直接把代码复制过去就可以用
<script language="javascript">
function time(){
var Timer=new Date()
var year=Timer.getYear();
var month=Timer.getMonth()+1;
var date_=Timer.getDate();
var day=Timer.getDay()+1;
var hours=Timer.getHours()
var minutes=Timer.getMinutes()
var seconds=Timer.getSeconds()
var noon="AM"
function initArray(){
this.length=initArray.arguments.length
for(var i=0;i<this.length;i++)
this[i+1]=initArray.arguments[i]
}
var d=new initArray("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
if (hours>12){
noon="PM"
hours=hours-12
}
if (hours==0)
hours=12
if (minutes<=9)
minutes="0"+minutes
if (seconds<=9)
seconds="0"+seconds
clock=""+year+"-"+month+"-"+date_+" "+d[day]+" "+hours+":"+minutes+":"+seconds+"";
position.innerHTML=clock;//注意这里的postion是一个标记的id
setTimeout("time()",1000);
}
</script>
<body onLoad="time()">
<span id="position"></span>
</body>
