获取剩余天数(小时/分钟)的问题.与当下约会

Question

我的应用程序中有两个函数，一个是获取我选择的下一个工作日的实例(例如，下周四获取(，然后我有一个函数，可以计算回忆天数、小时、分钟和秒。

到目前为止，我可以得到剩余的天数，但小时、分钟和秒显示为0。这是因为当我下周四的日期没有所需的时间戳格式时：

nextThursday "2022-03-24T15:11:48.580Z"
LOG  Days:  5.999999745370371
LOG  Hours:  0
LOG  Minutes:  0
LOG  Seconds:  0

我怎么能在得到的时间戳上加上小时和分钟(00:00(，我想这就是问题所在！

let nextThursday = getNextThursday();
getCountdown();
const getNextThursday = () =>
{
const dayINeed = 4; // for Thursday
const today = moment().isoWeekday();
// if we haven't yet passed the day of the week that I need:
if (today <= dayINeed) { 
// then just give me this week's instance of that day
return moment().isoWeekday(dayINeed);
} else {
// otherwise, give me *next week's* instance of that same day
return moment().add(1, 'weeks').isoWeekday(dayINeed);
}
};
const getCountdown = (ending) =>
{
var now = moment();
var end = moment(ending); // another date
var duration = moment.duration(end.diff(now));
//Get Days and subtract from duration
var days = duration.asDays();
duration.subtract(moment.duration(days,'days'));
//Get hours and subtract from duration
var hours = duration.hours();
duration.subtract(moment.duration(hours,'hours'));
//Get Minutes and subtract from duration
var minutes = duration.minutes();
duration.subtract(moment.duration(minutes,'minutes'));
//Get seconds
var seconds = duration.seconds();
console.log("Days: ",days);
console.log("Hours: ",hours);
console.log("Minutes: ",minutes);
console.log("Seconds: ",seconds);
};

Answer 1

您的问题是使用asDays()，它将您的持续时间转换为十进制数(包括十进制部分的小时、分钟和秒(

并且您不需要在每次减法中调用moment.duration(x,'x')

修复应该是

const getCountdown = (ending) => {
var now = moment();
var end = moment(ending); // another date
var duration = moment.duration(end.diff(now));
//Get Days and subtract from duration
var days = duration.days();
duration.subtract(days, 'days');
//Get hours and subtract from duration
var hours = duration.hours();
duration.subtract(hours, 'hours');
//Get Minutes and subtract from duration
var minutes = duration.minutes();
duration.subtract(minutes, 'minutes');
//Get seconds
var seconds = duration.seconds();
console.log("Days: ", days);
console.log("Hours: ", hours);
console.log("Minutes: ", minutes);
console.log("Seconds: ", seconds);
};
