javascript - Material.io 标签 : where to put the tab content?

Question

我正在尝试在元素中使用 material.io 选项卡，无论如何 html 结构没有很好的记录:

https://material.io/components/tabs/web#design-api-documentation

<div class="mdc-tab-bar" role="tablist">
  <div class="mdc-tab-scroller">
    <div class="mdc-tab-scroller__scroll-area">
      <div class="mdc-tab-scroller__scroll-content">
        <button class="mdc-tab mdc-tab--active" role="tab" aria-selected="true" tabindex="0">
          <span class="mdc-tab__content">
            <span class="mdc-tab__icon material-icons" aria-hidden="true">favorite</span>
            <span class="mdc-tab__text-label">Favorites</span>
          </span>
          <span class="mdc-tab-indicator mdc-tab-indicator--active">
            <span class="mdc-tab-indicator__content mdc-tab-indicator__content--underline"></span>
          </span>
          <span class="mdc-tab__ripple"></span>
        </button>
      </div>
    </div>
  </div>
</div>

我应该把标签正文内容放在哪里？他们似乎只展示了如何构建标签栏，但没有展示全部功能？

Answer 1

首先，您应该在一个 div 中制作标签栏，然后在另一个 div 中制作内容，另外使用 javascript 来指定何时更改内容。我希望这个答案有所帮助。我想我的答案一定不是很清楚，但是当你浏览代码时你会发现我的意思

<div class="svelte4" style="flex:1;" id="tim">
     <div class="mdc-tab-bar" role="tablist" style="background-color:rgb(34, 34, 34);">
      <div class="mdc-tab-scroller">
        <div class="mdc-tab-scroller__scroll-area">
          <div class="mdc-tab-scroller__scroll-content">
    
            <button class="mdc-tab mdc-tab--active" role="tab" aria-selected="true" tabindex="0">
              <span class="mdc-tab__content">
                <span class="mdc-tab__text-label">1</span>
              </span>
              <span class="mdc-tab-indicator mdc-tab-indicator--active">
                <span class="mdc-tab-indicator__content mdc-tab-indicator__content--underline"></span>
              </span>
              <span class="mdc-tab__ripple"></span>

            <button class="mdc-tab mdc-tab" role="tab" aria-selected="true" tabindex="0">
              <span class="mdc-tab__content">
                <span class="mdc-tab__text-label">2</span>
              </span>
              <span class="mdc-tab-indicator mdc-tab-indicator">
                <span class="mdc-tab-indicator__content mdc-tab-indicator__content--underline"></span>

              <span class="mdc-tab__ripple"></span>
            </button>
    
    
            <button class="mdc-tab mdc-tab" role="tab" aria-selected="true" tabindex="0">
              <span class="mdc-tab__content">
                <span class="mdc-tab__text-label">3</span>
              </span>
              <span class="mdc-tab-indicator mdc-tab-indicator">
                <span class="mdc-tab-indicator__content mdc-tab-indicator__content--underline"></span>
              </span>
              <span class="mdc-tab__ripple"></span>
            </button>
    
    
          
    
    
    
          </div>
        </div>
      </div>
    
    </div>
    
    
    <div class="content content--active">
    <p>1</p>
    </div>
    
    <div class="content">
    <p>2</p>
    </div>
    
    <div class="content"> 
    <p>3</p>
    </div>  
    </div>

var tabBar = new mdc.tabBar.MDCTabBar(document.querySelector('.mdc-tab-bar'));
var contentEls = document.querySelectorAll('.content');

tabBar.listen('MDCTabBar:activated', function (event) {
  // Hide currently-active content
  document.querySelector('.content--active').classList.remove('content--active');
  // Show content for newly-activated tab
  contentEls[event.detail.index].classList.add('content--active');
});
