Reload page by stripping page from URL

From a Drupal JS app.

x-drupal-reload.js

var path = window.location.pathname, // /foo/bar/baz
    current_page = path.substring( path.lastIndexOf('/') ), // get everything after the last slash
    current_page_reloaded = path.replace(current_page, '/'); // strip everything after the last slash
    
// reload /foo/bar rather than /foo/bar/baz
window.location.href = window.location.origin + current_page_reloaded;
