飘落的多图片

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<STYLE>
#Layer0 {
	Z-INDEX: 10; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
#Layer1 {
	Z-INDEX: 20; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
#Layer2 {
	Z-INDEX: 30; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
#Layer3 {
	Z-INDEX: 40; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
#Layer4 {
	Z-INDEX: 50; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
#Layer5 {
	Z-INDEX: 60; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
#Layer6 {
	Z-INDEX: 70; LEFT: -100px; WIDTH: 60px; POSITION: absolute; TOP: -100px; HEIGHT: 60px
}
BODY {
	FONT-SIZE: 9pt; WORD-SPACING: normal; LINE-HEIGHT: 13pt
}
P {
	FONT-SIZE: 9pt; WORD-SPACING: normal; LINE-HEIGHT: 13pt
}
TD {
	FONT-SIZE: 9pt; WORD-SPACING: normal; LINE-HEIGHT: 13pt
}
</STYLE>

<SCRIPT language=JavaScript>
xfirst = new Array(80,150,220,310,400,590,680);	//初始x位置
yfirst = new Array(0,180,70,10,50,30,140); 	//初始y位置

ycoor = new Array(0,180,70,10,50,30,140);
xdirec= new Array(1,-1,1,-1,1,-1); //初始方向 -1 为左 and 1 为右
var ns = navigator.appName == "Netscape";
function doplay()
{
    var x,y,i,j,w,h;
	w = window.screen.width - 100;
//	w = document.body.clientWidth - 100;
	h = window.screen.height - 100;
//	h = document.body.clientHeight - 50;
    for(j=0;j<7;j++){
    	i=Math.random();  				 //随机改变运动方向
    	if (i > 0.95) xdirec[j] = 0 - xdirec[j];  
    	x=Math.floor(10*Math.random());
    	y=Math.floor(5*Math.random());	//x和y方向上的随机增量
    	if ( xdirec[j] == 1 ) xcoor[j] = xcoor[j] + x;
    	else xcoor[j] = xcoor[j] - x;
    	ycoor[j] = ycoor[j] + y;  		//x越界则变向,y越界则返回
    	if ( xcoor[j] >= w ) {xcoor[j]=w;xdirec[j]=-1;}
    	if ( xcoor[j] <= 0 ) {xcoor[j]=0;xdirec[j]=1;}
    	if ( ycoor[j] >= h ) {xcoor[j]=xfirst[j];ycoor[j]=yfirst[j];}
        if (!ns){ eval('document.all'+'["Layer'+j+'"]'+'.style.left='+xcoor[j]);
		eval('document.all'+'["Layer'+j+'"]'+'.style.top='+ycoor[j]);}
        else {  eval('document.layers'+'["Layer'+j+'"]'+'.left='+xcoor[j]);
		eval('document.layers'+'["Layer'+j+'"]'+'.top='+ycoor[j]);}
	}
    setTimeout('doplay()',100);  
}
doplay()
</SCRIPT>
<DIV id=Layer0><IMG height=14 src="hua1.gif" width=14> </DIV>
<DIV id=Layer1><IMG height=25 src="hua.gif" width=25> </DIV>
<DIV id=Layer2><IMG height=25 src="hua.gif" width=25> </DIV>
<DIV id=Layer3><IMG height=14 src="hua2.gif" width=14> </DIV>
<DIV id=Layer4><IMG height=14 src="hua1.gif" width=14> </DIV>
<DIV id=Layer5><IMG height=14 src="hua2.gif" width=14> </DIV>
<DIV id=Layer6><IMG height=25 src="hua.gif" width=25> </DIV>

第二步：把<body>中的内容改为：
<body onload=doplay()>
