1.比較大小
function compareDate(dateTime1,dateTime2) {
let formatDate1 = new Date(dateTime1)
let formatDate2 = new Date(dateTime2)
if(formatDate1 > formatDate2) {
// let date1 = formatDate1.getFullYear() + '-' + (formatDate1.getMonth() + 1) + '-' + formatDate1.getDate()
return true
}else {
// let date2 = formatDate2.getFullYear() + '-' + (formatDate2.getMonth() + 1) + '-' + formatDate2.getDate()
return false
}
}
console.log(compareDate('2020-12-02','2020-12-01'))
2.和當前的時間相差多少天
function getDate(date) {
let nowTime = new Date()
let oldTime = new Date(date)
let reduceDate = Math.ceil((oldTime.getTime() - nowTime.getTime()) / 86400000)
return reduceDate
}
console.log(getDate('2020-3-13'))
