I made it that way:

if I have:

var jsonArg1 = new Object();
    jsonArg1.name = 'calc this';
    jsonArg1.value = 3.1415;
var jsonArg2 = new Object();
    jsonArg2.name = 'calc this again';
    jsonArg2.value = 2.73;

var pluginArrayArg = new Array();
    pluginArrayArg.push(jsonArg1);
    pluginArrayArg.push(jsonArg2);

to convert pluginArrayArg (which is pure javascript array) into JSON array:

var jsonArray = JSON.parse(JSON.stringify(pluginArrayArg))

If you have a well-formed JSON string, you should be able to do

var as = JSON.parse(jstring);

I do this all the time when transfering arrays through AJAX.

Is this what you are loking for ? You can map on your array and just extract the role attribute of each datum.

const jsonString = ...
const data = JSON.parse(jsonString).map(data => data.role);
console.log(JSON.stringify(data, null, 2));

JSON uses double quotes to delimit strings and field names.

Hi. Please can you help with the following. My PHP returns back the following json:

{"outcome":"Case saved","id":"140"}

I basically want to convert this into an array. I’ve tried parsing it as:

JSON.parse(result)

and this returns:

 Object { outcome="Case saved",  id="140"}

But how do I then convert this into an array?

My original PHP code, btw, is:

$result = array(
                "outcome" => "Case saved",
                "id" => $new_case_id
        );
        $json=  json_encode($result);
        return $json;

Many thanks

As simple as that.

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
 dataObj = JSON.parse(str);
