Positive and Countdown Timer

標題：正倒數計時器
JavaScript (index.html)：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

<span id="loveboxy"></span> <script type="text/javascript"> var TimerBoxy = function(e) { this.id = e.id; this.target = new Date(e.target); }; TimerBoxy.prototype.show = function() { var s = Math.abs(parseInt( (new Date().getTime() - this.target.getTime() )/1000,10)); var m = s/60; var h = m/60; var D = h/24; document.getElementById(this.id).innerHTML = parseInt(D,10) + "日" + parseInt(h%24,10) + "時" + parseInt(m%60,10) + "分" + parseInt(s%60,10) + "秒"; }; TimerBoxy.prototype.start = function() { if(!this.timer) { var that = this; this.show(); this.timer = window.setInterval(function() { that.show(); }, 1000); } }; TimerBoxy.prototype.stop = function() { if(this.timer) { window.clearInterval(this.timer); this.timer = null; } }; loveboxy = new TimerBoxy({ id : "loveboxy", target : "2011/11/11 11:11:11" }); loveboxy.start(); </script>

使用範例：
4892日1時55分32秒

說明：
當目標時間小於當日時間則為正數計時，反之則為倒數計時。
