salut,
j'aimerais bien lire ce qui est écrit dans une zone de texte d'une page web afin d'afficher ce texte avec animations (scroll) voilà mon code j'ai réussi à afficher quelques formes prédéfinis est ce quelqu'un peut m'aider pour faire animer un texte ecrit dans la zone de texte dans ce serveur web
merci d'avance

salut
j'utilise un formulaire avec la methode GET pour lire les champs de saisie texte :
et je récupère le texte comme tu le fais déjà avec
if (readString.indexOf("?texte=") >0) .... sachant que le texte saisi suit le signe =
merci beaucoup pour votre attention
mais if (readString.indexOf("?texte=") >0) ne me permet pas de récupérer ce qui est écrit dans la zone de texte ! en faite j'ai besoin de récupérer une chaîne de caracactére contenant le message déjà écrit pour l'afficher sur une matrice de LED! le problème c'est que j'arrive pas à récupérer le message écrit dans la zone de texte
