The example in this article describes how jQuery uses the toggleClass method to dynamically add and delete Class styles. Share it with everyone for your reference. The specific analysis is as follows:

jQuery dynamically adds and deletes Class through the toggleClass method. One execution is equivalent to addClass, and another execution is equivalent to removeClass. Run the following code and click the button to see the text paragraph font switching between blue and black 

<!DOCTYPE html>
<html>
<head>
<script src="js/jquery.min.js">
</script>
<script>
$(document).ready(function(){
 $("button").click(function(){
  $("h1,h2,p").toggleClass("blue");
 });
});
</script>
<style type="text/css">
.blue
{
color:blue;
}
</style>
</head>
<body>
<h1>Heading 1</h1>
<h2>Heading 2</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Toggle class</button>
</body>
</html>

I hope this article will be helpful to everyone’s jQuery programming.
