Appel méthode doPost() onclick sur submit
Bonjour ,
Y aurait il un moyen de faire appel à une méthode java suite au submit d'un formulaire ?
Meme si il faudrait passer par du javaScript.
J'ai envie d'afficher le resultat de ma requete dans la meme page que le formulaire par soucis d'ergonomie.
Yaurait il moyen de faire ça ? je joint mon code pour plus de comprehension.
apres le boutton submit , je voudrais afficher le resultat de la requete doPost() ;
Merci pour votre aide
