页面代码：
问题：只显示前面3个的11|（即显示红色部分），后面的隐藏掉，当鼠标移到“图书 >”时才全部显示出来，不知道怎么做？添加什么的jq代码。
回复讨论(解决方案)
补充：全部显示出这些内容如下
<script type="text/javascript" src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script><div id="bbb">图书 ></div><div id="aaa"> <li style="float:left;">11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li></div><script type="text/javascript">function lishow() { $("#aaa li").show();}function lihide() { $("#aaa li").slice(3).hide();}$(lihide);var timer;$("#bbb").mouseenter(function(event){ lishow();}).mouseleave(function(event){ timer = setTimeout(lihide, 300);});$("#aaa").mouseenter(function(event){ clearTimeout(timer);}).mouseleave(function(event){ lihide();});</script> 2楼大神，功能是实现了。但是如果后面还有类似图书的层就不能用了。
如果我想图书2（图书3...） 也实现同样的功能。怎么修改。
<script type="text/javascript" src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script><div class="bbb">图书1 ></div><div> <li style="float:left;">11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li></div><div class="bbb">图书2 ></div><div> <li style="float:left;">11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li> <li style="float:left;">|11</li></div><script type="text/javascript">function lishow(t) { $(t).next().find("li").show();}function lihide(t) { $(t).find("li").slice(3).hide()}$(function() { $(".bbb").each(function() { lihide($(this).next()); });});var timer;$(".bbb").mouseenter(function(event){ lishow(this);}).mouseleave(function(event){ var t = $(this).next(); timer = setTimeout(function() { lihide(t); }, 300);});$(".bbb").next().mouseenter(function(event){ clearTimeout(timer);}).mouseleave(function(event){ lihide(this);});</script> 大神，辛苦你了。我就想做网易云阅读的那样。http://yuedu.163.com/。
