代码如下:
<BODY>
//借助于marquee
<MARQUEE behavior="scroll" contenteditable="true" onstart="this.firstChild.innerHTML+=this.firstChild.innerHTML;" scrollamount="3" width="100">
<SPAN unselectable="on">这里是要滚动的内容</SPAN>
</MARQUEE>
//普通的实现方法
<DIV id="scrollobj" style="white-space:nowrap;overflow:hidden;width: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>
</BODY>
