Getting specific value from JSON using javascript
Solution 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...
Solution 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.

I am using ajax to get a small set of data back from the server which returns JSON data with the following format:
{ "data": [ { "id": "1", "value": "One" }, { "id": "2", "value": "Two" }, { "id": "3", "value": "Three" } ] }
On the client side, this is assigned to a variable named
response
. I useresponse.data
to get the contents.The question is, is there an easier way to get the value without doing a loop? I'm kinda looking for something like this
response[id==2].value
which should give me "Two".I'm open for any suggestions if this is not possible.
