I have two domains: www.domain1.com and www.domain2.com

I have a plain JSON feed on domain1.

I want to pull the JSON feed from domain1 and put it on a module on domain2.

From what I've read, the way to go about it is by using JSONP but how do you go about doing that? Is there a way to do it with just JQuery/javascript? Or would I have to use server-side code (I'm using Coldfusion). Also could I just use .getJSON and not .ajax (I'm a beginner so I've never used .ajax yet)

EDIT Okay I'm still getting confused. Just adding callback at the end of the url broke it. How could I make it so that instead of a remote path for a feed I am pulling an absolute path where this code is on www.domain2.com but the feed is on www.domain1.com?

var feed ="/event/json.tag/tag/sports/";

$.getJSON(feed,function(data) {

   $.each(data.items, function(i,obj) {

       do something here...
   }        

}

JSONP is just a callback function wrapped around a JSON object. General convention is to have an endpoint that returns JSON, unless a callback parameter is defined on the request, and returns JSONP in that case.

i.e. http://www.domain1.com/api/getStuff might return:

{'foo': 'bar', 'fizz': 'buzz'}

then http://www.domain1.com/api/getStuff?cb=cb123 should return:

cb123({'foo': 'bar', 'fizz': 'buzz'});

I don't know ColdFusion, but I assume this example is good: http://www.coldfusionjedi.com/index.cfm/2009/3/11/Writing-a-JSONP-service-in-ColdFusion

There's no client-only solution unless somebody else already built JSONP support into the server you're working with...
