根据两个时间戳计算倒计时
let needDate = endTime -starTime // 计算剩余毫秒值
var dayDiff = Math.floor(needDate / (24 * 3600 * 1000)) // 计算出相差天数
var leave1 = needDate % (24 * 3600 * 1000) // 计算天数后剩余的毫秒数
var dayToHours = dayDiff * 24 // 天数转换成小时
this.myHours = Math.floor(leave1 / (3600 * 1000)) + dayToHours // 计算出小时数
// 计算相差分钟数
var leave2 = leave1 % (3600 * 1000) // 计算小时数后剩余的毫秒数
this.myMinutes = Math.floor(leave2 / (60 * 1000)) // 计算相差分钟数
// 计算相差秒数
var leave3 = leave2 % (60 * 1000) // 计算分钟数后剩余的毫秒数
this.mySeconds = Math.round(leave3 / 1000)
定时器
let authTimetimer = setInterval(() => {
this.mySeconds--
if (this.mySeconds <= -1) {
this.myMinutes--
let setTime = 60
this.mySeconds = setTime
}
if (this.myMinutes <= -1) {
this.myHours--
let setMimutes = 60
this.myMinutes = setMimutes
}
if (this.myHours <= -1) {
clearInterval(authTimetimer)
let overTime = '00'
this.myMinutes = overTime
this.mySeconds = overTime
this.myHours = overTime
return this.myMinutes && this.mySeconds && this.myHours
}
}, 1000)
