下面是雪花飘落的js代码

拷进去就好了，或者调用！！！！

不停变换的背景颜色[共1步]

====1、将以下代码加入HTML的<body></body>之间：

<!-- Hide from JavaScript-Impaired Browsers

var pos = 10

function initArray() {

this.length = initArray.arguments.length

for (var i = 0i <this.lengthi++) {

this[i] = initArray.arguments[i]

}

var col=new initArray("4b","5b","8b","8b")

col[0] = "yellow"

col[1] = "coral"

col[2] = "orange"

col[3] = "red"

col[4] = "greenyellow"

col[5] = "lime"

col[6] = "turquoise"

col[7] = "coral"

col[8] = "blueviolet"

col[9] = "violet"

function chgCol() {

pos++

if (pos<0||pos>9) {

pos = 0

}

document.bgColor = col[pos]

setTimeout("chgCol()",5000)

/* Change above set to every 10 seconds (1000 = 1 sec) If

you wish to speed it up, lower the number. To slow it

down, raise the number. */

}

var yourwords = "不断变化背景色彩"var buffer1=" "var buffer2=" "var message1=buffer1+yourwords+buffer2var dir = "left"var speed =150function pingpong(){if (dir == "left") { message2=message1.substring(2,message1.length)+" "window.status=message2setTimeout("pingpong()",speed)message1=message2if (message1.substring(0,1) == "*") dir="right"}else { message2=" "+message1.substring(0,message1.length-2)window.status=message2setTimeout("pingpong()",speed)message1=message2if (message1.substring(message1.length-1,message1.length) == "*") dir="left"}}// --></script>

检测浏览器类型并调用不同的背景音乐[修改MIDI文件名][共1步]

====1、将以下代码加入HTML的<body></body>之间：

<!-- Begin

var MSIE=navigator.userAgent.indexOf("MSIE")

var NETS=navigator.userAgent.indexOf("Netscape")

var OPER=navigator.userAgent.indexOf("Opera")

if((MSIE>-1) || (OPER>-1)) {

document.write("<BGSOUND SRC=sound.mid LOOP=INFINITE>")

} else {

document.write("<EMBED SRC=sound2.mid AUTOSTART=TRUE ")

document.write("HIDDEN=true VOLUME=100 LOOP=TRUE>")

}

// End -->

</SCRIPT>

滚动背景[特别推荐][共1步][IE专用]<先在页面中设置好背景图片然后再进行下一步>

====1、将以下代码加入HEML的<body></body>之间：

dim c,numgc

c=-100000

numgc=document.body.sourceIndex

sub SF

c=c+1

Document.all(numgc).style.BackgroundPosition= "0 " &c

id=SetTimeOut("SF",16,"VBScript")

end sub

</script>

永远居中的背景图片[推荐][共1步][修改图片名称]

====1、将以下代码加入HEML的<body></body>之间：

<!--

BODY {background-image: URL(图片名称.gif)

background-position: center

background-repeat: no-repeat

background-attachment: fixed}

-->

</STYLE>

随机显示的背景图片[想别人每次看你页面时背景都不一样吗？][共1步]

====1、将以下代码加入HTML的<head></head>之间：

bg = new Array(2)//设定图片数量，如果图片数为3，这个参数就设为2，依次类推

bg[0] = 'bg1.gif' //显示的图片路径，可用http://

bg[1] = 'bg2.gif'

bg[2] = 'bg3.gif'

index = Math.floor(Math.random() * bg.length)

document.write("<BODY BACKGROUND="+bg[index]+">")

</script>

跟随屏幕移动的图像[推荐]修改图片名称和文字即可][共2步]

====1、将以下代码加入到HEML的<head></head>之间：

#floater {

position: absolute

left: 500

top: 146

width: 125

visibility: visible

z-index: 10

}</style>

====2、将以下代码加入到HEML的<body></body>之间
