Bonjour, je dois creer un mini test sur java script, j ai deja les questions mais je n arrive pas a synchroniser le bouton "submit" avec les question dans le but que lorsque je clique dessus je puisse avoir ma reussite en pourcentage, selon si j ai bien repondu aux questions ou non.
Est ce que quelqu un saurait m aider et corriger mes fautes vu mon faible niveau en html ?
merci beaucoup !
