以下脚本计算下星期五和下星期日的时间。
问题 :. toISOString的使用使用UTC时间。我需要更改一些输出本地时间的内容。我对javascript非常陌生,因此找不到适合的属性而不是.toIsostring。我该怎么办?
function nextWeekdayDate(date, day_in_week) {
var ret = new Date(date || new Date());
ret.setDate(ret.getDate() + (day_in_week - 1 - ret.getDay() + 7) % 7 + 1);
return ret;
}
let nextFriday = nextWeekdayDate(null, 5);
let followingSunday = nextWeekdayDate(nextFriday, 0);
console.log('Next Friday : ' + nextFriday.toDateString() +
'\nFollowing Sunday: ' + followingSunday.toDateString());
/* Previous code calculates next friday and next sunday dates */
var checkinf = nextWeekdayDate(null, 5);
var [yyyy, mm, dd] = nextFriday.toISOString().split('T')[0].split('-');
var checkouts = nextWeekdayDate(null, 7);
var [cyyy, cm, cd] = followingSunday.toISOString().split('T')[0].split('-');
如果您担心某些时区的日期不正确,请尝试将时间归一化
function nextWeekdayDate(date, day_in_week) {
var ret = new Date(date || new Date());
ret.setHours(15,0,0,0); // normalise
ret.setDate(ret.getDate() + (day_in_week - 1 - ret.getDay() + 7) % 7 + 1);
return ret;
}
let nextFriday = nextWeekdayDate(null, 5);
let followingSunday = nextWeekdayDate(nextFriday, 0);
console.log('Next Friday : ' + nextFriday.toDateString() +
'\nFollowing Sunday: ' + followingSunday.toDateString());
/* Previous code calculates next friday and next sunday dates */
var checkinf = nextWeekdayDate(null, 5);
var [yyyy, mm, dd] = nextFriday.toISOString().split('T')[0].split('-');
var checkouts = nextWeekdayDate(null, 7);
var [cyyy, cm, cd] = followingSunday.toISOString().split('T')[0].split('-');
您担心[yyyy,mm,dd]是使用UTC而不是当前的时区吗?
The nextFriday is a date object. Would it work if you use the get-functions instead?
e.g.
const nextFridayYear = nextFriday.getFullYear();
// get month is zero index based, i have added one
const nextFridayMonth = (nextFriday.getMonth() + 1).toString()
.padStart(2, '0');
const nextFridayDay = today.getDate().toString()
.padStart(2, '0');
