var container = "header";
var formId = "id-contactform";
var url_post = "/contact/form/"

function callBackLoad(){
  formRender(this.responseText);

function callBackSubmit(event) {
  event.preventDefault();
  formPost(event)

function formPost(event){
  var formPost = new XMLHttpRequest();
  var formData = new FormData(ctctForm );
  x = formPost.open('POST',url_post, false); // Não assincrono.
  y = formPost.send(formData);
  console.log('responseText:=>>'+formPost.responseText);
  console.log('responseXML:=>>'+formPost.responseXML);
  console.log('responseSTATUS:=>>'+formPost.status);
