核心代码:
复制代码 代码如下:
 
<div class="blockB" collection="Y" > 
<h2><span>王牌栏目 Regular features</span></h2> 
<div id="regular_features" class="pp"> 
<div class="tabs"> <a class="on" href=><ul> 
<li><a href=><li><a href=><li><a href=><li><a href=></ul> 
</div> 
<script type="text/javascript"> 
jQuery(function (j) { 
var r = j('#regular_features'), 
btns = r.find('> div.tabs > a'), 
el_ani = r.find('> ul'), 
el_pages = el_ani.find('> li'), 
pages = el_pages.length, 
p = 0, 
pw = 219; 
btns.each(function (idx, btn) { 
btn = j(btn); 
btn.mouseenter(function (ev) { 
if (idx != p) { 
j(btns[p]).removeClass('on'); 
btn.addClass('on'); 
p = idx; 
el_ani.stop().animate({ top: -pw * idx }, 300); 
} 
return false; 
}); 
}).eq(1).mouseenter(); 
}); 
</script> 
</div>
