广告JS代码效果大全
1.[普通效果]
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，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，下面就是实现效果所需代码：（转自有问必答网shenzhidao.com)
var delta=0.015
var collection;
function floaters() {
this.items = [];
this.addItem =
function(id,x,y,content) document.write('<DIV id='+id+' style="Z-INDEX: 0; POSITION: absolute; width:80px; height:60px;left:'+(typeof(x)=='string'?eval_r(x):x)+';top:'+(typeof(y)=='string'?eval_r(y):y)+'">'+content+'</DIV>'); var newItem = {};
newItem.object = document.getElementByIdx_x(id);
newItem.x = x;
newItem.y = y; this.items[this.items.length] = newItem; this.play =
function() collection =
this.items
setInterval('play()',10); }
function play() if(screen.width<=800) 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_r(collection.x):collection.x);
var followObj_y = (typeof(collection.y)=='string'?eval_r(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 = ''; } var theFloaters =
new floaters();
theFloaters.addItem('followDiv1','document.body.clientWidth-100',0,'</a><br><a href=广告链接地址 target=_blank><img src=广告图片地址 width=100 height=400border=0></a>' target=_blank);
theFloaters.addItem('followDiv2',0,0,'<br><a href=广告链接地址 target=_blank><img src=广告图片地址 width=100 height=400 border=0></a>' target=_blank);
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调用即可！注意修改广告图片地址和连接地址！
