一个react项目中,在入口文件App.tsx里渲染了<One></One>组件和<Two></Two>组件,在页面中<One/>组件在<Two/>组件上方,<App/>宽400px,<One/>组件宽400px,高200px,<Two/>组件宽400px,高600px,,用swiper怎么只让<One></One>组件变成轮播图,用类组件写,并写出轮播图的css

可以使用 `swiper` 库来实现轮播图,具体实现方法如下:
1. 首先,安装 `swiper` 库:
```
npm install swiper
```
2. 在 `One` 组件中引入 `swiper` 库:
```javascript
import Swiper from 'swiper';
import 'swiper/css/swiper.min.css';
```
3. 在 `One` 组件的 `componentDidMount` 方法中实例化 `swiper`:
```javascript
componentDidMount() {
new Swiper('.swiper-container', {
loop: true,
pagination: {
el: '.swiper-pagination',
clickable: true,
},
});
}
```
4. 在 `One` 组件的 `render` 方法中,使用 `swiper` 的 HTML 结构:
```javascript
render() {
return (
<div className="swiper-container">
<div className="swiper-wrapper">
<div className="swiper-slide">Slide 1</div>
<div className="swiper-slide">Slide 2</div>
<div className="swiper-slide">Slide 3</div>
</div>
<div className="swiper-pagination"></div>
</div>
);
}
```
5. 添加 `swiper` 的 CSS 样式:
```css
.swiper-container {
width: 400px;
height: 200px;
}
.swiper-slide {
text-align: center;
font-size: 18px;
background: #fff;
}
.swiper-pagination-bullet {
width: 10px;
height: 10px;
background: #000;
opacity: 0.5;
}
.swiper-pagination-bullet-active {
opacity: 1;
}
```
6. 最后,需要在 `Two` 组件中删除 `One` 组件的代码,确保 `One` 组件只在 `App` 组件中被渲染一次。
完整代码如下:
```javascript
import React, { Component } from 'react';
import Swiper from 'swiper';
import 'swiper/css/swiper.min.css';
class One extends Component {
componentDidMount() {
new Swiper('.swiper-container', {
loop: true,
pagination: {
el: '.swiper-pagination',
clickable: true,
},
});
}
render() {
return (
<div className="swiper-container">
<div className="swiper-wrapper">
<div className="swiper-slide">Slide 1</div>
<div className="swiper-slide">Slide 2</div>
<div className="swiper-slide">Slide 3</div>
</div>
<div className="swiper-pagination"></div>
</div>
);
}
}
class Two extends Component {
render() {
return (
<div style={{ width: '400px', height: '600px', background: 'gray' }}>
Two
</div>
);
}
}
class App extends Component {
render() {
return (
<div style={{ width: '400px', background: 'blue' }}>
<One />
<Two />
</div>
);
}
}
export default App;
```
