Bonjour,

Je suis entrain de créer un distancier à l'aide de l'api JS fourni par viamichelin.

Voici le code de ma page :

Le problème c'est que lorsque j'ouvre ma page http://distancier.webuda.com/
j'ai droit au message "2 consecutive steps are identicals therefore route computation failed".
Je ne comprends pas. Je n'ai pas modifié grand chose de l'exemple http://dev.viamichelin.fr/web/api-ja...emples-v2#iti2.
Je sature et j'aurais besoin d'un coup d'oeil extérieur pour me rendre compte de la boulette.
Merci

A tout hasard l'API n'attendrait pas du numérique pour les latitudes et longitudes ? Ce qui pourrait expliquer qu'il trouve deux points de coordonnées identiques ...

Quand je regarde les exemples de code :

Code:

coords : {lon: 2.24414, lat: 48.83514},

Code:

subsidiaries.push({coords: {lon: 9.18587, lat: 45.46306}, htm : "Milano"});

il me semble bien que les cordonnées doivent être fournies en numérique et non en string comme tu le fais :

Code:

{htm:"BG",lon:"05.270804",lat:"45.798583"},

Merci pour la réponse. Elle m'a mise sur la voie.
Voilà le code fonctionnel de mon distancier :
