Réécriture du titre : impossible de réagir à la fonction Somme

Question

J'ai activé la fonctionnalité OnClick à l'aide de JavaScript. Mais lors du processus final, c'est-à-dire la sommation, le code que j'ai inséré n'a pas réagi.

Y a-t-il quelque chose que j'ai manqué ? Je pense que c'est correct, peut-être que mon insertion de code est erronée...

Merci d'avoir pris le temps de lire et de répondre à mes questions.

Answer 1

Utilisez d'abord le journal de la console pour vérifier votre valeur, puis consolez également la somme, puis poussez-la vers le champ de saisie de la somme. Pour autant que je sache, votre code fonctionne bien et s'exécute sur mon ordinateur au format HTML brut. Vous avez peut-être sélectionné le mauvais identifiant, veuillez vérifier.
