javascript - 明年倒计时不会重置

Question

我们有圣诞节倒计时，但现在显示已过期，而不是重置到明年

// Set the date we're counting down to
var year = new Date().getFullYear();
var countDownDate = new Date("Dec 24, " + year + " 23:00:00").getTime();

// Update the count down every 1 second
var x = setInterval(function() {

  // Get today's date and time
  var now = new Date().getTime();

  // Find the distance between now and the count down date
  var distance = countDownDate - now;

  // Time calculations for days, hours, minutes and seconds
  var days = Math.floor(distance / (1000 * 60 * 60 * 24));
  var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
  var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
  var seconds = Math.floor((distance % (1000 * 60)) / 1000);

  // Display the result in the element with id="clock"
  document.getElementById("clock").innerHTML = days + " days " + hours + "hrs. " + minutes + "mins. " + seconds + "secs. ";

  // If the count down is finished, write some text
  if (distance < 0) {
    clearInterval(x);
    document.getElementById("clock").innerHTML = "EXPIRED";
  }
}, 1000);

“过期”消息可能会在 12 月 25 日至 26 日期间显示，然后重置为 27 日直至明年？

Answer 1

我看不到你在哪里检查你的日期是否晚于 12 月 26 日，这里应该是这样的代码

if (days < -2) {
  countDownDate = new Date("Dec 24, " + (year + 1) + " 23:00:00").getTime();
} else if (distance < 0) {
  clearInterval(x);
  document.getElementById("clock").innerHTML = "EXPIRED";
}

或者最好从一开始就写

var now = new Date()
var year = now.getFullYear() + (now.getMonth() == 11 && now.getDate() > 26)
