JavaScript изменяет неправильный элемент и не применяется к желаемому элементу

Question

Я новичок в этом, поэтому, пожалуйста, извините за мое непонимание. Я редактировал ручку из CodePen и застрял. Я продублировал и изменил карточку базового профиля, чтобы на ней было две карточки. Это JavaScript, которое меняет то, что представлено на карте. Я не могу понять, как использовать функцию JS на дублированной карте. При нажатии кнопок на второй карточке изменяется представление первой карточки. Я хочу знать, что мне нужно изменить в JS, чтобы добиться этого. Я поискал в Интернете и не смог найти решения. Надеюсь, здесь кто-нибудь сможет помочь.

const buttons = document.querySelectorAll(".card-buttons button");
const sections = document.querySelectorAll(".card-section");
const card = document.querySelector(".card");

const handleButtonClick = (e) => {
  const targetSection = e.target.getAttribute("data-section");
  const section = document.querySelector(targetSection);
  targetSection !== "#about"
    ? card.classList.add("is-active")
    : card.classList.remove("is-active");
  card.setAttribute("data-state", targetSection);
  sections.forEach((s) => s.classList.remove("is-active"));
  buttons.forEach((b) => b.classList.remove("is-active"));
  e.target.classList.add("is-active");
  section.classList.add("is-active");
};

buttons.forEach((btn) => {
  btn.addEventListener("click", handleButtonClick);
});

var elements = document.getElementsByClassName("card");
  for(var i = 0; i < elements.length; i++)
    {
      elements[i].onclick = function(){

        // remove class from sibling

        var el = elements[0];
        while(el)
        {
          if(el.tagName === "DIV"){
            //remove class
            el.classList.remove("is-active");                   
          }
          // pass to the new sibling
          el = el.nextSibling;
        }

        this.classList.add("is-active");  
      };
    }

Answer 1

Прежде всего, вы используете идентификатор для каждого раздела в карточках, и они дублируются, помните, что идентификаторы должны быть уникальными. Самый простой способ справиться с этим - переместить идентификатор в набор данных, например:

Исходный: <div class="card-section" id="about">
Изменить на: <div class="card-section" data-id="about">

Вы получаете только первую карточку в глобальной области const card = document.querySelector(".card");, но вам нужно получить карту, на которой нажата кнопка, принадлежит:

  // Find the card
  const card = e.target.closest(".card");

Теперь вы можете получить targetSection и искать раздел для активации по его идентификатору, хранящемуся в наборе данных:

  const targetSection = e.target.getAttribute("data-section");
  // Then find the section by searching for dataset id atribute
  const section = card.querySelector(`[data-id='${targetSection}']`);

Удалить # из:

• Javascript targetSection !== "#about"
• CSS правил .card[data-state="#about"], то же для опыт и контакт
• HTML кнопки <button data-section="#about">ABOUT</button>, то же самое для опыт и контакт

Обновление: Чтобы закрыть «неактивные» карты, удаления класса is-active недостаточно, потому что у вас есть стили для `[data-state = 'some-value'], поэтому, удалите это значение, чтобы оно заработало.

const buttons = document.querySelectorAll(".card-buttons button");
const sections = document.querySelectorAll(".card-section");
// Get all cards
const cards = document.querySelectorAll(".card");

const handleButtonClick = (e) => {
  // First close all the cards
  cards.forEach((c) => {
      c.classList.remove('is-active');
      c.dataset.state = '';
  });
  // I've moved these 2 lines here from below
  sections.forEach((s) => s.classList.remove("is-active"));
  buttons.forEach((b) => b.classList.remove("is-active"));

// Find the card
  const card = e.target.closest(".card");
  const targetSection = e.target.getAttribute("data-section");
  // Then find the section
  const section = card.querySelector(`[data-id='${targetSection}']`);
  targetSection !== "about"
    ? card.classList.add("is-active")
    : card.classList.remove("is-active");
  card.setAttribute("data-state", targetSection);
