"You can clearly see that I am passing a JSON file to a callback function"

Yes - that's entirely the problem. Your function expects to be get JSONP, and it's being given JSON. As I said: JSON and JSONP are different file formats.

You script is trying to get some JSONP from http://localhost/dat.json?callback=dbg but it's being given JSON. JSON and JSONP are different file formats.

Here's an example JSON file:

{ "name": "Joe Bloggs" }

Here's an example JSONP file:

process({ "name": "Joe Bloggs" });

As you can see, they look a little bit different. That's because JSON and JSONP are different file formats.

Also, make sure you're sending the correct HTTP headers.

  • For JSON, you want Content-Type: application/json.
  • For JSONP, you want Content-Type: application/ecmascript or Content-Type: application/javascript or Content-Type: text/javascript.

Note the difference: that's because JSON and JSONP are different file formats.
