CHAPITRE 13 : L’objet global « window » :
L’objet global window est le conteneur de toutes les propriétés et fonc-
tions globales et d’accès direct, c’est-à-dire accessibles sans le préfixe
« window. »
Pour obtenir les noms de toutes les propriétés propres d’un objet (ses
propres méthodes = fonctions), qui n’appartiennent pas à son prototype,
on utilise la méthode getOwnPropertyNames() de l’objet Object.
Voici les 812 propriétés [et méthodes = fonctions] que ça donne à la
console du navigateur Opéra pour l’objet [global] window.
C’est comme un catalogue quand on veut utiliser une propriété de cet
objet global window ou simplement connaître les propriétés globales
disponibles.
Object.getOwnPropertyNames(window)
