IsBetween

IsBetween 添加了 .isBetween() API 以返回 boolean 指示日期是否在其他两个日期之间。

var isBetween = require("dayjs/plugin/isBetween");
// import isBetween from 'dayjs/plugin/isBetween' // ES 2015

dayjs.extend(isBetween);

// To use `year` granularity pass the third parameter
dayjs("2010-10-20").isBetween("2010-10-19", dayjs("2010-10-25"), "year");

// Parameter 4 is a string with two characters; '[' means inclusive, '(' exclusive
// '()' excludes start and end date (default)
// '[]' includes start and end date
// '[)' includes the start date but excludes the stop
// Granuality offers the precision on start and end inclusive checks.
// For example including the start date on day precision you should use 'day' as 3rd parameter.
dayjs("2016-10-30").isBetween("2016-01-01", "2016-10-30", "day", "[)");
