I've still got the problem.
I can't find why.

Have you tried if (req.status && req.status == 200)?

Replace:
if (req.status == 200)

to:
if (req.status == 200)||(req.stat us == 0))

If it helps, ask my why (and you owe me a bottle of Bordeaux of a good
year :-D

`req.status' will never be 0 (and will never be converted to it implicitly,
see ECMAScript Ed. 3, sections 11.9.1 and 11.9.1), there is no such status
code in HTTP and the Microsoft IXMLHttpRequest interface reference, from
which Gecko's XMLHttpRequest derives, does not suggest the property could
hold this value or a value convertible to 0 ever. Therefore, the approach
Ian suggested is, unfortunately unsurprisingly, more reasonable than this.

I'm wondering what do you have to say about Windows issues if you
stated several times that you are under Linux? Unless you have Windows
installed as well ? Are we cheating? ;-)

FYI: using IXMLHTTPRequest for local (file:\\) files under Windows / IE
6.x returns status 0 is success. So if the said bookmarklet used both
for local and remote files, it may cause a hard to catch erratic
behavior, because for local files status will never be 200 - despite
the file itself will be perfectly loaded.
Also as you cannot set Content-Type for file:\\ (at least for Windows),
XML files loaded from harddrive do no trig XML parser (as it reacts on
Content-Type only, not on file extension), so for your local .xml files
responseXML is always "", only responseText is OK. That is another
erratic behavior which may draw you crazy because the same file may
parse just fine from server and "disappear" as soon as saved as local
file.

ECMAScript Ed. 3 doesn't know about it which is not a suprise of any
kind.

P.S. It is not the fact that it is the OP's problem, but something to
start with. Another explanation can be in Firefox' bookmarlet security
mechanics. We shall move on it if the above suggestion will fail.

Re: Problem with XmlHttpRequest (0x80040111 / nsIXMLHttpReque st.status) on several configurations

Thanks for your replies but no one of your suggestions works...

I'm 2 days at my parent's office and they have several PCs with windows
and Firefox 1.5.
It's almost strange because the application works on the server but
doesn't on 2 'office' PCs.

If I print the readyState like this :
-------------------------------------------
try {
document.getEle mentById("conte nt").innerHTM L += req.readyState +
' ';
if (req.readyState == 4) {
if (req.status == 200) {
responseXmlHand ler(req.respons eXML);
} else {
alert("HTTP error: "+req.statu s);
}
}
} catch(e) {
alert("Exceptio n : " + e);
}
-------------------------------------------
I've got :
- if it's working : 1 1 2 3 3 4
- if not : 1 1

And (on configuration wich it doesn't working), If I refresh the page,
I caught the exception 0x80040111 (NS_ERROR_NOT_A VAILABLE)
[nsIXMLHttpReque st.status]....

I will try to debug this piece of code during the day. If I find a
solution, I'll come back to you.

By the way, this address book project is now on SourceForge :

Gcontact

http://sourceforge.net/projects/gcontact

Download Gcontact for free. GContact is a Web based address book in Ajax/PHP : multi-user, multi-contacts (email,phone,icq,msn,...) & multi-address for each person, birthday reminder by email, mailing-list management, Excel export, ...

But, for now, screens are only available in French.

The list line sounds really close to
<http://ajaxtoolbox.com/forum/viewtopic.php?p =102&sid=f2be51 bc80038174198e5 f52e7d91554>

Does it help anyhow if you do not use any req properties in
else-brunch?

Re: Problem with XmlHttpRequest (0x80040111 / nsIXMLHttpReque st.status) on several configurations

Wait !
Now, some HttpRequests are working !
But not on all functions on my application...
It's strange but now, I can look for differences between functions wich
are working and thoses which don't !
I think I will soon debug that problem !

Cool.

Re: Problem with XmlHttpRequest (0x80040111 / nsIXMLHttpReque st.status) on several configurations

I've found the problem !!!
It's because, when I don't have param to send, I'm sending some request
in this way : "req.send(null) ;"
And this don't work on some configurations !!!

If I use this : "req.send(' ');" (with space instead of null)
It's always work !!!!

What a stupid bug !

It is not really a bug AFAIK, but a difference between IXMLHTTPRequest
(Microsoft) and XMLHttpRequest (others). At least all MSDN samples seem
to go with "" and all Mozilla samples with null. Never studied it
profoundly though.

Re: Problem with XmlHttpRequest (0x80040111 / nsIXMLHttpReque st.status) on several configurations

Can someone tell me why Firefox is not working with AJax and ONLY for
one of my scripts.

the error is

Error: [Exception... "Component returned failure
code: 0x80040111 (NS_ERROR_NOT_A VAILABLE) [nsIXMLHttpReque st.status]"
nsresult: "0x80040111 (NS_ERROR_NOT_A VAILABLE)" location: "JS frame ::
http://www.stepnstomp.co.uk/java/ajax.js :: alertContents :: line 41"
data: no]
Source File: /java/ajax.js
Line: 41

the code is

Code:

    var http_request = false;
var retvars = "";

function makeRequest(url, parameters, vars) {
http_request = false;
retvars = vars;

if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
// See note below about this line
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new
ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}

if (!http_request) {
alert('AJAX - Giving up :( Cannot create an XMLHTTP
instance');
return false;
}

http_request.onreadystatechange = alertContents;
http_request.open('POST', url, true);
http_request.setRequestHeader("Content-type",
"application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length",
parameters.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(parameters);

}

function alertContents() {

if (http_request.readyState == 4) {
if (xmlHttp.status == 0 || http_request.status == 200) {
// Call global AJAX function

AJAX(http_request.responseText,retvars);

} else {
alert('There is a problem with AJAX, please contact
support.');
}
}

}

the script is this

Code:

#!/usr/bin/perl

######################
# Set Error Trapping #
######################

use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
use warnings;
use strict;
# use diagnostics;

##################
# Use SQL module #
##################
use sql;

# Set File DSN to use
$sql::DSN = "filedsn";

# Read URL & Form data.
my %data = &get_data();

# Get Tune
my @rs = &getSQL("Charts","UserID,Plays","UserID = '$data{'mp3'}'");

# Update Plays
$rs[0]{'Plays'}++;
my $rec = &updSQL("Charts","Plays = $rs[0]{'Plays'}","UserID =
'$data{'mp3'}'");

my $disp = $rs[0]{'Plays'};

# Build Return AJAX data
my $catlist = "Content-type: text/html\n\n
$disp";

# Print AJAX data
print $catlist;
exit();

########

the script runs ok as the DB gets updated, for some reason FF is
erroring when the data is returned. It works fine in IE and the same JS
is used in other places and works in FF, so why is this script playing
up?

Thanks for the reply, i'm not a JS expert and alot didn't make sense to
me, but what really doesn't make sense is, the JS I wrote above is a
global file that ALL my AJAX requests use.

So this line : if (http_request.s tatus == 200) where it is erroring is
called all the time, I'm only getting an error for 1 of my scripts.

This to me is indicating that the returned data is different to other
data returned as those requests don't give me this error.

I could understand if FireFox always errored everytime for that line,
but it doesn't, so there has to be something else going on.

It's not because the network/server is unvailable, as the script called
runs and the database gets updated.

I can't see what is different between the scripts that work and the ONE
that doesn't.
