Why is this JSONP invalid?

I'm looking to access some data with jQuery but I've had some trouble with this and when I checked the JSONP data I was trying to access from an API it says that it is invalid JSON. Why is that? Is this something normal? A JSONP data always returns invalid in a JSON validator? Here is the data.

Hey Jose,

Seems valid to me, what makes you think it's invalid? The JSON Formatter and Validator here says it's valid..

Hi Jose,

http://jsonlint.com/ seems to agree that your object is valid JSON. I had to copy inside the 'response' parentheses..

But doesn't JSONP need a parsing callback??

Take care,

But does it always need a callback? The API I'm using has a link specially for JSONP, do I need the callback here too? I thought it was only necessary to tell the server that we want JSONP format?

Hi Jose,

That's a good question.. JSONP is "wrapped" and requires a callback function call to unpack the JSON data. But I do not know if jQuery takes care of that unpacking and just hands you JSON.

It would help to have wider context: Your example code, how you set up the request, what badge and video you're working on, etc. The rest of us are sort of newbies too, and so it would help to have your code to play around with.

Thanks!

You know, Jose, it might be interesting to set up the JSONP request and response handling outside jQuery..??

What do you think?
