Question

我想计算Date.parse生成的两个时间戳之间的小时数和分钟数。在我得到差异后，我需要将其转换为小时和分钟，如2.10（意味着，2小时10分钟）。一旦我读完了它就需要将它除以3600，所以我尝试了这段代码，但它只是给了我0.89而不是1.26。

var now = new Date();
var endTime = Date.parse(now)/1000;
var startTime = Date.parse("2018-03-16 10:29:17")/1000;

$scope.timestamp_difference = startTime - endTime;
$scope.hours = $scope.timestamp_difference/3600;

如何正确做到？

Answer 1

如果你还没有听说过，Momentjs在javascript中使用日期和时间非常容易我更新了代码，你可能希望它现在可以帮到你

var date1 = moment('03/15/2018 11:00', 'MM/DD/YYYY hh:mm'),
   date2 = moment('03/16/2018 10:00', 'MM/DD/YYYY hh:mm');

 var duration = moment.duration(date2.diff(date1));
//you will get 23 hours 00 minute
  alert(duration.asHours().toFixed(2))

  Output: 23:00 hrs

Answer 2

function getTimeDifference(timestampDifference) {
    var hours = ~~(timestampDifference / 3600);
    var minuts = ~~((timestampDifference - hours * 3600) / 60);
    var seconds = timestampDifference - hours * 3600 - minuts * 60;
    return hours + '.' + minuts + '.' + seconds;
}

Answer 3

var minutes = "0" + Math.floor(timestampDifference / 60);
//  get minutes
var seconds = "0" + Math.floor(timestampDifference - minutes * 60);
// get seconds
var hour = "0" + Math.floor(timestampDifference / 3600);
//get hour
if ( hour > 1 ) { 
    return hour.substr(-2) + ":" + minutes.substr(-2) + ":" + seconds.substr(-2);
} else {
    return minutes.substr(-2) + ":" + seconds.substr(-2);
}
// check if the hour is greater then 1 than return time with hour else return minutes.

如何在angularjs中将时间戳转换为小时和分钟？
