页面两侧对联广告代码效果
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,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,下面文本框中就是实现效果所需代码:
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(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(),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(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 = ; } } 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=400 border=0></a>); 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>); 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!
