Vérification de la quantité d'espace sharedObject disponible

Question

Je me demande s'il existe un moyen de vérifier la taille limite actuelle sur le disque dur local de l'utilisateur pour sharedObject.

Answer 1

Vous pouvez utiliser la propriété size de SharedObject. Pour autant que je sache, il montre la taille d'un SharedObject spécifique, pas tous, comme je le suppose l'option Paramètres s'affiche. Je pense que 100K est la taille par défaut et l'utilisateur est invité dans le cas où plus d'espace est nécessaire.

Il y a un joli exemple pratique dans la documentation ainsi:
