VisualizaçõesMostrar el precio seleccionado del elemento del cuadro desplegable de la API
que quiero lograr??
Quiero mostrar el precio de cada artículo seleccionado del cuadro desplegable usando API. Traté de usar el evento de clic, pero es demasiado difícil para mí en este momento, ya que soy un principiante. ¿Alguien puede ayudarme a mostrar el precio del artículo seleccionado en el cuadro desplegable en un lapso en la esquina inferior izquierda del formulario cuando seleccionamos una opción?
const apiData =[ { "id":"1", "question" :"Love", "price":"90" }, { "id":2, "question":"Carrer", "price":"80" }, { "id":"3", "question":"Shadi", "price":"100" }, { "id":"4", "question":"Future", "price":"200" }, { "id":"5", "question":"Office", "price":"300" }, { "id":"6", "question":"After-Life", "price":"400" } ] //Js Code for diplaying items in drop box (working prefectly fine) async function loadUsers() { //const response = await fetch("../reference_json/questions_API.js"); //return response.json(); return apiData } document.addEventListener("DOMContentLoaded", async () => { try { const users = await loadUsers(); const divContainer = document.getElementById('question'); users.forEach(user => { const paragraphElem = document.createElement('option'); paragraphElem.innerText = `${user.question}`; divContainer.appendChild(paragraphElem); }); } catch (e) { console.log('ERROR'); console.log(e); } }); <form class ="choose-form"> <div class="mb-3"> <select class="form-select" id ="question"> <option>Select a category : Love,carrer,more ...</option> </select> </div> <nav class="navbar navbar-expand-lg navbar-light"> <span> ₹99(including GST)</span> <span>Ideas what to ask</span> <div class="profile-icon" style="justify-content-end"> <button type="submit" class="btn btn-warning">Ask a Question </button> </div> </nav> </form>

dado que está llamando datos desde ajax, debe guardar todos los valores necesarios mientras los carga desde el servidor, luego onchange un evento de cambio en el elemento seleccionado y luego imprimir el valor de la opción seleccionada en su intervalo
aquí está el código corregido a continuación
const apiData =[ { "id":"1", "question" :"Love", "price":"90" }, { "id":2, "question":"Carrer", "price":"80" }, { "id":"3", "question":"Shadi", "price":"100" }, { "id":"4", "question":"Future", "price":"200" }, { "id":"5", "question":"Office", "price":"300" }, { "id":"6", "question":"After-Life", "price":"400" } ] //Js Code for diplaying items in drop box (working prefectly fine) async function loadUsers() { //const response = await fetch("../reference_json/questions_API.js"); //return response.json(); return apiData } document.addEventListener("DOMContentLoaded", async () => { try { const users = await loadUsers(); const divContainer = document.getElementById('question'); users.forEach(user => { const paragraphElem = document.createElement('option'); paragraphElem.innerText = `${user.question}`; // edited line saving matching data to option paragraphElem.data = user divContainer.appendChild(paragraphElem); }); } catch (e) { console.log('ERROR'); console.log(e); } }); // edited line var select = document.querySelector("#question"), priceEl = document.querySelector(".priceShow") select.onchange = function(){ var selected = select[select.selectedIndex], value = typeof selected.data != "undefined" ? selected.data.price:null if(value){priceEl.innerText = `₹${value}(including GST)`} } <form class ="choose-form"> <div class="mb-3"> <select class="form-select" id ="question"> <option>Select a category : Love,carrer,more ...</option> </select> </div> <nav class="navbar navbar-expand-lg navbar-light"> <!-- edited line --> <span class="priceShow"> ₹99(including GST)</span> <span>Ideas what to ask</span> <div class="profile-icon" style="justify-content-end"> <button type="submit" class="btn btn-warning">Ask a Question </button> </div> </nav> </form>
