Operlapping Nicescroll scrolbars in Bootstrap tabs

问题

I'm using Nicescroll to display scrollbars on bootstrap tabs.

While it displays the scrollbars, if we initialize nicescroll on multiple tabs, the scroller from non-active tabs are also visible at all times.

This fiddle is a recreation of the issue: http://jsfiddle.net/LittleLebowski/B86me/15/ Here's the code: HTML code

<!-- Nav tabs -->
<ul class="nav nav-tabs">
  <li><a href="#home" data-toggle="tab">Home</a></li>
  <li><a href="#profile" data-toggle="tab">Profile</a></li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="home">
      <div class="scroller" data-height="150px">

  <div class="tab-pane" id="profile">
       <div class="scroller" data-height="150px">
           <p>In July 1978, Post-Newsweek exchanged WTOP-TV with the Evening News Association's WWJ-TV (now WDIV-TV) in Detroit.

      </div>
      </div>
</div>

JS code

$(document).ready(
    function() {
        $('.scroller').each(function () {
            $(this).height($(this).attr("data-height"));
            $(this).niceScroll({
                cursorwidth: '7px',
                cursorcolor: '#A1B2BD',
                cursoropacitymax: 0.6,
                autohidemode: false 
            });
        });
    }
  );

How can I show scrollbars only on the active tabs.

Kindly guide me. :(

I've solved this issue on my site with this code.

JS

<script>
         $(document).ready(function() {
                $('a[data-toggle="tab"]').click(function () {
           $(this).closest('.panel').find('.panel-body').niceScroll({
                        cursorcolor: "#2f6098",
                        cursorwidth: 10,
                        cursoropacitymin: 0.7
                    });

           if($(this).attr('aria-controls') == 'profile'){
            $(this).closest('.panel').find('.panel-body').getNiceScroll().show();
           }else{
            $(this).closest('.panel').find('.panel-body').getNiceScroll().hide();
           }
                })
            });
    </script>
