本文实例讲述了JavaScript让网页出现渐隐渐显背景颜色的方法。分享给大家供大家参考。具体如下：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>javascript渐隐渐显的背景颜色</title>
<style fprolloverstyle>A:hover {color: #00FFFF}
</style>
</head>
<body onLoad="fadeIn(15)">
<script language="JavaScript">
var Color= new Array("ff","ee","dd","cc","bb","aa","99","88","77","66","55","44","33","22","11","00");
function fadeIn(n) {
if (n >= 1) {
document.bgColor="#" +"00"+ Color[n] +"00"; 
n -= 1;
setTimeout("fadeIn("+n+")", 100);
}
else{setTimeout('fadeOut(1)', 100);}
}
function fadeOut(n) {
if (n <=(Color.length-1)) {
document.bgColor="#" +"00"+ Color[n] +"00";
n += 1;
setTimeout("fadeOut("+n+")", 100)
}
else{setTimeout("fadeIn("+(Color.length-1)+")", 100);}
}
</script>
