特效Tag：电子钟添加

JavaScript跳动的时间电子钟，无不刷新页面实现的液晶电子钟，个人感觉还行啊！

脚本说明：
第一步:如下代码加入<head>中：
<script language="JavaScript">
<!-- Hide this script from old browsers --

</script>
第二步：如下代码加入<body>中：
<FORM NAME='clock' ACTION=''>
<TABLE BORDER=2><TR><TD>
<FONT SIZE=-2>
<INPUT TYPE='text' NAME='display' SIZE=8
 onFocus='wClock.toggle()'
 onMouseOver='self.status="Click here to turn on/off clock"; return true'>
</FONT>
</TD></TR></TABLE>
</FORM>
<FORM NAME='imastudios'>
<INPUT TYPE='radio' NAME='buttons'>
 Tick
<INPUT TYPE='radio' NAME='buttons'>
Tock
<INPUT TYPE='radio' NAME='buttons'>
Tick
<INPUT TYPE='radio' NAME='buttons'>
Tock
<INPUT TYPE='radio' NAME='buttons'>
Tick
</FORM>
第三步：<body>中内容改为：
<body bgcolor="#fef4d9" onLoad='wClock = new clock ("wClock", document.clock.display); wButtons = new buttons ("wButtons", document.imastudios.buttons, 500, 1,-1); wButtons.stop(); wClock.sync ("wButtons", 1)'onUnload='wClock.stop(); wButtons.stop()' bgcolor="#FFFFFF">
