代码如下： <!--脚本说明：第一步:把如下代码加入<body>区域中:--> <script language="JavaScript"> function showMilitaryTime() { if (document.form.showMilitary[0].checked) { return true; } return false; } function showTheHours(theHour) { if (showMilitaryTime() || (theHour > 0 && theHour < 13)) { if (theHour == "0") theHour = 12; return (theHour); } if (theHour == 0) { return (12); } return (theHour-12); } function showZeroFilled(inValue) { if (inValue > 9) { return "" + inValue; } return "0" + inValue; } function showAmPm() { if (showMilitaryTime()) { return (""); } if (now.getHours() < 12) { return (" am"); } return (" pm"); } function showTheTime() { now = new Date document.form.showTime.value = showTheHours(now.getHours()) + ":" + showZeroFilled(now.getMinutes()) + ":" + showZeroFilled(now.getSeconds()) + showAmPm() setTimeout("showTheTime()",1000) } </script> <FORM name=form><INPUT name=showTime size=11> <P><INPUT CHECKED name=showMilitary type=radio>Military Time<BR><INPUT name=showMilitary type=radio Unchecked> 12 Hour Time </FORM> <!--第二步:把<body>区域中的内容改为:--> <body bgcolor="#fef4d9" onload=showTheTime()>
