Answer 3

下面就是代码了。..
id不要随便改哟~~要改的话就要,e.g:把所有所有的article1替换掉,
<div id="article1" style="width:189;"> 
aaaa<br>
bbb<br>
adasdf<br>
fqeaqdf<br>
qowe<br>
afsdf<br>
asdf<br>
asdfqwe<br>
fqwefasd<br>
fqwe
</div>
<div id="article2" style="position:absolute;z-index:1;visibility:hidden"></div> <script language="javascript"> 
articleHeight=140; 
stopscrolla=false; 
article1.scrollTop=0; 
with(article1){ 
style.width=0; 
style.height=articleHeight; 
style.overflowX="visible"; 
style.overflowY="hidden"; 
noWrap=true; 
onmouseover=new Function("stopscrolla=true"); 
onmouseout=new Function("stopscrolla=false"); 
} preTopa=0; currentTopa=0; stoptimea=0; function init_srolltext1(){ 
article2.innerHTML=""; 
article2.innerHTML+=article1.innerHTML; 
article1.innerHTML=article2.innerHTML+article2.innerHTML; 
setInterval("scrollUp1()",50); 
} 
function scrollUp1(){ 
if(stopscrolla==true) return; 
currentTopa+=1; 
if(currentTopa==140) 
{ 
stoptimea+=1; 
currentTopa-=1; 
if(stoptimea==1) 
{ 
currentTopa=0; 
stoptimea=0; 
} 
} 
else { 
preTopa=article1.scrollTop; 
article1.scrollTop+=1; 
if(preTopa==article1.scrollTop){ 
article1.scrollTop=article2.offsetHeight-articleHeight; 
article1.scrollTop+=1; 
} 
} } 
init_srolltext1(); 
</script>

有不用javascript的方法吗,难道marquee没有解决这种办法的属性吗!
