Question

这个家伙对我来说还很新...我尝试使自定义引导程序自动更改幻灯片。我在这里https://getbootstrap.com/docs/4.3/components/carousel/遵循文档，但是我找不到我做错了什么。手动转过幻灯片，但我无法按间隔更改 https://codepen.io/Ale3andr0s/pen/ExYPWgQ#=

Ι按照我的说明遵循了文档。我导入了bootstrap.js和jquery.js，但是幻灯片在自动间隔上仍然没有变化。我也用

$('.carousel').carousel({
  interval: 10
});

和

$(document).ready(function() {
    $('.carousel').carousel({
      interval: 10
    })
  });

HTML：

<div class="slider carousel slide" data-ride="carousel">
  <input type="radio" name="slider" title="slide1" checked="checked" class="slider__nav active"/>
  <input type="radio" name="slider" title="slide2" class="slider__nav"/>
  <input type="radio" name="slider" title="slide3" class="slider__nav"/>
  <input type="radio" name="slider" title="slide4" class="slider__nav"/>

  <div class="slider__inner data-interval=100">

    <div class="slider__contents active"><i class="slider__image fa fa-codepen"></i>
      <h2 class="slider__caption">codepen</h2>
      <p class="slider__txt">Lorem ipsum dolor sit amet, consectetur adipisicing elit. At cupiditate omnis possimus illo quos, corporis minima!</p>

    </div>

    <div class="slider__contents"><i class="slider__image fa fa-diamond"></i>
      <h2 class="slider__caption">diamond</h2>
      <p class="slider__txt">Lorem ipsum dolor sit amet, consectetur adipisicing elit. At cupiditate omnis possimus illo quos, corporis minima!</p>

JS：

$('.carousel').carousel({

});

$(document).ready(function() {
    $('.carousel').carousel({
      interval: 10

  });

旋转木马应该自动旋转幻灯片，但是不会。
