我可以使用MomentJs得到两个日期之间的差异,如下所示:

moment(end.diff(startTime)).format("m[m] s[s]")

但是,我还想在适用的情况下显示小时(仅当>= 60分钟已经过时)。

然而,当我试图检索持续时间小时使用以下:

var duration = moment.duration(end.diff(startTime));
var hours = duration.hours();

它返回当前的小时数,而不是两个日期之间的小时数。

我如何得到两个时刻之间的小时差?


当前回答

或者你可以简单地做:

var a = moment('2016-06-06T21:03:55');//now
var b = moment('2016-05-06T20:03:55');

console.log(a.diff(b, 'minutes')) // 44700
console.log(a.diff(b, 'hours')) // 745
console.log(a.diff(b, 'days')) // 31
console.log(a.diff(b, 'weeks')) // 4

你只需要在moment.js中使用date.diff()方法

Const now = moment.utc(); Var end = moment("2021-09-13"); Var days =现在。diff(结束,“天”); console.log(天) < script src = " https://momentjs.com/downloads/moment.js " > < /脚本> < script src = " https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js " > < /脚本>

你很接近了。你只需要使用duration.asHours()方法(请参阅文档)。

var duration = moment.duration(end.diff(startTime));
var hours = duration.asHours();

下面的代码块展示了如何使用MomentJS计算两个日期之间的天数差异。

var now = moment(new Date()); //todays date
var end = moment("2015-12-1"); // another date
var duration = moment.duration(now.diff(end));
var days = duration.asDays();
console.log(days)

如果你想要两个日期之间的总分钟数,下面的代码将帮助你充分开始日期:2018-05-04 02:08:05,结束日期:2018-05-14 09:04:07…

function countDaysAndTimes(startDate,endDate){
return new Promise(function (resolve, reject) {
var dayObj = new Object;
var finalArray = new Array;

var datetime1 = moment(startDate);
var datetime2 = moment(endDate);
if(datetime1.format('D') != datetime2.format('D') || datetime1.format('M') != datetime2.format('M') ||  datetime1.format('YYYY') != datetime2.format('YYYY')){
  var onlyDate1 = startDate.split(" ");
  var onlyDate2 = endDate.split(" ");
  var totalDays = moment(onlyDate2[0]).diff(moment(onlyDate1[0]), 'days')

  // First Day Entry
  dayObj.startDate = startDate;
  dayObj.endDate = moment(onlyDate1[0]).add(1, 'day').format('YYYY-MM-DD')+" 00:00:00";
  dayObj.minutes = moment(dayObj.endDate).diff(moment(dayObj.startDate), 'minutes');
  finalArray.push(dayObj);

  // Between Days Entry
  var i = 1;
  if(totalDays > 1){
    for(i=1; i<totalDays; i++){
      var dayObj1 = new Object;
      dayObj1.startDate = moment(onlyDate1[0]).add(i, 'day').format('YYYY-MM-DD')+" 00:00:00";
      dayObj1.endDate = moment(onlyDate1[0]).add(i+1, 'day').format('YYYY-MM-DD')+" 00:00:00";
      dayObj1.minutes = moment(dayObj1.endDate).diff(moment(dayObj1.startDate), 'minutes');
      finalArray.push(dayObj1);
    }
  }

  // Last Day Entry
  var dayObj2 = new Object;
  dayObj2.startDate = moment(onlyDate1[0]).add(i, 'day').format('YYYY-MM-DD')+" 00:00:00";
  dayObj2.endDate = endDate ;
  dayObj2.minutes = moment(dayObj2.endDate).diff(moment(dayObj2.startDate), 'minutes');
  finalArray.push(dayObj2);

}
else{
  dayObj.startDate = startDate;
  dayObj.endDate = endDate;
  dayObj.minutes = datetime2.diff(datetime1, 'minutes');
  finalArray.push(dayObj);
}
console.log(JSON.stringify(finalArray));
// console.table(finalArray);
resolve(finalArray);
});
}

如您所见,开始日期和结束日期需要是此方法工作的时刻对象。
