javascript - 时刻 isBetween 使用格式不起作用？

Question

我设置了 3 个日期，开始、结束和今天。

let start_date = '20-06-2018',
end_date = '20-06-2018',
today = '20-06-2018'

但是当我解析字符串并使用 isBetween 时，它返回 false。

console.log(moment(start_date, 'DD-MM-YYYY').isBetween(moment(today, 'DD-MM-YYYY'), moment(end_date, 'DD-MM-YYYY'))) //false?

虽然开始和结束是同一天，但今天应该是isBetweeen。

Answer 1

参见 isBetween文档和使用包容性参数

Check if a moment is between two other moments, optionally looking at unit scale (minutes, hours, days, etc). The match is exclusive.

Version 2.13.0 introduces inclusivity. A [ indicates inclusion of a value. A ( indicates exclusion. If the inclusivity parameter is used, both indicators must be passed.

let start_date = '20-06-2018',
end_date = '20-06-2018',
today = '20-06-2018'

console.log(moment(start_date, 'DD-MM-YYYY').isBetween(moment(today, 'DD-MM-YYYY'), moment(end_date, 'DD-MM-YYYY')))

console.log(moment(start_date, 'DD-MM-YYYY').isBetween(moment(today, 'DD-MM-YYYY'), moment(end_date, 'DD-MM-YYYY'), null, '[]'))
