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.
I'm trying to create a script that will call a flickr rest method and output its XML. I have written the following code, but it seems to not work. I am stumped, and was wondering what I am doing wrong. I have uploaded my code to [URL]

I'm very new to JS so I am having trouble understanding how to do what is probably a simple task.I have the following script setup to parse variables from a gps mashup.
Code:
<script type="text/javascript">
this.send_query = function() {
var self = Edit;[code].....
It seems to be working just fine but now I want to store the variables from that script into a form, then submit the form so it passes all the JS vars.
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 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.

var XMLHttpRequest;
try{

}
syntax error: missing } XML expression (on column 56)
What about if I had something like this where a for loop creates all the variables for you...rather than having to write them out on individual lines like so:
for(i = 0; i < myForm.elements.length; i++) {
tempControl = myForm[i];
var e = tempControl.name;
var [e] = document.myForm[e].value;
}
As oppose too:
bodyChooseColour = document.myForm.bodyChooseColour.value;
bodyChooseFont = document.myForm.bodyChooseFont.value;
bodyChooseFontSize = document.myForm.bodyChooseFontSize.value;
bodyChooseFontColour = document.myForm.bodyChooseFontColour.value;
etc...
However, the for loop does not work...Firefox JavaScript console reports 'Missing variable name' pointing to the 'e'.
Anyone know how to get Javascript variables into PHP variables or a MySQL database? Full question in the PHP section.
View 2 Replies View RelatedI have some JavaScript which is splitting out the different variable elements from the URL.Now, how do I set the internal variables?Then I want to set the variable ScriptHeading to be Change and the variable ScriptType to be NewThread.I keep finding all sorts of lovely code showing how to split out the various sections in many different ways, but I can't find anything on how to actually set these variables.
View 1 Replies View RelatedYesterday 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.
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?
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 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.
