Javascript 每个地区的人都一样的倒计时

Question

目前我有一个倒数计时器，唯一的问题是我输入的日期和时间不会与住在其他地方的人同时结束，javascript 会被解释为他们的时区.有什么办法可以解决这个问题吗？当前脚本：

var countDownDate = new Date("Jul 30, 2020 20:00:00").getTime();


var x = setInterval(function() {


  var now = new Date().getTime();


  var distance = countDownDate - now;


  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);


  document.getElementById("countdown").innerHTML = days + "d " + hours + "h "
  + minutes + "m " + seconds + "s ";


  if (distance < 0) {
    clearInterval(x);
    document.getElementById("countdown").innerHTML = "EXPIRED";
  }
}, 1000);

<p id="countdown"></p>

Answer 1

为您的字符串添加明确的时区（例如 UTC-0000）

// Add an explicit timezone to your string (eg. UTC-0000)
var countDownDate = new Date("Jul 30, 2020 20:00:00 UTC-0000").getTime();


var x = setInterval(function() {


  var now = new Date().getTime();


  var distance = countDownDate - now;


  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);


  document.getElementById("countdown").innerHTML = days + "d " + hours + "h "
  + minutes + "m " + seconds + "s ";


  if (distance < 0) {
    clearInterval(x);
    document.getElementById("countdown").innerHTML = "EXPIRED";
  }
}, 1000);
