Pass Parameters To XMLHttpRequest Object

Question

How can I pass parameters to the XMLHttpRequest Object?

function setGUID(aGUID) {

    var xhReq = new XMLHttpRequest();

Answer 1

This way works for me.

var data = new FormData();
data.append('parameter_1', 'value parameter 1');
data.append('parameter_2', 'value parameter 2');
...

var xhr = new XMLHttpRequest();
xhr.open('POST', 'URL', true);
xhr.onload = function () {
    console.log(this.responseText);
};
xhr.send(data);
