Question

This will be tuff because I don’t really know how to ask the right question. So, I have an object with the following structure:

When I do:

console.info(myObject.StackPaneProvider)

I get the expected result:

But if I try to access it dynamically with

var key = "StackPaneProvider";
console.info(myObj.key); 

(actually the key variable is generated dynamically, and it is of type string) I get “undefined” in Firebug. Why?

Answer 1

var key = "StackPaneProvider";
console.info(myObj[key]);

You want to use [key] for example

myObj.StackPaneProvider === myObj["StackPaneProvider"];
myObj.key === myObj["key"]
