jQuery Ajax call No element found issue

Question

I am getting a javascript error on firefox 3.5, when trying to call an ajax method.

Please find the error below:

XML Parsing Error: no element found          


        

Answer 1

I've come across an alternative cause of this - might help someone.

If you make a $.ajax request (in my case a PUT request) that returns a 200 header but no body content I've seen this same XML Parsing error message occur - even when the dataType is set to json.

(At least) two solutions work:

• Make all API PUT requests return some content, or
• Return a 204 'No Content' header instead (what I ended up doing)
