I will like to read a JSON file (kind of like a webservice running on a server) and process it using JavaScript.
I was wondering if anyone will be able to point me to some good example, tutorials or sample code?
Much appreciated.

The answers I found on Google all lead to parsing a JSON string in a var. But what if my var is a URI? Eg. var JSON_URL = "abc.com/data.json"user1079950– user10799502012-11-11 04:26:05 +00:00Commented Nov 11, 2012 at 4:26

3This are two independent problems: Getting the data and parsing it. You have to Ajax to load the JSON file. If file is from an external domain, you have to use a proxy or JSONP if supported by the server (but that's not JSON anymore, despite its name).Felix Kling– Felix Kling2012-11-11 04:27:10 +00:00Commented Nov 11, 2012 at 4:27

You can use jQuery's $.getJSON function. See the jQuery documentation

I'm not sure if I understand your question entirely, but if you have a string accessible in your JS, you can call JSON.parse(yourString) which will return a JS object representation of the string. This should work in all modern browsers.

Nope. I am looking to do a JSON.parse(URI). Eg. var JSON_URL = "abc.com/data.json"

Ah, gotcha. In this case, you can do as Felix commented above on your initial question -- make an AJAX request to your server, read the text response and then call JSON.parse. If this is not your server, then you may have cross-domain issues -- can you clarify your use case a little bit more?
