j'ai un bouton sur mon html:Comment éviter le modèle thymeleaf peut ne pas exister lors de l'appel d'une méthode sur le contrôleur en utilisant Ajax?
<button id="btnSave"
type="button"
name="formAction"
onclick="saveAddWorkItem();"
value="save"
class="btn btn-default">Save Ajax</button>
Et sur mon javascript je ceci:
function saveAddWorkItem(){
const params = $("form").serialize();
$.ajax({
type: "POST",
url: "/nonInstructionalWorkload/saveAjax",
data: params,
success: function (data) {
alert("Saved Work Item");
}
});
}
qu'il appelle correctement la méthode sur le contrôleur:
def saveAjax(){
println("Save Ajax")
println("Params Save Ajax: " + params)
}
Mais mon problème est, une fois qu'il exécute le contrôleur, je m'attendais à revenir au message "élément de travail enregistré" sur le côté js.
Je m'attends à essayer de sauvegarder l'élément, et s'il y a une erreur de validation, etc. il devrait revenir à la js avec ses messages, champs avec erreur, etc afin que nous puissions le gérer et afficher le message l'utilisateur.
Mais au lieu que je reçois cette erreur:

Il n'y a pas de page saveAjax sur mes modèles. Et je n'en ai pas besoin, j'en ai juste besoin pour revenir à la fonction js. Je ne peux pas voir ce que je fais mal ici.
Merci! J'ai été capable de le faire fonctionner en utilisant le rendu retournant un JSON. – Igor
