Fade in and fade out

The animations of the hide() and show() functions are constantly changing the size. In fact, this approach is very confusing, so we are best at this time. A good practice is to perform fade-in and fade-out effects

Fade in operation: fadeIn(time, function(){})

Fade out operation: fadeOut(event, function(){})

Set the fade-out operation fadeTo(event, fade-out rate, function(){}) by yourself, the fade-out rate does not exceed 1

Fade-out operation

<html>
<head>
<meta charset="utf-8"/>
<title>jQuery的动画函数</title>
<script type="text/javascript" src="js/jQuery.min.js" charset="utf-8"></script>
<link rel="style/sheet" type="text/css" href="css/style.css"/>
<script type="text/javascript">
$(function(){
//设置层淡出操作
$(myimg).fadeOut(5000,function(){
$(this).fadeIn(5000)
});
});
</script>
</head>
<body>
<div id="myDiv">
<img  src="images/gd.jpg" id="myimg"    style="max-width:90%"/ alt="Implementation of jQuery fade-in and fade-out animation effects" >
</div>
</body>
</html>

Use fadeTo() to observe the fade-out rate Question

$(function(){
//设置淡出率
$(myimg).fadeTo(5000,0.3,function(){});
});

If set to 0, it means complete fade out, if set to 1, it means no single fade out.

If you already know the fade-in and fade-out operations, you can implement a row of buttons

Use fade-in and fade-out to realize the function of the menu
