javascript - 如何让这个轮播每 'defined' 秒更换一次图像？

Question

我希望输出每 3 秒更改一次图像。我不知道如何修改现有的输出。我找不到要编辑的适当属性。

carousel-item:after {
  content: "";
  display: block;
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.1);
}

.carousel-inner img {
  width: 100%;
  height: 100%;
}

<section class="container-fluid px-0">

You can use this I think

$('.carousel').carousel({
  interval: 1000 * 10
});

或

<div id="myCarousel" class="carousel slide" data-interval="1000" data-ride="carousel">
