移动卡片

创建一个在悬停时移动的卡片。

  • .container元素上设置适当的perspective以实现移动效果。
  • .card元素的transform属性添加过渡效果。
  • 使用Document.querySelector()选择.card元素,并为mousemovemouseout事件添加事件监听器。
  • 使用Element.getBoundingClientRect()获取.card元素的xywidthheight
  • 计算相对距离作为xy轴上的值,范围为-11,并通过transform属性应用它。
<div class="container">
  <div class="shifting-card">
    <div class="content">
      <h3>卡片</h3>

const card = document.querySelector('.shifting-card');

const cy = y + height / 2;

const handleMove = e => {
  const { pageX, pageY } = e;
  const dx = (cx - pageX) / (width / 2);
  const dy = (cy - pageY) / (height / 2);
  e.target.style.transform =
    `rotateX(${10 * dy * -1}deg) rotateY(${10 * dx}deg)`;
};

const handleOut = e => {
  e.target.style.transform = 'initial';
};

card.addEventListener('mousemove', handleMove);
card.addEventListener('mouseout', handleOut);

card.addEventListener('mousemove', handleMove); // 当鼠标在card元素上移动时,触发handleMove函数 card.addEventListener('mouseout', handleOut); // 当鼠标移出card元素时,触发handleOut函数
