Code javascript pour récupérer un tableau dans un tableau en retour JSON

bonjour ,

voilà je n'ai pas trouvé comment spécifier la lecture d'un tableau dans un tableau (hormis faire une boucle), mais je souhaitais faire un mapping direct
j'ai un ordre ajax / JSON qui me donne un retour que je map via

Code:

var SEASON = {
                    "td": {
                        "season<-results[0].seasonList": {
                                       "span.SeasonID": function(arg) {
                                                      // log le résultat de SeasonId  
                                        console.log ('season.seasonId:' + season[0].seasonId);

j'ai en retour dans le log couldn't display seasonId of undefined

les data en retours de mon call ajax sont

Code:

....

je vais essayer d'être plus clair ,

j'ai un tableau results [] et dans ce tableau en niveau 1 j'ai un autre tableau seasonList[]
ceci est dans le code retour ajax de mon post (liste brut des data retournées)


je cherche à mapper directement le second tableau via une affectation dynamique dans la variable qui va être remplie
SEASON
par l'instruction "season<-results[0].seasonList"

mais lorsque je fais cela la variable season n'a pas de contenu (lorsque je cherche la valeur de season[0].seasonId le log me retourne 'undefined')

ma question est : ou est mon errur de syntaxe

Remarque :
si je mappe avec "season<-results":
alors la valeur season[0].seasonList[0].seasonId est correcte
