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC, representing the updated date. After defining the function, the...
