日期处理，转换

68 阅读 0 评论 45 点赞

我是靠谱客的博主聪明云朵，最近开发中收集的这篇文章主要介绍日期处理，转换，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

例如：将日期转换成天干地支

1.引入文件

// 引入文件
import calendars from "./calendars.js";

2.调用对应方法并传入参数

let ganzhi = calendars.calendar.solar2lunar(2022,4,9);
console.log(ganzhi);
console.log(ganzhi.gzYear, ganzhi.gzMonth, ganzhi.gzDay);
// 得到壬寅 甲辰 壬辰

附件：calendars.js
