Cual es el error? Hola a todos tengo el siguiente codigo:
function createRequest(){
var httpRequest = null;
if(window.XMLHttpRequest){//mozilla, safari,...
httpRequest = new XMLHttpRequest();
if(httpRequest.overrideMineType){
httpRequest.overriderMineType('text/xml');
}
} else if(window.ActiveXObject){ //IE
try{
httpRequest = new ActiveXObject("Msxml2.XMLHTTP");
}catch(e) {
try{
httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
return httpRequest;
}
function CargarCombo(objetoCombo,accion){
clearChildNode(objetoCombo);
http = createRequest();
http.open('POST', accion, false);
http.onreadystatechange = handleHttpGet;
http.send(null);
var select = document.getElementById(objetoCombo);
var items = http.responseXML.getElementsByTagName("Dato");
alert();
for (var i = 0; i < items.length; i++){
valueCombo=items.getElemenstByTagName('valor').ite m(0);
captionCombo=items.getElemenstByTagName('nombre'). item(0);
agregarDatosCombo(select, valueCombo, document.createTextNode(captionCombo));
}
}
function handleHttpGet(){
if (http.readyState == 1){
if(document.getElementById("wait")){
document.getElementById("wait").innerHTML ="Cargando Datos...";
document.getElementById("wait").style.visibility=' visible';
}
}
if (http.readyState == 4) {
if (http.status == 200){
}
if(document.getElementById("wait")){
document.getElementById("wait").style.visibility=' hidden';
}
}
}
/************************************************** ************************************************** ********************/
function agregarDatosCombo(select, valueCombo, captionCombo){
var opt;
http = createRequest();
opt = document.createElement("option");
opt.value = valueCombo;
opt.appendChild(captionCombo);
select.appendChild(opt);
}
function clearChildNode(elemID){
http = createRequest();
var elem = document.getElementById(elemID);
while (elem.childNodes.length > 0) {
elem.removeChild(elem.firstChild);
}
var opt;
opt = document.createElement("option");
opt.value = -1;
opt.appendChild(document.createTextNode('Seleccion e'));
elem.appendChild(opt);
}
pero me sale error, dice q http no es una propiedad
porq?
