 // ajouter() = add() // supprimer() = delete() // afficher() = print() function ajouter() { let fullName = document.getElementById("name").value; let mail = document.getElementById("email").value; myList = []; myList.push({ name: fullName, email: mail }) document.getElementById("list").innerHTML += '<option>' + fullName + '</option>' + '<br>'; } function supprimer() { let del = document.getElementById("list"); del.remove(del.selectedIndex); } // function afficher(){ // let show = document.getElementById("list") // let showName = myList[show.selectedIndex].name, // showEmail = myList[show.selectedIndex].email; // alert("Hello " + showName + " Your email is : " + showEmail); // }
 <form action=""> <br><br> <label for="name">Full name : <input id="name" type="text"></label><br><br> <label for="email">Email : <input id="email" type="email"></label><br><br><br> <button type="button" onclick="ajouter()">Ajouter</button> <button type="button" onclick="supprimer()">Supprimer</button> <button type="button" onclick="afficher()">Afficher l'addresse</button> <br><br> <select name="names-list" id="list" size="5" style="width: 200px;"> </select> </form>

Debe mover myList = [] fuera de las funciones

Aquí hay una versión completamente funcional.

Descomente las partes con localStorage para guardar la lista

 const myListString = null// localStorage.getItem("list"); const myList = myListString ? JSON.parse(myListString) : []; const list = document.getElementById("list"); function ajouter() { let fullName = document.getElementById("name").value; let mail = document.getElementById("email").value; myList.push({ name: fullName, email: mail }) list.add(new Option(fullName)); // localStorage.setItem("list", JSON.stringify(myList)) } function supprimer() { const fullName = document.getElementById("name").value; const idx = myList.findIndex(item => item.name === fullName) if (idx !=-1) { myList.splice(idx,1) list.options[idx].remove() } } function afficher() { const idx = list.selectedIndex; const person = myList[idx] alert("Hello " + person.name + " Your email is : " + person.email); }
 <form action=""> <br><br> <label for="name">Full name : <input id="name" type="text"></label><br><br> <label for="email">Email : <input id="email" type="email"></label><br><br><br> <button type="button" onclick="ajouter()">Ajouter</button> <button type="button" onclick="supprimer()">Supprimer</button> <button type="button" onclick="afficher()">Afficher l'addresse</button> <br><br> <select name="names-list" id="list" size="5" style="width: 200px;"> </select> </form>
