Javascript Objects and keys

Question

The following command shows the properties of an Object.

var keys = Object.keys(result);

Output: [requester.client.id,request.id]

When I try to print an alert(result[request.id]) or alert(result.request.id) I dont get the values. Is there something I am missing?

@RokoC.Buljan Yes; as far as I can tell, the OP here appears to have properties named requester.client.id and request.id (i.e., the property names have period characters in them). — apsillers

Instead of alert, try your browser's developer console. You can inspect objects, set breakpoints and perform other useful debugging operations. — outis

@apsillers Yes, I got it now after a second look, anyway... seems to me that something is wrong down there... — Roko C. Buljan

In JavaScript objects keys are strings, though they can have periods. What you probably getting as the output is ['requester.client.id','request.id'], so it should be accessed as result['requester.client.id'].

Your result object has properties named "requester.client.id" and "request.id".

You need to do alert(result["request.id"]).

result[request.id] does not work because request here is treated as a variable name, and you probably have no variable named request.

result.request.id is closer, but it also fails because the property name has a period in it, so the parser treats this as the the id property of the request property of result.
