求下面一段代码的详细注释,本人新手,所以不详细可能看不懂!
<SCRIPT language=JavaScript>
lastScrollY=0;
function heartBeat(){
diffY=document.body.scrollTop;
percent=.1*(diffY-lastScrollY);
if(percent>0)percent=Math.ceil(percent);
else percent=Math.floor(percent);
document.all.lovexin12.style.pixelTop+=percent;
document.all.lovexin14.style.pixelTop+=percent;
lastScrollY=lastScrollY+percent;
}
suspendcode12="<DIV id=lovexin12 style='left:10px;POSITION:absolute;TOP:220px;'><A HREF='http://218.28.193.215/jc1_report.asp?bz=郑州' target='_blank'><img src='http://218.28.193.215/jc1.gif' border=0 width='75' height='130'></A></div>"
document.write(suspendcode12);
suspendcode14=
<SCRIPT language=JavaScript>
lastScrollY=0;
function heartBeat(){
diffY=document.body.scrollTop;
percent=.1*(diffY-lastScrollY);
if(percent>0)percent=Math.ceil(percent);
else percent=Math.floor(percent);
document.all.lovexin12.style.pixelTop+=percent;
document.all.lovexin14.style.pixelTop+=percent;
lastScrollY=lastScrollY+percent;
}
suspendcode12="<DIV id=lovexin12 style='left:10px;POSITION:absolute;TOP:220px;'><A HREF='http://218.28.193.215/jc1_report.asp?bz=郑州' target='_blank'><img src='http://218.28.193.215/jc1.gif' border=0 width='75' height='130'></A></div>"
document.write(suspendcode12);
suspendcode14=
1.是全的。
2.代码功能：每隔1毫秒调整两张警察图片的相对位置，让他们保持在窗口下方。
3.注释：
<SCRIPT language=JavaScript>
lastScrollY=0; //记录上次的滚动偏移量
function heartBeat(){
diffY=document.body.scrollTop; //当前的偏移量
percent=.1*(diffY-lastScrollY); //与上次的偏移量相比所得一个参考量
if(percent>0)percent=Math.ceil(percent); //如果滚动条往下滚动，则上取整
else percent=Math.floor(percent); //如果滚动条网上滚，则下取整
document.all.lovexin12.style.pixelTop+=percent; //调整图片的位置，下同
document.all.lovexin14.style.pixelTop+=percent;
lastScrollY=lastScrollY+percent; //将新的偏移量写入这个，备下次调用函数时参考
}
