如果我有两个日期,如何使用JavaScript在分钟内得到两个日期之间的差异?


当前回答

你可以签出这段代码:

var today = new Date(); var Christmas = new Date(today.getFullYear() + “-12-25”); var diffMs = (圣诞节 - 今天);从现在到圣诞节之间的毫秒数 var diffDays = Math.floor(diffMs / 86400000);日 var diffHrs = Math.floor((diffMs % 86400000) / 3600000);小时 var diffMins = Math.round((((diffMs x86400000) % 3600000) / 60000);纪要 console.log(diffDays + “ days, ” + diffHrs + “ hours, ” + diffMins + “ minutes till Christmas =)”);

或者var diffMins = Math.floor((…如果不想舍入分钟,则丢弃秒。

这是我在节点中求解类似问题时得到的一些乐趣。

function formatTimeDiff(date1, date2) {
  return Array(3)
    .fill([3600, date1.getTime() - date2.getTime()])
    .map((v, i, a) => {
      a[i+1] = [a[i][0]/60, ((v[1] / (v[0] * 1000)) % 1) * (v[0] * 1000)];
      return `0${Math.floor(v[1] / (v[0] * 1000))}`.slice(-2);
    }).join(':');
}

const millis = 1000;
const utcEnd = new Date(1541424202 * millis);
const utcStart = new Date(1541389579 * millis);
const utcDiff = formatTimeDiff(utcEnd, utcStart);

console.log(`Dates:
  Start   : ${utcStart}
  Stop    : ${utcEnd}
  Elapsed : ${utcDiff}
  `);

/*
Outputs:

Dates:
  Start   : Mon Nov 05 2018 03:46:19 GMT+0000 (UTC)
  Stop    : Mon Nov 05 2018 13:23:22 GMT+0000 (UTC)
  Elapsed : 09:37:02

你可以签出这段代码:

它很容易工作:

var endTime = $("#ExamEndTime").val();
var startTime = $("#ExamStartTime").val();

//create date format          
var timeStart = new Date("01/01/2007 " + startTime);
var timeEnd = new Date("01/01/2007 " + endTime);
                
var  msInMinute = 60 * 1000;

var difference =  Math.round(Math.abs(timeEnd - timeStart) / msInMinute);

$("#txtCalculate").val(difference);

您可以进行如下操作:

获取日期的差异(以毫秒为单位) 将毫秒转换为分钟i-e ms/1000/60

代码:

let dateOne = new Date("2020-07-10");
let dateTwo = new Date("2020-07-11");

let msDifference =  dateTwo - dateOne;
let minutes = Math.floor(msDifference/1000/60);
console.log("Minutes between two dates =",minutes);

下面的代码对我有用,

function timeDiffCalc(dateNow,dateFuture) {
    var newYear1 = new Date(dateNow);
    var newYear2 = new Date(dateFuture);

        var dif = (newYear2 - newYear1);
        var dif = Math.round((dif/1000)/60);
        console.log(dif);

}
