作为正常的javascript，它工作正常。
<script>var end = new Date('02/19/2012 10:1 AM'); var _second = 1000; var _minute = _second * 60; var _hour = _minute * 60; var _day = _hour * 24; var timer; function showRemaining() { var now = new Date(); var distance = end - now; if (distance < 0) { clearInterval(timer); document.getElementById('countdown').innerHTML = 'EXPIRED!'; return; } var days = Math.floor(distance / _day); var hours = Math.floor((distance % _day) / _hour); var minutes = Math.floor((distance % _hour) / _minute); var seconds = Math.floor((distance % _minute) / _second); document.getElementById('countdown').innerHTML = days + 'days '; document.getElementById('countdown').innerHTML += hours + 'hrs '; document.getElementById('countdown').innerHTML += minutes + 'mins '; document.getElementById('countdown').innerHTML += seconds + 'secs'; } timer = setInterval(showRemaining, 1000);</script><div id="countdown"></div>您的输出显示如下：-
1days 9hrs 3mins 22secs
更新
使用功能：
<script> CountDownTimer('02/19/2012 10:1 AM', 'countdown'); CountDownTimer('02/20/2012 10:1 AM', 'newcountdown'); function CountDownTimer(dt, id) { var end = new Date(dt); var _second = 1000; var _minute = _second * 60; var _hour = _minute * 60; var _day = _hour * 24; var timer; function showRemaining() { var now = new Date(); var distance = end - now; if (distance < 0) { clearInterval(timer); document.getElementById(id).innerHTML = 'EXPIRED!'; return; } var days = Math.floor(distance / _day); var hours = Math.floor((distance % _day) / _hour); var minutes = Math.floor((distance % _hour) / _minute); var seconds = Math.floor((distance % _minute) / _second); document.getElementById(id).innerHTML = days + 'days '; document.getElementById(id).innerHTML += hours + 'hrs '; document.getElementById(id).innerHTML += minutes + 'mins '; document.getElementById(id).innerHTML += seconds + 'secs'; } timer = setInterval(showRemaining, 1000); }</script><div id="countdown"></div><div id="newcountdown"></div>输出将如下所示：-
