Re^3: Perl json parser and JSONP issue

"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" }
[download]

Here's an example JSONP file:

process({ "name": "Joe Bloggs" });
[download]

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.

Well you are right... it`s kind of confusing... So if I am right, every time I create and record a JSON, I have to convert it to JSONP with wrapping it with the function before calling it back...	[reply]

Typically you'd configure your web server (or some other piece of middleware) to convert your JSON to JSONP on the fly. I'm surprised there isn't an Apache mod_jsonp that I can point you towards. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]

Thank you. Your help is most appreciated. It was enough :) I`ve understand it. However it`s kind of confusing to me that JSONP stuff... By the way... can`t I just have a js file with a plain `var Obj = { foo: function() {return me;}, data: "str", id: 0x8888 };` can`t tell what`s the big fuss of JSON.	[reply] [d/l]
