newbie needs help with AJAX

abhisek · Jan 25, 2008

Hello!
I don't know whether to post it over here since it's a javascript
group. But i am having trouble with aJax
I just started learning ajax with ajax for dummies. Very often i am
getting the same error message in firebug "uncaught exception:
Permission denied to call method XMLHttpRequest.open". What's
surprising is the same page that works with firefox is not working
with IE even if it has an ActiveXObject("Microsoft.XMLHTTP") object.
Help is much appreciated.
Regards
Abhisek

Where else would you post it? ok.
Not a good book. Please suggest me a good book.
Show the code that causes that error.

Here it is:
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, false);

XMLHttpRequestObject.onreadystatechange = function()

{

if(XMLHttpRequestObject.readyState==1){obj.innerHTML='fetching...';}

if (XMLHttpRequestObject.readyState == 4 &&

XMLHttpRequestObject.status == 200) {

obj.innerHTML = XMLHttpRequestObject.responseText;

}

}

XMLHttpRequestObject.send(null);

}

}

Nothing about IE surprises me anymore. Show the code.

LOLZ!

Oops! This are all the codes:
<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, false);

XMLHttpRequestObject.onreadystatechange = function()

{

if(XMLHttpRequestObject.readyState==1){obj.innerHTML='fetching...';}

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 = "showData('http://localhost/ajax/data.txt', 'targetDiv')">

</form>

<div id='targetDiv'>Nothing fetched</div>

Usenet isnt the only resource in the world, ya know..

Not a good book.

Your opinion - one of many.

Whats with the attitude here? The guy is being polite. If you'd rather
not respond to people, then don't.

Your function is named getData, yet you are trying to call showData

Ok error corrected. But still the same error:
uncaught exception:
Permission denied to call method XMLHttpRequest.open

do you call a file from same domain ?

It seems that no : "Permission denied"

the cros-domain is forbidden.

No. called it from the same domain.

W3Schools does not qualify as reference material.

A far better resource about the technology is
