Show notice without 'refresh' when JavaScirpt is disabled.

Refreshing page without JavaScript has issues:
- Relative URL is not permitted when refreshing.
- After turning on JavaScript, user needs to force reloading the page.

By showing notice without changing the URL, we can solve those issues.
