js 技巧 （十）广告JS代码效果大全 【3】
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+' >'+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";
var ad_float_left_url ="地址";
var ad_float_left_type = "";
document.ns = navigator.appName == "Microsoft Internet Explorer"
var imgheight_close
var imgleft
window.screen.width>800 ? imgheight_close=120:imgheight_close=120
window.screen.width>800 ? imgleft=8:imgleft=122
function myload()
{
myleft.style.top=document.body.scrollTop+document.body.offsetHeigh
t-imgheight_close;
myleft.style.left=imgleft;
leftmove();
}
function leftmove()
{
myleft.style.top=document.body.scrollTop+document.body.offsetHeigh
t-imgheight_close;
myleft.style.left=imgleft;
setTimeout("leftmove();",50)
}
function MM_reloadPage(init) { //reloads the window if Nav4
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.MM_pgH) location.reload();
}
MM_reloadPage(true)
function close_float_left(){
myleft.style.visibility='hidden';
}
document.write("<div id=myleft style='position:
absolute;width:80;top:300;left:5;visibility: visible;z-index: 1'>"
+"<style>"
+"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
document.write("<EMBED src='" + ad_float_left_src + "'
quality=high WIDTH=80 HEIGHT=80 TYPE='application/x-shockwave-
flash' id=changhongout ></EMBED>");
document.write("</td></tr><tr><td width=80 height=20
align=right><a href='javascript:close_float_left( target=_blank);void(0);'
class="closefloat"><b><font color=#ff0000>关闭</font></b></a></td></tr>"
+"</table>"
+"</div>");
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" ></span>';}
var my=setTimeout("go()",50);
}
setTimeout("go()",6000);
//-->
</script>
<body topmargin="0" leftmargin="0">
<div align="center"><span id="ads" ></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

一个非常棒的播放器,可惜如果图片是非常大的话,那结果有点惨!
