Re: Simple Ajax request error

2009-10-19T14:28:07Z

If you are new to javascript and ajax in general I would stick to the normal method of coding and define each function as its own instead of trying to declare the function on the spot. It will make debugging much easier. I would also recommend you read this article to get a great understanding of ajax and how everything works:
Simple Ajax Request With PHP and Javascript

Just substitute the PHP code for your JSP code and all should work.

As for your script, I would run the following and tell me what the alert says that you get back. I think the problem may be in your .jsp file because I tested the code in firefox and it seems to work fine on my end (I just replaced the home.jsp with a basic php hello world script). Also what browser are you using to test this? Sometimes a send(null) can cause issues depending on the browser.

<html><body><script type="text/javascript">
function ajaxFunction()
{
var xmlHttp;
try
{ // Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{ // Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
alert("Your browser does not support AJAX!");
return false;
}
}
}

xmlHttp.onreadystatechange=function()
{

if(xmlHttp.readyState==4)
{
document.myForm.time.value=xmlHttp.responseText;
}
alert(xmlHttp.status);
}
xmlHttp.open("GET","/home.jsp",true);
xmlHttp.send(null);
}
</script>
<form name="myForm">
Name: <input type="text" onkeyup="ajaxFunction();" name="username" />
Time: <input type="text" name="time" />
</form>
</body>
</html>

AJAX request cannot be created - (NS_ERROR_ILLEGAL_VALUE) [nsIXMLHttpRequest.open] error

2008-09-30T04:29:43Z

Hi,

I am trying to develop a generic AJAX object so that I can reuse it across my application.
Following is the code for it -
function async(url,cbFun){
this.req;
this.callBackcbFun;
this.url=url;

this.initRequest=function (){
if (window.XMLHttpRequest) {
this.req = new XMLHttpRequest();
}
else if (window.ActiveXObject) {
this.req = new ActiveXObject("Microsoft.XMLHTTP");
}
}

this.doAjax=function() {
this.initRequest();
this.callBack = cbFun;

if (this.req != null){
this.req.onreadystatechange = function(){
if (this.req.readyState == 4){
this.callBack(this.req.responseText,this.req.responseXML,this.req.readyState,this.req);
}
else{
// Invoke Stalker...
}
};

this.req.open("GET", url, true);
this.req.send(null);
}
else{
alert ("No Request Object created!!!");
}
}
}

But, I recieve the following error -

Error: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIXMLHttpRequest.open]" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: http://localhost:8080/wf/script/async.js :: anonymous :: line 29" data: no]

Could someone please help me about this..

Thanks,
Amit

I guess the workaround is just to set the display to block at your application's own leisure...

All the page cookies are sent on the ajax request. So once you login
you can track things with the standard cookies.

You can enforce the auth in the registered methods or at the top of the
server file or whatever your ajax entry point is.

Problem synchronizing Ajax calls

2008-08-12T13:55:47Z

I have a JSP that renders up to 6 SELECT elements. Each SELECT is dependent on the preceding SELECT.
At startup the app grabs a default value for each SELECT and uses this value to pre-select an option.
This option value then becomes a retrieval argument value in a SQL stmt that retrieves data for the following SELECT.
My problem is this:
After the first Ajax call the functions containing the next Ajax call is firing before the code to pre-select the preceding SELECT has completed.
Hence an incorrect argument is passed to the SQL.
I have tried using setTimeout but IE gets in the way and reports 'Slow running script bla bla'. Setting various Advanced IE options
suggested by several Google searches hasn't helped. One suggestion involved setting a Registry entry. That did not work either, and
since this is commercial software it's difficult to ensure all users make the necessary Registry changes even if it had worked.
I've also tried setInterval. This will fire a function that can test for a specific variable value that I can set when the
scripts have completed, and then I clearInterval when I find the value has been set.
This doesn't work too well either.
Using IE is mandatory in this case. :evil: :evil:
Any one have any suggestions that might resolve this issue?

Wade: sounds like an encoding problem spaces can be encoded as + so i'm
guessing thats the problem can you open up a bug

As far as writing docs there are a couple options. You can either start
making edits in the wiki, or if you want to target the pear manual
you'll want to get on the pear-doc list and ask for some help getting
started with the setup for that.

btw, I just remembered, when I wrote quickform_rule_spelling, I googled a way to
get a workaround for ie6 for fixed positioning using expressions. The result
was acceptable, with the exception that when you scrolled it appeared jerky/jumpy.

I think this may have been the page that I got it from:

Ok great, I've already started to play around with the javasscript. One thing I
didn't realise is that it will only ever send that first request once per page
load because the interval id is never cleared unless stop() is called. Is this
correct?

Also, can you tell me what the effect of setting "singleOutstandingRequest"
should be?

SingleBuffer Queue Behaviour

2008-05-30T04:42:27Z

Hi all,

Just a question about the behaviour of the SingleBuffer queue.

Is it worth adding an option to disable the immediate sending of the first request? The reason why I ask is because as I was using HTML_QuickForm_Livesearch and tracking the ajax requests on my server while playing with the interval delay, I found it strange that for longer delay times, I was still getting a request for the first character that I had typed. At first I thought this was a bug and then I read the javascript and found that it was deliberate. My intention is to get a livesearch text field happening but delay sending a request to the server until the user had stopped typing in the text field. So would this be a reasonable request? I could imagine that in the future I would want similar functionality.

Regards,
David

Do you have a pear data dir. The JavaScript files get installed to that by the installer.

If you moved things around after install time then things will get broken.

There is a property you can set to update the location, jsClientLocation i think (though that could be wrong)

Re: AJAX Error 0x80040111 (NS_ERROR_NOT_AVAILABLE)

2008-02-21T09:44:20Z

> Hi!

Thank you for the reply. I'm not sure how to adapt the sample code you sent me to my case, due to my dreadful Javascript coding abilities. Although I understand the inner logic I don't recognize some other underlying layers of functioning. If I sent you my AJAX Javascript code could you kindly try to adapt and comment it.

The thing is that at this moment I am implementing some GIS functions on PHP/PostgreSQL/PostGIS that are rather complex and time demanding. Also if you agree I would be very proud to make a reference to your efforts on my MSc or other related works.

-- Best regards

Your not in the correct state to read that variable.

Check out http://svn.bluga.net/HTML_AJAX/trunk/js/HttpClient.js for an
example on how it should be done.

_readyStateChangeCallback is the method that checks the status

AJAX Error 0x80040111 (NS_ERROR_NOT_AVAILABLE)

2008-02-19T19:28:55Z

Hi!

> I'm having some problems to debug some AJAX oriented code that follows:

function sendAjaxRequest(formIndex, outputElement, flagElement){

var Form = document.forms[formIndex];
var requestString = getRequestString(Form);
var XMLHttp = makeXMLHttpObject();

// Output the status element
build_loading_flag(flagElement);

XMLHttp.open("post", Form.action, true);
XMLHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");

XMLHttp.onreadystatechange =
function (){
if(XMLHttp.readyState == 4){
// This is resultant response form the server
showResults(XMLHttp.responseText, outputElement);
destroy_loading_flag(flagElement);
// Resets the form content
//document.forms[formIndex].reset();
}
else{
if (XMLHttp.statusText != "OK"){
alert("An error has occurred. Status: " + XMLHttp.statusText);
destroy_loading_flag(flagElement);
}
else {
destroy_loading_flag(flagElement);
}
}
};
// This would be set to null in case of a GET request
XMLHttp.send(requestString);
}

Every time I invoke this function Firefox error console throws the following message at the line that calls the statusText attribute:

[Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.statusText]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"

Can someone help me out on this one. I'm not proefficient in this matters.

and the ajax output goes to

var remote = new ajaxclass({});

some parts of my posts didnt get throu the nable security and i think i posted a bug :(

< h e a d e r >
< script type="java.... src="sever.php..." >
< script type="java.... >
var remote = new ajaxclass({}); // we need to start the class too

the js eventcall should then be -> onclick="remote.updateorder('company','<?=$pageID?>');"

now it should work ;)

hey lewis!

first see the examples how to setup the PEAR_AJAX server.php and to start
the class. when you got this, you should end up with a class you start via
the server.php. in this class you can put functions to interact with your
form. i show you an example how i made this for a project from myself...

in this func a user uses a radiobutton so re-sort the search results

class ajaxclass {

function ajaxclass(){
}

function updateorder($order, $pageID){

if(!empty($_SESSION['query'])){

require_once 'HTML/AJAX/Action.php';
$objAction =& new HTML_AJAX_Action();

if($order=='zuname'){
$_SESSION['query']['order'] = 'zuname';
}

if($order=='company'){
$_SESSION['query']['order'] = 'company';
}

if($order=='lastEdit'){
$_SESSION['query']['order'] = 'lastEdit';
}

if($_SESSION['query']['output']=='adressen'){
$output = utf8_encode(queryOutputAdresses($_SESSION['query'],$pageID));
}else{
$output = utf8_encode(queryOutputMarketing($_SESSION['query'],$pageID));
}

$objAction->assignAttr('result', 'innerHTML', $output); // 'result' is
the ID of an html element
return $objAction;
}

}

on the HTML side i call this func with:
onclick="ajaxclass.updateorder('company','$pageID');"

and the ajax output goes to

src="server.php?client=all&stub=ajaxclass">

sorry my english is not the best and this example might not be perfect
either, but maybe you get a glimpse how to use PEAR_AJAX

have fun,
superfly

on the HTML side i call this func with:

and the ajax output goes to <div id="result></div>

in the header area i got
<header>
<script type="text/javascript" src="server.php?client=all&stub=ajaxclass"></script>
<script type="text/javascript">var remote = new ajaxclass({});</script>
</header>

For instance if a customer check a checkbox it will make a query to database and update the content div.

Best way to do AJAX

Hi,

I am working on a web page, which has check box, radio button, slider, etc. What I want to accomplish is to display some data retrieved from database using the criteria enforced by those controls. I am using MDB2 for database accessing and it works great. My question is what method I should use for HTML_AJAX to interactive with customer. For instance if a customer check a checkbox it will make a query to database and update the content div.

Thanks,

Re: RE : RE : AJAX requests which fail silently ?

2007-12-03T09:43:05Z

The custom handler is only used on the specific remote handler where its
set so everything else is still going to use the default handler.
