I am pulling JSON cross domain and for some reason I keep getting a parseerror returned:

HTTP Error:Error: jQuery17209875996995251626_1343943259805 was not called

I am able to see the data just fine on the page - and the callback looks like this:

callback:jQuery17209875996995251626_1343943259805_:1343943260015

Please help me to diagnose what I am missing - thanks!

var data = $.parseJSON(data);

Since you are doing a JSONP request, you will get an object literal passed into the callback function. You can't use parseJSON on that. Anyway, jQuery is intelligent and always does the parse for you if the content-type is known.

Not sure whether that triggers the error message, but to the question jQuery JSON response always triggers a ParseError this was the solution.

OK, that's simple. Look at the script it loads: That is no valid JSONP - it misses the callback padding. Also, the mime-type is wrong: For a JSONP script, it should be text/javascript or application/javascript, for the JSON they deliver it should be application/json.

jQuery does detect the load of the "script", but as nothing gets executed it throws an the error that "the given callback was not called although the file was successfully loaded" - parseerror suspected.

Are you sure that the webservice supports JSONP at all?
