vue实现图片滑动

Vue 实现图片滑动功能

使用第三方库（如 Swiper）

安装 Swiper 库：

npm install swiper

在 Vue 组件中引入 Swiper：

<template>
  <div class="swiper-container">
    <div class="swiper-wrapper">
      <div class="swiper-slide" v-for="(image, index) in images" :key="index">
        <img :src="image" alt="Slide">
      </div>
    </div>
    <div class="swiper-pagination"></div>
    <div class="swiper-button-next"></div>
    <div class="swiper-button-prev"></div>
  </div>
</template>

<script>
import Swiper from 'swiper';
import 'swiper/swiper-bundle.css';

export default {
  data() {
    return {
      images: [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ]
    };
  },
  mounted() {
    new Swiper('.swiper-container', {
      loop: true,
      pagination: {
        el: '.swiper-pagination',
        clickable: true,
      },
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
      },
    });
  }
};
</script>

<style scoped>
.swiper-container {
  width: 100%;
  height: 300px;
}
.swiper-slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
</style>

手动实现图片滑动

通过 Vue 的响应式数据和 CSS 过渡效果实现：

<template>
  <div class="slider-container">
    <div class="slider" :style="{ transform: `translateX(-${currentIndex * 100}%)` }">
      <div class="slide" v-for="(image, index) in images" :key="index">
        <img :src="image" alt="Slide">
      </div>
    </div>
    <button @click="prev">Previous</button>
    <button @click="next">Next</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      images: [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ],
      currentIndex: 0
    };
  },
  methods: {
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.images.length) % this.images.length;
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.images.length;
    }
  }
};
</script>

<style scoped>
.slider-container {
  width: 100%;
  height: 300px;
  overflow: hidden;
  position: relative;
}
.slider {
  display: flex;
  transition: transform 0.5s ease;
}
.slide {
  min-width: 100%;
}
.slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
</style>

添加触摸事件支持

扩展手动实现方案以支持触摸滑动：

<template>
  <div 
    class="slider-container"
    @touchstart="handleTouchStart"
    @touchmove="handleTouchMove"
    @touchend="handleTouchEnd"
  >
    <div class="slider" :style="{ transform: `translateX(-${currentIndex * 100}%)` }">
      <div class="slide" v-for="(image, index) in images" :key="index">
        <img :src="image" alt="Slide">
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      images: [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ],
      currentIndex: 0,
      touchStartX: 0,
      touchEndX: 0
    };
  },
  methods: {
    handleTouchStart(e) {
      this.touchStartX = e.changedTouches[0].screenX;
    },
    handleTouchMove(e) {
      this.touchEndX = e.changedTouches[0].screenX;
    },
    handleTouchEnd() {
      if (this.touchStartX - this.touchEndX > 50) {
        this.next();
      }
      if (this.touchEndX - this.touchStartX > 50) {
        this.prev();
      }
    },
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.images.length) % this.images.length;
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.images.length;
    }
  }
};
</script>

自动轮播功能

为手动实现方案添加自动轮播：

<script>
export default {
  data() {
    return {
      images: [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ],
      currentIndex: 0,
      interval: null
    };
  },
  mounted() {
    this.startAutoPlay();
  },
  beforeDestroy() {
    this.stopAutoPlay();
  },
  methods: {
    startAutoPlay() {
      this.interval = setInterval(() => {
        this.next();
      }, 3000);
    },
    stopAutoPlay() {
      clearInterval(this.interval);
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.images.length;
    }
  }
};
</script>
