实现滑动功能的方法

在React中实现滑动功能可以通过多种方式完成，包括使用原生CSS、第三方库或自定义钩子。以下是几种常见的实现方法。

使用CSS实现滑动

通过CSS的overflow和scroll属性可以快速实现滑动效果。这种方法适合简单的滑动需求。

import React from 'react';
import './Slider.css';

const Slider = () => {
  return (
    <div className="slider-container">
      <div className="slider-content">
        {/* 滑动内容 */}
        <div className="item">Item 1</div>
        <div className="item">Item 2</div>
        <div className="item">Item 3</div>
      </div>
    </div>
  );
};

export default Slider;

对应的CSS文件：

.slider-container {
  width: 100%;
  overflow-x: auto;
  white-space: nowrap;
}

.slider-content {
  display: inline-block;
}

.item {
  display: inline-block;
  width: 200px;
  height: 200px;
  margin: 0 10px;
  background: #f0f0f0;
}

使用第三方库（如react-slick）

react-slick是一个流行的轮播库，支持滑动、自动播放等功能。

安装依赖：

npm install react-slick slick-carousel

示例代码：

import React from 'react';
import Slider from 'react-slick';
import 'slick-carousel/slick/slick.css';
import 'slick-carousel/slick/slick-theme.css';

const SimpleSlider = () => {
  const settings = {
    dots: true,
    infinite: true,
    speed: 500,
    slidesToShow: 1,
    slidesToScroll: 1
  };

  return (
    <Slider {...settings}>
      <div>
        <h3>Slide 1</h3>
      </div>
      <div>
        <h3>Slide 2</h3>
      </div>
      <div>
        <h3>Slide 3</h3>
      </div>
    </Slider>
  );
};

export default SimpleSlider;

自定义滑动钩子（useSwipe）

通过自定义钩子可以实现更灵活的滑动逻辑，例如手势滑动。

import { useState, useRef, useEffect } from 'react';

const useSwipe = (ref) => {
  const [startX, setStartX] = useState(0);
  const [scrollLeft, setScrollLeft] = useState(0);

  useEffect(() => {
    const slider = ref.current;

    const handleMouseDown = (e) => {
      setStartX(e.pageX - slider.offsetLeft);
      setScrollLeft(slider.scrollLeft);
    };

    const handleMouseMove = (e) => {
      const x = e.pageX - slider.offsetLeft;
      const walk = (x - startX) * 2;
      slider.scrollLeft = scrollLeft - walk;
    };

    slider.addEventListener('mousedown', handleMouseDown);
    slider.addEventListener('mousemove', handleMouseMove);

    return () => {
      slider.removeEventListener('mousedown', handleMouseDown);
      slider.removeEventListener('mousemove', handleMouseMove);
    };
  }, [ref, startX, scrollLeft]);

  return ref;
};

const SwipeSlider = () => {
  const sliderRef = useRef(null);
  useSwipe(sliderRef);

  return (
    <div ref={sliderRef} className="swipe-slider">
      <div className="swipe-item">Item 1</div>
      <div className="swipe-item">Item 2</div>
      <div className="swipe-item">Item 3</div>
    </div>
  );
};

export default SwipeSlider;

对应的CSS：

.swipe-slider {
  display: flex;
  overflow-x: auto;
  cursor: grab;
  user-select: none;
}

.swipe-item {
  flex: 0 0 auto;
  width: 200px;
  height: 200px;
  margin: 0 10px;
  background: #f0f0f0;
}

使用React Spring实现动画滑动

react-spring可以用于实现平滑的滑动动画效果。

安装依赖：

npm install react-spring

示例代码：

import React, { useState } from 'react';
import { useSpring, animated } from 'react-spring';

const SpringSlider = () => {
  const [index, setIndex] = useState(0);
  const slides = ['Slide 1', 'Slide 2', 'Slide 3'];

  const props = useSpring({
    opacity: 1,
    transform: `translate3d(${-index * 100}%, 0, 0)`,
    from: { opacity: 0, transform: 'translate3d(100%, 0, 0)' },
  });

  return (
    <div className="spring-slider">
      <animated.div style={props} className="slide">
        {slides[index]}
      </animated.div>
      <button onClick={() => setIndex((i) => (i + 1) % slides.length)}>
        Next
      </button>
    </div>
  );
};

export default SpringSlider;

对应的CSS：

.spring-slider {
  position: relative;
  width: 100%;
  height: 200px;
  overflow: hidden;
}

.slide {
  position: absolute;
  width: 100%;
  height: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
  background: #f0f0f0;
}
