Carousel

EmblaGitHub
一个使用 Embla 构建的带动画和滑动的轮播。

用法

使用走马灯组件在走马灯中显示项目列表。

<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel v-slot="{ item }" :items="items" class="w-full max-w-xs mx-auto">
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>
在桌面端，您可以用鼠标水平拖动走马灯。

项

使用数组形式的 items prop，并使用默认插槽渲染每个项目

<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel v-slot="{ item }" :items="items" class="w-full max-w-xs mx-auto">
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>

您还可以传入一个包含以下属性的对象数组

  • class?: any
  • ui?: { item?: ClassNameValue }

您可以通过使用以下内容控制可见的项目数量basis / width在 item 上的实用类

<script setup lang="ts">
const items = [
  'https://picsum.photos/468/468?random=1',
  'https://picsum.photos/468/468?random=2',
  'https://picsum.photos/468/468?random=3',
  'https://picsum.photos/468/468?random=4',
  'https://picsum.photos/468/468?random=5',
  'https://picsum.photos/468/468?random=6'
]
</script>

<template>
  <UCarousel v-slot="{ item }" :items="items" :ui="{ item: 'basis-1/3' }">
    <img :src="item" width="234" height="234" class="rounded-lg">
  </UCarousel>
</template>

Orientation

使用 orientation prop 更改进度条的方向。默认为 horizontal。

在桌面端，您可以用鼠标垂直拖动走马灯。
<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel
    v-slot="{ item }"
    orientation="vertical"
    :items="items"
    :ui="{ container: 'h-[336px]' }"
    class="w-full max-w-xs mx-auto"
  >
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>
在垂直方向上，您需要为容器指定一个 height。

箭头

使用 arrows prop 显示上一个和下一个按钮。

<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel v-slot="{ item }" arrows :items="items" class="w-full max-w-xs mx-auto">
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>

上一个 / 下一个

使用 prev 和 next prop，通过任何 Button prop 自定义上一个和下一个按钮。

<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel
    v-slot="{ item }"
    arrows
    :prev="{ color: 'primary' }"
    :next="{ variant: 'solid' }"
    :items="items"
    class="w-full max-w-xs mx-auto"
  >
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>

上一个/下一个图标

使用 prev-icon 和 next-icon prop 自定义按钮 Icon。默认为 i-lucide-arrow-left / i-lucide-arrow-right。

<script setup lang="ts">
defineProps<{
  prevIcon?: string
  nextIcon?: string
}>()

const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel
    v-slot="{ item }"
    arrows
    :prev-icon="prevIcon"
    :next-icon="nextIcon"
    :items="items"
    class="w-full max-w-xs mx-auto"
  >
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>
您可以在 app.config.ts 文件中通过 ui.icons.arrowLeft / ui.icons.arrowRight 键全局自定义这些图标。
您可以在 vite.config.ts 文件中通过 ui.icons.arrowLeft / ui.icons.arrowRight 键全局自定义这些图标。

圆点

使用 dots prop 显示一串圆点，用于滚动到特定幻灯片。

<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel v-slot="{ item }" dots :items="items" class="w-full max-w-xs mx-auto">
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>

圆点数量基于视图中显示的幻灯片数量

<script setup lang="ts">
const items = [
  'https://picsum.photos/640/640?random=1',
  'https://picsum.photos/640/640?random=2',
  'https://picsum.photos/640/640?random=3',
  'https://picsum.photos/640/640?random=4',
  'https://picsum.photos/640/640?random=5',
  'https://picsum.photos/640/640?random=6'
]
</script>

<template>
  <UCarousel v-slot="{ item }" dots :items="items" :ui="{ item: 'basis-1/3' }">
    <img :src="item" width="320" height="320" class="rounded-lg">
  </UCarousel>
</template>
