解决方法
这样的事情应该做的伎俩.我很无聊,决定自己做,而不是Googling.只需将顶部的分钟数和秒数设置为on,则将onload中的调用更改为要更新的元素的ID.

var interval;
var minutes = 1;
var seconds = 5;
window.onload = function() {
countdown('countdown');
}
function countdown(element) {
interval = setInterval(function() {
var el = document.getElementById(element);
if(seconds == 0) {
if(minutes == 0) {
el.innerHTML = "countdown's over!";
clearInterval(interval);
return;
} else {
minutes--;
seconds = 60;
}
}
if(minutes > 0) {
var minute_text = minutes + (minutes > 1 ? ' minutes' : ' minute');
} else {
var minute_text = '';
}
var second_text = seconds > 1 ? 'seconds' : 'second';
el.innerHTML = minute_text + ' ' + seconds + ' ' + second_text + ' remaining';
seconds--;
},1000);
}

<div id='countdown'></div>
