首先,我们要创建一个变量total以保留到截止日期为止的剩余时间。Date.parse()函数将时间字符串转换为毫秒值,这样我们就可以将两次相减,得到中间的时间量。 consttotal=Date.parse(endtime)-Date.parse(newDate()); 4.将时间转换为可用格式 现在我们要将毫秒转换为天,小时,分钟和秒。让我们以秒为例: ...
Date Conversion from calendar date to epoch timestamp uses the standard Go library which usesint, rather thanfloatas per ECMAScript specification. This means if you pass arguments that overflow int to theDate()constructor or if there is an integer overflow, the result will be incorrect, for ex...

两个Date相减能得到毫秒,那理所当然地某个Date加上毫秒数就可以等于另一个日期了。例如 2020-01-01 加上 86400000 毫秒,就等于 2020-01-02。 No!No!No! newDate(2020,0,1)+86400000//Wed Jan 01 2020 00:00:00 GMT+0800 (China Standard Time)86400000 ...
