How can I use PHP array or json response in javascript?

Question

let me show you my flow briefly.

when I am calling an Ajax from the index.phtml file the ajax returns me this response.

Array
(
    [Data] => Array
        (
            [0] => Array
                (
                    [PlayerId] => 201503261611120312176355026
                    [PlayerName] => Leonel Messi
                    [PlayerPossition] => Striker
                    [PlayerPrice] => 15
                    [PlayerNationality] => Argentina
                    [ImageUrl] => messi.jpg
                )

            [1] => Array
                (
                    [PlayerId] => 2015040711252904291525683176
                    [PlayerName] => Simon Mignolet
                    [PlayerPossition] => Goalkeeper
                    [PlayerPrice] => 12
                    [PlayerNationality] => Belgium
                    [ImageUrl] => Mignolet.jpg
                )

            [2] => Array
                (
                    [PlayerId] => 201503301517200320707502096
                    [PlayerName] => Petr Cech
                    [PlayerPossition] => Goalkeeper
                    [PlayerPrice] => 10
                    [PlayerNationality] => czech Republic
                    [ImageUrl] => Petr.jpg
                )
)

This is because of When I am calling an API it is giving me the json string like this and I am decoding it so we will get the above out put.

{"Data":[{"PlayerId":"201503261611120312176355026","PlayerName":"Leonel Messi","PlayerPossition":"Striker","PlayerPrice":"15","PlayerNationality":"Argentina","ImageUrl":"messi.jpg"},
         {"PlayerId":"2015040711252904291525683176","PlayerName":"Simon Mignolet","PlayerPossition":"Goalkeeper","PlayerPrice":"12","PlayerNationality":"Belgium","ImageUrl":"Mignolet.jpg"},
         {"PlayerId":"201503301517200320707502096","PlayerName":"Petr Cech","PlayerPossition":"Goalkeeper","PlayerPrice":"10","PlayerNationality":"czech Republic","ImageUrl":"Petr.jpg"}]
}

Finally what is my questions are.

I want to use the response of API in javascript as array so,I am doing json_decode on the string coming from the api,I should decode the string or ket as it is as a json String for further use in javascript?if yes then how can I use the json string in javascript as array?

if no then how can I use the PHP array that I have shown above in javascript as array.?

Help is needed! It just need the guidance that how to use it, i have seen manny question on this topic but not getting it properly.

This is the full response..

This is the errorImage..

enter image description here

My js

$(document).ready(function () {
                        $.ajax({
                            url: '/home/getPlayers',
                            success: function (data) {
                                showPlayers(data);
                            }

                        });

                        function showPlayers(data) {

                            console.log(data);
                            data = JSON.parse(data);

                            console.log(data);
                        }
                    });

if you want that JSON string used by your javascript, then you don't really need to decode it at all — Kevin

so how can i use that json string as an array I have tried with data.Data,data['Data'] where datais var and 'Data is the first key'.but its not working — Bhavik Joshi

Have a look on Article: api.jquery.com/jquery.parsejson it take json string and parse it into array than you can run a look on that array values. — Iffi
– Iffi, Commented May 11, 2015 at 6:30
after doing JSON.parse(json); I am doing data.Data[0]it is giving me the object but the problem is an error Uncaught SyntaxError: Unexpected token u what can be reason behind that? — Bhavik Joshi

get your JavaScript variable with

var obj = {"Data":[{"PlayerId":"201503261611120312176355026","PlayerName":"Leonel Messi","PlayerPossition":"Striker","PlayerPrice":"15","PlayerNationality":"Argentina","ImageUrl":"messi.jpg"},{"PlayerId":"2015040711252904291525683176","PlayerName":"Simon Mignolet","PlayerPossition":"Goalkeeper","PlayerPrice":"12","PlayerNationality":"Belgium","ImageUrl":"Mignolet.jpg"},{"PlayerId":"201503301517200320707502096","PlayerName":"Petr Cech","PlayerPossition":"Goalkeeper","PlayerPrice":"10","PlayerNationality":"czech Republic","ImageUrl":"Petr.jpg"}]}

Now you can access the elements like this for example:

obj.Data[0].PlayerId

To parse or create JSON strings, there are these two functions:

JSON.parse()
JSON.strigify()

You can use JSON.parse(json); to convert it into object, the use that object! :)

Here's a demo to show you what it returns: http://jsfiddle.net/Lekmnxzb/
