Preventing the Confirmation Form Resubmission Dialog

When refreshing a page after submitting a form, a confirmation dialog may appear, warning against resubmitting information. This can be an inconvenience, especially for users performing repeated form submissions. This article explores a method to prevent the appearance of this dialog.

One effective approach is to use JavaScript in the reloaded page's HTML. By implementing the following code:

if ( window.history.replaceState ) {
  window.history.replaceState( null, null, window.location.href );
}

this code updates the browser history, preventing the need for a resubmission confirmation. This method works by clearing the form information after the initial submission, eliminating the data that triggers the resubmission warning. As a result, the page can be refreshed without encountering the confirmation dialog.
