An example of javascript background clock is presented. Share to everybody for everybody reference. The details are as follows:

Here is the complete code for this effect. [Best to start with 1 blank page]


<html>
<head>
<TITLE> Setting the clock </TITLE> 
<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>
<link rel="stylesheet" href="../style.css"></head>
<body onLoad="clockon()">
<div id="bgclockshade" style="position:absolute;visibility:visible;font-family:Arial;color:FF8888;font-size:120px;top:102px;left:152px"></div>
<div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:Arial;color:DDDDDD;font-size:120px;top:100px;left:150px"></div>
<div id="mainbody" style="position:absolute; visibility:visible">
</div>
</body>
</html>

Note: You need to modify the TOP,LEFT parameter to determine the position of the clock display. TOP represents the pixel value of the layer at the top of the display, and LEFT represents the pixel value at the left.
