I keep receiving this error when I do some Ajax calls...
It may even be something to do with Geocoding but I really have no idea how to capture the error to display something useful to users... or even how to solve the problem as it seems to just be referencing some kind of pointer or something :S 0x2ef3
SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3, Could not complete the operation due to error 00002ef3.
An image might be more helpful than the error message:
Any ideas at all?
My code fires off 10 ajax calls in 1 second to be processed by geocoding server side.
The error comes up intermittently. Sometimes I get geocoded results and sometimes I get that error. I would say I get it 10% of the time. It completely stops the ajax call from firing my error handler in jQuery.
This is the fix that worked for me. There is invalid mime or bad characterset being sent with your json data causing that errror. Add the charset like this to help it from getting confused:
$.ajax({
url:url,
type:"POST",
data:data,
contentType:"application/json; charset=utf-8",
dataType:"json",
success: function(){
...
}
});

Could not complete the operation due to error c00ce56e
We also encountered similar problems. However, setting the charset as noted in the previous comment did not help. Our application was making an AJAX request every 60 seconds and our webserver, nginx, was sending Keep-Alive timeout at 60 seconds.
We fixed the problem by setting the keep-alive timeout value to 75 seconds.
This is what we believe was happening:
IE makes an AJAX request every 60 seconds, setting Keep-Alive in the request.
At the same time, nginx knows that the Keep-Alive timeout value is ignored by IE, so it starts the TCP connection close process (in the case of FF/Chrome this is started by the client)
IE receives the close connection request for the previously sent request. Since this is not expected by IE, it throws an error and aborts.
nginx still seems to be responding to the request even though the connection is closed.
A Wireshark TCP dump would provide more clarity, our problem is fixed and we do not wish to spend more time on it.
I received the same error (SCRIPT7002: XMLHttpRequest: Network Error 0x80004004, Operation aborted), in our case it was because of JavaScript's same origin policy.
Our web app was making a JQuery AJAX call to our server on Port 8080. The call was getting intercepted and re-routed over SSL (due to server rules mandating that incoming traffic use SSL).
Once we made our web app load through the SSL port the issue was fixed.
I had this problem, a an AJAX Post request that returned some JSON would fail, eventually returning abort, with the:
SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3
error in the console. On other browsers (Chrome, Firefox, Safari) the exact same AJAX request was fine.
Tracked my issue down - investigation revealed that the response was missing the status code. In this case it should have been 500 internal error. This was being generated as part of a C# web application using service stack that requires an error code to be explicitly set.
IE seemed to leave the connection open to the server, eventually it timed out and it 'aborted' the request; despite receiving the content and other headers.
Perhaps there is an issue with how IE is handling the headers in posts.
Updating the web application to correctly return the status code fixed the issue.
Hope this helps someone!
This issue happened in my project because of an ajax GET call with a long xml string as a parameter value. Solved by the following approach:
Making it as ajax post call to Java Spring MVC controller class method like this.
$.ajax({
url: "controller_Method_Name.html?variable_name="+variable_value,
type: "POST",
data:{
"xmlMetaData": xmlMetaData // This variable contains a long xml string
},
success: function(response)
{
console.log(response);
}
});
Inside Spring MVC Controller class method:
#RequestMapping(value="/controller_Method_Name")
public void controller_Method_Name(#RequestParam("xmlMetaData") String metaDataXML, HttpServletRequest request)
{
System.out.println(metaDataXML);
}
I had this error for some time and found a fix. This fix is for Asp.net application, Strange it failed only in IE non compatibility mode, but works in Firefox and Crome. Giving access to the webservice service folder for all/specific users solved the issue.
Add the following code in web.config file:
<location path="YourWebserviceFolder">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
I have stumbled across this questions and answers after receiving the aforementioned error in IE11 when trying to upload files using XMLHttpRequest:
var reqObj = new XMLHttpRequest();
//event Handler
reqObj.upload.addEventListener("progress", uploadProgress, false);
reqObj.addEventListener("load", uploadComplete, false);
reqObj.addEventListener("error", uploadFailed, false);
reqObj.addEventListener("abort", uploadCanceled, false);
//open the object and set method of call (post), url to call, isAsynchronous(true)
reqObj.open("POST", $rootUrlService.rootUrl + "Controller/UploadFiles", true);
//set Content-Type at request header.for file upload it's value must be multipart/form-data
reqObj.setRequestHeader("Content-Type", "multipart/form-data");
//Set header properties : file name and project milestone id
reqObj.setRequestHeader('X-File-Name', name);
// send the file
// this is the line where the error occurs
reqObj.send(fileToUpload);
Removing the line reqObj.setRequestHeader("Content-Type", "multipart/form-data"); fixed the problem.
Note: this error is shown very differently in other browsers. I.e. Chrome shows something similar to a connection reset which is similar to what Fiddler reports (an empty response due to sudden connection close).
Also, this error appeared only when upload was done from a machine different from WebServer (no problems on localhost).
I just want to add what solved this problem for me, as it is different to all of the above answers.
The ajax calls that were causing the problem were trying to pass an empty data object. It seems IE does not like this, but other browsers don't mind.
To fix it I simply removed data: {}, from the ajax call.
With the Apache 2 change KeepAliveTimeout set it to 60 or above
Upping the directive in the virtualhost for KeepAliveTimeout to 60 solved this for me.
Have encountered the same issue in my asp.net project, in the end i found the issue is with the target function not static, the issue fixed after I put the keyword static.
[WebMethod]
public static List<string> getRawData()
Incase none of these solutions were "clear" enough, essentially IE/Edge is failing to parse your "data" field of your AJAX call properly. More than likely you're sending an "encoded" JSON object.
What Failed:
"data": "{\"Key\":\"Value\"}",
What Works:
"data":'{"Key":"Value"}'
[SOLVED]
I only observed this error today, for me the Error code was different though.
SCRIPT7002: XMLHttpRequest: Network Error 0x2efd, Could not complete
the operation due to error 00002efd.
It was occurring randomly and not all the time. but what it noticed is, if it comes for subsequent ajax calls. so i put some delay of 5 seconds between the ajax calls and it resolved.
The requirement of my application is to navigate to a cross domain page upon logging out. As probably CORS is not set(error: no Access-Control-Allow-Origin header is present) in the cross domain app, hence response.sendRedirect(url) is not working from JAVA side. Now, realizing this cross domain barrier I did some research in UI side, explored many posts in internet and tried the following to navigate to a cross domain page from UI but with no avail. With Angularjs-
$http.jsonp('https://www.google.co.in/');
With JQuery by including jquery.ajax-cross-origin.min.js-
$.ajax({crossOrigin: true,url: 'https://www.google.co.in/'});
In both cases it is giving error: SyntaxError: expected expression, got '<'.
It looks like it is not expecting '<>' tags, but I am expecting it not to return any response (JSON or XML) but to redirect me to some other domain page (ex: https://www.google.co.in/). Can anybody help me resolving this by giving me an workable code which navigates me to a cross domain page (say: https://www.google.co.in/).
instead of $.ajax({crossOrigin: true,url: 'https://www.google.co.in/'}); you have to use window.location.href='https://www.google.co.in/'
window.location.assign('url')
window.location='url'
window.location.href='url'
all of these will work for you
I tested with my below code it is working:
<script>
$.ajax({
type:"POST",
url: 'a.php?id=1',
success:function(d){
if(d){
window.location.href="http://www.google.com";
}
}
});
</script>
Something pretty peculiar is happening with a simple JS GET client. Here's the code using JQuery:
<h3 onclick="$.ajax({
url: 'http://147.102.82.124/',
type: 'GET',
error: function() { alert('FAILURE'); },
success: function() {alert('SUCCESS')}
});">Click me</h3>
The method fires up a 'FAILURE' message unless the url is set to localhost. At the same time, the remote server replies with a 200 status code ( I checked using the web console of Firefox).
[15:06:59.135] GET http://147.102.82.124/ [HTTP/1.1 200 OK 9ms]
And ideas?
As a security measure cross origin requests are not allowed, see CORS
I got the same issue and I solved using a server script which is always able to get the contents of a different domain.
So your ajax request needs to point to your local script (written using Java, PHP, Python or what ever,...) and your local script will be able to provide you the content of different domain.
requrl_1 = "http://www.example.com/index.php";
requrl_2 = "http://www.example.com/redirect.php";
when I request "requrl_1", there is no problem. I'm getting response. "index.php" is not a redirector page.
but requrl_2 is a redirector page, that is redirecting to another website(for example: http://www.cnn.com).
so when I request with XMLHttpRequest, I'm getting exception 101 error.
I must request "redirect.php", there isn't another solution.
How can I do that? Why am I getting "exception 101" error.
I'm coding a Greasemonkey userscript script for google chrome.
It's best to just install Tampermonkey and use it to run your script. Then you can code with GM_xmlhttpRequest()Doc -- which has cross-domain support. And scripts get enhanced capabilities to match what Greasemonkey can do on Firefox.
If you don't want to install Tampermonkey, Chrome userscripts now support cross-site requests via GM_xmlhttpRequest().
So, you could use:
GM_xmlhttpRequest ( {
method: "GET",
url: "http://www.example.com/redirect.php",
onload: function (response) {
//-- Do your business here.
}
} );
From the XMLHttpRequest Spec
If something goes wrong (infinite loop, network errors) the state must
be set to loaded and all members (excluding readyState) of the object
must be set to their initial value. Also, if async is set to false, a
NETWORK_ERR exception must be raised. In addition, all registered
event listeners must be removed.
Basically the redirect is causing the same origin policy to be fired. Which is firing the error. The request should be served with a proxy and not a redirect.
I am building an AJAX application to query an OData endpoint. I've been doing some testing with the Netflix OData feed and found something I don't get:
When I make an .ajax() request to a url (e.g. http://odata.netflix.com/v1/Catalog/Titles) I get the error: "Origin null is not allowed by Access-Control-Allow-Origin". However when I put the same url into my browser the request goes through and I get a response.
What is the fundamental difference here that I'm not getting? How is the browser bypassing the Same Origin Policy?
I also used JSONP for Netflix's OData. It seems to work fine for my application. I have posted the code and explaination under my blog http://bit.ly/95HXLM
Some sample fragment below as well:
49. // Make JSONP call to Netflix
50. $.ajax({
51. dataType: "jsonp",
52. url: query,
53. jsonpCallback: "callback",
54. success: callback
55. });
56. });
57.
58. function callback(result) {
59. // unwrap result
60. var movies = result.d.results;
61.
62. $("#movieTemplateContainer").empty();
63. $("#movieTemplate").tmpl(movies).appendTo("#movieTemplateContainer");
64. }
The same origin policy applies to HTTP requests issued from within code loaded with pages from remote sites. That code is disallowed by the machine from issuing new requests for content from different domains, under the assumption that you, the user in control, were OK with fetching content from haxors.r.us, but you wouldn't want that site to issue HTTP requests to bankofamerica.com without your say-so. However, the browser should allow you, the user in control, to issue HTTP requests to anywhere. Indeed, with Humanity fading in the shadow of the Machine, I demand it. I demand it!
You can make requests to that URL from your server, and then pass along the response to your code on the client (after any sort of filtering or extraction your server code may choose to do). Alternatively, Netflix may support a JSONP API, which would allow your client-side code to issue GET requests as script fetches, with results to be interpreted as Javascript code.
Also it should be noted that this policy has nothing at all to do with jQuery itself. It's a basic security rule on the XMLHttpRequest mechanism.
