  您可以使用mouseenter和mouseout执行相同的操作 .

  $(document).ready(function () {
  
      $('.carousel-caption').hide();
      $('img[alt = imgAlt]').mouseenter(function () {
          $('.carousel-caption').show();
      }).mouseout(function(){
          $('.carousel-caption').hide();
      });
  });

  可能由于选择器语法不正确，用于访问图像的选择器不返回任何内容 . 见Attribute Selectors - jQuery

  您可以通过在控制台中打印出来轻松找到它：

  console.log($('img[alt = imgAlt'));
  

  尝试按以下方式访问图像：

  $('img[alt="imgAlt"').on('hover', function () {
      $('.carousel-caption').fadeIn();
  });

  对于一个纯粹的css替代方案，当你将鼠标悬停在 .carousel-inner 上时，你可以将 Headers 淡入淡出：

  .carousel-caption{
    opacity:0;
    transition:500ms ease-in-out;
  }
  .carousel-item:hover .carousel-caption{
    opacity:1;
  }

  请关注此 . 我希望你能得到你的解决方案 . 并按照Bootstrap 4 Carousel页面进行操作 . https://getbootstrap.com/docs/4.1/components/carousel/

  .carousel-caption {
    opacity: 0;
    -webkit-transition: all 0.4s;
    transition: all 0.4s;
    color: #fff;
  }
  
  .carousel-item:hover .carousel-caption {
    opacity: 1;
  }
