代码如下
<html> <head> <meta charset="utf-8"> <title>正在运行的时钟</title> <style type="text/css"> /*设置样式：无边框的文本框*/ input, #clock { width: 390; font-size: 30px; font-weight: 900; color: #FFFFFF; background-color: #930; border: 8px double #900; } </style> </head> <body> <form> <input type="text" value="" size="20"> </form> <span></span> <script language="JavaScript"> function disptime() { var time = new Date(); //获得当前时间 var year = time.getFullYear(); //获得年月日 var month = time.getMonth(); //获得年月日 var date = time.getDate(); //获得年月日 var hour = time.getHours(); //获得小时、分钟、秒 var minute = time.getMinutes(); var second = time.getSeconds(); if (minute < 10) //如果分钟只有1位，补0显示 minute = "0" + minute; if (second < 10) //如果秒数只有1位，补0显示 second = "0" + second; /*设置文本框的内容为当前时间*/ document.getElementById('clock').innerHTML = year + "年" + month + "月" + date + "日" + hour + ":" + minute + ":" + second document.myform.myclock.value = year + "年" + month + "月" + date + "日" + hour + ":" + minute + ":" + second /*设置定时器每隔1秒（1000毫秒），调用函数disptime()执行，刷新时钟显示*/ var myTime = setTimeout("disptime()", 1000); } </script> </body> </html>
效果如图
