I need transform array to json

Question

I have a array of objects like this in php:

Array
(
    [0] => Array
        (
            [id] => 1
            [text] => aa
        )

    [1] => Array
        (
            [id] => 2
            [text] => valladolid
        )

    [2] => Array
        (
            [id] => 3
            [text] => valencia
        )

)

I use json_encode to convert array in php to javascript

var data = '{{listCountries|json_encode|raw}}';

And this, they transform in:

var data = '[{"id":1,"text":"aa"},{"id":2,"text":"valladolid"},{"id":3,"text":"valencia"}]';

And i need, without single-quotes:

var data = [{"id":1,"text":"aa"},{"id":2,"text":"valladolid"},{"id":3,"text":"valencia"}];

Answer 1

JavaScript will receive your perfectly encoded JSON in String format, You have to DECODE/PARSE it

JSON.parse(YOUR_STRING); // native JavaScript JSON parser, supported in major wab browsers
jQuery.parseJSON();      // for JQuery

...

Answer 2

var data = JSON.parse('{{listCountries|json_encode|raw}}')

EDIT: paste that into your php template and you should be good to go! Credit goes to @Andreas for finding it first.
