How to get data from FormData on server side?

Question

AJAX

Good day, through ajax data goes to the server in the form FormData, that is, when reading the form on the server, [object FormData] is returned.
Actually, the question itself is: how to get data from this form on the server?

Answer 1

Damn it! It's hard for you! You can add only strings with strings, numbers only with numbers. But different objects are not allowed! FormData is not a string that contains a URL, it's an object!
request.send(form);
And that's it! Understand?
Output through alert try and you will understand what is wrong!
The rest of the data is of the type data = add something there by analogy through .append.
And one more thing: the form can be created from an HTML form that you already have on the page!

form = new FormData( document.getElementsByTagName("form")[0] );

Answer 2

request.send("data"+form);

oh, someone else needs to learn js in order not to write this, although here, of course, it’s not about understanding the language, but about common sense. Do you understand what you did here?
