如何在 Bootstrap 4 轮播中堆叠多个图像

Question

我不知道如何使用 Bootstrap 4，以及如何在一张幻灯片中显示多个小图像（如缩略图），而不是让图像填充轮播的宽度。我用下面的代码尝试了几件事，但仍然无法堆叠很多图像。

<div class="container">
    <h2 class="text-center">- Carousel -</h2><br>

    <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
        <div class="carousel-inner">
            <div class="carousel-item active">
                <img src="http://via.placeholder.com/250x250" alt="First slide">
            </div>
            <div class="carousel-item">
                <img src="http://via.placeholder.com/250x250" alt="Second slide">
            </div>
            <div class="carousel-item">
                <img src="http://via.placeholder.com/250x250" alt="Third slide">
            </div>
            <div class="carousel-item">
                <img src="http://via.placeholder.com/250x250" alt="Fourth slide">
            </div>
            <div class="carousel-item">
                <img src="http://via.placeholder.com/250x250" alt="Fifth slide">
            </div>
            <div class="carousel-item">
                <img src="http://via.placeholder.com/250x250" alt="Sixth slide">
            </div>
        </div>

        <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>
    </div>
</div>

您也可以在轮播幻灯片中使用标准 Bootstrap Grid system 类。因此，您可以使用下面示例中的标记来实现在 example 中看到的行为。
该示例在一张幻灯片中显示五张图片，一旦轮播滑到下一个项目，它将显示下一个五张图片块。

<div id="gallery" class="carousel slide" data-ride="carousel">
    <div class="carousel-inner">
        <div class="carousel-item active">
            <div class="row">
                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/caa8f5/ffffff?text=Image+1" alt="Image 1"/>
                </div>

                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/9984d4/ffffff?text=Image+2" alt="Image 2"/>
                </div>

                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/592e83/ffffff?text=Image+3" alt="Image 3"/>
                </div>

                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/230c33/ffffff?text=Image+4" alt="Image 4"/>
                </div>

                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/b27c66/ffffff?text=Image+5" alt="Image 5"/>
                </div>
            </div>
        </div>

        <div class="carousel-item">
            <div class="row">
                <div class="col">

                <div class="col">

                </div>

                <div class="col">

                </div>

                <div class="col">

                </div>

                <div class="col">

                </div>
            </div>
        </div>
    </div>

    <a class="carousel-control-prev" href="#gallery" role="button" data-slide="prev">

Answer 2

尝试在下一个按钮上触发点击事件。 像这样：

var timer = setInterval(function(){
    $('#nextButton').trigger('click');
 },2000)

点击前一个按钮时不要忘记重置计时器。否则你可能会感觉到一些小故障。
