Hi!
You cannot set metadata.detail using the return value of citifmonlineDetail
function.
You must:
var metadata = {
// initialize, skipping detail
};
// then set the detail using the callback
citifmonlineDetail(link, function (result) {
metadata.detail = result;
// then in this callback, you can use the console
console.log("----");
console.log(metadata); // or console.dir(metadata) or
console.log(JSON.stringify(metadata, null, 4)
});
