Ajax et l'autocomplétion

Bonjour à tous,

Je suis ici pour rechercher un pue d'aide à la résolution d'un petit problème qui je suis sûr est simple pour quelqu'un qui connait bien le javascript.

J'ai un scriptd'auto-complétion que j'ai trouvé sur le web et je souhaiterais le modifier afin qu'au clique il insert 2 informations différente au lieu d'une.

Exemple recherche de ville par code postal :

je tape 75013, le script va chercher en BDD 75013 qui correspond à PARIS 13, jusque là tout va bien.

Mais au clique, il insert dans l'input seulement le code postal et non la ville qui est dans une colonne différente de la même table.

Voici mon script 'completer.js' :

Code:
