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()
