1、直接copy去调试
export function getTheSpecifiedDate(date, theOtherDay) {
let myDate = new Date(date); //获取今天日期
myDate.setDate(myDate.getDate() - theOtherDay); //获取指定前几天的日期
const Y = myDate.getFullYear()
const M = myDate.getMonth() + 1 < 10 ? '0' + (myDate.getMonth() + 1) : myDate.getMonth() + 1
const D = myDate.getDate()
let dateGet = `${
Y}-${
M}-${
D}`
return dateGet
}
