页面两侧对联广告代码效果
<p>页面两侧对联广告代码效果</p><p>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：</p><p> var delta=0.015<br/> var collection;<br/> function floaters() {<br/> this.items = [];<br/> this.addItem = function(id,x,y,content)<br/> {<br/> 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>');<br/> <br/> var newItem = {};<br/> newItem.object = document.getElementById(id);<br/> newItem.x = x;<br/> newItem.y = y;</p><p> this.items = newItem;<br/> }<br/> this.play = function()<br/> {<br/> collection = this.items<br/> setInterval('play()',10);<br/> }<br/> }<br/> function play()<br/> {<br/> if(screen.width<=800)<br/> {<br/> for(var i=0;i<collection.length;i++)<br/> {<br/> collection.object.style.display = 'none';<br/> }<br/> return;<br/> }<br/> for(var i=0;i<collection.length;i++)<br/> {<br/> var followObj = collection.object;<br/> var followObj_x = (typeof(collection.x)=='string'?eval(collection.x):collection.x);<br/> var followObj_y = (typeof(collection.y)=='string'?eval(collection.y):collection.y);</p><p> if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {<br/> var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;<br/> dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));<br/> followObj.style.left=followObj.offsetLeft+dx;<br/> }</p><p> if(followObj.offsetTop!=(document.body.scrollTop+followObj_y)) {<br/> var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta;<br/> dy=(dy>0?1:-1)*Math.ceil(Math.abs(dy));<br/> followObj.style.top=followObj.offsetTop+dy;<br/> }<br/> followObj.style.display = '';<br/> }<br/> } <br/> <br/> var theFloaters = new floaters();<br/> 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>');<br/> 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>');<br/> theFloaters.play(); </p><p>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！</p><br /><br /><blockquote class="blockquote">From: http://askwz.cn/read.php?tid=119Powered by PHPWind.com</blockquote>
