J'ai écrit un bon de commande et n'ai pas de probleme dans les calculs mis à part pour les frais d'expedition. Toujours j'ai la meme reponse dans la case prevue: NaN.
Je voudrais que si le total >= 15 euros les frais = 00 euro et si inferieur les frais =2.60 euros.
Voici une partie du script:
<SCRIPT language=JavaScript>
 
function AjouteVirgule(nombre)
{
var AvecVirgule = "";
var num = "" + Math.round(nombre*100);
if (num.length == 0) {AvecVirgule += "0.00";}
else if (num.length == 1) {AvecVirgule += "0.0" + num;}
else if (num.length == 2 && num > 0) {AvecVirgule += "0." + num;}
else if (num.length == 2 && num < 0) {AvecVirgule += "-"+Math.abs(num/100);}
else
{AvecVirgule += num.substring(0, num.length - 2);
AvecVirgule += ".";
AvecVirgule += num.substring(num.length - 2, num.length);}
return AvecVirgule;
}
