I am using firefox as my browser. When I run this page it will go out and get my xml but doesnt do anything else. If I put an alert inside my anonymous function it never gets ran. Neither does anything else in the function, including my showData function. Anyone know why this is happening? thanx in advance for the help!

var XMLHttpRequestObject = false;
if(window.XMLHttpRequest){
XMLHttpRequestObject = new XMLHttpRequest();
}
else if(window.ActiveXObject){
XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP");
}

function showData(xmldoc){
var docElement, usernameNode, usernameidNode, displayText;

docElement = xmldoc.documentElement;
usernameNode = docElement.firstChild;
usernameidNode = usernameNode.nextSibling;

displayText = usernameNode.firstChild.nodeValue + ' ' + usernameidNode.firstChild.nodeValue;

var target = document.getElementById('usernameoutput');
target.innerHTML = displayText;

}
function getUsernames(){

var searchvalue = document.getElementById("uname").value;
var datasource = "search_profiles_now.php?searchvalue=" + searchvalue;

if(XMLHttpRequestObject){
document.getElementById('loadimage').style.display = "inline";
XMLHttpRequestObject.open("GET", datasource);

XMLHttpRequestObject.onreadystatechange = function()
{
if(XMLHttpRequestObject.readyState == 4){
var xmldoc = XMLHttpRequestObject.responseXML;
showData(xmldoc);
}
}
document.getElementById('loadimage').style.display = "none";
XMLHttpRequestObject.send(null);
}
}

I added true to my .readystatechange and this got me into my anonymous function.

XMLHttpRequestObject.open("GET", datasource, true);


However now its saying xmldoc had no properties. hmmmm anyone know whats stopping the response from being put into xmldoc? The error is coming from line 12 which is in my showData function:

function showData(xmldocument){
var docElement, usernameNode, usernameidNode, displayText;

docElement = xmldocument.documentElement;
usernameNode = docElement.firstChild;
usernameidNode = usernameNode.nextSibling;

displayText = usernameNode.firstChild.nodeValue + ' ' + usernameidNode.firstChild.nodeValue;

var target = document.getElementById('usernameoutput');
target.innerHTML = displayText;

}

No one has responded to my post and I have been trying to get this code running. My post maybe confusing so here is my full code as it stands. The error I am getting is xmldoc has no properties

My code:

var XMLHttpRequestObject = false;
if(window.XMLHttpRequest){
XMLHttpRequestObject = new XMLHttpRequest();
}
else if(window.ActiveXObject){
XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP");
}

function showData(xmldoc){
var docElement, usernameNode, usernameidNode, displayText;

docElement = xmldoc.documentElement;
usernameNode = docElement.firstChild;
usernameidNode = usernameNode.nextSibling;

displayText = usernameNode.firstChild.nodeValue + ' ' + usernameidNode.firstChild.nodeValue;

var target = document.getElementById('usernameoutput');
target.innerHTML = displayText;

}
function getUsernames(){

var searchvalue = document.getElementById("uname").value;
var datasource = "search_profiles_now.php?searchvalue=" + searchvalue;

if(XMLHttpRequestObject){
document.getElementById('loadimage').style.display = "inline";
XMLHttpRequestObject.open("GET", datasource, true);

XMLHttpRequestObject.onreadystatechange = function()
{
if(XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200){
var xmldocument = XMLHttpRequestObject.responseXML;
showData(xmldocument);
document.getElementById('loadimage').style.display = "none";
}
}
XMLHttpRequestObject.send(null);
}
}

I am running firefox and have fire bug. My javascript is getting my xml data back to the browser but im still getting xmldoc has no properties. Any ideas?!

Finally fixed my own issue. I was missing header("Content-type: text/xml"); in my xml document so javascript didnt know what it was looking at.

Glad you got it all worked out. Sorry no one was able to help. I think it was just a combination of AJAX being new to a lot of people and that weekends aren't as bus around here. Fortunately you were able to get the issue resolved on your own.
