jQuery mouse events mouseover() and mouseout() events

When you were learning JS, do you still remember that there are two methods called move-in and move-out events? onmouseover() and onmouseout() events~

jQuery also provides such events to monitor the user's move-in and move-out operations. The mouseover() and mouseout() events are similar in usage

Let's explain it through an example

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>mouseover()和mouseout()</title>
    <style type="text/css">
        div{
            width:200px;
            height:200px;
            border:1px solid #000;
        }
    </style>
    <script src="http://libs.baidu.com/jquery/1.9.1/jquery.js"></script>
</head>
<body>
    <div></div>


    <script>
         $("div").mouseover(function(){
            $('div').css("background",'red');
         })

         $("div").mouseout(function(){
             $('div').css("background",'green');
         })
    </script>
</body>
</html>

When the mouse is placed on the div tag, the background color will turn red, and when the mouse leaves the div tag, it will turn green
