Please show an example of a POST request?

Question

JavaScript

Hello, can you show an example of sending a POST request.
In fact, I need to transfer a large piece of text to PHP functions, and that's it.
Important: the example is needed WITHOUT jQuery.

Answer 1

It is assumed that your text is in the form field

var formElement = document.querySelector("form");
var request = new XMLHttpRequest();
request.open("POST", "submitform.php");
request.send(new FormData(formElement));

or add it yourself

var big_text = "И таак сойдееет!";
var formElement = document.querySelector("form");
var formData = new FormData(formElement);
var request = new XMLHttpRequest();
request.open("POST", "submitform.php");
formData.append("big_text", big_text);
request.send(formData);
