Jquery Ajax call works in all browser except ie 10

Question

The following ajax call works in all browsers except IE10 (unless i set it to IE9 standards mode) I look at it with fiddler and it seems as if the paramater isn't being passed through in ie10 any ideas?

var paramArray = '{"ID":1}';   

 $.ajax({
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        url: '/assets/services/coreWebServices.svc/GetCategoriesWithoutColumns',
        data: paramArray,
        success: successFn,
        error: errorFn
    });

throws the following error

The OperationFormatter could not deserialize any information from the Message because the Message is empty (IsEmpty = true).

Answer 1

This seems to be a bug in jQuery with IE10 (at least the Windows 7 preview release). The POST data does not get sent in the request, I have logged details of the bug to jQuery: http://bugs.jquery.com/ticket/12790#comment:18

UPDATE: In my case it was a bug in Free Download Manager that caused a problem in IE10. They have fixed the issue (3.9.2 build 1281. - Dec 26, 2012) so that it plays nice. If you read the comments in the jQuery link above you can see that someone picked that up too and uninstalling FDM corrected the issue as well. So it's not a problem of IE10 or jQuery, but rather an add-on altering the normal behavior.

Answer 2

In my case, Download Accelerator Plus was the cause. Uninstalling DAP resolved the issue.
