为什么我的倒计时功能不起作用？

Question

我对圣诞节感到非常兴奋，所以我决定有什么比创建一个圣诞节倒数计时器更好的倒数方式。但是我的倒计时似乎不起作用。


let targetDate = new Date(null, 11, 31, 0, 0, 0, 0)

let today = new Date()

targetDate.setFullYear(today.getFullYear())

if (targetDate.getTime() - today.getTime() <= 0) {

    targetDate.setFullYear(today.getFullYear() + 1)

}

let timer = setInterval(() => {

    today = new Date()

    e = document.getElementById("countdown")

    if (targetDate.getTime() - today.getTime() == 0) {

        e.innerHTML = "Horray! Merry Christmas, Everyone! Horray!"

        clearInterval(timer)

    } else {

        distance = targetDate.getTime() - today.getTime()

        days = Math.floor(distance / (24 * 60 * 60 * 1000))

        distance -= day * 24 * 60 * 60 * 1000

        hours = Math.floor(distance / (60 * 60 * 1000))

        distance -= hours * 60 * 60 * 1000

        minutes = Math.floor(distance / (60 * 1000))

        distance -= minutes * 60 * 1000

        seconds = Math.floor(distance / 1000)

        e.innerHTML = days + " d " hours + " h " + minutes + " m " + seconds + " s "

    }

}, 1000)

我试过控制台记录定时器值，但代码没有呈现。 innerHTML 代码似乎没有运行.

看看这一行

 e.innerHTML = days + " d " hours + " h " + mi

应该是

 e.innerHTML = days + " d " + hours + " h " + mi
