You can do this easily using just the API: JS_ValueToString(cx, id). 
Then use JS_GetStringChars to get the value of the JSString.

Mozilla guys strongly prefer people to restrict themselves to the API. 
Chances are good you can do whatever you need through it, and it's much 
easier to give assistance.
