              alert("time has ended");

您需要另一个else条件。

试试这个：

＆＃13;

function countdown(minutes) {
  var seconds = 60;
  var mins = minutes

  function tick() {
    var counter = document.getElementById("timer");
    var current_minutes = mins - 1
    seconds--;
    counter.innerHTML = current_minutes.toString() + ":" + (seconds < 10 ? "0" : "") + String(seconds);
    if (seconds > 0) {
      setTimeout(tick, 1000);
    } else {
      if (mins > 1) {
        setTimeout(function() {
          countdown(mins - 1);
        }, 1000);
      } else {
        alert("time has ended");
      }
    }
  }
  tick();
}

countdown(2);;

＆＃13;

<div id="timer"></div>

＆＃13;

如果时间结束如何提醒
