要完成此效果需要三个步骤
第一步：把如下代码加入到<head>区域中
<script language=javaScript>
<!--//
function clockon() {
thistime= new Date()
var hours=thistime.getHours()
var minutes=thistime.getMinutes()
var seconds=thistime.getSeconds()
if (eval(hours) <10) {hours="0"+hours}
if (eval(minutes) < 10) {minutes="0"+minutes}
if (seconds < 10) {seconds="0"+seconds}
thistime = hours+":"+minutes+":"+seconds
if(document.all) {
bgclocknoshade.innerHTML=thistime
bgclockshade.innerHTML=thistime
}
if(document.layers) {
document.bgclockshade.document.write('<div id="bgclockshade"
style="position:absolute;visibility:visible;font-family:Verdana;color:FFAAAAA;font-size:120px;top:10px;left:152px">'+thistime+'</div>')
document.bgclocknoshade.document.write('<div id="bgclocknoshade"
style="position:absolute;visibility:visible;font-family:Verdana;color:DDDDDD;font-size:120px;top:10px;left:150px">'+thistime+'</div>')
document.close()
}
var timer=setTimeout("clockon()",200)
}
//-->
</script>
第二步：把如下代码加入到<body>区域中
<div id="bgclockshade" style="position:absolute;visibility:visible;font-family:Arial;color:FF8888;font-size:120px;top:177px;left:127px"></div>
<div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:Arial;color:DDDDDD;font-size:120px;top:195px;left:150px"></div>
<div id="mainbody" style="position:absolute;
visibility:visible"></div>
第三步：把“onLoad="clockon()"”加在<body>标记里
例如：<body onLoad="clockon()">
