javascript - 为什么我的倒计时没有停在 0 处？

Question

//Not finished -- disregard
function evaluate() {
  var cdate = new Date();
  var cday = cdate.getDay();
  var chr = cdate.getHours();
  var cmin = cdate.getMinutes();
  var csec = cdate.getSeconds();
  //Luni
  if (cday === 1) {
    countDown(5, 0, 0, 100, "countdown")
  }
  //Marti sau Miercuri
  if ((cday === 2) || (cday === 3)) {
    countDown(5, 0, 0, 0, "countdown")
  }
  //Joi
  if (cday === 4) {
    countDown(0, 0, 0, 100, "countdown")
  }
  //Vineri sau Sambata
  if ((cday === 5) || (cday === 6)) {
    countDown(5, 0, 0, 0, "countdown")
  }
  //Duminica
  if (cday === 0) {
    countDown(5, 0, 0, 0, "countdown")
  }
}

function countDown(sec, min, hour, day, elem) {
  var element = document.getElementById(elem);
  element.innerHTML = "Urmatorul eveniment este in " + day + " zile " + hour + " ore " + min + " minute " + sec + " secunde.";
  if ((sec === 0) && (min > 0)) {
    sec = 59;
    min = min - 1;
  }
  if ((sec === 0) && (min === 0) && (hour > 0)) {
    sec = 59;
    min = 59;
    hour = hour - 1;
  }
  if ((sec === 0) && (min === 0) && (hour === 0) && (day > 0)) {
    sec = 59;
    min = 59;
    hour = 23;
    day = day - 1;
  }

  if ((min < 0) && (day > 0)) {
    min = 59;
    day = day - 1;
  }
  if ((min < 0) && (day === 0) && (day > 0)) {
    min = 59;
    hour = 23;
    day = day - 1;
  }

  if ((hour < 0) && (day > 0)) {
    hour = 23;
    day = day - 1;
  }
  //Here is the deadline if
  if ((day === 0) && (hour === 0) && (min === 0) && (sec < 0)) {
    clearTimeout(timer);
    elem.innerHTML = "Evenimentul este in decurs!";
  }
  sec--;
  var timer = setTimeout('countDown(' + sec + ',' + min + ',' + hour + ',' + day + ',"' + elem + '")', 1000);
}
evaluate();

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

我的 JavaScript 无法运行。当所有值都达到 0 时，计时器应清除。

我的目标是:评估日期 --> 显示 --> 重置。

if ((day === 0) && (hour === 0) && (min === 0) && (sec < 0)) {
    clearTimeout(timer);
}

有人可以帮我解决这个问题吗？ 我已经设置了一个代码片段。预先感谢您。

您需要将条件更改为sec <= 0并减少 else 内的秒数声明

if ((day === 0) && (hour === 0) && (min === 0) && (sec <= 0)) {
    clearTimeout(timer);
    elem.innerHTML = "Evenimentul este in decurs!";
  }else{
    sec--;
    var timer = setTimeout('countDown(' + sec + ',' + min + ',' + hour + ',' + day + ',"' + elem + '")', 1000);
}
