求div里js滚动遇到的问题. 代码是文字滚动从下向上滚动.

<div id="latest_site_news" class="colbox">
<h3> <!-- {if $site_news.info.page_count gt 1} --> <em class="more"> <a href="{url src=index.php?app=article&act=site_news}">{$lang.more} </a> </em> <!-- {/if} -->{$lang.site_news} </h3>
<div id="news_scroll_bar" style="overflow:hidden; height:180px;">
<div id="news_scroll_items" class="colboxcontent">
<ul>
<!-- {foreach from=$site_news.data item=article} -->
<li> <a href="{url src=index.php?app=article&act=site_news&id=$article.article_id}">{$article.title|escape} </a> </li>
<!-- {/foreach} -->
</ul>
</div>
<div id="news_scroll_replaces" class="colbtm"> </div>
</div>
</div>
<script language="javascript">
var news_scroll_bar = document.getElementById("news_scroll_bar");
var news_scroll_items = document.getElementById("news_scroll_items");
var news_scroll_replaces = document.getElementById("news_scroll_replaces");
var speed = 70;//滚动速度
if(isFirefox=navigator.userAgent.indexOf("Firefox")>0){
var rows = 100;//每行高度
}

var stim = 10; //停留时间倍数 * speed
var stop = 10; //初始化值，不管

news_scroll_replaces.innerHTML=news_scroll_items.innerHTML
function Marquees(){

if(news_scroll_replaces.offsetTop-news_scroll_bar.scrollTop <=0)
news_scroll_bar.scrollTop-=news_scroll_items.offsetHeight
else{
news_scroll_bar.scrollTop++
}
}
var MyMars=setInterval(Marquees,speed)
news_scroll_bar.onmouseover=function() {clearInterval(MyMars)}
news_scroll_bar.onmouseout=function() {MyMars=setInterval(Marquees,speed)}
</script>


目前这段代码,走一走就停了. 而且速度有点慢. 求高人帮忙解决下.

这个就是现在用的比较多的滚动js,可要调制速度等等

详细效果见.wwww.web-pifa.com 站内快讯.

似乎不循环的样子. 刷新一下网站走一走,不刷新走一会就停了

如果效果类4:http://u.discuz.net/home/
右中哪个《看看大家现在正在做什么…》效果,我把他哪个js 类扣出来了在这:http://www.t6new.cn/include/js/scrollclass.js
调用方式:

          <ul id="scrollbody">          
                  <%Call topHumanIndex()%>
          </ul><script type="text/javascript">startMarquee(95, 60, 0, 'scrollbody');</script>

topHumanIndex过程打印的是<li>...<li>
