这是你想要的，我刚才用过的 -

Here is what you want, I used a while ago - https://jsfiddle.net/v5uc9wfx/3/

       function CountDown(duration, display) {
        if (!isNaN(duration)) {
            var timer = duration, minutes, seconds;

          var interVal=  setInterval(function () {
                minutes = parseInt(timer / 60, 10);
                seconds = parseInt(timer % 60, 10);

                minutes = minutes < 10 ? "0" + minutes : minutes;
                seconds = seconds < 10 ? "0" + seconds : seconds;

                $(display).html("<b>" + minutes + "m : " + seconds + "s" + "</b>");
                if (--timer < 0) {
                    timer = duration;
                   SubmitFunction();
                   $('#display').empty();
                   clearInterval(interVal)
                }
                },1000);
        }
    }

此处 -

CountDown(duration, display) 

持续时间以秒为单位传递，即300秒= 5分钟。 display是你想要显示的另一个参数。

Duration is passed in seconds, i.e. 300 second= 5 Minutes. display is another parameter you want to display where.

您可能还需要清除间隔 -

You might need to clear interval as well-

  clearInterval(interVal)

使用form- https://jsfiddle.net/v5uc9wfx/4/
