基础用法

通过autoplay属性设置自动轮播间隔

<van-swipe :autoplay="3000" indicator-color="white">
  <van-swipe-item>1</van-swipe-item>
  <van-swipe-item>2</van-swipe-item>
  <van-swipe-item>3</van-swipe-item>
  <van-swipe-item>4</van-swipe-item>
</van-swipe>

图片懒加载

配合 Lazyload 组件实现图片懒加载

<van-swipe :autoplay="3000">
  <van-swipe-item v-for="(image, index) in images" :key="index">
    <img v-lazy="image" />
  </van-swipe-item>
</van-swipe>

export default {
  data() {
    return {
      images: [
        'https://img.yzcdn.cn/1.jpg',
        'https://img.yzcdn.cn/2.jpg'
      ]
    }
  }
}

监听 change 事件

<van-swipe @change="onChange">
  <van-swipe-item>1</van-swipe-item>
  <van-swipe-item>2</van-swipe-item>
  <van-swipe-item>3</van-swipe-item>
  <van-swipe-item>4</van-swipe-item>
</van-swipe>

export default {
  methods: {
    onChange(index) {
      Toast('当前 Swipe 索引：' + index);
    }
  }
}

纵向滚动

<van-swipe :autoplay="3000" vertical>
  <van-swipe-item>1</van-swipe-item>
  <van-swipe-item>2</van-swipe-item>
  <van-swipe-item>3</van-swipe-item>
  <van-swipe-item>4</van-swipe-item>
</van-swipe>

控制滑块大小

<van-swipe :autoplay="3000" :width="300">
  <van-swipe-item>1</van-swipe-item>
  <van-swipe-item>2</van-swipe-item>
  <van-swipe-item>3</van-swipe-item>
  <van-swipe-item>4</van-swipe-item>
</van-swipe>

自定义指示器

<van-swipe @change="onChange">
  <van-swipe-item>1</van-swipe-item>
  <van-swipe-item>2</van-swipe-item>
  <van-swipe-item>3</van-swipe-item>
  <van-swipe-item>4</van-swipe-item>
  <div class="custom-indicator" slot="indicator">
    {{ current + 1 }}/4
  </div>
</van-swipe>

export default {
  data() {
    return {
      current: 0
    }
  },
  methods: {
    onChange(index) {
      this.current = index;
    }
  }
}
