How to change the default redirect after click on save button when you add data?

Everyone know, when add data by using grocery-crud, at end of the page there is a button named save to save the data in database.

This save button when clicked, save the data, then redirect to the data list page.

Now I'm use $crud->unset_list() method to unset the data list page.

Thus, when clicked on save button redirect to blank page, and that was the data list page.

My question:
How to redirect to a specific page as I want after clicked on save button, instead of redirect to data list page as it was

• An example of data list page

These people seem to be having success using a JavaScript workaround:

Update:

adding code for answer preservation...

For Insert:

$crud->set_lang_string('insert_success_message',
         'Your data has been successfully stored into the database.<br/>Please wait while you are redirecting to the list page.
         <script type="text/javascript">
          window.location = "'.site_url(strtolower(__CLASS__).'/'.strtolower(__FUNCTION__)).'";
         </script>
         <div style="display:none">
         '
   );

For Update:

$crud->set_lang_string('update_success_message',
     'Your data has been successfully stored into the database.<br/>Please wait while you are redirecting to the list page.
     <script type="text/javascript">
      window.location = "'.site_url(strtolower(__CLASS__).'/'.strtolower(__FUNCTION__)).'";
     </script>
     <div style="display:none">
);
