陪LP大人加班没事做，也来玩一个。

<input id=output value="00:00:00.000"/>
<input type="button" value=" Start " onclick="begin()" id=start />
<input type="button" value=" Reset " onclick="reset()">
<script>
var countedTime,startTime,timer,interval=10;
function begin(){
startTime = new Date();
start.value=" Pause ";
start.onclick= pause;
timer = setInterval("count()",interval)
}
function pause(){
start.value=" Resume";
start.onclick= resume;
countedTime = new Date() - startTime;
clearInterval(timer);
}
function resume(){
startTime = new Date(new Date()-countedTime)
start.value=" Pause ";
start.onclick= pause;
timer = setInterval("count()",interval)
}
function count(){
var mSecond = (new Date()) - startTime;
var hour = Math.floor(mSecond/3600000);
mSecond -= hour*3600000;
hour = (hour<10?"0":"")+hour;
var minute = Math.floor(mSecond/60000);
mSecond -= minute*60000;
minute = (minute<10?"0":"")+minute ;
var second = Math.floor(mSecond/1000);
mSecond -= second*1000;
second = (second<10?"0":"")+second ;
mSecond = (mSecond<100?mSecond<10?"00":"0":"")+mSecond ;
var st = hour+":"+minute+":"+second+"."+mSecond;
output.value = st;
}
function reset(){
startTime = null;
clearInterval(timer);
output.value = output.defaultValue;
start.value=" Start ";
start.onclick=begin;
}
</script>

可以
只是很麻烦要定义好多位置如WINDOW2K系统带的表一样
