JQuery :: 1.4.2 - AJAX GET Requests Do Not Follow Response Code 302?
Oct 25, 2010
I'm having problems performing a simple load(...) request to bring in HTML content from a partner Oracle system within the same domain. Our portal has a built-in SO connection will handles security for me transparently. However during the process it initiates a 302 temporarily moved response which seems to trip up an AJAX request, but doesn't trip up Firefox when accessed through the address bar. If I use the same URL in an IFRAME it's totally fine.
After tons of googling, searching the forums, and the bug tracker database I cannot find anyone who has experienced this problem. Before I open a bug ticket I'd like community feedback to help me see if I am doing anything wrong.
My AJAX call looks like this in Javascript:

I have managed to succesfully post the data to the php page... (i can see using firebug that it IS being sent) but i get a message Quote: Apache HTTP Server has encountered a problem and needs to close and the response is empty... what am i doing wrong?is possibly something to do with the space in the value of the options?
Code:
<head>
<title>Auto suggest</title>
<script src="ajax.js"></script>[code].....

It looks like IE is caching the response for some AJAX requests here. The app I'm working on is a catalog of sorts. Clicking the link for a category loads a set of "items". Those, in turn, may be deleted from the admin view. The delete works fine (I checked the DB) but, when loading the same set of category items, I'm seeing the list unchanged. That is, the thing that was deleted is still there. Sorry for the crap explanation but I'm not really sure of a better way of putting it. Bottom line is, has anyone seen this sort of behavior with IE before? Can it cache the result of an AJAX request like that? And, if so, how can I guard against that? Can I set cache-control headers for an AJAX request?

Very intermittently, I am finding ajax requests submitted with jquery are being submitted twice, once with parameters, and once without parameters. The code looks something like this:

I'm trying to launch two ajax requests at same time. I'm expecting result from the first later than the second. The problem is, it won't return me any result from the second request untill first one is returned.
Check it out :
$.post("sendMail.php");
getSendInfo();
setTimeout(getSendInfo,5000);
[code]....
I'm getting response from the $.getJSON function only when the $.post is over. Is this a bug or a mistake from me ? My aim is to launch a long request and fire multiple other requests to check how is doing the first one.

I have a element when click, it will trigger some other elements to be selected. and those elements will trigger elements in next level.
It is a three levels hierarchy so to speak. but each element will send an ajax request when selected. Those requests will become out of control especially when I repeatedly click the root element.
Can I queue those XHR request in a queue and send them one by one? or maybe add a delay before send so that they can collect their information into one batch request and send one request after that.

I have a page that relies on AJAX for content manipulation. Once a person selects a radio button, a request is made through $.getJSON() to get the replacement content. This works in all browsers. Once the new content is loaded, there are 3 more calls to $.getJSON() to change more content (on other tabs in jQuery UI). This works in all browsers except for IE.
I understand this is a Microsoft problem, and not a jQuery problem, but I am wondering if there is a way to manipulate the jQuery calls to get them to work in IE. I did try replacing $.getJSON with $.ajax, and even set async to false. None of those three methods worked in IE. I noticed the problem when my loading div was still displayed in IE. Using Firebug Lite, I saw that only one request was made, rather than four.

I am developing a fairly complicated application with a lot of JavaScript and making use of JQuery. The application repeatedly makes simultaneous GET requests.
I am looking for a way of assigning a unique token to each request when it is made, so that I can store information about that request and cache the request / response combo, when using $.get() (or potentially $.ajax() if required for the extra functionality).
So far I have not had any joy and after a while googling this am none the wiser. I have used similar functionality in Flex 3 with the AsyncToken object which can maintain data between HTTP request / response.

I'm working on a php/jQuery application, I want to display a loading image automatically every ajax request, without writing code for every ajax request. Is there anyway to do this.

When a pending ajax request is aborted in IE browsers there is a new global object called "jQuery" + timestamp, for example "jQuery16405272192696596443".
This happens in every IE from 6 to 9 but not in Chrome, Safari, FireFox in their current stable versions. I am a bit lost and found nothing similar. I created a little test page to determine whether it started due to some own code or just in this little piece.
Example HTML:
<!DOCTYPE html>
<html>
<head>

I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.

I have this function among many that houses forms. I'm also using an ajax page that is supposed to deal with form's entries and insert everything into my DB and I don't know how to separate the different requests on the ajax page so that it can do what the correct request is.

This might seem like a silly question..First issue. If i have a response and i'd like to update both text div and a status div how would i go about doing this. I've seen that jQuery has a few options such as OnSuccess etc?
Say that i post a comment and obviously you'd want to update some kinda statusbar on your website with the info that the message was posted successfully with ajax. (otherwise it might slip by the user unnoticed since ajax is kinda discrete)
Would it be a good way to for instance check the responseText if it contains anything and if it does you simply write a successmessage by grabbing a div from JS and if the responseText contains a custom error code lets say 1 you'll update the statusbar with a deny message?
Second thing. I've currently created an Ajax search on my site which activates whenever the user press or unleash the button. The issue is that if the user types fast enough it comes stuck showing the Loading.gif constantly. Could this be due so many requests opening and that i have a sleep on the server-side and if so how would you do it instead? I am using a serversleep of 1 second to have the Ajax pic appear consistently.

I have a jsp page using ajax that has a button with an action. The action sends multiple ajax requests. The response from these requests is to be used to update a progress indicator to show the servers current progress. I can see from the debug that I am getting the 1st response. I think it is the way how I have implemented the further requests. I think this is down to my javascript knowledge, which isnt very much. Also I assume using multiple requests in this way is the correct thing to do? I have spent ages trawling the internet trying to get a solution.

$.ajax({
url: "someurl.php",
success: function(data){
//..process on success..
},
I want to reload the page if session is timed out so I am checking the user session at PHP file and if session is timeout I am sending error code. if I get the error code in response I will reload the page so that it will load login page.

I'm encountering an AJAX problem when I try to execute multiple AJAX requests at the same time. What I want to do is delete a message and display the status (succes or failure) of that in div1, and refresh the messages on the page in div2. This needs (for as far as my knowledge reaches) two AJAX actions from which I both need the responseText.
The problem:
What happens when I execute my script is that the second action (refresh a part of the page) happens before the deletion is executed. The result of this is that when the deletion has been executed, the page is already updated, and the deleted message is still there.
The script
What I now have is:
function doAjax(url, element_id, img_url){
var ajaxObject = createAjaxObject();
ajaxObject.open('GET', url, true);
ajaxObject.onreadystatechange = function(){
if(ajaxObject.readyState==4 && ajaxObject.status==200){
document.getElementById(element_id).innerHTML = ajaxObject.responseText;
delete ajaxObject; .....

I need to send 15 requests to my server and get results, these results are queries to other sites. I then update my page with the results. I need to know if I am taking the correct approach, as things are working a bit slow, and i.e., seems the be as slow as a snail.
Here is my function for the first request
Code:
function one(){
var xmlHttpa=null;
try{
xmlHttpa=new XMLHttpRequest();
} catch (e){
try {
xmlHttpa=new ActiveXObject("Msxml2.XMLHTTP");
} catch (e){
try {
xmlHttpa=new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
alert("Your browser does not support AJAX!");
return false;
}}}
xmlHttpa.onreadystatechange=function(){
if(xmlHttpa.readyState==4){
document.getElementById('resulta').innerHTML = xmlHttpa.responseText;
var el = document.getElementById('showMessagea');
el.parentNode.removeChild(el);
applystyle();
}}
xmlHttpa.open("GET","one.php",true);
xmlHttpa.send(null);
}
I then call this function and others from my page, one(); two(); etc. Am I correct in my approach?

I am making a call like -
$('#display').load(adnwurl, function(response, status, xhr) {
alert(response);
});
And also tried with -
$.get(adnwurl,
{},
function(data) {[code]...
In both the cases I am getting an empty response instead of expected html response.If I just copy paste this adnwurl in browser, I do get a proper html response. Its not working with ajax call.
adnwurl = "http [url]...site_id=4764&partner_id=70606a913077034c&timeout=5000&version=1.5&language=jsp&format=wap&testing=1&target_params=AGE=>29||DOB=>1981-08-[code]....

I'm using $.ajax for an ajax request and I've setup a basic html form and if there are errors in the form when the user submits them my server side script is returning them in an array to the client with the errors.
If there are multiple values in the array, how do I display each error on its own line either using <li> tags or even just a <br/>? I'm injecting the ajax response into a div using .html() but how do I iterate the array within that div so I get one error message per line?
Do I need to construct the HTML on the client side after the ajax response has come back or should I do this on the server side before the data is even returned to the client? Right now I'm returning a raw array so that is why I'm asking the question about how to format things up and get the form errors into my div.

What I'm doing is creating a div element dynamically when the user clicks on a point in the page. Once created I create a record in my database table the corresponds to this div element and save information such as the width,height, x coordinate, and y coordinate of the element. This is done via AJAX accessing my web service. The weird thing is, I get really fast responses 80% of the time but 20% of the time, its taking a lot longer. For example, I would get a response after 50-100ms and at times I would get it in 2 seconds What do you think is the source of this problem?

I would like to send my form data to a php file but not to get any response. I want to send an ID so that PHP can do MySQL search and generate a PDF file. Problem seems to be that PHP is responding something back to HTML and that is messing my code. So I just want to send the data and run the scripit in PHP so that nothing is returned back to HTML.
