자바스크립트 tab만들기

안녕하세요 찐망고 입니다.

 

js를 이용하여 탭을 만들어 관리해 보겠습니다.

 

 

예전에 많이 썼던 탭형태 js

 

<div class="tabs">
  <button class="tablink" onclick="openTab(event, 'tab1')">Tab 1</button>
  <button class="tablink" onclick="openTab(event, 'tab2')">Tab 2</button>
  <button class="tablink" onclick="openTab(event, 'tab3')">Tab 3</button>

  <div id="tab1" class="tabcontent">
    <h2>Tab 1 Content</h2>
    <p>This is the content of Tab 1.</p>
  </div>

  <div id="tab2" class="tabcontent">
    <h2>Tab 2 Content</h2>
    <p>This is the content of Tab 2.</p>
  </div>

  <div id="tab3" class="tabcontent">
    <h2>Tab 3 Content</h2>
    <p>This is the content of Tab 3.</p>
  </div>
</div>

 

.tabcontent {
  display: none;
}

.tablink {
  background-color: #f2f2f2;
  border: none;
  color: black;
  padding: 10px 20px;
  cursor: pointer;
}

.tablink:hover {
  background-color: #ddd;
}

.tabs {
  overflow: hidden;
  border: 1px solid #ccc;
  background-color: #f9f9f9;
}

 

function openTab(evt, tabName) {
  var i, tabcontent, tablinks;
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  tablinks = document.getElementsByClassName("tablink");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }
  document.getElementById(tabName).style.display = "block";
  evt.currentTarget.className += " active";
}

// Default tab
document.getElementById("tab1").style.display = "block";
document.getElementsByClassName("tablink")[0].className += " active";

 

 

 

 

es6버전도 있지요

<div class="tabs">
  <button class="tablink" data-tab="tab1">Tab 1</button>
  <button class="tablink" data-tab="tab2">Tab 2</button>
  <button class="tablink" data-tab="tab3">Tab 3</button>
</div>

<div id="tab1" class="tabcontent">
  <h2>Tab 1 Content</h2>
  <p>This is the content of Tab 1.</p>
</div>

<div id="tab2" class="tabcontent">
  <h2>Tab 2 Content</h2>
  <p>This is the content of Tab 2.</p>
</div>

<div id="tab3" class="tabcontent">
  <h2>Tab 3 Content</h2>
  <p>This is the content of Tab 3.</p>
</div>

 

const tabLinks = document.querySelectorAll('.tablink');
  const tabContents = document.querySelectorAll('.tabcontent');

  tabLinks.forEach(tabLink => {
    tabLink.addEventListener('click', () => {
      const tabId = tabLink.getAttribute('data-tab');
      
      tabContents.forEach(tabContent => {
        if (tabContent.id === tabId) {
          tabContent.style.display = 'block';
        } else {
          tabContent.style.display = 'none';
        }
      });

      tabLinks.forEach(link => {
        link.classList.remove('active');
      });
      tabLink.classList.add('active');
    });
  });

  // Default tab
  document.getElementById("tab1").style.display = "block";
  tabLinks[0].classList.add('active');

 

 

index를 사용하여 탭을 관리할 수도 있습니다.

<div class="tabs">
  <button class="tablink">Tab 1</button>
  <button class="tablink">Tab 2</button>
  <button class="tablink">Tab 3</button>
</div>

<div id="tab1" class="tabcontent">
  <h2>Tab 1 Content</h2>
  <p>This is the content of Tab 1.</p>
</div>

<div id="tab2" class="tabcontent">
  <h2>Tab 2 Content</h2>
  <p>This is the content of Tab 2.</p>
</div>

<div id="tab3" class="tabcontent">
  <h2>Tab 3 Content</h2>
  <p>This is the content of Tab 3.</p>
</div>

 

const tabLinks = document.querySelectorAll('.tablink');
  const tabContents = document.querySelectorAll('.tabcontent');

  tabLinks.forEach((tabLink, index) => {
    tabLink.addEventListener('click', () => {
      tabContents.forEach((tabContent, i) => {
        if (i === index) {
          tabContent.style.display = 'block';
        } else {
          tabContent.style.display = 'none';
        }
      });

      tabLinks.forEach(link => {
        link.classList.remove('active');
      });
      tabLink.classList.add('active');
    });
  });

  // Default tab
  tabContents[0].style.display = 'block';
  tabLinks[0].classList.add('active');
