SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3,

Question

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.

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()

Answer 2

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 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.

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!

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>

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(){
  ...
  }
});
