                A snippet to use for AJAX; robustness in the face of 401 and other errors
              
          
    Handles 401 errors for OAuth users following the 'code flow' (redirects) and notifies the user if there is a fatal error. You wouldn't want the server giving your users 401s outright though -- only when the request is AJAX (X-Requested-With: XMLHttpRequest.)
Uses jQuery (obviously) as well as Bootstrap modals. I'm not using PJAX just yet but I will include it when I do.
In the following example, I've placed the following elements as the last children of the <body> element. Note the addition of the empty data-remote attribute on #dynamic-modal -- this prevents Bootstrap from performing a redundant load the first time the modal is used.
<div class="modal fade special" id="error-modal" tabindex="-1" role="dialog">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
