是否之间

这指示 Day.js 对象是否位于其他两个提供的日期时间之间。

¥This indicates whether the Day.js object is between two other supplied date-time.

This requires the IsBetween plugin to work

dayjs.extend(isBetween)
dayjs('2010-10-20').isBetween('2010-10-19', dayjs('2010-10-25')) 
// default milliseconds

如果要将粒度限制为毫秒以外的单位，请将其作为第三个参数传递。在这种情况下，比较将尊重给定单位和上述单位。

¥If you want to limit the granularity to a unit other than milliseconds, pass it as the third parameter. In that case the comparision respects the given unit and the units above.

dayjs().isBetween('2010-10-19', '2010-10-25', 'month') // compares month and year

单位不区分大小写，并支持复数和缩写形式。

¥Units are case insensitive, and support plural and short forms.

所有可用单位的列表

¥List of all available units

第四个参数是关于包容性。[ 表示包含一个值。( 表示排除。

¥The fourth parameter is about inclusivity. A [ indicates inclusion of a value. A ( indicates exclusion.

如果使用包容性参数，则必须传递两个指标。

¥If the inclusivity parameter is used, both indicators must be passed.

dayjs('2016-10-30').isBetween('2016-01-01', '2016-10-30', null, '[)')
