Question

我的数组充满了日期。我需要计算所有早于7天且比现在小14天的日期。

示例：

Today is 25/06/2019
Date1: 17/06/2019 - Correct
Date2: 23/06/2019 - Incorrect

为此，我打算使用moment.js

数组中的日期格式为MM / DD / YYYY HH：mm：ss

var res = {sevendays:0};
const morethan7 = moment.utc().add(7, 'day').endOf('day');
const lessthan14 = moment.utc().add(14, 'day').endOf('day');


agedArray.forEach((date)=>{
    var agedtime = moment.utc(date, "MM/DD/YYYY HH:mm:ss");

    if ((agedtime.isBetween(morethan7)) && (agedtime.isBefore(lessthan14)) )
        res.sevendays++;

不幸的是，结果为0。我认为我今天需要指出，但是不知道如何做。

Answer 1

您使用方法.add到达，但您希望使用旧日期。

改为使用.subtract。

例如

const morethan7 = moment().subtract(7, 'day');
const lessthan14 = moment().subtract(14, 'day');

就像@Cid所说的那样，将if条件替换为：

if (agedtime.isBetween(morethan7, lessthan14))

Answer 2

是否有原因，纯JavaScript Array.prototype.filter()对您不起作用？

const src = ['05/20/2019 15:22:58','06/06/2019 16:42:19','06/06/2019 17:33:18','06/07/2019 18:52:09','06/08/2019 09:32:49','06/08/2019 10:25:02','06/10/2019 17:43:22','06/12/2019 19:03:22','06/15/2019 07:28:44','06/15/2019 09:19:34','06/15/2019 07:41:55','06/15/2019 09:57:29','06/15/2019 10:43:41','06/15/2019 11:01:06','06/15/2019 12:11:29','06/15/2019 11:59:45','06/15/2019 12:26:51','06/15/2019 14:20:59','06/17/2019 17:19:41','06/17/2019 17:25:46','06/17/2019 17:29:45','06/17/2019 17:30:49','06/17/2019 17:33:55','06/17/2019 17:07:52','06/17/2019 17:48:49','06/17/2019 18:01:09','06/17/2019 18:24:32','06/17/2019 18:28:32','06/18/2019 17:25:45','06/18/2019 17:37:30','06/18/2019 17:46:49','06/18/2019 17:51:23','06/18/2019 18:05:15','06/18/2019 18:10:21','06/18/2019 18:21:09','06/18/2019 17:54:39','06/18/2019 18:00:57','06/18/2019 18:12:34','06/18/2019 18:13:49','06/18/2019 18:31:27','06/18/2019 19:14:11','06/19/2019 17:06:39','06/19/2019 17:34:16','06/19/2019 17:37:25','06/19/2019 17:05:14','06/19/2019 17:18:30','06/19/2019 17:34:54','06/19/2019 17:43:17','06/19/2019 17:46:32','06/19/2019 17:48:10','06/19/2019 17:50:40','06/20/2019 18:47:59','06/20/2019 19:04:12','06/20/2019 19:09:11','06/20/2019 20:13:04','06/21/2019 17:18:22','06/21/2019 18:38:30','06/22/2019 07:41:11','06/22/2019 07:44:51','06/22/2019 08:16:10','06/22/2019 07:51:27','06/22/2019 07:55:30','06/22/2019 08:01:44','06/24/2019 18:00:12','06/24/2019 17:22:03','06/24/2019 17:23:59','06/24/2019 17:50:38','06/24/2019 17:56:12','06/24/2019 17:58:08','06/24/2019 18:03:22','06/24/2019 18:07:28'];

const res = src.filter(dateStr => (new Date() - new Date(dateStr))>7*86400000 && (new Date() - new Date(dateStr))<14*86400000);

console.log(res);
