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！
