What I bring to you this time is how to use JS to switch between hiding and displaying and switching icons at the same time. This article will give you a good analysis.

HTML code:

<!doctype html>
<html>
<head> 
<meta charset=" utf-8"> 
<title>jq隐藏显示图标切换</title>
 <!--引入jq文件-->
<script type="text/javascript" scr="./js/jquery.min.js"></script>
</head>
<body>
<!--隐藏／显示 控制按钮-->
<p><img id="ctr" scr="./images/01.jpg"></p>
<!--被控制元素-->
<p id="info" style="display:none;">这里是要显示或隐藏的内容</p>
</body>
</html>

JS code:

$(document).ready(function(){
//通过id="ctr"获取元素click事件
   $("#ctr").click(function(){
//将显示和隐藏两个状态下的显示图标路径放入images变量中
    var images=[&#39;./images/01.jpg&#39;,&#39;./images/02.jpg&#39;];
//通过class的值来判断控制显示的图标样式
    if($("#ctr").attr("class")=="down"){
    $("#ctr").attr("src",images[0]);
    $("#ctr").removeClass();
    }else{
    $("#ctr").attr("src",images[1]);
    $("#ctr").addClass("down");
    }
//用于控制元素的隐藏或显示 主要方法toggle(),300是控制元素显示或隐藏的速度
    $("#info").toggle(300);
  });  
});
