计算两个日期之间的差异 - datetimepicker

Question

Select Select start date and hour
然后 > Select end date and hour

我想在 Show Days difference here 和 Show Hours difference here

中显示这两个日期和时间之间的差异

请参阅以下代码段以供参考

$(function() {
  // defualt script for datetimepicket
  $('.startDateTime').datetimepicker({
    
    //uncomment following code to enable debug mode
    //debug: true
  });
  $('.endDateTime').datetimepicker({
    
    //uncomment following code to enable debug mode
    //debug: true,
    
    useCurrent: false
  });
  $(".startDateTime").on("dp.change", function(e) {
    $('.endDateTime').data("DateTimePicker").minDate(e.date);
  });
  $(".endDateTime").on("dp.change", function(e) {
    $('.startDateTime').data("DateTimePicker").maxDate(e.date);
  });
});

Answer 1

首先，对于这两个日期，您必须将此日期格式从日期和小时转换为毫秒。然后找出毫秒之间的差异。

一分钟 60*1000 一小时 60*60*1000 一天 24*60*60*1000

除以这个特定项并完成工作。

Answer 2

您应该尝试使用名为 moment.js -> http://momentjs.com/docs/#/displaying/difference/ 的 javascript 库示例：

var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days') // 1

Answer 3

Demo

JS

function CalcDiff() {
    var a = $('.startDateTime').data("DateTimePicker").date();
    var b = $('.endDateTime').data("DateTimePicker").date();
    var timeDiff = 0
    if (b) {
        timeDiff = (b - a) / 1000;
    }
    var DateDiff = Math.floor(timeDiff / (60 * 60 * 24));
    var BalSecs = timeDiff - (DateDiff * (60 * 60 * 24));
    $('.days-here').val(DateDiff)
    $('.time-here').val(Math.ceil(BalSecs / (60 * 60)))
}

在 dp.change

上调用上述函数

$(".endDateTime").on("dp.change", function (e) {
    $('.startDateTime').data("DateTimePicker").maxDate(e.date);
    CalcDiff()
});

在计算完天数后，您已经计算了小时数，因此逻辑

    var DateDiff = Math.floor(timeDiff / (60 * 60 * 24));
    var BalSecs = timeDiff - (DateDiff * (60 * 60 * 24));
