JavaScript 使用正确格式时计时器日期无效

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)

第一个警报显示为 "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'，
day cookie reads '11',
hour cookie reads '1',
minute cookie reads '11',
ampm cookie reads 'PM'.",
第四个警报说 "Timer offset is NaN".

我必须使用不同的格式吗？

Answer 1

这样：

您希望使用 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()
  ;
