Bootstrap 3 Collapse - adding active class to open panel

firstly here's the fiddle: http://jsfiddle.net/krish7878/h38jn324/

Simple question when a panel is clicked (and it expands to show it's respective content), a class 'active' needs to be added to 'panel-heading'.

I found similar question but none of those solutions seem to work (strangely). Any help would be appreciated.

HTML Code:

<div class="accordion-2 panel-group" id="accordion">
    <div class="panel panel-default">
        <div class="panel-heading">
            <h4 class="panel-title">
                <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
                    Our Mission
                </a>
            </h4>
        </div><!-- /.panel-heading -->
        <div id="collapseOne" class="panel-collapse collapse in">
            <div class="panel-body">
                <p>At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga.</p>
            </div>
        </div><!-- /#collapseOne -->
    </div><!-- /.panel -->
<div class="panel panel-default">
    <div class="panel-heading">
        <h4 class="panel-title">
            <a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">
                Success Stories
            </a>
        </h4>
    </div><!-- /.panel-heading -->
    <div id="collapseTwo" class="panel-collapse collapse">
        <div class="panel-body">
            <p>At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga.</p>
        </div><!-- /.panel-body -->
    </div><!-- /#collapseTwo -->
</div><!-- /.panel -->
<div class="panel panel-default last">
    <div class="panel-heading">
        <h4 class="panel-title">
            <a data-toggle="collapse" data-parent="#accordion" href="#collapseThree">
                Our Story
            </a>
        </h4>
    </div><!-- /.panel-heading -->
    <div id="collapseThree" class="panel-collapse collapse">
        <div class="panel-body">
            <p>At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga.</p>
        </div><!-- /.panel-body -->
    </div><!-- /#collapseTwo -->
</div><!-- /.panel -->

JS Code: 

jQuery('.accordion-2 .panel-heading a[data-toggle="collapse"]').on('click', function () {   
jQuery('.accordion-2 .panel-heading a[data-toggle="collapse"]').removeClass('actives');
$(this).addClass('actives');

});

All of the other answers require panel-heading. All this requires is the data-target. 

$('[data-toggle=collapse]').each(function() {
    var $collapse_btn = $(this),
        $collapse_target =  $(this.getAttribute('data-target'));

    $collapse_target.on('show.bs.collapse', function () {
        $collapse_btn.addClass('collapsed');
    }).on('hide.bs.collapse', function () {
        $collapse_btn.removeClass('collapsed');
    });
});

Try this:

$('.panel-heading a').click(function() {
    $('.panel-heading').removeClass('active');
    if(!$(this).closest('.panel').find('.panel-collapse').hasClass('in'))
        $(this).parents('.panel-heading').addClass('active');
});

Check JSFiddle Demo

Update 1: To set a panel as active by default on the first load, just add the active class manually to the panel-heading in HTML code.

Update 2: Although this answer is marked as accepted answer, I highly recommend to take a look at the Blizwire answer too.

For someone who is looking for CSS solution and I tired this only in Bootstrap 4:

HTML

<a class="collapsed" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample"> Open Collapse </a>

<div class="collapse" id="collapseExample">
  <div class="card card-block card-outline-primary">
    <h3 class="text-center">Date Goes Here</h3>
  </div>
</div>

CSS

[data-toggle="collapse"]:not(.collapsed) {
  background-color: blue;
}

The current answer (by Moshtaf) is using a standard click event. However, Bootstrap has a built-in event for opening/closing of collapsable items, as pointed out by Jurriaan, which is much safer to use (a click on the link doesn't necessarily mean that the panel is shown). Here's a clean solution, inspired by Jurriaan's solution, with minimal amount of code and jQuery selectors. http://codepen.io/martinkrulltott/pen/mPgYgQ 

$(document).ready(function() {
  $('.panel-collapse').on('show.bs.collapse', function () {
    $(this).siblings('.panel-heading').addClass('active');
  });

  $('.panel-collapse').on('hide.bs.collapse', function () {
    $(this).siblings('.panel-heading').removeClass('active');
  });
});

These answers didn't work for me for in some cases: Multiple panel groups on 1 page, or clicking on the same title to hide a panel. This adaption from https://stackoverflow.com/a/24033761/842740 works as a general solution and I added code for setting the default open panel on active state.

$('.panel-group .panel-collapse.in').prev().addClass('active');
$('.panel-group')
  .on('show.bs.collapse', function(e) {
    $(e.target).prev('.panel-heading').addClass('active');
  })
  .on('hide.bs.collapse', function(e) {
    $(e.target).prev('.panel-heading').removeClass('active');
  });

      <!-- /.panel-body -->
    </div>
    <!-- /#collapseTwo -->
  </div>
  <!-- /.panel -->
</div>
<!-- /.accordion-2 -->

I think that this is more logical.
