Estoy recien incursionando en el mundo de AJAX guiado por un manual.
Probando un ejercicio no me ha dado la respuesta esperada
Este es el codigo
Código PHP:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional //EN" "http://www.w3.org/TR/xhtml1-transitional.dtd">
<html>
<head>
<title>Ejemplo02 AJAX</title>
<script type="text/javascript">
var net = new Object();
net.READY_STATE_UNINITIALIZED = 0;
net.READY_STATE_LOADING = 1;
net.READY_STATE_LOADED = 2;
net.READY_STATE_INTERACTIVE = 3;
net.READY_STATE_COMPLETE = 4;
net.CargadorContenidos = function(url, funcion, funcionError) {
this.url = url;
this.req = null;
this.onload = funcion;
this.onerror = (funcionError) ? funcionError : this.defaultError;
this.cargaContenidoXML(url);
}
net.CargadorContenidos.prototype = {
cargaContenidoXML:function(url) {
if (window.XMLHttpRequest) {
this.req = new XMLHttpRequest();
}
else if (window.ActiveXObject) {
this.req = new ActiveXObject("Microsoft.XMLHTTP");
}
if (this.req) {
try {
var loader = this;
this.req.onreadystatechange = function () {
loader.onReadyState.call(loader);
}
this.req.open('GET', url, true);
this.req.send(null);
} catch(err) {
this.onerror.call(this);
}
}
},
onReadyState:function () {
var req = this.req;
var ready = this.readyState;
if (ready == net.READY_STATE_COMPLETE) {
var httpStatus = req.status;
if (httpStatus == 200 || httpStatus == 0) {
this.onload.call(this);
}
else {
this.onerror.call(this);
}
}
},
defaultError:function () {
alert ("Se ha producido un error al obtener los datos: "
+ "\n\n readyState: " + this.req.readyState
+ "\n Status: " + this.req.status
+ "\n headers: " + this.req.getAllResponseHeaders());
}
}
function mostrarContenido() {
alert(this.req.responseText);
}
function cargaContenidos() {
var cargador = new net.CargadorContenidos("http://localhost/ajax/holamundo.txt", mostrarContenido);
}
window.onload = cargaContenidos;
</script>
</head>
<body>
</body>
</html>
En la funcion
Código PHP:
onReadyState:function () {
var req = this.req;
var ready = this.readyState;
if (ready == net.READY_STATE_COMPLETE) {
var httpStatus = req.status;
if (httpStatus == 200 || httpStatus == 0) {
this.onload.call(this);
}
else {
this.onerror.call(this);
}
}
},
Me podrian ayudar a resolverlo?
Mil Gracias de antemano
Un Cordial Saludo.
