添加Toggle class

$el.toggleClass('btn-primary btn-danger');

jQuery(function($) {
  $('#swapFire').on('click', function() {
    var $el = $(this),
      textNode = this.lastChild;
    $el.find('span').toggleClass('glyphicon-fire glyphicon-tint');
    $el.toggleClass('btn-primary btn-danger');

    $el.toggleClass('showFire');
 
  });
});

.btn {
  margin: 20px;
}

<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
