一款实用的对联广告代码

var showad = true;
var Toppx = 60;//上端位置
var AdDivW = 100;//宽度
var AdDivH = 360;//高度
var PageWidth = 800;//这个参数决定是否出现左右滚动条
var MinScreenW = 1024; //显示广告的最小屏幕宽度象素
var ClosebuttonHtml = '<div align="right" style="position: absolute;top:0px;right:0px;margin:2px;padding:2px;z-index:2000;"><a href="javascript:;" οnclick="hidead()" style="color:red;text-decoration:none;font-size:12px;">Close</a></div>'
var AdContentHtml = '<div align="center"><br><br><object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="​​​http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0​​​" width="97" height="233"><param name="movie" value="images/ad-02.swf"><param name="quality" value="high"><embed src="images/ad-02.swf" quality="high" pluginspage="​​http://www.macromedia.com/go/getflashplayer​​​" type="application/x-shockwave-flash" width="97" height="233"></embed></object></div>';
document.write ('<div id="Javascript.LeftDiv" style="position: absolute;border: 1px solid #336699;background-color:#EEEEE2;z-index:1000;width:'+AdDivW+'px;height:'+AdDivH+'px;top:-1000px;word-break:break-all;display:none;">'+ClosebuttonHtml+'<div>'+AdContentHtml+'</div></div>');
document.write ('<div id="Javascript.RightDiv" style="position: absolute;border: 1px solid #336699;background-color:#EEEEE2;z-index:1000;width:'+AdDivW+'px;height:'+AdDivH+'px;top:-1000px;word-break:break-all;display:none;">'+ClosebuttonHtml+'<div>'+AdContentHtml+'</div></div>');
function scall(){
 if(!showad){return;}
 if (window.screen.width<MinScreenW){
  //alert("临时提示：\n\n显示器分辨率宽度小于"+MinScreenW+",不显示广告");
  showad = false;
  document.getElementById("Javascript.LeftDiv").style.display="none";
  document.getElementById("Javascript.RightDiv").style.display="none";
  return;
 }
 var Borderpx = ((window.screen.width-PageWidth)/2-AdDivW)/2; document.getElementById("Javascript.LeftDiv").style.display="";
 document.getElementById("Javascript.LeftDiv").style.top=document.body.scrollTop+Toppx;
 document.getElementById("Javascript.LeftDiv").style.left=document.body.scrollLeft+Borderpx;
 document.getElementById("Javascript.RightDiv").style.display="";
 document.getElementById("Javascript.RightDiv").style.top=document.body.scrollTop+Toppx;
 document.getElementById("Javascript.RightDiv").style.left=document.body.scrollLeft+document.body.clientWidth-document.getElementById("Javascript.RightDiv").offsetWidth-Borderpx;
}function hidead()
{
 showad = false;
 document.getElementById("Javascript.LeftDiv").style.display="none";
 document.getElementById("Javascript.RightDiv").style.display="none";
}
window.οnscrοll=scall;
window.οnresize=scall;
window.οnlοad=scall; 
只需把以上的代码放到一个js文件,在想要显示广告的地方引用这个文件即可
AdContentHtml 为广告内容区，可以随意更改，如本例放的是一个flash文件，也可以改成放图片及文字链等
