回答1:

Your jQuery function to add the click handler to the button, and to open the modal window should both work. See the example below. I can only suggest you to take a look at for example Chrome's DevTools to see if you have any JavaScript errors in its console.

$(document).ready(function(){
  $('#btn').click(function(){
    $('#server_msg_modal').modal('show');
   });
});

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet" />
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script>

<div class="btn btn-danger" href="#server_msg_modal" data-toggle="modal">using data attribute</div>

<div class="btn btn-danger" id="btn">using jQuery click handler</div>


<div class="modal fade" id="server_msg_modal">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>Modal body</p>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->
