Abstract

La présente invention concerne un procédé et un appareil de chargement de données de nœuds DOM, ainsi qu'un dispositif informatique et un support de stockage. Une consommation excessive de ressources de réseau est évitée en mettant en cache par étapes des nœuds DOM d'une région de page faisant l'objet d'une opération. Un utilisateur opère sur une région particulière d'une page et met en cache un nœud DOM dans la région considérée, vers lequel des données doivent être chargées; lorsque l'opération est répétée, il n'est pas indispensable d'explorer à nouveau une structure arborescente de DOM à la recherche d'un nœud DOM, et comme il existe des nœuds DOM multiples dans la structure arborescente de DOM, l'invention évite un gaspillage de ressources causé par la recherche, parmi les nœuds DOM multiples, du nœud DOM correspondant à la région; de plus, le blocage de la page causé par un gaspillage de ressources dû à la mise en cache à une seule reprise des nœuds DOM de la page entière est également évité.
