如何检查当前时间位于两个给定时间之间答案

【问题标题】：How to check current time lies between two given time Moment如何检查当前时间位于两个给定时间之间
【发布时间】：2021-06-18 08:08:39
【问题描述】：

我正在尝试检查时间是否介于两次之间或不使用片刻。我试过这样

import * as moment from 'moment';

current_day_time.current_time = 2021-06-18T08:03Z
batch_info.batch_start_time = 2021-06-17T03:30:29.351Z,
batch_info.batch_end_time = 2021-06-17T12:30:32.191Z


 const current_time = moment(current_day_time.current_time);
 const start = moment(batch_info.batch_start_time);
 const end = moment(batch_info.batch_end_time);


 
current = Fri Jun 18 2021 13:32:00 GMT+0530
start = Thu Jun 17 2021 09:00:29 GMT+0530
end = Thu Jun 17 2021 18:00:32 GMT+0530

 console.log(moment(current_time).isBetween(start, end)); // false

我们可以清楚地看到 9-18 之间有 13 个谎言，但我还是错了。我怎样才能只比较时间？

【问题讨论】：

Jun 18 不属于Jun 17 的两个日期之间。
我只是想比较一下时间@Mr_Green。

【解决方案1】：

您也可以使用 javascript 方法进行检查。它将以秒为单位返回您的日期时间，然后您可以比较它们，因为它们将以数字的形式出现。例如，看图片：

新日期(your_date).getTime()

import * as moment from 'moment';

current_day_time.current_time = 2021 - 06 - 18 T08: 03 Z
batch_info.batch_start_time = 2021 - 06 - 17 T03: 30: 29.351 Z,
  batch_info.batch_end_time = 2021 - 06 - 17 T12: 30: 32.191 Z


const current_time = moment(current_day_time.current_time);
const start = moment(batch_info.batch_start_time);
const end = moment(batch_info.batch_end_time);

current = Fri Jun 18 2021 13: 32: 00 GMT + 0530
start = Thu Jun 17 2021 09: 00: 29 GMT + 0530
end = Thu Jun 17 2021 18: 00: 32 GMT + 0530


let current_d = new Date("Fri Jun 18 2021 13:32:00 GMT+0530").getTime()
let start_d = new Date("Thu Jun 17 2021 09:00:29 GMT+0530").getTime()
let end_d = new Date("Thu Jun 17 2021 18:00:32 GMT+0530").getTime()

if (current_d > start_d && current_d < end_d) {
  console.log('In')
}

//console.log(moment(current_time).isBetween(start, end)); // false

【解决方案2】：

const format = 'hh:mm:ss'

// const time = moment() gives you current time. no format required.
const time = moment('09:34:00',format);
const beforeTime = moment('08:34:00', format);
const afterTime = moment('10:34:00', format);

if (time.isBetween(beforeTime, afterTime)) {
  console.log('is between')
} else {
  console.log('is not between')
}

我想您比较完整的日期，在这种情况下，从 2021 年 6 月 18 日开始的时间永远不会介于 2021 年 6 月 17 日的两个日期之间。如果不使用moment.js，也许下一个sn-p 是一个想法？

let startTime = new Date('2021-06-17T03:30:29.351Z');
let endTime = new Date('2021-06-17T12:30:32.191Z');
let currentTime = new Date('2021-06-18T08:03Z');

console.log(timeWithin(currentTime, startTime, endTime));

const compareTimes = TimeComparerFactory()
console.log(compareTimes(currentTime, startTime, endTime));

// time comparison for complete dates
function timeWithin(time, start, end) {
  return time > start && time < end;
}

// time comparison for time only
// where the time of a date is converted to a number
// (disregarding milliseconds)
function TimeComparerFactory() {
  const pad = v => `${v}`.padStart(2, `0`);
  const t2Nr = date => {
    const dStr = date.toISOString();
    return +( dStr.split("T")[1].split(/[:+-.]/, 3).map(pad).join("") );
  };
  
  return (time, start, end) => {
    time = t2Nr(time);
    return time > t2Nr(start) && time < t2Nr(end);
  }
}
