XML et API Google map

**Mikkle** · 19/02/2010, 10h23

Bonjour,

Le problème rencontré concerne l'affichage partiel de marqueurs sur google map.

J'ai une base de données mysql qui regroupe 6 sites et leurs coordonnées géographiques en décimal. Sur les 6, seulement 4 s'affiche dans google map...pourquoi ?

Je n'arrive pas à trouver le paramètre bloquant.

Quelqu'un peut-il m'aider ?

Merci d'avance.

Voici le script de la page html :

J'ai trouvé. J'avais simplement mis des virgules à la place des points dans les coordonnées décimales de la base.

Par contre, comment afficher la carte google map dans un cadre html. En utilisant le code suivant, elle n'apparait plus...pourquoi ?
