将自举轮播项目设置为具有最大高度的元素

问题描述

我正在将具有不同长度文本的内容动态加载到Bootstrap Carousel组件中。为了防止父容器随每个轮播项目的装载而跳高，我想确定所有项目的最大高度并将其设置为最大高度。这样一来，我就可以使用填充等方式处理布局，而页面上的其他弹性项目不会四处移动。

 <div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
        <img src="..." class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="..." class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="..." class="d-block w-100" alt="...">
    </div>
  </div>
</div>

<script>
    $(document).ready(function () {
        //set all carousel items to the highest container
        var containers = document.getElementsByClassName('carousel-item');
        var max_height = 0;

        //find highest container
        for (var i = 0; i < containers.length; i++) {
            var container_height = containers[i].offsetHeight;
            if (container_height > max_height) {
                max_height = container_height;               
            }
        }

        //set container heights
        for (var i = 0; i < containers.length; i++) {
            containers[i].offsetHeight = max_height;
        }
    });
</script>

这是行不通的，因为唯一显示的容器高度> 0。有没有一种方法可以模拟这些容器的高度，而无需实际显示它们？

解决方法

这与您的问题类似。我想您可以从中得到一个主意。

import Table from "@material-ui/core/Table";
import TableBody from "@material-ui/core/TableBody";

                    </TableRow>
                  ))}
                </TableBody>

        );
      }
    }
    export default Wish;
