Bonjour,

J'essaie de programmer un sudoku sur un site internet mais je désire que ce sudoku soit à chaque fois le même quand on charge la page.
Pour le moment j'ai le code ci-dessous. Le problème c'est que avec ce code bin cela me crée à chaque fois un sudoku différent. Est-ce que quelqu'un pourrait m'aider à transformer ce code pour que le sudoku reste le même ?

Merci d'avance

Bonjour
Si tu veux qu'il reste identique.... il faut retirer le random.

Bonjour

Il ne faut pas retirer le random, sinon plus rien ne marche.
Il faut le remplacer par une fonction qui redonne toujours la même liste de nombres (pseudo-) aléatoires.
Personnellement, pour faire la même chose, j'utilise la fonction Mash qu'on trouve dans ce site :
https://www.grc.com/otg/uheprng.htm
En changeant la 'graine' du générateur, tu peux obtenir d'autres séries de nombres aléatoires et donc d'autres parties de sudoku, toutes reproductibles si tu prends note de la graine utilisée.

Ou encore mieux implémenter la sauvegarde des grilles et leur chargement. Cela peut-être fait facilement avec des cookies ou localStorage.

et tu mettrais ça comment dans le code?

implémenter = ajouter
où mettre quoi? comment ?

Pour sauvegarder il faut que les valeurs existent, donc mettre ça après la création de données.
Pour charger il faut vérifier qu'il y ait bien une sauvegarde donc au lancement du programme à priori.
...ça c'est pour le code mais il faut bien sûr implémenter le bouton sauvegarder où le faire à chaque tour du joueur(quand il rajoute une réponse);le quoi et le comment c'est à vous de le définir. éventuellement renseignez vous sur la sérialisation et les formats comme JSon.

Mais ce que j'aurais bien voulu c'est en fait que le sudoku soit le même pour toute personne qui ouvre la page internet pas uniquement lorsque que l'on recharge la page

Tu recopies la fonction Mash au début de ton javascript : 
/* extrait de uheprng.js, script de génération de nombres aléatoires de haute qualité
  (uhe= Ultra High Entropy) trouvé sur le site https://www.grc.com/otg/uheprng.htm
*/

/* ============================================================================
 This is based upon Johannes Baagoe's carefully designed and efficient hash
 function for use with JavaScript.  It has a proven "avalanche" effect such
 that every bit of the input affects every bit of the output 50% of the time,
 which is good. See: http://baagoe.com/en/RandomMusings/hash/avalanche.xhtml
 ============================================================================
*/
function Mash() {
 var n = 0xefc8249d;
 var mash = function(data) {
  if ( data ) {
   data = data.toString();
   for (var i = 0; i < data.length; i++) {
    n += data.charCodeAt(i);
    var h = 0.02519603282416938 * n;
    n = h >>> 0;
    h -= n;
    h *= n;
    n = h >>> 0;
    h -= n;
    n += h * 0x100000000; // 2^32
   }
   return (n >>> 0) * 2.3283064365386963e-10; // 2^-32
  } else n = 0xefc8249d;
 };
  return mash;
}

Puis tu redéfinis la fonction Math.random pour qu'elle utilise mash : 
  Math.random = (function(graine){
    let mash=Mash();               // récupère une instance
    return ()=> mash(graine);
  })('a10');


Tu peux mettre ce que tu veux à la place du 'a10' : c'est la graine dont je parlais.

Tu n'as pas à modifier le reste de ton script.

Je n'ai pas essayé, car sans le CSS ton sudoku ne marche pas - en tous cas ne ressemble pas à un sudoku.
