根据所选日期、当前日期计算一周的日期和星期，农历
效果：
概述：
总共是两个js文件
date.js----获取周一到周日的日期和星期
nongli.js----日期转换农历
**
目前网上搜到的很多的转农历只支持到2020年，2020年以后的算出来不准，我这个是支持1900年-2100年区间内的公历、农历互转， 所以可放心使用
**
获取周一到周日的日期和星期：
js文件：
date.js
// 根据所选日期获取一周的日期和星期
export const dateTime = (data) => {
//根据日期获取本周周一~周日的年-月-日
var weekList = [];
var date = new Date(data);
//判断本日期是否为周日，获取本周一日期
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
});
// 获取周二以后日期
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
}
