效果：

概述：
總共是兩個js文件

date.js----獲取周一到周日的日期和星期

nongli.js----日期轉換農歷

**

目前網上搜到的很多的轉農歷只支持到2020年，2020年以后的算出來不準，我這個是支持1900年-2100年區間內的公歷、農歷互轉， 所以可放心使用

**

獲取周一到周日的日期和星期：
js文件：
date.js

// 根據所選日期獲取一周的日期和星期 export const dateTime = (data) => {//根據日期獲取本周周一~周日的年-月-日var weekList = [];var date = new Date(data);//判斷本日期是否為周日，獲取本周一日期if (date.getDay() == "0") {date.setDate(date.getDate() - 6);} else {date.setDate(date.getDate() - date.getDay() + 1);}var myDate = date.getDate();var myMonth = date.getMonth() + 1;if (date.getDate() < 10) {myDate = '0' + myDate;}if (date.getMonth() + 1 < 10) {myMonth = '0' + myMonth;}// weekList.push(date.getFullYear() + "-" + myMonth+ "-" + myDate);weekList.push({dates: date.getFullYear() + "-" + myMonth + "-" + myDate,day: myDate});// 獲取周二以后日期for (var i = 0; i < 6; i++) {date.setDate(date.getDate() + 1);myDate = date.getDate();myMonth = date.getMonth() + 1;if (date.getDate() < 10) {myDate = '0' + myDate;}if (date.getMonth() + 1 < 10) {myMonth = '0' + myMonth;}weekList.push({dates: date.getFullYear() + "-" + myMonth + "-" + myDate,day: myDate});}let arr = [{week: '一',date: weekList[0].day,dates: weekList[0].dates},{week: '二',date: weekList[1].day,dates: weekList[1].dates},{week: '三',date: weekList[2].day,dates: weekList[2].dates},{week: '四',date: weekList[3].day,dates: weekList[3].dates},{week: '五',date: weekList[4].day,dates: weekList[4].dates},{week: '六',date: weekList[5].day,dates: weekList[5].dates},{week: '日',date: weekList[6].day,dates: weekList[6].dates}]console.log(arr, 'arr')return arr }
