在网页上设计飘动广告 - 网页制作

把下面的代码加入<head>...</head>之间：
var brOK=false;
var mie=false;
var aver=parseInt(navigator.appVersion.substring(0,1));
var aname=navigator.appName;
  //check browser
function checkbrOK()
{
if(aname.indexOf("Internet Explorer")!=-1)
{
  if(aver>=4)
   brOK=navigator.javaEnabled();
  mie=true;
}
if(aname.indexOf("Netscape")!=-1)
{
  if(aver>=4)
   brOK=navigator.javaEnabled();
}
}

var vmin=5;
var vmax=2;
var vr=2;
var timer1;
function Chip(chipname,width,height)
{
   this.named=chipname;
   this.vx=vmin+vmax*Math.random();
   this.vy=vmin+vmax*Math.random();
   this.w=width;
   this.h=height;
   this.xx=0;
   this.yy=0;
   this.timer1=null;
}
function movechip(chipname)
{
   if(brOK)
   {
  eval("chip="+chipname);
  if(!mie)
  {
   pageX=window.pageXOffset;
   pageW=window.innerWidth;
   pageY=window.pageYOffset;
   pageH=window.innerHeight;
  }
  else
  {
   pageX=window.document.body.scrollLeft;
   pageW=window.document.body.offsetWidth-8;
   pageY=window.document.body.scrollTop;
   pageH=window.document.body.offsetHeight;
  }
  chip.xx=chip.xx+chip.vx;
  chip.yy=chip.yy+chip.vy;
  chip.vx+=vr*(Math.random()-0.5);
  chip.vy+=vr*(Math.random()-0.5);
  if(chip.vx>(vmax+vmin))  chip.vx=(vmax+vmin)*2-chip.vx;
  if(chip.vx<(-vmax-vmin)) chip.vx=(-vmax-vmin)*2-chip.vx;
  if(chip.vy>(vmax+vmin))  chip.vy=(vmax+vmin)*2-chip.vy;
  if(chip.vy<(-vmax-vmin)) chip.vy=(-vmax-vmin)*2-chip.vy;
  if(chip.xx<=pageX)
  {
   chip.xx=pageX;
   chip.vx=vmin+vmax*Math.random();
  }
  if(chip.xx>=pageX+pageW-chip.w)
  {
   chip.xx=pageX+pageW-chip.w;
   chip.vx=-vmin-vmax*Math.random();
  }
  if(chip.yy<=pageY)
  {
   chip.yy=pageY;
   chip.vy=vmin+vmax*Math.random();
  }
  if(chip.yy>=pageY+pageH-chip.h)
  {
   chip.yy=pageY+pageH-chip.h;
   chip.vy=-vmin-vmax*Math.random();
  }
  if(!mie)
  {
   eval("document."+chip.named+".top ="+chip.yy);
   eval("document."+chip.named+".left="+chip.xx);
  }
  else
  {
   eval("document.all."+chip.named+".style.pixelLeft="+chip.xx);
   eval("document.all."+chip.named+".style.pixelTop ="+chip.yy);
  }
  chip.timer1=setTimeout("movechip(""+chip.named+"")",100);
}
}
function stopme(chipname)
{
if(brOK)
{//alert(chipname)
  eval("chip="+chipname);
  if(chip.timer1!=null)
  {
   clearTimeout(chip.timer1);
  }
}
}

var floater;
function floater()
{
checkbrOK();
    floater=new Chip("floater",0,0);
    if(brOK)
    {
  movechip("floater");
}
}

把下面的代码加入<body>...</body>之间：
<div id=floater style="HEIGHT: 0px; POSITION: absolute; WIDTH: 0px; left: 680px; top: 150px; z-index:100" >

</div>
这里你可以改成自己要的图片路径．
