Convert javascript to use POST instead of GET

[Snowl]

I found a really cool script (link) except when I try to use it, it uses GET instead of POST. I don't want to use GET for what i'm using it for and would much rather use POST.

Here is the part of the script (I think) that makes it use POST.

<!--
//script by [url="http://www.yvoschaap.com//XMLHttpRequest"]http://www.yvoschaap.com

//XMLHttpRequest[/url] class function
function datosServidor() {
};
datosServidor.prototype.iniciar = function() {
 try {
  // Mozilla / Safari
  this._xh = new XMLHttpRequest();
 } catch (e) {
  // Explorer
  var _ieModelos = new Array(
  'MSXML2.XMLHTTP.5.0',
  'MSXML2.XMLHTTP.4.0',
  'MSXML2.XMLHTTP.3.0',
  'MSXML2.XMLHTTP',
  'Microsoft.XMLHTTP'
  );
  var success = false;
  for (var i=0;i < _ieModelos.length && !success; i++) {
   try {
    this._xh = new ActiveXObject(_ieModelos[i]);
    success = true;
   } catch (e) {
   }
  }
  if ( !success ) {
   return false;
  }
  return true;
 }
}

datosServidor.prototype.ocupado = function() {
 estadoActual = this._xh.readyState;
 return (estadoActual && (estadoActual < 4));
}

datosServidor.prototype.procesa = function() {
 if (this._xh.readyState == 4 && this._xh.status == 200) {
  this.procesado = true;
 }
}

datosServidor.prototype.enviar = function(urlget,datos) {
 if (!this._xh) {
  this.iniciar();
 }
 if (!this.ocupado()) {
  this._xh.open("GET",urlget,falsethis.this._xh.send(datos);
  if (this._xh.readyState == 4 && this._xh.status == 200) {
   return this._xh.responseText;
  }

 }
 return false;
}


var urlBase = "/microposts/";
var formVars = "";
var changing = false;


function fieldEnter(campo,evt,idfld) {

Thanks for your help :D

Why is it in Spanish?

It looks like it uses functions that you haven't included.

[Snowl]

Updated with the full script. And it's not mine.

[lnmnky]

So it does an ajax request using the Get method.

You can change that to do an ajax via a Post if you wish. Ajax doesn't care, but the response page does / might.

What is it that you actually want to do? Just change the method? That's one line of script.

document.forms[0].method = "post";

datosServidor.prototype.enviar = function(urlget,datos) {
 if (!this._xh) {
 this.iniciar();
 }
 if (!this.ocupado()) {
 this._xh.open("GET",urlget,false= THIS, i think if you change to "post" it will always do a post, the code does not seem to catter to post/get it's hardcoded for get only
 this._xh.send(datos);
 if (this._xh.readyState == 4 && this._xh.status == 200) {
 return this._xh.responseText;
 }

 }
 return false;
}
