How to select data from this json using jQuery?

Question

var tz = {"US": [123, 456, 784], "UK": [456, 461, 953]};

An I get country code from web page's form.

e.g.

var countryCode = $('#country option:selected').val(); // Now "countryCode" is UK

Now I want to get the array data of "UK". e.g. [456, 461, 953]

How can I write the code? Thanks.

tz does not contain JSON data. It is a normal object literal. It is only JSON if it is a string (and only contains valid data types of course). — Felix Kling

Since you have the value in a variable, use the bracket notation:

tz[countryCode]

or if you know the value beforehand, this should work too.

tz.UK

For anyone that is looking for the answer of the question in the title:

If you actually have JSON data:

var tz = '{"US": [123, 456, 784], "UK": [456, 461, 953]};';

Then you use the parseJSON method to turn it into a Javascript object, then you can access the object:

var countryData = $.parseJSON(tz);
var countryArray = countryData[countryCode];
