javascript 显示当前系统时间代码

1.在<head></head>中加入下列代码复制代码代码如下: <script language=JavaScript> var timerID = null; var timerRunning = false; function stopclock (){ if(timerRunning) clearTimeout(timerID); timerRunning = false;} function startclock () { stopclock(); showtime();} function showtime () { var now = new Date(); var hours = now.getHours(); var minutes = now.getMinutes(); var seconds = now.getSeconds() var timeValue = "" +((hours >= 12) ? "下午 " : "上午 " ) timeValue += ((hours >12) ? hours -12 :hours) timeValue += ((minutes < 10) ? ":0" : ":") + minutes timeValue += ((seconds < 10) ? ":0" : ":") + seconds document.clock.thetime.value = timeValue; timerID = setTimeout("showtime()",1000); timerRunning = true;} </SCRIPT> 2.在<body>中加入下列代码 onload=startclock() 3.在显示时间的位置插入下列代码,建议使用表格定位 [code] <form name=clock > <input name=thetime style="font-size: 9pt;color:#000000;border:0" size=12> </form> //只获得当前系统日期的函数 <script language="JavaScript" type="text/javascript"> document.write(new Date().getYear()+"-"+(new Date().getMonth()+1)+"-"+new Date().getDate()); </script>http://www.jb51.net/article/12786.htm
