现在很多网站广告做的如火如荼，现在我就来介绍一下常见的对联浮动广告效果的代码使用方法，本文介绍的这种效果，在1024*768分辨率下正常显示，在800*600的分辨率下可以自动隐藏，以免遮住页面影响访问者浏览内容，而且与前面两个代码不同的是，广告图下方增加了一个图片按纽，允许访客点击关闭广告图片，下面文本框中就是实现效果所需代码：
var delta=0.015;
var collection;
var closeB=false;
function floaters() {
this.items = [];
this.addItem = function(id,x,y,content)
{
document.write('<DIV id='+id+' style="Z-INDEX: 10; POSITION: absolute; width:80px; height:60px;left:'+(typeof(x)=='string'?eval(x):x)+';top:'+(typeof(y)=='string'?eval(y):y)+'">'+content+'</DIV>');
var newItem = {};
newItem.object = document.getElementById(id);
newItem.x = x;
newItem.y = y;
this.items[this.items.length] = newItem;
}
this.play = function()
{
collection = this.items
setInterval('play()',30);
}
}
function play()
{
if(screen.width<=800 || closeB)
{
for(var i=0;i<collection.length;i++)
{
collection[i].object.style.display = 'none';
}
return;
}
for(var i=0;i<collection.length;i++)
{
var followObj = collection[i].object;
var followObj_x = (typeof(collection[i].x)=='string'?eval(collection[i].x):collection[i].x);
var followObj_y = (typeof(collection[i].y)=='string'?eval(collection[i].y):collection[i].y);
if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {
var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;
dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));
followObj.style.left=followObj.offsetLeft+dx;
}
if(followObj.offsetTop!=(document.body.scrollTop+followObj_y)) {
var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta;
dy=(dy>0?1:-1)*Math.ceil(Math.abs(dy));
followObj.style.top=followObj.offsetTop+dy;
}
followObj.style.display = '';
}
}
function closeBanner()
{
closeB=true;
return;
}
var theFloaters = new floaters();
//
theFloaters.addItem('followDiv1','document.body.clientWidth-100',0,'<a onClick="closeBanner();" href=http://www.webjx.com target=_blank><img src=/img2/js050121_1.gif width=100 height=400 border=0></a><br><img src="/img2/js050121_close.gif" onClick="closeBanner();">');
theFloaters.addItem('followDiv2',0,0,'<a onClick="closeBanner();" href=http://www.webjx.com target=_blank><img src=/img2/js050121_2.gif width=100 height=400 border=0 ></a><br><img src="/img2/js050121_close.gif" onClick="closeBanner();">');
theFloaters.play();
把上面的代码另存为一个JS文件，然后在想实现此效果的页面用<script type="text/javascript" language="javascript1.2" src="*.js"></SCRIPT>调用即可，*代表你另存的文件名！注意修改广告图片地址和连接地址！
网页两侧浮动广告代码
关键词： 网页两侧浮动广告代码
在BODY内加入以下代码:
***********************************************
"< DIV id=floater1 style="Z-INDEX: 100; LEFT: 10px; VISIBILITY: visible; WIDTH: 100px; POSITION: absolute; TOP: 160px; height: 100px;" >
左边的東西,可以是图片,表格
< /DIV >
< DIV id=floater style="Z-INDEX: 100; RIGHT: 10px; VISIBILITY: visible; WIDTH: 100px; POSITION: absolute; TOP: 160px; left: 890px;" >
右边的東西,可以是图片,表格
< /DIV >"
***********************************************
menus.js的代码如下:
***********************************************
self.onError = null;
currentX = currentY = 0;
whichIt = null;
lastScrollX = 0; lastScrollY = 0;
NS = (document.layers) ? 1 : 0;
IE = (document.all) ? 1: 0;
function heartBeat(objectid) {
if(IE) { diffY = document.body.scrollTop; diffX = document.body.scrollLeft; }
if(NS) { diffY = self.pageYOffset; diffX = self.pageXOffset; }
if(diffY != lastScrollY) {
percent = .1 * (diffY - lastScrollY);
if(percent > 0) percent = Math.ceil(percent);
else percent = Math.floor(percent);
if(IE) {
objectid = objectid.split(";");
for (i = 0; i < objectid.length; i++) eval("document.all."+objectid[i]).style.pixelTop += percent;
}
if(NS) {
objectid = objectid.split(";");
for (i = 0; i < objectid.length; i++) eval("document."+objectid[i]).top += percent;
}
lastScrollY = lastScrollY + percent;
}
if(diffX != lastScrollX) {
percent = .1 * (diffX - lastScrollX);
if(percent > 0) percent = Math.ceil(percent);
else percent = Math.floor(percent);
if(IE) {
objectid = objectid.split(";");
for (i = 0; i < objectid.length; i++) eval("document.all."+objectid[i]).style.pixelLeft += percent;
}
if(NS) {
objectid = objectid.split(";");
for (i = 0; i < objectid.length; i++) eval("document."+objectid[i]).left += percent;
}
lastScrollX = lastScrollX + percent;
}
}
if(NS || IE) action = window.setInterval("heartBeat('floater;floater1')", 2);
***********************************************
OK,成功就这么简单!DIV内的文字可以换成图片和表格,ID不改就行了...
另外,记得以上代码为了不干扰本文章的显示,在"<>"中多加了空格,拷贝到文档以后记得修改.

除了上述方法之外,还另从其他网站搜集到另一种实现方法,方法如下:
在显示页面中加入:
< SCRIPT language="JavaScript" src="js/flr.js" >< /SCRIPT >
< SCRIPT language="JavaScript" src="js/fll.js" >< /SCRIPT >
---------------------------flr.js------------------------------------

当然,这种方法要比较麻烦一点,要做三个文件处理,喜欢用哪个,你自己挑吧!吼吼!
