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
你所需要做的就是把hours作为第二个参数传递给moments diff函数。
var a = moment([21,30,00], "HH:mm:ss")
var b = moment([09,30,00], "HH:mm:ss")
a.diff(b, 'hours') // 12
文档:https://momentjs.com/docs/ # / /显示/不同
例子:
const dateFormat = "YYYY-MM-DD HH:mm:ss"; // Get your start and end date/times const rightNow = moment().format(dateFormat); const thisTimeYesterday = moment().subtract(1, 'days').format(dateFormat); // pass in hours as the second parameter to the diff function const differenceInHours = moment(rightNow).diff(thisTimeYesterday, 'hours'); console.log(`${differenceInHours} hours have passed since this time yesterday`); <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.min.js"> </script>
其他回答
就我而言，我想要的是小时和分钟:
var duration = moment.duration(end.diff(startTime));
var hours = duration.hours(); //hours instead of asHours
var minutes = duration.minutes(); //minutes instead of asMinutes
更多信息请参考官方文档。
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);
});
}

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)
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
