Convert JSON array into individual JS variables

rated 0 times [ 27] [ 1] / answers: 1 / hits: 5681 / 11 Years ago, fri, january 24, 2014, 12:00:00

I have a JSON array:

{a:apple,b:banana,c:carrot}

I want to split each part of the array into seperate variables, ie,

a = apple,

b = banana;

c = carrot;

I have googled my goggles off but can't seem to find a correct way to do this. I am new to JSON and have done a fair bit of reading but what I am after doesn't seem to be referenced within my grasp.

EDIT: There seems to be confusion as to whether my array is a string or object. I am receiving a response from PHP as follows:

$json = array(

    'a' =>  $a,

    'b'     =>  $b,

    'c' =>  $c,

    );

    echo json_encode($json);

My JS code is as follows:

var data = ajax.responseText;

data = JSON.parse(data);

I get {a:apple,b:banana,c:carrot} as a result of

json.stringify(data);

One example of how you can do this is found here.

It assumes you want to put the variables into global scope. If this is the case, this will work:

function extract(variable) {

    for (var key in variable) {

        window[key] = variable[key];

    }

}



var obj = {a:apple,b:banana,c:carrot}



extract(obj);



alert(a);

alert(b);

alert(c);
