I am trying to access some stuff on my newly created couchone.com database. I just want to learn how to fetch the names of the databases I have created using an ajax call from a client browser running on a local pc. Using jQuery (in Firexox) in the firebug command window I run this: test = function(){ url = "http://withforesight.couchone.com/_all_dbs"; $.ajax({ url: url, dataType: 'jsonp', success: ( function(Response){ console.log(26, 'response is: ', Response) } ), error: function(XMLHttpRequest, textStatus, errorThrown){alert("Error"); } }); }; test() I receive the following reply from the server: HTTP/1.1 200 OK Server: CouchDB/1.0.2 (Erlang OTP/R14B) Date: Sun, 30 Jan 2011 22:52:29 GMT Content-Type: text/plain;charset=utf-8 Content-Length: 55 Cache-Control: must-revalidate In all cases I see a status code of 200OK. (note odd content type). However: (1) the success handler DOES NOT trigger. Nothing appears in the console log. (2) In the NET tab I see the data *has been* returned both in JSON format and as an array (under the RESPONSE tab) ["test_suite_reports","test_suite_db","mike","_users"] (3) I see no way [?]to access the returned data in my program. It is not in the DOM and there is no variable I can find that contains the response data. Now if I change the ajax dataType request to just json dataType: 'jsonp', to dataType: 'json', then: (1) the success handler fires (2) BUT NO is data returned (3) and I get this in response headers HTTP/1.1 200 OK Server: CouchDB/1.0.2 (Erlang OTP/R14B) Date: Sun, 30 Jan 2011 22:55:05 GMT Content-Type: application/json Content-Length: 55 Cache-Control: must-revalidate I think jsonP is required because this seems to be a cross-domain request. But either I am missing something or perhaps CouchDB is not setup to handle the callback processing required by jsonp requests. (see: http://remysharp.com/2007/10/08/what-is-jsonp/) Any help, advice, beer appreciated.... Also, I can not find any examples or documentation for: jquery.couch.js (the jQ plugin) and couch.js (that ships with the couchDB installation). Pointers to docs/examples much appreciated.
