Parse json encoded array and fetch values

Question

How to parse these JSon array am getting from json_encode(arr), the output is:

[{"id":"44","data":"[[10],[27],[13]]","_types":"ff"},  {"id":"44","data":"[[140],[327],[213]]","_types":"44f"}]

I need to iterate this using java script and fetch each values. Am getting an error, Unexpected token.

If json.parse() doesnt work, please show us your code where you try to fetch — Bidoubiwa

Your question is not specific enough. What do you want to do (example)? — IsraGab

You are getting a string, you simply need to do JSON.parse

var str = '[{"id":"44","data":"[[10],[27],[13]]","_types":"ff"},  {"id":"44","data":"[[140],[327],[213]]","_types":"44f"}]';

var obj = JSON.parse( str );

alert( obj[0].id );

there is no single codes in my json_enode($arr) output.Am getting this error Uncaught TypeError: Cannot use 'in' operator when i tried this

@user263371 my code doesn't have any in operator. I wonder why got the error you got. Can you share a fiddle? Or can you update the OP to show the code that you have tried?

the code you have provided is working, but the json assigned to str is in single codes right?my json output doesnt has single codes i cannot apply json.parse to str..

You are getting array of java script object,i think you don't need to parse this.Just iterate this and fetch the result like below.

var q = [{"id":"44","data":"[[10],[27],[13]]","_types":"ff"},  {"id":"44","data":"[[140],[327],[213]]","_types":"44f"}];

 q.forEach(function(i){console.log(i.id)});
