AJAX IE error

[yonni]

I have an ajax code that works fine in firefox, but not in IE. The bit of code we're interested in is:
<a href=# onclick='view("ajaxpage","news.html","newsButton","news");'><img src="News2.gif" border="0" style="position: absolute; top: 118px; left: 605px;" name="newsButton"></a>
then...
<script type=text/javascript language=javascript>
var homePage="true";
var sessionsPage="false";
var montessoriPage="false";
var contactPage="false";
var ajaxPage="false";
var page;
function view(page,url,button,buttonimg) {
document.getElementById(page).style.visibility='visible';
if(page=="") {
return
}
ajaxPage="false";

if(page=="ajaxpage") {
ajaxPage="true";
document[button].src=buttonimg+'.gif';
document.getElementById("ajaxpage").style.visibility="visible";
http=getHTTPObject();
if(http==null) {
document.getElementById('ajaxpage').innerHTML="<img src='error.jpg'>Your browser does not support the scripts for this page";
return;
}
http.open("POST",url,true);
http.onreadystatechange = loadDocument;
http.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
http.send("firefoxfix=true");
} else {
document.getElementById("ajaxpage").style.visibility="hidden";
document["newsButton"].src='news2.gif';
}
}

function loadDocument() {
if (http.readyState==4 || http.readyState=="complete") {
document.getElementById("ajaxpage").innerHTML = http.responseText
}
}

function getHTTPObject() {
var objXMLHttp=null
if (window.XMLHttpRequest) {
objXMLHttp=new XMLHttpRequest()
}
else if (window.ActiveXObject) {
objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP")
}
return objXMLHttp
}
</script>
This works lovely until the line:
http.open("POST",url,true);
Where IE enjoys to spit me an error message: "Access denied". The only explanation I can find for this is that I've requested it to open a file it isn't allowed to, which I havent. I am currently still testing this on my home PC (not a server yet), and the file I've requested it to open is (as you can see) in the same folder as this file.
I really don't get why this doesn't work, so I thought I'd let you guys have a look, cause having an extra pair of eyes that hasn't coded this from scratch always helps. Thanks in advance :)

I cant say i see anything wrong with it.
but i can say that I.E. doesnt like to let you POST. it is a security thing.
I'm asumming you have I.E. right? try saving the file as a .hta file, i'll bet it works then. but of course that is not a solution to your problem. it is only a means to prove that the code works for i.e. when higer privliges are granted. (.hta is a hyper text application).

You can post in AJAX just fine in IE. Below is some example code. Are you sure the page you are requesting is on the same domain?


function getReqObjPost(url,params,func)
{
if (window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
if(new ActiveXObject("Microsoft.XMLHTTP"))
{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
else
{
xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
}
}

xmlhttp.onreadystatechange=function()
{
if(xmlhttp.readyState==4)
{
if(xmlhttp.status==200)
{
var req_str=xmlhttp.responseText;
var req=xmlhttp.responseXML;
eval(func);
}
else
{
noData(xmlhttp.status);
}
}
}
var now=new Date();
params=params + "&c_date"+now.getSeconds()+"=" + now;
xmlhttp.open("POST",url,true);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
xmlhttp.send(params);
}


Call like this:

getReqObjPost("somepage.asp","x=y&c=b&red=pretty","someCallBackFunction(req,req_str)")

It is possible that IE prevents you from using scripts to open files on your computer; also products like defender and antispy may be overprotecting you. If it works in firefox, and you don't get a null object error in IE, then the code is OK. Look to your security settings.

As a .hta file I get the same error :(
