AJAX and JavaScript

Question

Im having an issue with the request below, for some reason I can seem to get the XML to display?

I've checked the URL and it displays fine, so im wondering whats going on?! Could anyone give me a hand? There should be something in the ResponseText not "NULL".

var url = "https://services.lexel.co.uk/paf/";

loadXMLDoc(url)

function loadXMLDoc(url)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET",url,false);
xmlhttp.send(null);
alert(xmlhttp.responseText);
}

Where'd you get this sample? It's wrong.

You cannot use AJAX to send a request to a different domain.

How can I use the XML post to get data from a different domain?

SLaks Over a year ago

You need to write a server-side script on your domain that forwards the request to the other domain.

You can't. It's a XSS exploit possibility if it could. As SLaks said, use a server-side script.

What server-side language do you use?

@Josh the 3rd parameter of Send was "false" which means "Don't be asynchronous; block until we're done loading" [In other words, what he did is valid]

Here is some literature on cross-domain ajax: http://www.xul.fr/ajax/xdomainrequest.php Cross domain request (XDR) http://msdn.microsoft.com/en-us/library/dd573303(v=vs.85).aspx
