我怎么才能顺时针做循环倒计时呢？

<div id="countdown"></div>

function countdown() {
  var targetTime = new Date();  // 设置目标时间为当前时间
  targetTime.setSeconds(targetTime.getSeconds() + 60);  // 倒计时60秒

  var countdownElement = document.getElementById("countdown");

  var timer = setInterval(function() {
    var currentTime = new Date();
    var remainingTime = targetTime - currentTime;

    var seconds = Math.floor((remainingTime / 1000) % 60);
    var minutes = Math.floor((remainingTime / 1000 / 60) % 60);
    var hours = Math.floor((remainingTime / (1000 * 60 * 60)) % 24);

    countdownElement.innerHTML = hours + "时 " + minutes + "分 " + seconds + "秒";

    if (remainingTime <= 0) {
      clearInterval(timer);
      countdown();  // 循环倒计时
    }
  }, 1000);
}

countdown();  // 启动倒计时
