form serialize javascript (no framework)

Question

Wondering is there a function in javascript without jquery or any framework that allows me to serialize the form and access the serialized version?

Answer 1

Here is pure JavaScript approach:

var form = document.querySelector('form');
var data = new FormData(form);

  var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
       console.log(this.responseText);
    }
  };
  xhttp.open("POST", "", true);
  xhttp.send(data);
}
