1. $('#comment').click(function(e) { e.preventDefault(); $('#comment').slideDown(); }); }

And this html code:

1. 
   

   <div id="comment" class="alert alert-info" style="margin-top: 20px; display: none;"></div> <button type="button" class="btn btn-default btn-sm" id="route_update">Edit</button>

   
   

it should, if successful, slide down with the message...But it doesn't, the blue bar won't go down(it's not displayed).

Any suggestions? Any help will be appreciated
