Problem With XmlHttpRequest (0x80040111 / NsIXMLHttpRequest.status) On Several Configurations
Sep 7, 2006
I came across the same error and have modified the code from
<a href = "" onClick = "javascript:somename( );">somename</a>"
to
<a href = "javascript:void(0);" onClick = "javascript:somename(
);">somename</a>"
In somename( ) fn i am using AJAX to retrieve the value and whenever i
click on that link [old code] it takes me to current page itself
without giving any AJAX response, that too only in Mozilla browser.
After that i changed the href attribute value to "javascript:void(0);"
and it works well without any error.
So this is the situation i came across. I dont know whether the above
info will help you guys?

in my javascript code I'm using a synchronous XMLHTTPRequest to periodically fetch a file from a server. Recently I added the "If-Modified-Since" header request (to reduce downloads if nothing is modified). Since adding the "If-Modified-Since" header request the javascript code still works with all browser (IE, FF, GC, AS) besides Opera.
The issue only happens if there is no new file to be downloaded: with the other browser I can see the 304 request status code, while with Opera (opening dragonfly) the request remains indefinitely as "in progress", the request status code returned being 0.

Yesterday I started rewriting the xmlhttprequest functions to an oo equivalent, but as it turns out, I don't get it right:
Code:
function Request()
{
this.req=init();
this.req.onreadystatechange = this.processedRequest;
//addEventHandler/attachEvent alternative
//doesn't work either
function init()
{
try
{
if(window.XMLHttpRequest)
return new XMLHttpRequest();
else
return new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
alert(e);
}
}
}
Request.prototype.send=function(url)
{
this.req.open("GET", url, true);
this.req.send(null);
}
Request.prototype.processedRequest=function()
{
if (this.req.readyState == 4)
{
if(this.req.status == 200)
{
response=this.responseXML;
res=response.getElementsByTagName('result')[0].firstChild.data;
func=response.getElementsByTagName('feedTo')[0].firstChild.data;
eval(func+'('+result+')');
}
else
{
alert(this.req.statusText);
}
}
}
expected usage:
Code:
var x=new Request();
x.send(url); //the processing function
//the eventtrigger should activate the callback function
//when the xml has been returned
It seems like the problem is that I don't get to my "this.req" in the processedRequest function. Can anyone see where the problem lies, it has been turning me crazy all weekend already.

Ive been playing around with xmlHTTPRequest and was wondering if i was
programming a part of my code wrong.
what i want to do is have the browser access another part of my site
using xmlhttprequest.
however, when i use xmlhttp.open("POST",
'http://xml.mysite.com/test.php')
it fails, but if i use xmlhttp.open("POST",
'http://www.mysite.com/test.php') it works. Is access to another url
restricted in xmlhttp?

I have something like this:
var xmlDoc=document.implementation.createDocument("", "", null);
but in opera xmlDoc.load(...) won't work, so I use:
XMLHttpRequest, and I have all needed code... let's say it works...
So I got serviceRequest.responseXML and is there a way to initialize xmlDoc
in my case ? I am asking because I have code that uses xmlDoc.load(...) in
FF and all code that's need to futher work with XML written. So this would
be comfortable for me to use xmlDoc instead of creating everything from
start.

I'm fetching some HTML files with XMLHttpRequest and dumping the
ResponseText into block elements; works fine except that single and double
quotes are being displayed as question marks (inside of a black diamond in
FireFox)
What's going on ? What is the workaround ? I've tried this:
divElement.innerHTML = x.responseText.replace(/?/g, "'")
but it does nothing ... even if it did work it would not be distinguishing "
from '

I would like to use the xmlhttprequest-object to send an http request
to my server. The http request is used to switch the light on through
home automation.
However it's not working, and I can't find the problem.
Could it be that the apache-server is located on 192.168.0.21 and that
the http request is sent to 192.168.0.21:8080?

function XML_request(func) {
var onreadystatechange= func;
this.method = "GET";
this.get = function(url) {
var request = null;
var state_change = function() {
if (request.readyState==4) {
if (request.status==200) {
onreadystatechange(request);
} else {
return null;
}
}
}
try {
request = new XMLHttpRequest();
} catch(e) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
return null;
}
}
if (request===null) {
return null;
}
request.onreadystatechange = state_change;
request.open(this.method, url, true);
request.send(null);
}
}
var req = new XML_request(function(response) {
response = response.responseXML
alert(response.getElementsByTagName('blah')[0].firstChild.data);
});
req.get('index.php?mode=blah&a=response')
i didn't like the examples I found so this is suitable.. I only tested in ie and firefox though.. so let me know what I may be missing.. or criticism in general.

I'm working on an application that uses ajax and we are going to have a version that people with browsers that don't support the XmlHttpRequest object. My problem is what's the best way to check this.
I have tried the following
var xmlreq = new new XMLHttpRequest();
if (!xmlreq){
// handle the browser stuff
}
In netscape 4.7 this results in an error that I don't seem to be able to recover from and I don't think this is the best approach to this problem.

I got a javascript function to pull contents from a php page, let's call this page B to the actual page, let's call this page A.
As I know when a page gets loaded the javascript on that page won't execute, am I right?
Now I need the javascript code on that page B to get executed. Is that somehow possible?

I'm loading a javascript within a webpage on domain A from domain B like this:
Code:
<script type="text/javascript" language="JavaScript" src="http://domainB/path"></script>
Works perfectly, the script loads and executes. But calling XMLHttpRequest.open accessing Domain B from within this script doesn't work: Permission denied.
Now, I know of the cross domain security rule, but why can I load a script from Domain B, but not make a request with XMLHttpRequest to Domain B? Alle the counter scripts do exactly this... Any advice?

I'm using Firefox 1.5 and FCKEditor in a CMS app. Everything works in older versions of Firefox but in 1.5 I get a javascript error saying that the XML file holding the styles can't be loaded. Here is the code where the xml request is made:Code:
FCKXml.prototype.LoadUrl = function( urlToCall )
{
var oFCKXml = this ;
var oXmlHttp = FCKTools.CreateXmlObject( 'XmlHttp' ) ;
oXmlHttp.open( "GET", urlToCall, false ) ;
oXmlHttp.send( null ) ;
if ( oXmlHttp.status == 200 )
this.DOMDocument = oXmlHttp.responseXML ;
else if ( oXmlHttp.status == 0 && oXmlHttp.readyState == 4 )
this.DOMDocument = oXmlHttp.responseXML ;
else
alert( 'Error loading "' + urlToCall + '"' ) ;
}
Everything works in IE but Firefox just gives the error that is set in the final else. Any ideas on how to debug further or fix (preferrably fix).

The code I am writing fetches a csv file with weather data and updates the contents of the page every 5 seconds. It works correctly as far as I can tell in Firefox, IE, and Chrome. In Safari it works correctly the first time it loads but gives the following error any time after that.
Error: NETWORK_ERR: XMLHttpRequest Exception 101 I've searched for this but couldn't find anything that seemed to be similar to the issue I'm having. The error occurs on the xmlhttp.send(null); line.
Code:
function getFile(url)
{
var file_url = url + '?t=' + ((new Date()).valueOf());
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();

I know in the new browsers you're not able to change the value of the status bar. Which is fair enough, i understand why and agree.
Although, i cant seem to get the value of the status bar. One used to be able to do window.status.
But that doesnt seem to work Wondered if someone could point me in the right direction.

I have the code below, and I want to know where and how do I make a status window appear on the pop-up window it generates:
<script type="text/javascript" language="JavaScript">
// Centered Pop-Up Window (v1.0)
// (C) 2002 www.smileycat.com
// Free for all users, but leave in this header
var win = null;
function newWindow(mypage,myname,w,h,features) {
var winl = (screen.width-w)/2;
var wint = (screen.height-h)/2;
if (winl < 0) winl = 0;
if (wint < 0) wint = 0;
var settings = 'height=' + h + ','
settings += 'width=' + w + ','
settings += 'top=' + wint + ','
settings += 'left=' + winl + ','
settings += features;
win = window.open(mypage,myname,settings);
win.window.focus();
}
</script>

I have a web app, written in Javascript, that communicates to a back-end
server via XMLHttpRequest.
The logic goes:
* Login
* Perform transaction
* (delay while the user does something)
* Perform transaction
* ...
* Logout
It would be really convenient if I could make the whole thing a single HTTP
connection. That way, I avoid needing IPC and session management at the
server end, and a single instance of a CGI script can represent the entire
session. When the socket gets closed, the CGI script terminates and
implicitly logs the user off. All very simple.
Can I use HTTP pipelining with XMLHttpRequest to do this? The docs seem to
say (it's quite hard to tell) that I have to call open() after each send(),
which will presumably create a new HTTP session. Can I 'persuade' the
browser to reuse an existing session?

I have a form in a webpage that I want to submit
and get the result back without reloading the page.
I've seen many times ppl using text/x-www-form-urlencode but I was
wondering if it was possible somehow to submit the form element
directly so I wouldn't have to process the form to put it in a string.

I am playing with the XMLHTTPRequest method to perform client/server
transactions. I have it set up right now so that when readyState is 4,
it takes the XML and processes it. This works great until there is alot
of data. In that case, the user will have to wait for the data to come
back which may take a minute or so.
I don't want the user to have to wait. Is it possible for javascript to
periodically (while still receiving more data) stop and display what it
has received thus far? I guess this would be considered a type of
streaming.
In mozilla/firefox, I have read that I can use readyState 3 to run my
callback function every 4096 bytes. I can then take those 4K, parse
them, and then continue on. However I have also read that IE cannot do
this. Since I need this to work in IE, is there a workaround?

I came across something I'm unfamiliar with -- there's an added check for window.location.href.indexOf("http")==-1 to see if the XMLHttpRequest send() completed, i.e.,
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
Does anyone know why this is done or which browser this (kludge?) is meant for?

I'm using the XMLHTTPRequest JavaScript object to fetch updated info
from the server.
The problem I'm having occurs on Windows 2000/IE 6. There is a very
long pause on readyState 3 (close to a minute, maybe more) but it
eventually gets to readyState 4. I have no idea why. The page works
just fine on Windows XP/IE 6.
There is no delay or hang up on the server side as far as I can tell
(if we get to readyState 3 is because the server already sent its
response).
Does anyone know what takes place between readyState 3 and 4 and why
does this happen on Windows 2000 but not on Windows XP? Code:

It is day two of the same problem (and day two of learning Ajax, day five of Javascript)
The current code (below) does nothing; it does not go into the showContents function. Switching the order of some items would cause it to enter the function, but it would always alert that the xhr status was 0. I guess this is an improvement?
php doc that is getting requested (I don't think the error is here as the problem is that it is not even initializing):
Code:
javascript code that is requesting the information:
Code:
I need to pass the num variable because the fields I am dealing with are part of a bunch of fors that create an unspecified number of fields titled 1source, 2source, 3source, etc.

I would like to pass a link through the same page using XMLHttpRequest or what ever is best without reloading the page eg; I have :
<a id="prev"><? echo $prev;?></a>
<a id="page"><? echo $page;?></a>
<a id="next"><? echo $next;?></a>
if someone click on the link id='next' then they go to the next page where at the moment in the URL it says: default.php?page=3
