复制代码 代码如下:

<script language ="javascript" type ="text/javascript">

var second=0;

var minute=0;

var hour=0;

window .setInterval ("OnlineStayTimes();",1000);

function OnlineStayTimes()

{

second ++;

if(second ==60){second =0;minute +=1;}

if(minute ==60){minute =0;hour +=1;}

var tm=hour+"小时"+minute +"分钟"+second +"秒"

document.getElementById ("time").innerHTML=tm;

}

</script>

上面代码中document.getElementById ("time").innerHTML=tm;中“time”是label的id，这样即可实现显示在线时间的功能！
