Navbar悬停没有显示
我从头开始构建简单的Web模板。 我使用旧式jquery在导航栏上进行悬停以显示列表<li> ，但它仅适用于“关于我们”列，并且不适用于“产品”列。
哪里不对？ 我应该怎么做？
HTML页面
<!DOCTYPE html>

<head>
<meta charset="utf-8"/>
<title>Template</title>

<script src="<?php echo base_url();?>js/jquery-3.0.0.min.js"></script>
<link rel="stylesheet" type="text/css" href="<?php echo base_url();?>css/style.css">
<script>
$(document).ready(function(){
$("#nav ol li").hover(function(){
$("ol",this).show(); //when onmouseover //ol ใน nav ol li อีกชั้นนึง
},
function(){ //when mouseout
$("ol",this).hide();
});
});
</script>
</head>

修正了下面代码中的</li>标签，并用$(this).find("ol")替换了$("ol",this) $(this).find("ol") 。 似乎工作：http://codepen.io/8odoros/pen/wzALyq
<li><a href="#">About us</a>
<ol>
<li><a href="#">ประวัติ</a></li>
<li><a href="#">xxxxx</a></li>
<li><a href="#">xxxxxx</a></li>
</ol>
</li>
<li><a href="#">Product</a>
<ol>
<li><a href="#">xxxxx</a></li>
<li><a href="#">xxxxx</a></li>
<li><a href="#">xxxxxx</a></li>
</ol>
</li>
你可以简单地使用这个css ，为什么使用jquery
#nav ol li ol {
display:none;
}
#nav ol li:hover > ol {
display:block;
} Hello检查下面的提琴完整<li>标签结束
menuFiddle
<li><a href="#">Product</a>
<ol>
<li><a href="#">xxxxx</a></li>
<li><a href="#">xxxxx</a></li>
li><a href="#">xxxxxx</a></li>
</ol></li>
