很多文章，都只提供了js部分，包括官方的文档也只有js部分，如果css设置不正确，会导致轮播图不自动播放。

使用的swiper版本：v11.0.3

• https://swiperjs.com/react

实现效果

使用vite创建react应用

pnpm create vite react-app --template react

完整依赖 package.json

App.js

// Import Swiper React components
import { Swiper, SwiperSlide } from "swiper/react";

// import Swiper core and required modules
import { Autoplay } from "swiper/modules";

// import Swiper styles
import "swiper/css";
import "swiper/css/autoplay";

import "./App.css";

// 获取一个随机颜色值
function randomColor() {
  let r = Math.floor(Math.random() * 255);
  let g = Math.floor(Math.random() * 255);
  let b = Math.floor(Math.random() * 255);

  return `rgb(${r},${g},${b})`;
}

// 轮播数据
const list = [
  {
    backgroundColor: randomColor(),
  },
  {
    backgroundColor: randomColor(),
  },
  {
    backgroundColor: randomColor(),
  },
  {
    backgroundColor: randomColor(),
  },
];

function App() {
  return (
    <div className="swiper__wrap">
      <Swiper
        modules={[Autoplay]}
        direction="vertical"
        loop={true}
        slidesPerView={1}
        autoplay={{
          delay: 3000, // ms
        }}
      >
        {list.map((item, index) => {
          return (
            <SwiperSlide>
              <div
                className="swiper__slide"
                style={{ backgroundColor: item.backgroundColor }}
              >
                {index + 1}
              </div>
            </SwiperSlide>
          );
        })}
      </Swiper>
    </div>
  );
}

export default App;

App.css

.swiper__wrap {
  margin: 0 auto;
  margin-top: 200px;
}

.swiper {
  height: 200px;
  width: 300px;
}

.swiper__slide {
  line-height: 200px;
  background-color: pink;
  color: #fff;
  text-align: center;
}

轮播的关键 需要设置swiper容器的尺寸

.swiper {
  height: 200px;
  width: 300px;
}
