两个日期之间的差异，以分钟、小时为单位 javascript

我想找出两个日期之间的差异。我试过这段代码，但它给了我错误的值。我想获得两个日期之间的总分钟数，所以我将小时转换为分钟并添加到分钟。

var hourDiff = timeEnd - timeStart;
var diffHrs = Math.round((hourDiff % 86400000) / 3600000);
var diffMins = Math.round(((hourDiff % 86400000) % 3600000) / 60000);
diffMins = diffMins + (diffHrs * 60);

这里timeEnd Mon Jan 01 2007 11:30:00 GMT+0530 (India Standard Time)，

timeStart Mon Jan 01 2007 11:00:00 GMT+0530 (India Standard Time).

在这里，如果小时差异我得到1，它应该是0和分钟，我得到30这是正确的。但是时间应该0.我在这里做错了什么吗？

试试这段代码（使用 ms 作为初始单位）

var timeStart = new Date("Mon Jan 01 2007 11:00:00 GMT+0530").getTime();
var timeEnd = new Date("Mon Jan 01 2007 11:30:00 GMT+0530").getTime();
var hourDiff = timeEnd - timeStart; //in ms
var secDiff = hourDiff / 1000; //in s
var minDiff = hourDiff / 60 / 1000; //in minutes
var hDiff = hourDiff / 3600 / 1000; //in hours
var humanReadable = {};
humanReadable.hours = Math.floor(hDiff);
humanReadable.minutes = minDiff - 60 * humanReadable.hours;
console.log(humanReadable); //{hours: 0, minutes: 30}

尝试：

var diffHrs = Math.floor((hourDiff % 86400000) / 3600000);

Math.round将0.5小时差四舍五入为 1 .您只想在小时变量中获取"完整"小时数，是否使用Math.floor() <</p>

div class="one_answers" 从变量中删除所有分钟>

试试这个：

var startDate = new Date('Jan 01 2007 11:00:00');
var endDate = new Date('Jan 01 2007 11:30:00');
var starthour = parseInt(startDate.getHours());
var endhour = parseInt(endDate.getHours());
if(starthour>endhour){
    alert('Hours diff:' + parseInt(starthour-endhour));
}
else{
    alert('Hours diff:' + parseInt(endhour-starthour));
}

这是工作小提琴。

如果您确信差异将小于 24 小时，则以下方法有效。

var timeStart= new Date('2015-01-01 03:45:45.890');
var timeEnd = new Date('2015-01-01 05:12:34.567');
var timeDiff = new Date(timeEnd.getTime() - timeStart.getTime());
var humanTime = timeDiff.toISOString().substring(11, 23);
var diffHours = timeDiff.toISOString().substring(11, 12);

humanTime 是 01：

26：48.677，diffHours 是 01

你可以

试试这个：-

function diff_hours(dt2, dt1) 
 {
  var diff =(dt2.getTime() - dt1.getTime()) / 1000;
  diff /= (60 * 60);         // For Hours
  //diff /= (60);          For Minutes
  return Math.abs(Math.round(diff));
 }
dt1 = new Date(2014,10,2);
dt2 = new Date(2014,10,3);
console.log(diff_hours(dt1, dt2));            // you will get '24' hours

dt1 = new Date("October 13, 2014 08:11:00");
dt2 = new Date("October 13, 2014 11:13:00");
console.log(diff_hours(dt1, dt2));           // you will get '3' hours

var timeDiff = function (date1, date2) {
        var a = new Date(date1).getTime(),
            b = new Date(date2).getTime(),
            diff = {};
        diff.milliseconds = a > b ? a % b : b % a;
        diff.seconds = diff.milliseconds / 1000;
        diff.minutes = diff.seconds / 60;
        diff.hours = diff.minutes / 60;
        diff.days = diff.hours / 24;
        diff.weeks = diff.days / 7;
        return diff;
    }

您可以使用以下命令获得以小时分钟为单位的时差和倒计时等秒数：

var diff = EndedTime - StartedTime;
var hours   = Math.floor(diff / 3.6e6);
var minutes = Math.floor((diff % 3.6e6) / 6e4);
var seconds = Math.floor((diff % 6e4) / 1000);
var duration = hours+":"+minutes+":"+seconds;

希望这有帮助。谢谢

您可以获得小时和分钟格式的时差，如下所示

const startTime = new Date(event.startTime);
const endTime = new Date(event.endTime);
const diff = endTime.getTime() - startTime.getTime();
const hrDiff = diff / 3600 / 1000; // 1.555555
const totalHours = parseFloat((hrDiff).toFixed(2)); // 1.5
