jQuery AJAX desde PHP con jsonwrapper

Codigo del webservice:
prueba1.php

<?php
   $receive=file_get_contents('php://input');
   $p = json_decode($receive);

   $pp[0]["prueba0"] = $p["parametro1"];
   $pp[0]["prueba1"] = "abc";
   $pp[0]["ss"] = "zzz";
   $p = json_encode($pp);

   echo $p;
?>

Codigo JS:

function invocarAjax(url_ws, param_ws, funcion_ws, async_ws)
{
if(async_ws===undefined)
  async_ws = false;

jQuery.ajax({
  type: "POST",
  timeout: 5000,
  url: url_ws + "?" + "random=" + Math.floor(Math.random()*9999999999),
  data: param_ws,
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  cache: false,
  async: async_ws,
  success: function(response) {
   window[funcion_ws](response, null);
  },
  error: function(xhr, ajaxOptions, thrownError) {
   window[funcion_ws](null, xhr.responseText );
  }
});
}
function getJSON(data_obj)
{
if (data_obj.d)
    data_ok = data_obj.d;
else
   data_ok = data_obj;
   evalJson = eval("var varJSON = " + data_ok + ";");
return varJSON;
}

Código que invoca al webservice:

<script>
$(document).ready(function() {
$("#setear").click(function() {
  url_ws = "prueba1.php";
  param_ws = '{"parametro1": "5555", "enviar_todos": "S"}';

  invocarAjax(url_ws, param_ws, "callbackConfigEmails", true);
});
});
function callbackConfigEmails(v, err)
{
if (err == null)
{
   if (v[0].prueba1 != "")
  {
   alert("prueba0: " + v[0].prueba0);
   alert("prueba1: " + v[0].prueba1);
  }

} else
  alert("ERROR: " + err);
}
</script>

OJO!!!!!
El codigo json_decode de jsonwrapper NO funciona, en su lugar, utilizar este:

function json_decode($json)
{
$comment = false;
$out = '$x=';
for ($i=0; $i<strlen($json); $i++)
{
  if (!$comment)
  {
   if (($json[$i] == '{') || ($json[$i] == '['))
    $out .= ' array(';
   else if (($json[$i] == '}') || ($json[$i] == ']'))
    $out .= ')';
   else if ($json[$i] == ':')
    $out .= '=>';
   else
    $out .= $json[$i];
  } else
   $out .= $json[$i];
   if ($json[$i] == '"' && $json[($i-1)]!="\\")
    $comment = !$comment;
}

eval($out . ';');

return $x;
}

Retornar un valor desde una funcion con llamado a jQuery.Ajax

WebService y JSON con jQuery, con Visual Studio 2008 que corre en Visual Studio 2005

1. Crear un web service con visual studio 2008

Instalar ASPAJAXExtSetup.msi

Esto deja una dll en la siguiente ruta:

Esa dll es la que permite hacer el "using System.Web.Extensions", y es donde esta "System.Web.Script.Services.ScriptService" (lo que permite llamar al webservice desde un javascript con ajax, por ej)

Plugin para autocompletar en jQuery y solucion para z-index en IE6

http://docs.jquery.com/Plugins/autocomplete

Ejemplo de jquery autocomplete:
http://blog.zeion.net/2011/12/15/ejemplo-practico-de-autocompletar-con-jquery/

Usar el siguiente código en jquery.autocomplete.js para solucionar el problema con el z-index en IE6
Adicionalmente es necesario colocar un iframe debajo del campo donde se aplique el autocomplete para que funcione... de esta forma:

<input type="text" id="txtPrueba" size="20" />
<IFRAME id="cover" style="DISPLAY: none; LEFT: 0px; POSITION: absolute; TOP: 0px" src="javascript:false;" frameBorder="0" scrolling="no"></IFRAME>
