如何计算此语句

var dateTo = new Date(2019,04,03,3,15,0);
var countdown = Math.round((dateTo.getTime() - new Date().getTime()) / 1000);

Answer 1

该值不是您所期望的吗？尝试打印日期，并确保该值是您想要的值：

var dateTo = new Date(2019,04,03,3,15,0);
console.log(dateTo);

此外，最好只使用4和3，而不要使用“ 04”和“ 03”。

Answer 2

这是你要去的吗？

#// Set the date we're counting down to
    var countDownDate = new Date("Jan 5, 2021 15:37:25").getTime();

  // Get todays 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));


  console.warn("val", days);
