Vermeidung doppelter Formularseitenübertragungen

Internet 2021-08-14 20:39:10 10 8,098

Auf vielen Websites, auf denen Formulare mit Daten übermittelt werden, kommt es leicht zu der Situation, dass der Benutzer über die Zurück-Schaltfläche des Browsers zu der Seite zurückkehrt, bevor das Formular übermittelt wurde, und dann das Formular mehrfach übermittelt.

Um die Übermittlung doppelter Daten zu vermeiden, können Sie mit JavaScript einen einfachen Code in den Head-Tag einer Webseite einfügen, um die Aufzeichnung des Verlaufs durch den Browser zu deaktivieren.

JavaScript:window.history.forward(1);

Dadurch wird der Browser daran gehindert, den Verlauf der vorherigen Seite zu speichern, so dass die Nutzer keine doppelten Daten eingeben können.

    Having read this I thought it was extremely informative. I appreciate you spending some time and effort to put this content together. I once again find myself spending way too much time both reading and posting comments. But so what, it was still worthwhile!

    Hi there would you mind stating which blog platform you're working with? I'm planning to start my own blog in the near future but I'm having a difficult time selecting between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your layout seems different then most blogs and I'm looking for something unique. P.S My apologies for getting off-topic but I had to ask!

    Do you have a spam problem on this blog; I also am a blogger, and I was wondering your situation; many of us have developed some nice methods and we are looking to swap techniques with other folks, why not shoot me an e-mail if interested.
