<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8"/>
  <title></title>
  <style>
   *{
   margin:0px;
   padding:0px;
   }
   .li{
   list-style:none;
   }
   #p1{
   width:200px;
   text-align:center;
   font:30px/60px "simhei";
   }
   #p2{
   width:200px;
   border:1px solid black;
   }
   ul{
   margin-top:10px;
   border:1px solid black;
   display:none;
   }
   li{
   height:60px;
   }
   li:hover{
   background-color:blue;
   color:white;
   }
  </style>
 </head>
 <html>
  <p id ="p1">
   <p id="p2">设置</p>
    <ul id="oul">
     <li>搜索设置</li>
     <li>高级设置</li>
     <li>关闭预测</li>
     <li>搜索历史</li>
    </ul>  
  </p>
 </html>
 <script>
  document.getElementById('p1').onmouseover=function(){
   document.getElementById('oul').style.display='block';
  }
  document.getElementById('p1').onmouseout=function(){
   document.getElementById('oul').style.display='none';
  }
 </script>
</html>

Copy after login

When passing the variable name var, you can continue to implement:

var op1=document.getElementById('p1');
    var oul=document.getElementById('oul');
    op1.onmouseover=function(){
      oul.style.display='block';
    }
    op1.onmouseout=function(){
      oul.style.display='none';
    }

Copy after login

You can also control hiding and display through transparent opacity and height. .
