利用setTime()实现动态的时钟效果
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 onLoad="disptime( ) ">
<form name="myform">
<input name="myclock" type="text" value="" size="20">
</form>
<span id="clock"></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
