mmm... city[0].name
Es parecido a lo que yo queria, pero no es lo que yo quiero, puesto que solo me imprime el resultado de la primera variable, pongo el código completo (aunque es largo y mas de uno pasará de leer :P) a ver si algun alma caritativa es capaz de echarme una mano.

Cuando selecciono con el select la variable cambia, necesito imprimir la variable name, según el nombre de la variable en ese momento.
