On Taobao, JD.com and other web pages, we can see that when the mouse is moved up, other options can appear below it. Now let’s demonstrate this function
It mainly uses the display in CSS, as well as the mouse-triggered events onmouseover() and onmouseout(), which can be achieved by adding CSS style settings and tags.
The details are as follows:
1. For better control, the list style is adopted, and it is very convenient when setting the css style
2. The tag style is adopted, which allows the mouse to move up to react to other tags
Specific functions written in js:

<script type="text/javascript"> 
    function open1(node){ 
      var node1=node; 
      var nodes=node1.getElementsByTagName("ul")[0]; 
      with(nodes.style){ 
        display= (display=="block")&#63; "none" : "block"; 
      } 
    } 
</script>

Code of html part:

<div id="news"> 
    <ul id="newsid1"> 
      <li onmouseover="open1(this)"; onmouseout="open1(this)"> 
        <!--<a href="javascript:void(0)" onmouseover="open1(this)"; onmouseout="open1(this)" >最新新闻</a> 在这里，移动第一个之后就会消失，不能够点击下面的--> 
        <a href="javascript:void(0)">最新新闻</a> 
                <ul><!--这样包装为了能更好的封装下面的内容，到时候鼠标移动上面，就能对下面的这个操作了--> 
          <li><a href="http://www.baidu.com">最新新闻内容摘要《机密》1</a></li> 
          <li><a href="http://www.baidu.com">最新新闻内容摘要《机密》2</a></li> 
          <li><a href="http://www.baidu.com">最新新闻内容摘要《机密》3</a></li> 
          <li><a href="http://www.baidu.com">最新新闻内容摘要《机密》4</a></li> 
          <li><a href="http://www.baidu.com">最新新闻内容摘要《机密》5</a></li> 
        </ul> 
      </li> 
      <li onmouseover="open1(this)"; onmouseout="open1(this)"> 
        <a href="javascript:void(0)" onclick="">新浪新闻</a> 
        <ul> 
           <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》1</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》2</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》3</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》4</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》5</a></li> 
        </ul> 
      </li> 
      <li onmouseover="open1(this)"; onmouseout="open1(this)"> 
        <a href="javascript:void(0)" onclick="">社会新闻</a> 
        <ul> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》1</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》2</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》3</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》4</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》5</a></li> 
        </ul> 
      </li> 
      <li onmouseover="open1(this)"; onmouseout="open1(this)"> 
        <a href="javascript:void(0)" onclick="">最新新闻</a> 
        <ul> 
           <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》1</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》2</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》3</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》4</a></li> 
          <li><a href="http://www.jb51.net">最新新闻内容摘要《机密》5</a></li> 
        </ul> 
      </li></ul></div>

In addition to the above being very important css settings are also very important, as follows:

<style type="text/css"> 
    #newsid1 { 
      list-style:none; 
    } 
    #newsid1 li ul{ 
      list-style:none; 
      margin:0px; 
      padding:0px; 
    } 
    #newsid1 li{ 
      float:left;/*让其并排显示*/ 
      width:220px; 
      text-align:center; 
      background-color:#80ff00; 
      /*设置宽度，让每一列平均显示*/ 
    } 
    #newsid1 li a{ 
      color:#8080ff; 
      text-decoration:none;/*让超链接下面没有横线*/ 
      text-align:center; 
      line-height:30px; 
       
    } 
    #newsid1 li a:hover{ 
      /*a:hover移上去有反应设置的具体的颜色和背景颜色 
*/ 
      color:#400080; 
      background-color:#ffffff; 
    } 
    #newsid1 li ul li{ 
      line-height:30px; 
      color:#ff8040; 
      background-color:#808000;; 
    } 
    #newsid1 li ul{ 
      display:none;/*默认的必须全部隐藏，然后在鼠标移上去触发时间之后设置 dispaly:block; 
*/ 
    } 
  </style>
