using jQuery jQuery.getJSON():

 $.getJSON('ajax/test.json', function(data) {
     console.log(data); //see your data ( works in Chrome / FF with firebug)
     console.log(data["Restoration"][0]["easy"]["value"]) //should output 1
 });

This is an alternative to use "jQuery.getJSON()" because sometimes we don't have a "domain/file.json" or somewhere to do the $get or we don't want to use jQuery for this simple process.

This method parses json from string.

You can do it with simple javascript like this:

//json string for testing
var jsonstr = '{"id":"743222825", "name":"Oscar Jara"}';

//parse json
var data = JSON.parse(jsonstr);

//print in console
console.log("My name is: " + data.name + " and my id is: " + data.id);

Hope this helps.

Regards.

You didn't try to run the code yourself, did you? JSON.parse throws an error because the value you pass is not a string.

@FelixKling Yes, you were right, I missed the quotes, thanks for pointing this out (I've updated the post).

Oh wow, I didn't realize this question was from 2012. Sorry, I would have just edited the answer myself instead of leaving an half-snarky comment :-/

@FelixKling No problem, it's ok.
