Hi,

I am trying to get to know AJAX but when I browse to the following index.html file on my Ubuntu LAMP server I get the following error message:

Permission denied to call method XMLHttpRequest.open

found via the Firefox JavaScript Console (and a much less informative Permission Denied message in Internet Explorer).

If you can help it would be greatly appreciated.

Code for index.html:

<html>
<head>
<title>Ajax at work</title>
<script language = "javascript">
var XMLHttpRequestObject = false;
if (window.XMLHttpRequest) {
XMLHttpRequestObject = new XMLHttpRequest();
} else if (window.ActiveXObject) {
XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP");
}
function getData(dataSource, divID)
{
if(XMLHttpRequestObject) {
var obj = document.getElementById(divID);
XMLHttpRequestObject.open("GET", dataSource);
XMLHttpRequestObject.onreadystatechange = function()
{
if (XMLHttpRequestObject.readyState == 4 &&
XMLHttpRequestObject.status == 200) {
obj.innerHTML = XMLHttpRequestObject.responseText;
}
}
XMLHttpRequestObject.send(null);
}
}
</script>
</head>
<body>
<H1>Fetching data with Ajax</H1>
<form>
<input type = "button" value = "Display Message"
onclick = "getData('http://localhost/ch02/data.txt',
'targetDiv')">
</form>
<div id="targetDiv">
<p>The fetched data will go here.</p>
</div>
</body>
</html>


I have not supplied the contents of data.txt i.e. it's just a line of text to test things out.

Thanks again in advance,
R.
