<title>当前系统时间</title>
<link rel="stylesheet" href="style.css" />
<script language="javascript" type="text/javascript">
window.onload = function(){
showTime();
}
function checkTime(i){ //补位处理
if(i<10){
i="0"+i;
}
return i;
}
function showTime(){
var now=new Date();
var year=now.getFullYear() ;
var month=now.getMonth()+1 ;
var Date=now.getDate();
var day= now.getDate() ;
var h= now.getHours() ;
var m= now.getMinutes() ;
var s= now.getSeconds() ;
m=checkTime(m)
s=checkTime(s)
var weekday=new Array(7)
weekday[0]="星期日"

document.getElementById("show").innerHTML=""+year+"年"+month+"月"+day+"日 "+ weekday[d] +h+":"+m+":"+s;

}
</script>
