marquee和js两种方法,我建议使用js的,marquee兼容性不好,只兼容IE浏览器。

用marquee实现首尾相连循环滚动效果(仅IE):<br /><br />
<MARQUEE behavior="scroll" contenteditable="true" onstart="this.firstChild.innerHTML+=this.firstChild.innerHTML" scrollamount="3" width="100"><SPAN unselectable="on"><img src="img/menu_trigger.png"><img src="img/menu_trigger.png"><img src="img/menu_trigger.png"><img src="img/menu_trigger.png"><img src="img/menu_trigger.png"></SPAN></MARQUEE>
<br /><br />用DIV+javascript实现首尾相连循环滚动效果(兼容firefox):<br /><br />
<DIV id="scrollobj" style="white-space:nowrapoverflow:hiddenwidth:500px"><span>这里是要滚动的内容</span></DIV>
<script language="javascript" type="text/javascript">
<!--
function scroll(obj) {
var tmp = (obj.scrollLeft)++
//当滚动条到达右边顶端时
if (obj.scrollLeft==tmp) obj.innerHTML += obj.innerHTML
//当滚动条滚动了初始内容的宽度时滚动条回到最左端
if (obj.scrollLeft>=obj.firstChild.offsetWidth) obj.scrollLeft=0
}
setInterval("scroll(document.getElementById('scrollobj'))",20)
//-->
</script>

望采纳!
