//1
var type=2;   //广告显示的类别，1图片,2falsh
 var left_ads="";  //左边广告
 var right_ads="";  //右边广告
 if(type==1){   //广告为图片
  left_ads="<a href='#' target='_blank'><img src='left.gif' width='95' height='300' border='0' alt='欢迎访问本站'></a>"
  right_ads="<a href='#' target='_blank'><img src='rig.gif' width='95' height='300' border='0' alt='欢迎访问本站'></a>"
 }
 else if(type==2){   //广告为flash
  left_ads=reloadfalsh('300','90','swf/ad_right.swf','yes');
  right_ads=reloadfalsh('300','90','swf/ad_right.swf','yes');
 }
 suspendcode="<DIV id=lovexin1 style='Z-INDEX: 10; LEFT: -0px; POSITION: absolute; TOP: 100px; width: 90; height: 203px;'>"+left_ads+"</DIV>"

 document.write(suspendcode);
 lastScrollY=0;
 function heartBeat(){

 percent=.3*(diffY-lastScrollY);
 if(percent>0)percent=Math.ceil(percent);
 else percent=Math.floor(percent);
