脚本说明:
第一步：把如下代码加入<body>区域中
<script language="JavaScript">

<!--
var timerID = null
var timerRunning = false
function stopclock(){
    if(timerRunning)
        clearTimeout(timerID)
    timerRunning = false
}

function startclock(){
    stopclock()
    showtime()
}

function showtime(){
    var now = new Date()
    var hours = now.getHours()
    var minutes = now.getMinutes()
    var seconds = now.getSeconds()
    var timeValue = "" + ((hours > 12) ? hours - 12 : hours)
    timeValue  += ((minutes < 10) ? ":0" : ":") + minutes
    timeValue  += ((seconds < 10) ? ":0" : ":") + seconds
    if (hours>=6 && hours<=12)
       {timeValue  += ("上午")}
    if(hours>12 && hours<=18) 
       {timeValue += ("下午")}
    if(hours>18 && hours <=24)
       {timeValue +=("晚上")}
    if(hours<6) 
       {timeValue += ("深夜")}
    document.clock.face.value = timeValue 
    timerID = setTimeout("showtime()",1000)
    timerRunning = true
}


//-->
</script>
 <form method="POST" name="clock">
                    <p> 
                      <input type="text" name="face" size="11" style="font-size: 9pt">
                    </p>
                  </form>


第二步：把<body>区域改为
<body bgcolor="#fef4d9" onLoad="startclock();">
</textarea>
<SCRIPT LANGUAGE="JavaScript">

<!-- hide

function goHist(a) 

{

   history.go(a);

}

//-->

</script>

<FORM METHOD="post">
<INPUT TYPE="button" VALUE="返回" onClick="goHist(-1)" style="background-color: #8000FF; color: rgb(255,255,255)">
</form>
</center>
<br>
<br>
</body>
