很好玩的一款广告特效代码，广告图片像一个弹球一样从天而降，然后慢慢稳下来，躲进屏幕一侧，有点像漂浮广告的形式。

<html><head><title>跳球广告代码</title><script>var brOK=false;var mie=false;var aver=parseInt(navigator.appVersion.substring(0,1));var aname=navigator.appName;var mystop=0;var step=0.2;function checkbrOK(){if(aname.indexOf("Internet Explorer")!=-1){if(aver>=4) brOK=navigator.javaEnabled();mie=true;}if(aname.indexOf("Netscape")!=-1)  {if(aver>=4) brOK=navigator.javaEnabled();}}var vmin=1.5;var vmax=3;var vr=2;var timer1;function Chip(chipname,width,height){this.named=chipname;this.vx=vmin+vmin;this.vy=0;this.w=width;this.h=height;this.xx=0;this.yy=0;this.timer1=null;}function movechip(chipname){if(brOK  &&  mystop==0){eval("chip="+chipname);if(!mie){pageX=window.pageXOffset;pageW=window.innerWidth;pageY=window.pageYOffset;pageH=window.innerHeight;}else{pageX=window.document.body.scrollLeft;pageW=window.document.body.offsetWidth-8;pageY=window.document.body.scrollTop;pageH=window.document.body.offsetHeight+15;} chip.xx=chip.xx+chip.vx;chip.vy=chip.vy+step;chip.yy=chip.yy+chip.vy;if(chip.xx<=pageX){chip.xx=pageX;chip.vx=vmin;}if(chip.xx>=pageX+pageW-85){chip.xx=pageX;chip.vx=vmin;chip.yy=pageY;chip.vy=vmin+vmax;}if(chip.yy>(pageY+pageH-chip.h)){chip.yy=pageY+pageH-chip.h;chip.vy=-chip.vy*0.65;}if(!mie){eval('document.'+chip.named+'.top ='+chip.yy);eval('document.'+chip.named+'.left='+chip.xx);} else{eval('document.all.'+chip.named+'.style.pixelLeft='+chip.xx);eval('document.all.'+chip.named+'.style.pixelTop ='+chip.yy); }    chip.timer1=setTimeout("movechip('"+chip.named+"')",20);}}function stopme(flag){brOk=true;mystop=flag;movechip("tome");}var tome;var chip;function tome(){checkbrOK(); tome=new Chip("tome",80,80);if(brOK  &&  mystop==0) { movechip("tome");}}ns4=(document.layers)?true:false;ie4=(document.all)?true:false;function cncover(){if(ns4){    document.cnc.left=window.innerWidth/2-400;    eval('document.cnc.top=document.'+chip.named+'.top');    document.cnc.visibility="show";    stopme(1);    mytime=setTimeout("cncout()",3000);    }else if(ie4)     {    document.all.cnc.style.left=window.document.body.offsetWidth/2-400;    document.all.cnc.style.top=parseInt(document.all.tome.style.top);    document.all.cnc.style.visibility="visible";    stopme(1);    mytime=setTimeout("cncout()",3000);    }}function cncout(){clearTimeout(mytime);if(ns4){    document.cnc.visibility="hide";    stopme(0);    }else if(ie4)     {    document.all.cnc.style.visibility="hidden";    stopme(0);    }    }onload=tome;</script></head><body><div id="tome" style="position:absolute;"><img src="/d/file/p/2024/09-05/fa5957de40751b2b59734598f1dc0480.gif" border=0></div></body></html>
