注意：此效果任何模 板可以通用！！
一、将顶部滚动JS代 码保存为gundong.js文 件拷贝到根目 录JS文件夹里
二、在首页模板文件index.dwt的<head></head>标签之间添加代 码：
<script src=”js/gundong.js” language=”JavaScript” type=”text/javascript”></script>
三、找到要修改的展示产品的库文件，比如要修改产 品上架的滚动效果
在library文件夹里找到recommend_new.lbi文件在最上面添加代码：
<SCRIPT defer>
new Marquee(“textdiv”,0,4,760,229,1,3000,1)
</SCRIPT>
然 后在<div id=”show_new_area”>之前添加代码：
<div id=textdiv>
结尾记得要添加</div>
这样就OK了~
—————————————————————–
代 码实例：recommend_new.lbi的修改代码如下：
<SCRIPT defer>
new Marquee(“textdiv”,0,4,760,229,1,3000,1)
</SCRIPT>
<meta http-equiv=”Content-Type” content=”text/html; charset=gbk”>
<!– {if $new_goods} –>
<!– {if $cat_rec_sign neq 1} –>
<div >
<h3>
<div id=”itemNew”>
{if $cat_rec[2]}
<h2><a href=”javascript:void(0)”>{$lang.all_goods}</a></h2>
{foreach from=$cat_rec[2] item=rec_data}
<h2 ><a href=”javascript:void(0)”>{$rec_data.cat_name}</a></h2>
{/foreach}
{/if}
</div>
<a href=”../search.php?intro=new”><img src=”images/bnt_more_1.gif” /></a>
<span></span>
</h3>
</div>
<DIV >
<!– {/if} –>
<!–{foreach from=$new_goods item=goods}–>

<!– {else}–>
