am using the following code where it is giving me an "Undefined" error
in Firefox while it is running well on IE, the line which cuz the error is "XHR.open("GET",url,true);", any idea ????

var XHR;
function BuildXHR(url)
{
    if (window.XMLHttpRequest)
    {
    XHR = new XMLHttpRequest();
    }
    else if (window.ActiveXObject)
    {
    XHR = new ActiveXObject("Microsoft.XMLHTTP");
    }

    if (XHR == null)
    {
    alert ("Browser does not support HTTP Request");
        return;
    }

    XHR.onreadystatechange = StateChanged;
    XHR.open("GET",url,true);
    XHR.send(null);
}

What is it saying is undefined?

Is there more code? Where is the function StateChanged defined?






Regards,
Rich

i found the solution, there is something about "cross domain' call, i was calling a page in another domain where
Firefox it seems prevent doing that, but i found the the following code which let me do it but an alert will appear:

try
{
   netscape.security.PrivilegeManager.enablePrivilege ("UniversalBrowserRead");
}
catch(e)
{
   alert("Permission UniversalBrowserRead denied.");
}
