广告JS代码效果大全

2.[鼠标感应]
与前面一个代码不同的是，当鼠标移动到广告图片上是可以感应显示另外设置好的广告大图效果，下面就是实现效果所需代码：

3.[允许关闭]
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.object.style.display = 'none';
}
return;
}
for(var i=0;i<collection.length;i++)
{
var followObj = collection.object;
var followObj_x = (typeof(collection.x)=='string'?eval(collection.x):collection.x);
var followObj_y = (typeof(collection.y)=='string'?eval(collection.y):collection.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 href=http://www.dfeng.net target=_blank><img src=ad/doublead/right.gif width=100 height=554 border=0></a><br><br><img src=ad/doublead/close.gif >');
theFloaters.addItem('followDiv2',0,0,'<a href=http://www.dfeng.net target=_blank><img src=ad/doublead/ad_ad.gif width=100 height=400 border=0 ></a><br><br><img src=ad/doublead/close.gif >');
theFloaters.play();

把上面的代码分别另存为两个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！

4.[浮动对联广告---之左侧代码]

如果您想只有一侧显示的话,下面是实现左侧效果所需代码：

var ad_float_left_src ="图片地址";

}
function leftmove()

setTimeout("leftmove();",50)
}

resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&
(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight;
onresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW || innerHeight!

}

document.write("<div id=myleft style='position:
absolute;width:80;top:300;left:5;visibility: visible;z-index: 1'>"

+"A.closefloat:link,A.refloat:visited {text-
decoration:none;color:#000000;font-size:12px}"
+"A.closefloat:active,A.refloat:hover {text-decoration:underline;color:#0000FF;font-size:12px}"
+"</style>"
+"<table border=0 cellpadding=0 cellspacing=0><tr><td>");

if(document.ns){
if(ad_float_left_type!="swf")
document.write("<a href='" + ad_float_left_url + "' target
= '_blank'><img src='" + ad_float_left_src + "' WIDTH=88
height=31 border=0></a>");
else

myload()}

[ 5.背投广告]

<script language="javascript">
<!--
var sohu=window.open('http://www.sohu.com');
var ads=window.open('about:blank','ads','width=700,height=400');
sohu.focus();
ads.document.open();
ads.document.write ("<html><head><title>ads</title></head><body>This is background ads</body></html>");
ads.document.close();
//-->
</script>

[ 6.收缩广告]

<script language="javascript">
<!--
var bwidth=800;
var bheight=400;
function go() {
bwidth = bwidth - 10;
bheight = bheight - 5;
if(bwidth <= 10)
{ ads.style.display='none';clearTimeout("my"); }
else
{ ads.outerHTML='<span id="ads" style="width:'+bwidth+'px;height:'+bheight+'px;background-color:#0099FF;"></span>';}
var my=setTimeout("go()",50);
}
setTimeout("go()",6000);
//-->
</script>
<body topmargin="0" leftmargin="0">
<div align="center"><span id="ads" style="width:800px;height:400px;background-color:#0099FF"></span></div>
</body>

把上面的代码另存为三个*.JS文件，然后在想实现此效果的页面用

CODE:
<script 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！相应的参数可以根据页面自行调整
