<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<a href="urlLink">Press Me to see logs</a>
<a href="urlLink">Press Me to see logs in console</a>
<a href="#">Nothing will happen</a>
<script>
   $(function(){
      $("a:not([href='#'])").click(function(event){
         event.preventDefault();
         console.log("You have pressed me!!!!!");
