asp.net中将js的返回值赋给asp.net控件的小例子

    <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>
