學習了利用JS在html裡面顯示當前時間
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Html+js獲取當前時間</title>
<style type="text/css">
#Main
{
margin-top: 40px;
margin-left: 50px;
height: 100px;
font-size: 30px;
}
</style>
<script type="text/javascript">
window.onload=function()
{
window.requestAnimationFrame(getDate)
}
function getDate()
{
window.setTimeout(function(){
window.requestAnimationFrame(getDate)
},1000/2)
var d=new Date();
var year=d.getFullYear() //獲取年
var month=d.getMonth()+1; //獲取月，從 Date 物件返回月份 (0 ~ 11)，故在此處+1
var day=d.getDay() //獲取日
var days=d.getDate() //獲取日期
var hour=d.getHours() //獲取小時
var minute=d.getMinutes() //獲取分鐘
var second=d.getSeconds() //獲取秒
if(month<10) month="0"+month
if(days<10) days="0"+days
if(hour<10) hour="0"+hour
if(minute<10) minute="0"+minute
if(second<10) second="0"+second
var week=new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六")
var Tools=document.getElementById("Main")
var da=year+" 年 "+month+" 月 "+days+" 日 "+week[day]+" "+hour+" : "+minute+" :"+second
Tools.innerHTML=da
}
</script>
</head>
<body>
<div id="Main"></div>
