        counter.innerHTML = current_minutes.toString() + ":" + (seconds < 10 ? "0" : "") + String(seconds);
        if( seconds > 0 ) { 
            setTimeout(tick, 1000);

        } else {

               // countdown(mins-1);   never reach “00″ issue solved:Contributed by Victor Streithors
               setTimeout(function () { countdown(mins - 1); }, 1000);

            }

                 //        console.log("minutes",time[0]);
                 //        console.log("seconds",time[1]);

              }

countdown(2);

例如，如果用户结束1分钟，我想得到剩余1分钟的测验所花费的时间我希望有这个。任何人都可以帮助我，渴望得到时间

您可以在下面找到如何开始测验倒计时的示例。

      var seconds = 300;
      function secondPassed() {
          var minutes = Math.round((seconds - 30)/60),
              remainingSeconds = seconds % 60;

          if (remainingSeconds < 10) {
              remainingSeconds = "0" + remainingSeconds;
          }

          document.getElementById('countdown').innerHTML = minutes + ":" + remainingSeconds;
          if (seconds == 0) {
              clearInterval(countdownTimer);
        //your code here 
          } else {
              seconds--;
          }
      }
      var countdownTimer = setInterval('secondPassed()', 1000);

.timer {
    width: 200px;
    font-size: 2.5em;
    text-align: center;
}

<div class="timer">
            <time id="countdown">5:00</time>
</div>

如何获得时间

var time = document.getElementById("countdown").innerText.split(":").map(function(val){ return parseInt(val)});
console.log("minutes",time[0]);
console.log("seconds",time[1]);
