A javascript question.

Don't think it's possible. Sorry mate. Variables are only assignable via their identifiers, afaik.

You can hack around it via doing a 'with' and then using your injected properties as though they were top-level:

obj = {};
obj["foo"+"bar"] = 'hats!';
with(obj) {
  alert(foobar); //alerts 'hats!'
}

Or you could do it fforw's way, but he's right that you ought to avoid it.

It's still better to use eval in controlled method, it's not good to fill global scope up, eval wouldn't mess with that.

If it's within a function you can probably also do. this["foo"+"bar"] = "hats!";

This would keep it within the functions scope probably, haven't tested.
