請將以下程式複製至<head>與</head>之間

　 <script language="JavaScript"> var DifferenceHour = -1 var DifferenceMinute = -1 var DifferenceSecond = -1 var Tday = new Date("Janu 1, 2002 0:0:0") var daysms = 24 * 60 * 60 * 1000 var hoursms = 60 * 60 * 1000 var Secondms = 60 * 1000 var microsecond = 1000 function clock() { var time = new Date() var hour = time.getHours() var minute = time.getMinutes() var second = time.getSeconds() var timevalue = ""+((hour > 12) ? hour-12:hour) timevalue +=((minute < 10) ? ":0":":")+minute timevalue +=((second < 10) ? ":0":":")+second timevalue +=((hour >12 ) ? " PM":" AM") var convertHour = DifferenceHour var convertMinute = DifferenceMinute var convertSecond = DifferenceSecond var Diffms = Tday.getTime() - time.getTime() DifferenceHour = Math.floor(Diffms / daysms) Diffms -= DifferenceHour * daysms DifferenceMinute = Math.floor(Diffms / hoursms) Diffms -= DifferenceMinute * hoursms DifferenceSecond = Math.floor(Diffms / Secondms) Diffms -= DifferenceSecond * Secondms var dSecs = Math.floor(Diffms / microsecond) if(convertHour != DifferenceHour) document.formnow.dd.value=DifferenceHour if(convertMinute != DifferenceMinute) document.formnow.hh.value=DifferenceMinute if(convertSecond != DifferenceSecond) document.formnow.mm.value=DifferenceSecond document.formnow.ss.value=dSecs setTimeout("clock()",1000) } </script>

請將以下程式複製至 <body> 與 </body> 之間

請以以下程式放在 <body 與 > 之間

即是...<body (程式放置的位置) >

　 onload="clock();return true"

修改：

將 var Tday = new Date("Janu 1, 2002 0:0:0")

改成您想顯示的日期
