<head>
<script src="https://code.jquery.com/jquery-git.js"></script>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Check whether the event namespace is used.</title>
</head>
<body>
<button>Display event.namespace</button>
<p></p>
</body>
</html>

JavaScript Code :

$( "p" ).on( "test.myNamespace", function( event ) {
console.log(event.namespace );
