javascript - JS点击事件监听器没有按预期触发功能

转载作者：太空宇宙更新时间：2023-11-04 07:15:33

我正在尝试将点击事件监听器添加到 div，然后应该更改另一个元素中的 css 样式。我基本上是在尝试制作模型窗口。单击 div/按钮时，它应将显示属性从“无”更改为“边框框”。但是，单击 div 似乎没有任何效果。我已经尝试过控制台日志记录，但那里也没有任何显示。当我移动 div(正在单击)并将其放在 HTML 文档的不同部分时，它似乎工作正常。 super 困惑。

这是 HTML:

最佳答案

边框框不适用于显示属性。正如 David 提到的，border-box 用于调整盒子大小。你的 JS 工作正常，我会把它扔进一个片段给你:

document.querySelector('#modal-btn').addEventListener('click',
  function() {
    console.log('working');
    document.querySelector('.modal').style.display = 'block';
  });

.modal {
  display: none;
}

#modal-btn {
  cursor: pointer;
}

<section class="section-background projects-color">
  <div class="projects-container container">
    <h2 id="projects-section">Projects</h2>
    <div class="section-divider"></div>

    <div class="project">
      <h3>E-commerce Site</h3>
      <div class="project-image project-one"></div>
      <p class="project-description">Lorem ipsum dolor sit amet, pri audire deterruisset ut, mei eu stet diceret pertinacia. Has salutandi mediocritatem te, copiosae disputationi conclusionemque in pro, fugit eleifend argumentum quo et. Sea te quidam instructior complectitur, est vidisse
        consequat deterruisset ex.</p>
      <div class="project-icons">
        <a href="https://github.com/catspacesuits/new-portfolio"><i class="fab fa-github project-btn"></i></a>
        <div class="project-btn" id="modal-btn">More details</div>
        <div class="project-btn">Visit site</div>
      </div>
    </div>
    <div class="modal"></div>
    <!-- Modal window -->
  </div>
  <!-- end of project container -->
</section>

我将 display: border-box 更改为 display: block 和那个函数。我还添加了一个控制台日志，以显示当您单击按钮时它正在触发。
