this question has answer here:

• accessing nested javascript objects string key 25 answers

is possible define "path" object key?

for instance if have object:

var obj = {     hello: {         you: "you"     } } 

i select this:

var path = "hello.you"; obj[path]; //should return "you" 

(doesn't work obviously, there way?)

you can try this:

var path = "hello.you"; eval("obj."+path);
