Question

I have an object called “message”

“message” holds an anonymous object (as a string):

{"action":"wakeup","hello":"testing123"}
// this is what I get when I output "message" with alert()

How do I address/get the content of “hello” from that?

Answer 1

If message is a string (check it using typeof message === 'string'), you can create an object from it using message = JSON.parse(message). After that you’ll have message.action (value ‘wakeup’) and message.hello (value ‘testing123’) available in message, now being an Object.

If message already is an Object, message.wakeup and message.hello should both be available without conversion.
