How to get an object property value when property name is in a variable?

Question

I need help with a function I've created.

For example, I parse a JSON string and I want to get the value of the passed parameter from the parsed JSON.

function returnVal(name) {
  parsedJSON = JSON.parse('{"test": "hello"}');
  return parseJSON.name;
}

In your snippet you're referring to `parsedJSON.name`, but the only value in your JSON string is `parsedJSON.test` — , Sep 01 '13 at 06:45

Try this:

return parsedJSON[name];

Actually, scratch that. I was the one not reading carefully enough (missed the parameter "name"). I'll remove my comment because I most certainly do not deserver the up-vote on it. – Ingo Bürk Sep 01 '13 at 06:52
