Getting specific value from JSON using javascript

Question

I am using ajax to get a small set of data back from the server which returns JSON data with the following format:

{
    \"data\": [
        {
            \"         


        

Answer 1

You could take a functional approach and use the Array.filter method:

var matchingResults = JSON['data'].filter(function(x){ return x.id == 2; });
// procede to use matching elements...

Answer 2

If you parse it into a javascript object using something like jQuery's json parse method, you could just reference the various items in the array like a normal javascript array.

Do it like this:

var dataArray = $.parseJSON(myJson).data;

var theFirstData = dataArray[0]; //get the data with id "1"

Alternately, if you don't want to use jQuery, you can use JSON.parse(jsonToParse). Here're the docs for that method.
