J'aimerais ajouter 2 colonnes supplémentaires dans le 1er tableau et les variables associées sont commentées dans le fichier html fourni.

Code:

1
2
3
 
//res['dtg'] = ;
//res['brg'] = ;

Pour ce qui est de la création des colonnes, pas de soucis j'ai capté.

Concernant le code à exécuter pour obtenir les valeurs, je l'ai fais et il est fonctionnel je l'ai testé sur JSFiddle, le voici :

// Fonction conversion de Degrées <=> Radians
function deg2rad (angle) {
    return angle * (Math.PI /180);
}
 
function rad2deg (angle) {
		return angle * (180 / Math.PI);
}
// Rayon équatorial de la Terre en nm
var ray = 3443.9; 
 
// Conversion des coordonnées de Degrées en Radians
var lat1 = deg2rad(lat_b);
var lon1 = deg2rad(lon_b);
var lat2 = deg2rad(lat_f);
var lon2 = deg2rad(lon_f);
 
// Formules :
// dtg = acos(sin(lat1)*sin(lat2)+cos(lat1)*cos(lat2)*cos(lon1-lon2))
var dtg = (Math.round ( Math.acos( Math.sin(lat1) * Math.sin(lat2) + Math.cos(lat1) * Math.cos(lat2) * Math.cos(lon1-lon2) ) * ray ) );
 
// brg = atan(1/(((tan(lat2)*cos(lat1)-sin(lat1)*cos(lon1-lon2))/sin(lon1-lon2))))
var brg =Math.round( Math.abs( rad2deg( Math.atan( 1 /( ( ( Math.tan(lat2) * Math.cos(lat1) - Math.sin(lat1) * Math.cos(lon1 - lon2)) / Math.sin(lon1 - lon2) ) ) ) ) ) );

Voici le fichier html ou j'obtiens "NaN"

Mon souci réside dans l'intégration de ce code dans mon fichier html ... J'ai beau chercher, modifier j'obtiens toujours soit "Undefined" soit "NaN" ... :weird:

Si quelqu'un peut m'aiguiller ça serait cool parce que la je tourne en rond.
Merci
