<p id="broadcast" class="bar" name="giftactive">
<p style="float:left"><strong>间隔滚动效果：</strong></p>
<p id="demo" style="overflow:hidden;height:22px;line-height:22px;">
<ul class="mingdan" id="holder">
<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_blank">aaaaaa</a></li>

</ul>
</p>
</p>
<script type="text/javascript">
function AutoScroll(obj) {
$(obj).find("ul:first").animate({
marginTop: "-22px"
}, 500, function() {
$(this).css({ marginTop: "0px" }).find("li:first").appendTo(this);
