?<script type="text/javascript">????? window.onload= function w(){????????? var time=new Date();????????? var year=time.getFullYear();????????? var month=time.getMonth()+1;????????? var day=time.getDate();????????? var week=time.getDay()????????? var weekday=new Array();??????????? weekday[0]="星期日";??????????? weekday[1]="星期一";??????????? weekday[2]="星期二";??????????? weekday[3]="星期三";??????????? weekday[4]="星期四";??????????? weekday[5]="星期五";??????????? weekday[6]="星期六";????????? var h=time.getHours();????????? var m=time.getMinutes();????????? var s=time.getSeconds();??????? document.getElementById("first1").innerHTML=year+"年"+month+"月"+day+"日"+weekday[week]+h+":"+m+":"+s;?????????? setTimeout('w()',500)??????? }??????? ???????? </script>
