Bootstrap 4.1 轮播指示器

Question

我正在使用 bootstrap 4.1 的最新版本

我正在尝试使用轮播指示器。

但是当我尝试按下我的指标之一时。

它不工作。

我不想使用： “轮播控制上一个” “轮播控制-nextx”

这是我的代码：

<section class="slider">
    <div id="sitebanners" class="carousel slide" data-ride="carousel">
        <ol class="carousel-indicators">
            <li data-target="#sitebanners" data-slide-to="0" class="active"></li>
            <li data-target="#sitebanners" data-slide-to="1" class=""></li>
            <li data-target="#sitebanners" data-slide-to="2" class=""></li>
        </ol>
        <div class="carousel-inner">
            <div class="carousel-item active">
                <img src="images/banner1.jpg" alt="First slide"/>
                <div class="carousel-caption">

                </div>
            </div>
            <div class="carousel-item">

                <div class="carousel-caption">

</section>

我尝试了很多方法。

但没有任何效果

谢谢！

您的代码似乎是正确的。我在包装器周围添加了一些填充，并给它一个深色背景，但除此之外它与您的代码相同。下面的示例显示了它的工作原理，因此您的代码中的其他地方肯定有其他东西干扰了您的指标函数。

不想听起来很滑稽，但是您是否包含了 Bootstrap JS 文件？
