Как избежать дублирования отправки страниц с формами

Интернет 2021-08-14 20:39:10 6 9,548

На многих сайтах, где формы отправляются с данными, легко столкнуться с ситуацией, когда пользователь возвращается на страницу, предшествующую отправке формы, с помощью кнопки “Назад” браузера, а затем отправляет форму несколько раз.

Чтобы избежать отправки дубликатов данных, вы можете использовать JavaScript для добавления простого фрагмента кода в тег head веб-страницы, чтобы запретить браузеру записывать историю.

JavaScript:window.history.forward(1);

Это запретит браузеру записывать историю предыдущей страницы, что предотвратит отправку пользователями дублирующихся данных.

    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.
