jquery code:

<script> $(document).ready(function() {     $('#v-btn').click(function() {         alert("im here");         $('.sub-nav').toggleclass('visible');     }); }); </script>

set @ top:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

here css process:

#content-content.sub-nav{     display: none; }   #content-content.visible {     display: block; } 

$('#v-btn').click(function() {                 var $elem = $(this).find('h6 > b');     $elem.text(); // vvvvvv     alert("im here");     $('.sub-nav').toggleclass('visible'); });
