本文实例讲述了javascript实时显示当天日期的方法。分享给大家供大家参考。具体实现方法如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>js显示时间</title>
</head>
<body>
<div id="divBottom"></div>
<script type="text/javascript">
//获取当天日期
function date()
{
var date=new Date();
var year=date.getFullYear();
var month=date.getMonth()+1;
var day=date.getDate();
var hour="00"+date.getHours();
hour=hour.substr(hour.length-2);
var minute="00"+date.getMinutes();
minute=minute.substr(minute.length-2);
var second="00"+date.getSeconds();
second=second.substr(second.length-2);
var week=date.getDay();
switch(week)
{
case 1:week="星期一 ";break;
case 2:week="星期二 ";break;
case 3:week="星期三 ";break;
case 4:week="星期四 ";break;
case 5:week="星期五 ";break;
case 6:week="星期六 ";break;
case 0:week="星期日 ";break;
default:week="";break;
}
document.getElementById("divBottom").innerHTML=year+"年"+month+"月"+day+"日"+" "+hour+":"+minute+":"+second+" "+week;
}
setInterval("date()",1000);
</script>
</body>
</html>
运行效果如下图所示：
