$(document).on('af_complete', function (event, response) {
      
          $('#getAQuoteModal').modal('hide');
          if (response.success) {
            $('#thanks').modal('show');
            
            let form = $(response.form[0]);
            form.attr('action', '-%thks');
            
            let url = window.location.href;
            
            if (url.match(/\?/)) {
                url += '&';
            } else {
                if (! url.match(/\/$/)) url += '/';
            };
            
            url += form.attr('action');
            history.pushState({}, '', url); 
            
            
          }

    });
