JSON to associative array in jquery

Question

I read more here, but I have not found the answer to my problem My problem:

I have (from php via ajax return json string)

str = '[{"id":"159","pavadinimas":"Building B","_id":"200",.................}]';

this is JSON string and I do obj = $.parseJSON(str); i can take any value in that way like alert(obj[0]._id) I get 200.

But how I can get associative array from json like:

dataArray = [
"id":"159",
"pavadinimas":"Building B",
"_id":"200",
...
]

I want get value 200 like that

val = dataArray['_id'];

Answer 1

There is no associative array concept in javascript, but only object.

var arr = $.parseJSON(str);
var obj = arr[0];
var _id = obj['_id']

Answer 2

Javascript does not have associative arrays. You will have to use objects, which use curly brackets {} instead.

dataObj = {
    "id":"159",
    "pavadinimas":"Building B",
    "_id":"200",
    ...
}

console.log( dataobj.id );
console.log( dataobj['id'] );

Both works the same.

So for your example, you can access the object the way you would expect an associative array to work.
