使用正确格式时，JavaScript计时器日期无效

Question

我有一个字符串，由用户在表单中输入的cookie组合在一起。这是代码：

var monthCookie     = getCookieValue("monthUserPref")
var dayCookie       = getCookieValue("dayUserPref")
var hourCookie      = getCookieValue("hourUserPref")
var minuteCookie    = getCookieValue("minuteUserPref")
var ampmCookie      = getCookieValue("ampmUserPref")
var currentYear     = new Date().getFullYear();
var monthCookie     = getMonth(monthCookie);
var currentEndDateForClockNoTZChange = "'"+currentYear+", "+monthCookie+", "+dayCookie+", "+hourCookie+", "+minuteCookie+", 0'"
var endTimeNoOffset = new Date(currentEndDateForClockNoTZChange)
var endTimeOffset   = endTimeNoOffset.getTimezoneOffset();
alert("Put together time is "+currentEndDateForClockNoTZChange)
alert(endTimeNoOffset)
alert("month cookie reads '"+monthCookie+"', day cookie reads '"+dayCookie+"', hour cookie reads '"+hourCookie+"', minute cookie reads '"+minuteCookie+"', ampm cookie reads '"+ampmCookie+"'.");
alert("timer offset is "+endTimeOffset)

第一个警报读"Put together time is '2022, 1, 11, 1, 11, 0' "，
第二个警报说Invalid Date"，
第三个警报说，month cookie reads '1'，
1day cookie reads '11'，
5hour cookie reads '1'，
2minute cookie reads '11'，
3ampm cookie reads 'PM'."，
>第四个警报说是"Timer offset is NaN"。

我必须使用其他格式吗

Answer 1

这种方式：

使用Date((构造函数的方式是关于整数参数，而不是字符串

let
monthCookie     = Number(getCookieValue('monthUserPref'))
, dayCookie       = Number(getCookieValue('dayUserPref'))
, hourCookie      = Number(getCookieValue('hourUserPref'))
, minuteCookie    = Number(getCookieValue('minuteUserPref'))
, ampmCookie      = Number(getCookieValue('ampmUserPref'))
, currentYear     = new Date().getFullYear()
, monthCookie     = getMonth(monthCookie)
, endTimeNoOffset = new Date( currentYear, monthCookie, dayCookie, hourCookie, minuteCookie, 0 )
, endTimeOffset   = endTimeNoOffset.getTimezoneOffset()
;
