Why are Firefox 1.5 and 2.0 no seeing this method when IE6 does"
here's the import statements followed by the function imported, followed by the script trying to create a XMLHttpRequest, followed by the in document script using the imported createRequest() function. Code:
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).
I am trying to create an xmlhttprequest object to update the shopping cart on my web page without submitting the entire page to the server for processing. However, what I have done so far is not working. All that is happening when I click the "update cart" button is the page sort of flashes and the check marks in the remove item check boxes disappear. The first code snippet is the "traditional" way of submitting the whole page to the server for processing - and it works. The second snippet is what I have done to try and implement AJAX to submit only the shopping cart - and it does not work.

I am trying to create a script that would output two variables - X Controllers and Y Pilots.
Basically, I would need to capture the contents of the following webpage and extract those two numbers from the second line of text.[url]
I think this may involve XMLHttpRequest but I am not sure.
Does anybody know how to make FireFox to cache data that comes via
XMLHttpRequest? Here is the issue I deal with:
- On the web server (apache2) I have a static xml file test.xml
- When I download test.xml using XMLHttpRequest, FireFox always gets
complete test.xml from the server, thus not using the browser cache
(apache sends 200 OK back to FireFox).
- If I look into the HTTP request and the HTTP response, I can see
that FireFox seems to always set the following request headers:
Pragma: no-cache
Cache-Control: no-cache
- Apache always sets Last-Modified and ETag headers in a response.
I tried the same JavaScript code with IE, and IE definitely relies on
its cache: I can see in Apache logs responses with 304 Not Modified
code for IE, also HTTP requests from IE have If-Modified-Since and
If-None-Match headers. I didn't find any difference in responses Apache
provides for FireFox and IE.
i am new to AJAX but i havejust managed to write one of my first basic scripts. What it does is takes all the news items out of a database and lists them as links. When you click a link i want all of the data that is linked to that news item to display underneath. Now i have got this to work except it will not work in Firefox, all other browsers it is fine.

syntax error: missing } XML expression (on column 56)
I'm currently promoting a website that requires internet explorer. I have been showing a page that tells non-IE users (mainly Firefox users) to switch to IE in order to view the page.However instead I want it so that if the current browser is not Internet Explorer it loads the website in Internet Explorer (basically a popup that is in Internet Explorer, and not in whatever browser the user is using).

I have a table (tables are for tabular data) with patient information. The user can click the row to select it and when they do the right part of the interface loads some additional information on the patient - quick lookup info if you will, but also provides links to tasks involving that information - edit, view case history, etc.I'd like to replace the default right click behavior on the rows to create a pop up menu next to the point of click that links to the same list of options for the convenience of the more savvy users.The project is being built with prototype so no jQuery please. The site is a corporate intranet where Firefox is the only browser it is *required* to work in. It would be nice to have it work in webkit.

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.
1. - I am new to this
2. - Using the following .js file:
Code:
function makeObject(){
var x;
if (window.ActiveXObject) {
x = new ActiveXObject("Microsoft.XMLHTTP");
}else if (window.XMLHttpRequest) {
x = new XMLHttpRequest();

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.
While accessing my web service i am getting XMLHttpRequest status=0 in Crome/Mozilla and in IE getting XMLHttpRequest status=406. What is the solution for it so that i will successfully get responseText from server? I have tried accessing my html code with localhost but its getting same error,while when i run my code in that localhost location through local drive then it's working. why this is happning i didn't get?
View 1 Replies View RelatedI 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?
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)

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 am trying to implement XMLHttpRequest to a new website, but when I
include HTML, the code appears as is, instead of the formated HTML. Please
have a look and click the 1st link ("L'Association") on top (yello
horizontal bar on top): Code:
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?
