POST form data using JavaScript's Fetch API

Form data can be sent via JavaScript's Fetch API by converting the form element into a FormData object or a URL-encoded string and specifying this as the body of the fetch request.

One important detail that you didn't mention is that each imput has to have a name attribute (with a value) to be included in the formData element, otherwise it skips it

thanks. i was getting frustated with the content type, when i fetch the FormData to a servlet it came out empty, just adding URLSearshParam made it work.

form.addEventListener('submit', function(e) {

[nikolozdvali]

I have all input data saved in local storage and want to send it. Is there any way to send formdata from there
