    array_obj = JS_NewArrayObject(cx, 0, NULL);
    for (i = 0; i < len; i++)
        JS_DefineElement(cx, array_obj, i, values[i], NULL, NULL, 
JSPROP_ENUMERATE);
    JS_DefineProperty(cx, parent_obj, "my_array", 
OBJECT_TO_JSVAL(array_obj), NULL, NULL, JSPROP_ENUMERATE);

Don't forget to root array_obj, e.g., by setting *rval = 
OBJECT_TO_JSVAL(array_obj) before the loop.
