高分请教一个超简单的无限制滚动问题

是不是这样滚动
<div id="marquees">
  <a href="javascript:">1,你可曾有过无数的梦想，</a><br>
  <br>
  <a href="javascript:">2,却在时光的流逝里幻灭 </a><br>
  <br>
  <a href="javascript:">3,你可曾对未来期待憧憬，</a><br>
  <br>
  <a href="javascript:">4,却在成长的岁月中迷失</a><br>
  <br>
</div>
<script language="JavaScript">marqueesHeight=200;
stopscroll=false;with(marquees){
  style.width=0;
  style.height=marqueesHeight;
  style.overflowX="visible";
  style.overflowY="hidden";
  noWrap=true;
  onmouseover=new Function("stopscroll=true");
  onmouseout=new Function("stopscroll=false");
}
document.write('<div id="templayer" style="position:absolute;z-index:1;visibility:hidden"></div>');preTop=0; currentTop=0; function init(){
  templayer.innerHTML="";
  while(templayer.offsetHeight<marqueesHeight){
    templayer.innerHTML+=marquees.innerHTML;
  }
  marquees.innerHTML=templayer.innerHTML+templayer.innerHTML;
  setInterval("scrollUp()",20);//越大越慢
}
document.body.onload=init;function scrollUp(){
  if(stopscroll==true) return;
  preTop=marquees.scrollTop;
  marquees.scrollTop+=1;
  if(preTop==marquees.scrollTop){
    marquees.scrollTop=templayer.offsetHeight-marqueesHeight;
    marquees.scrollTop+=1;
  }
}

差不多就是clare2003(忘情火)和sparks345(sparks345) 的结合体了,sparks345的这个如果把那个高度设置成100请看一下效果,当滚到一定程度的时候会自动跳到头上去,怎么把这个问题解决?
if(currentTop1==21) 是每次向上滚动的高度；
if(icefable11.scrollTop==78) 是向上滚动多少以后重新开始滚动；调着试一下吧~~
有必要弄那么复杂的吗？<style>a{display:block;font-size:15px};</style>

var t=setInterval(myfunc,1000)
var d=document.getElementById("div1")
function myfunc(){
var o=d.firstChild
d.removeChild(o)
d.appendChild(o)

d.onmouseover=function(){clearInterval(t)}
d.onmouseout=function(){t=setInterval(myfunc,1000)}
</script>
setInterval(myfunc,1000)  //这里改一下调时间，1000是1秒钟滚动一次，可根据需要改height:68px;overflow:hidden  // 68px 这里是根据你内容的行数和字体大小改显示区域的高度
比如，我设置的字体大小为15px, 如果只要显示一行的话，就是<div id="div1" style="width:300px;height:15px;overflow:hidden">
