如何在将鼠标悬停在图像上时显示文本

<div class="image-container">
  <img src="image.jpg" alt="图像描述">
  <span class="text">显示的文本</span>
</div>

.image-container {
  position: relative;
  display: inline-block;
}

.text {
  position: absolute;
  top: 100%;
  left: 0;
  visibility: hidden;
  opacity: 0;
  background-color: #000;
  color: #fff;
  padding: 5px;
  transition: opacity 0.3s ease-in-out;
}

.image-container:hover .text {
  visibility: visible;
  opacity: 1;
}

var imageContainer = document.querySelector('.image-container');
var textContainer = document.querySelector('.text');

imageContainer.addEventListener('mouseover', function() {
  var text = generateText(); // 生成文本的函数
  textContainer.innerText = text;
});

imageContainer.addEventListener('mouseout', function() {
  textContainer.innerText = '';
});
