添加Bootstrap轮播组件的问题

Question

我正在学习和学习bootstrap，此时我正试图在我的网站上添加一个轮播。

我从Bootstrap中选择了第一个DIV上的一个例子，id =“carouselExampleSlidesOnly”，带有这个ID，旋转木马工作得很好。

但我想删除“carouselExampleSlidesOnly”并更改另一个ID名称。当我这样做改为“myCarousel”时，代码停止工作。

我尝试添加带有ID名称的javascript代码，但即使这样，轮播也不起作用，并显示静态图像。

<script>
$('#myCarousel').carousel({
  interval: 3000,
  pause: null,
})
</script>

   <div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3000" data-pause="null">
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img class="d-block w-100" src="assets/images/slide1.png" alt="First slide">
            <div class="container">
                <div class="slider-text">
                    <h2>Lorem Ipsum is simply dummy text.</h2>
                    <p>ndustry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer.</p>
                </div>

            </div>
        </div>

        <div class="carousel-item">
            <img class="d-block w-100" src="assets/images/slide2.png" alt="Second slide">
            <div class="container">
                <div class="slider-text">
                    <h2>Lorem Ipsum is simply dummy text.</h2>
                    <p>ndustry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer.</p>
                </div>

            </div>
        </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>

我相信你遇到的问题是

$('#myCarousel').carousel({
  interval: 3000,
  pause: null,
})

当您需要字符串或布尔值时，您将null作为参数传递，您可以从控制台中看到此错误。

Chrome上的（Ctrl + shift + I）

它应该是

$('#myCarousel').carousel({
  interval: 3000,
  pause: false,
})

<div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3000" data-pause="null">
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img class="d-block w-100" src="https://via.placeholder.com/150" alt="First slide">
            <div class="container">
                <div class="slider-text">
                    <h2>Lorem Ipsum is simply dummy text.</h2>
                    <p>ndustry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer.</p>
                </div>

            </div>
        </div>

        <div class="carousel-item">
            <img class="d-block w-100" src="https://via.placeholder.com/150" alt="Second slide">
            <div class="container">
                <div class="slider-text">

                </div>

    <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
