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

var __startTime = moment("2016-06-06T09:00").format();
var __endTime = moment("2016-06-06T21:00").format();

var __duration = moment.duration(moment(__endTime).diff(__startTime));
var __hours = __duration.asHours();
console.log(__hours);

其他回答

 var start=moment(1541243900000);
 var end=moment(1541243942882);
 var duration = moment.duration(end.diff(startTime));
 var hours = duration.asHours();

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。

也许对某人有用

          var ax = moment(
            new Date().toLocaleString(), // today/now is 09/12/2021 10:00:00
            "DD/MM/YYYY HH:mm:ss"
            ).diff(
              moment(
                "12/11/2022 13:43:11", // some time in future or past
                "DD/MM/YYYY HH:mm:ss"
              )
          );
          console.log('if today is in the future of the compared date then 
          result should be negative ==>', ax);
          // ax bigger than 0 zero means date in past. ms less than zero is in future

我知道这很老了,但这里有一个简单的解决方案:

const hourDiff = start.diff(end, "hours");

开始和结束都是力矩对象。

享受吧!

我知道这个问题已经回答了,但如果你想要递归的更通用的东西,不依赖于moment fromNow,你可以使用我创建的这个函数。当然,您可以根据需要更改其逻辑,使其支持年和秒。

var createdAt = moment('2019-05-13T14:23:00.607Z');
var expiresAt = moment('2019-05-14T14:23:00.563Z');

// You can also add years in the beginning of the array or seconds in its end
const UNITS = ["months", "weeks", "days", "hours", "minutes"]
function getValidFor (createdAt, expiresAt, unit = 'months') {
    const validForUnit = expiresAt.diff(createdAt, unit);
    // you could adjust the if to your needs 
    if (validForUnit > 1 || unit === "minutes") {
    return [validForUnit, unit];
  }
  return getValidFor(createdAt, expiresAt, UNITS[UNITS.indexOf(unit) + 1]);
}

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

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>
