If you are at the stage where you are finished with the post data and simply want to view the page again afresh  you could just use a window location and even maybe append a random string as a query paramater to guarantee a new version of the page

The other solutions with window location didn t work for me since they didn t make it refresh at all  so what I did was that I used an empty form to pass new and empty postdata to the same page  This is a way to do that based on this answer   function refreshAndClearPost         var form   document createElement  form        form method    POST       form action   location href      form style display    none        document body appendChild form       form submit         since the form is empty  it will pass empty postdata     document body removeChild form

This worked   lt button onclick  window location href window location href  return false   gt Continue lt  button gt    The reason it didn t work without the return false  is that previously it treated that as a form submit button  With an explicit return false on it  it doesn t do the form submit and just does the reload of the same page that was a result of a previous POST to that page

Just changing window location in JavaScript is dangerous because the user could still hit the back button and resubmit the post  which could have unexpected results  such as a duplicate purchase   PRG is a much better solution  Use the Post Redirect Get  PRG  pattern     To avoid this problem  many web applications use the PRG pattern     instead of returning an HTML page directly  the POST operation returns a redirection command  using the HTTP 303 response code  sometimes 302  together with the HTTP  Location  response header   instructing the browser to load a different page using an HTTP GET request  The result page can then safely be bookmarked or reloaded without unexpected side effects

You can t refresh without the warning  refresh instructs the browser to repeat the last action  It is up to the browser to choose whether to warn the user if repeating the last action involves resubmitting data   You could re-navigate to the same page with a fresh session by doing   window location   window location href

I ve written a function that will reload the page without post submission and it will work with hashes  too    I do this by adding   modifying a GET parameter in the URL called reload by updating its value with the current timestamp in ms    var reload   function          var regex   new RegExp       amp   reload   amp       amp           var query   window location href split      0  replace regex    1   replace   amp              window location href            window location href indexOf       lt  0         query    query slice -1             amp                     reload     new Date   getTime     window location hash       Keep in mind  if you want to trigger this function in a href attribute  implement it this way  href  javascript reload   void 0   to make it work  successfully   The downside of my solution is it will change the URL  so this  reload  is not a real reload  instead it s a load with a different query  Still  it could fit your needs like it does for me
