js实现日期农历与公历的互转

使用年限：1900-2100

使用场景1：vue项目

js引入：import calendar from '../../utils/calendar.js'

方法调用：

getNowDate(){var nowDate = new Date()// 输入公历年月日，得出农历信息var nongliStr = calendar.calendarFormatter.solar2lunar(nowDate.getFullYear(), nowDate.getMonth() + 1, nowDate.getDate());// 输入农历年月日，得出公历信息// var gongliStr  = calendar.calendarFormatter.lunar2solar(2019, 11, 7, false))},

具体js文件calendar.js：

/**
* @1900-2100区间内的公历、农历互转
* @charset UTF-8
* @Author  jiangjiazhi
* @公历转农历：calendar.solar2lunar(1987,11,01); //[you can ignore params of prefix 0]
* @农历转公历：calendar.lunar2solar(1987,09,10); //[you can ignore params of prefix 0]
*//**
