You can use a JavaScript function like below to get the nested properties:

function findProp(obj, key, out) {
    var i,
        proto = Object.prototype,
        ts = proto.toString,
        hasOwn = proto.hasOwnProperty.bind(obj);

    if ('[object Array]' !== ts.call(out)) out = [];

    for (i in obj) {
        if (hasOwn(i)) {
            if (i === key) {
                out.push(obj[i]);
            } else if ('[object Array]' === ts.call(obj[i]) || '[object Object]' === ts.call(obj[i])) {
                findProp(obj[i], key, out);
            }
        }
    }

    return out;
}
