AJAX :: Document.onclick The Bar.php Call Does Not Work And XMLHttpRequest
Aug 20, 2010Here's my problem code:
document.onclick=handler;
function handler(e) {
//do stuff
var params = "something";
var request = new XMLHttpRequest();
request.open("GET", "http://www.foo.com/bar.php?" + params, true);
[Code]....
Now is user clicks something else but not a link everything works just fine. But if she clicks a link, the bar.php call does not work (never comes to the server). If I change the call to a synchronuous one request.open("GET", [URL] false) also clicking a link works fine. But I would of course prefer the async way.

Mar 10, 2006The following script works fine in IE6. In FF 1.0.7, it doesn't display the response text. The alert()'s in the script show that:
1) the script successfully creates the request object
2) 'http_request.status' starts off equal to 0
3) the readystate displays: 1, 1, 2, 4
4) an error occurs when the script tries to access the .status property of the request object after the request has been sent and the readyState reaches 4(line marked in red below).

JQuery :: Ajax Function Does Not Work
Jan 2, 2011I'm sure that "insert.php" works because I've tried the
<form method="POST" target="insert.php">
And it adds to the database through "insert.php". But when I remove the
'method="POST" target="insert.php"'
And replace it with $.ajax() it won't work.
Here's the code:
$(document).ready(function(){
$("#submit_wall").submit(function() {
var message_wall = $('#message_wall').attr('value');
var message_wall = message_wall.replace(/</g, '<');
var message_wall = message_wall.replace(/>/g, '>');
var message_wall = message_wall.replace(/<.*?>/g, '');
var FeedUNum = $('#FeedUNum').attr('value');
var FeedConn = $('#FeedConn').attr('value');
$.ajax({
type: "POST",
url: "insert.php",
data: "FeedUnum="+FeedUNum+"&message_wall="+message_wall+"&FeedConn="+FeedConn,
success: function(){
$("ul#wall").prepend('<li style="display: none;">'+message_wall+'</li>');
$("ul#wall li:first").fadeIn();
}});
return false;
});});

Ajax :: XMLHttpRequest Stuck At 0
Sep 27, 2010It 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?

JQuery :: .ajax Success With XMLHttpRequest In 1.3.x?
Jan 15, 2011My app recently upgraded to 1.4 and as such started using the XMLHttpRequest in the success callback of the .ajax function however we been forced to roll back to 1.3.2 due to performance issues with IE7 (forced to use in a corporate environment) Is there any way to get access to the XMLHttpRequest after an ajax call? If not, would anyone be so kind as to point out if its possible to modify the 1.3.2 source to add the parameter to the success call back like in 1.4? I am hoping its a simple modification however I could be wrong. We are set to upgrade to the lastest jQuery when we get a browser upgrade to IE9 but that could be up to a year away and I would really like to continue to use the XMLHttpRequest in my app as its a lot faster than my old approach.
View 2 Replies View RelatedAjax :: Create An Xmlhttprequest Object ?
May 7, 2011I 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.

AJAX :: Reading XMLHttpRequest.responseXML?
Feb 8, 2009I am trying to build a very simple Ajax example with JavaScript and PHP. Basically, the goal is to populate a select list with values dependent on the selection in another list. I am able to do a GET from a server-side script and I see the XML displayed correctly in XMLHttpRequest.responseText. However, when I try to check XMLHttpRequest.responseXML, I am not able to get anything out of it. The alert() shows it as an "Object", so it's not null. I have tried getElementByTagName() from both responseXML and responseXML.documentElement, each time giving a legitimate inner tag, but nothing comes out. What is the correct way of doing it? This is my JavaScript and HTML code:

JQuery :: Ajax - Don't Declare XMLHttpRequest Object
Mar 16, 2011I find ajax with jquery more confusing than with regular JS, b/c in jQuery you don't declare XMLHttpRequest object.. so how do you do something like:
In example I mention here,[url] namely [url] I don't understand where var 'msg' is declared, I know it comes from the back-end, but HOW is it passed to the front-end? (how do you do this w/o responseText or something similar?)
I'm trying to connect to a send-mail jsp with ajax.. the email is not getting sent.. I want to test if the ajax connection is being made at all.. don't know how do it w/o something like xmlHttp.responseText
This is my jQuery ajax code for connecting to send-email jsp:
var dataToSend = "name=sName&email=sEmail&msg=sMsg;

View 1 Replies View RelatedAJAX's XMLHttpRequest Used To Bring Back PDF And Excel Docs?
May 14, 2006Can I use the XMLHttpRequest object to call a url which would generate a PDF and then display it to the screen?
I'm new to AJAX and I'm very interested in using it to asychronously bring back documents with a content-type that IS NOT text/plain or text/html (like a PDF or Excel document) and then display that document to the screen. I have a web application that dynamically generates PDF and Excel documents. A user may have to wait a minute for the new doc to be created and displayed to the user. I want to put an animated notice saying the doc is being generated similar to what you see when you execute a search on a search engine. I've tried using animated gifs (with frames, etc.) but they don't work. As soon as a request is sent for the PDF, the browser halts the gif in IE. If I could instead call the URL that will produce the PDF asynchronously, then I could display the animated gif and call the PDF at the same time. Once the PDF is generated, I want it to then be displayed to the screen.
AJAX :: XMLHttpRequest - FF Vs IE - Gets A Stock Quote From Yahoo And Displays It
Mar 7, 2011I've put together a function for screen scraping, just to see if I could do it. Basically, this gets a stock quote from Yahoo! and displays it. It works with no issues in IE7. FF and Chrome, however, it does not work. It will not display anything. Error Console is not returning any errors, and I'm a total novice when it comes to troubleshooting with FireBug.

I'm sure it's something simple, something I've overlooked. I'm beginning to think it might be with the trenary conditional setting the method.

AJAX :: Cross-browsing Request Work Around - Every Browser Doesn't Work ?
Jun 14, 2010The "Permission denied" cross site issue.
I have to check from my external domain if a service is running on localhost:8080 of a local machine.
I'm using XMLHttpRequest to do it.
I'm checking a local-web-server, not a file.
Every browser doesn't work, but Firefox. So I'm looking for a work-aorund.
An iframe? a flash swf? an applet java? HTA applications?
A side question is, why does FF work? Because it's a local-web-server?

AJAX :: Functions Never Work With PHP - Tree Folder Which Calls Another Page To Be Loaded Into A DIV By AJAX Again
Apr 14, 2009I'm creating an AJAX page that is built using a PHP Class, ie the php looks a bit like this: PHP Code:
$wp_page->addjs('../var/savepolicies.js')
$wp_parser->page = "userpolicywindow.php";
$wp_parser->addlink("Home","../index.php","");
$wp_parser->addlink("Logout","javascript:logout();","");
$wp_parser->getpageid("501");
[Code]...
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?

JQuery :: Google.load Function Doesn't Work If Called From Ready Function?
Jul 1, 2010I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below
page.html

loadGoogleStuff();
function loaded() {
console.debug("in loaded function");
}

window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.
