  <p>every one can navigate to Page3, I'm using this code:</p>
  
  <pre><code>        $('#Page3').on('pageshow', function (object) {
              //  Change enabled status 
              $('#MenuItemEnPedido').find('a').each(function () {
                  $(this).addClass('ui-disabled');
              });
