为什么 Moment isBetween 不起作用？结果是假的

Question

为什么 Moment isBetween 不起作用？ moment(obj.date).isBetween 返回错误。

let dates = [
    {date:'11/26/2020'},
    {date:'11/26/2020'},
    {date:'11/27/2020'},
  ];

let filtered_data = _.filter(dates, (obj)=>{
  console.log(moment(moment(obj.date).format('YYYY-MM-DD')).isBetween('2020-11-25', '2020-11-26'));
  console.log(moment(obj.date).format('YYYY-MM-DD'));
  return moment(obj.date).isBetween('2020-11-25', '2020-11-25');
}); 

console.log(filtered_data);

Answer 1

通过这种方式从字符串 MM-DD-YYYY 中获取你的日期

moment(obj.date, 'MM-DD-YYYY')

var data = [
    {date:'11/26/2020'},
    {date:'11/27/2020'},
    {date:'11/28/2020'}
  ];

let filtered_data = data.filter(obj => {
  let dateToCompare = moment(obj.date, 'MM-DD-YYYY');
  return dateToCompare.isBetween('2020-11-25', '2020-11-28');
}); 

console.log(filtered_data);

Answer 2

Moment JS isBetween 仅在今天之间检查。

例如：-

dates = [{date:'11/26/2020'},{date:'11/26/2020'},{date:'11/27/2020'}];
let filtered_data = dates.filter((obj)=>moment(obj.date).isBetween('2020-11-25',
'2020-11-27'));

输出：-

[{"date":"11/26/2020"},{"date":"11/26/2020"}]

Answer 3

 let filtered_data = _.filter((obj: any) => {
  console.log(moment(moment(obj.date).format('YYYY-MM-DD')).isBetween('2020-11-25', '2020-11-26', undefined, '[]'));
  console.log(moment(obj.date).format('YYYY-MM-DD'));
  return moment(moment(obj.date).format('YYYY-MM-DD')).isBetween('2020-11-25', '2020-11-26', undefined, '[]');
});

这是其他例子

moment('2016-10-30').isBetween('2016-10-30', '2016-12-30', undefined, '()'); //false
moment('2016-10-30').isBetween('2016-10-30', '2016-12-30', undefined, '[)'); //true
moment('2016-10-30').isBetween('2016-01-01', '2016-10-30', undefined, '()'); //false
moment('2016-10-30').isBetween('2016-01-01', '2016-10-30', undefined, '(]'); //true
moment('2016-10-30').isBetween('2016-10-30', '2016-10-30', undefined, '[]'); //true
