Peguei o codigo:
<script language="javascript">
function pesquisar_dados( valor )
{
  http.open("GET", "[color="#FF0000"]consultar.php[/color]?id=" + valor, true);
  http.onreadystatechange = handleHttpResponse;
  http.send(null);
}
function handleHttpResponse()
{
  campo_select = document.forms[0].subcategoria;
  if (http.readyState == 4) {
	campo_select.options.length = 0;
	results = http.responseText.split(",");
	for( i = 0; i < results.length; i++ )
	{
	  string = results[i].split( "|" );
	  campo_select.options[i] = new Option( string[0], string[1] );
	}
  }
}
function getHTTPObject() {
  var xmlhttp;
  /*@cc_on
  @if (@_jscript_version >= 5)
	try {
	  xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
	  try {
		xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
	  } catch (e) {
		xmlhttp = false;
	  }
	}
  @else
  xmlhttp = false;
  @end @*/
  if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
	try {
	  xmlhttp = new XMLHttpRequest();
	} catch (e) {
	  xmlhttp = false;
	}
  }
  return xmlhttp;
}
var http = getHTTPObject();
</script>a pagina consultar.php vai me mostrar com o echo 1 ou 2
Entao queria por um if la no ajax para que se for 1 mostra o alert e se for 2 nao mostra nada/nao faz nada...
acho que seria la no function handleHttpResponse()
