Below I will share with you a JS method to implement the delayed hiding function (similar to QQ avatar mouse placement to display information), which has a good reference value and I hope it will be helpful to everyone.

JS implements delayed hiding

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>延迟隐藏</title>
 <style>
 #p1{
  width:100px;
  height:100px;
  background:yellow; 
  border: 5px solid #999;
  border-radius: 10px;
  position: absolute;
  right: 50px;
  text-align: center;
  line-height: 100px;
  margin-bottom:10px;
 }
 #p2{
  width:200px;
  float: left;
  height:200px;
  border: 5px solid #999;
  border-radius: 10px;
  position: absolute;
  right:160px;
  text-align: center;
  line-height: 200px;
  background:green;
  display:none;
 }
</style>

<script>
 window.onload=function(){
  var p1=document.getElementById("p1");
   p1.innerHTML="鼠标请放上！";
  var p2=document.getElementById(&#39;p2&#39;);
   p2.innerHTML="鼠标请移开！";
  var timer=null;
  p1.onmouseover= function(){  
    clearTimeout(timer);
    p2.style.display=&#39;block&#39;;
  };
   p1.onmouseout= function(){
   clearTimeout(timer);
    timer= setTimeout(function(){
      p2.style.display=&#39;none&#39;;
    }, 700);
  };
  p2.onmouseover=function(){
   clearTimeout(timer);
  };
  p2.onmouseout=function(){
   clearTimeout(timer);
    timer=setTimeout(function(){p2.style.display=&#39;none&#39;;},700);   
  }
 }
</script>
</head>
<body>
<p id="p1"></p>
<p id="p2"></p>
 
</body>
</html>

The above is what I compiled for everyone. I hope it will be useful to you in the future. Everyone is helpful.
