<html> <head> <title> new document </title> <meta content="text/html; charset=utf-8" /> <script src="jquery/jquery-2.2.4.min.js"> </script> <style type="text/css"> .c1{ color: red; } </style> </head> <body> <div id="div" class="c1">hello world</div> <button id="button"> click me</button> </body> <script type="text/javascript"> $("#button").on("click", function(){ $("#div").toggleClass('c1'); }); </script> </html>
