Select

SelectGitHub
一个用于从选项列表中进行选择的下拉选择框。

用法

使用 v-model 指令控制 Select 的值，或者使用 default-value prop 设置初始值，当你不需要控制其状态时。

Items

使用 items prop 作为字符串、数字或布尔值的数组：

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" :items="items" class="w-48" />
</template>

你也可以传递一个对象数组，其中包含以下属性：

  • label?: string
  • value?: string
  • type?: "label" | "separator" | "item"
  • icon?: string
  • avatar?: AvatarProps
  • chip?: ChipProps
  • disabled?: boolean
  • class?: any
  • ui?: { label?: ClassNameValue, separator?: ClassNameValue, item?: ClassNameValue, itemLeadingIcon?: ClassNameValue, itemLeadingAvatarSize?: ClassNameValue, itemLeadingAvatar?: ClassNameValue, itemLeadingChipSize?: ClassNameValue, itemLeadingChip?: ClassNameValue, itemLabel?: ClassNameValue, itemTrailing?: ClassNameValue, itemTrailingIcon?: ClassNameValue }
<script setup lang="ts">
const items = ref([
  {
    label: 'Backlog',
    value: 'backlog'
  },
  {
    label: 'Todo',
    value: 'todo'
  },
  {
    label: 'In Progress',
    value: 'in_progress'
  },
  {
    label: 'Done',
    value: 'done'
  }
])
const value = ref('backlog')
</script>

<template>
  <USelect v-model="value" :items="items" class="w-48" />
</template>
当使用对象时，你需要引用 v-model 指令或 default-value prop 中对象的 value 属性。

你也可以向 items prop 传递一个数组的数组，以显示分隔的项目组。

<script setup lang="ts">
const items = ref([
  ['Apple', 'Banana', 'Blueberry', 'Grapes', 'Pineapple'],
  ['Aubergine', 'Broccoli', 'Carrot', 'Courgette', 'Leek']
])
const value = ref('Apple')
</script>

<template>
  <USelect v-model="value" :items="items" class="w-48" />
</template>

值键 (Value Key)

你可以使用 value-key prop 更改用于设置值的属性。默认为 value。

<script setup lang="ts">
const items = ref([
  {
    label: 'Backlog',
    id: 'backlog'
  },
  {
    label: 'Todo',
    id: 'todo'
  },
  {
    label: 'In Progress',
    id: 'in_progress'
  },
  {
    label: 'Done',
    id: 'done'
  }
])
const value = ref('backlog')
</script>

<template>
  <USelect v-model="value" value-key="id" :items="items" class="w-48" />
</template>

多选 (Multiple)

使用 multiple prop 允许多选，选定的项目将在触发器中用逗号分隔。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref(['Backlog', 'Todo'])
</script>

<template>
  <USelect v-model="value" multiple :items="items" class="w-48" />
</template>
确保将一个数组传递给 default-value prop 或 v-model 指令。

占位符 (Placeholder)

使用 placeholder prop 设置占位符文本。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
</script>

<template>
  <USelect placeholder="Select status" :items="items" class="w-48" />
</template>

内容 (Content)

使用 content prop 控制 Select 内容的渲染方式，例如其 align 或 side。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect
    v-model="value"
    :content="{
      align: 'center',
      side: 'bottom',
      sideOffset: 8
    }"
    :items="items"
    class="w-48"
  />
</template>

箭头 (Arrow)

使用 arrow prop 在 Select 上显示一个箭头。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" arrow :items="items" class="w-48" />
</template>

颜色 (Color)

使用 color prop 更改 Select 聚焦时的环形颜色。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" color="neutral" highlight :items="items" class="w-48" />
</template>
此处使用 highlight prop 来显示焦点状态。它在发生验证错误时内部使用。

变体 (Variant)

使用 variant prop 更改 Select 的变体。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" color="neutral" variant="subtle" :items="items" class="w-48" />
</template>

尺寸 (Size)

使用 size prop 更改 Select 的尺寸。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" size="xl" :items="items" class="w-48" />
</template>

图标 (Icon)

使用 icon prop 在 Select 内部显示一个 Icon。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" icon="i-lucide-search" size="md" :items="items" class="w-48" />
</template>

尾随图标 (Trailing Icon)

使用 trailing-icon prop 自定义尾随 Icon。默认为 i-lucide-chevron-down。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect
    v-model="value"
    trailing-icon="i-lucide-arrow-down"
    size="md"
    :items="items"
    class="w-48"
  />

    v-model="value"
    :avatar="{
      src: 'https://github.com/nuxt.png'
    }"
    :items="items"
    class="w-48"
  />
</template>

加载中 (Loading)

使用 loading prop 在 Select 上显示一个加载图标。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect v-model="value" loading :items="items" class="w-48" />
</template>

加载图标 (Loading Icon)

使用 loading-icon prop 自定义加载图标。默认为 i-lucide-loader-circle。

</script>

<template>
  <USelect disabled placeholder="Select status" :items="items" class="w-48" />
</template>

示例

带项目类型

你可以使用 type 属性，将其设置为 separator 以在项目之间显示分隔符，或设置为 label 以显示标签。

<script setup lang="ts">
const items = ref([
  {
    type: 'label',
    label: 'Fruits'
  },
  'Apple',
  'Banana',
  'Blueberry',
  'Grapes',
  'Pineapple',
  {
    type: 'separator'
  },
  {
    type: 'label',
    label: 'Vegetables'
  },
  'Aubergine',
  'Broccoli',
  'Carrot',
  'Courgette',
  'Leek'
])
const value = ref('Apple')
</script>

<template>
  <USelect v-model="value" :items="items" class="w-48" />
</template>

项目中带图标

你可以使用 icon 属性在项目内部显示一个 Icon。

<script setup lang="ts">
import type { SelectItem } from '@nuxt/ui'

const items = ref([
  {
    label: 'Backlog',
    value: 'backlog',
    icon: 'i-lucide-circle-help'
  },
  {
    label: 'Todo',
    value: 'todo',
    icon: 'i-lucide-circle-plus'

  },
  {
    label: 'Done',
    value: 'done',
    icon: 'i-lucide-circle-check'
  }
] satisfies SelectItem[])
const value = ref(items.value[0]?.value)

const icon = computed(() => items.value.find(item => item.value === value.value)?.icon)
</script>

<template>
  <USelect v-model="value" :items="items" value-key="value" :icon="icon" class="w-48" />
</template>
在此示例中，图标是根据所选项目的 value 属性计算得出的。
你也可以使用 #leading 插槽来显示选定的图标。

项目中带头像

你可以使用 avatar 属性在项目内部显示一个 Avatar。

<script setup lang="ts">
import type { SelectItem } from '@nuxt/ui'

const items = ref([
  {
    label: 'benjamincanac',
    value: 'benjamincanac',
    avatar: {
      src: 'https://github.com/benjamincanac.png',
      alt: 'benjamincanac'
    }
  },
  {
    label: 'romhml',
    value: 'romhml',
    avatar: {
      src: 'https://github.com/romhml.png',
      alt: 'romhml'
    }
  },
  {
    label: 'noook',
    value: 'noook',
    avatar: {
      src: 'https://github.com/noook.png',
      alt: 'noook'
    }
  },
  {
    label: 'sandros94',
    value: 'sandros94',
    avatar: {
      src: 'https://github.com/sandros94.png',
      alt: 'sandros94'
    }
  }
] satisfies SelectItem[])
const value = ref(items.value[0]?.value)

const avatar = computed(() => items.value.find(item => item.value === value.value)?.avatar)
</script>

<template>
  <USelect v-model="value" :items="items" value-key="value" :avatar="avatar" class="w-48" />
</template>
在此示例中，头像是根据所选项目的 value 属性计算得出的。
你也可以使用 #leading 插槽来显示选定的头像。

项目中带标记 (Chip)

你可以使用 chip 属性在项目内部显示一个 Chip。

<script setup lang="ts">
import type { SelectItem, ChipProps } from '@nuxt/ui'

const items = ref([
  {
    label: 'bug',
    value: 'bug',
    chip: {
      color: 'error'
    }
  },
  {
    label: 'feature',
    value: 'feature',
    chip: {
      color: 'success'
    }
  },
  {
    label: 'enhancement',
    value: 'enhancement',
    chip: {
      color: 'info'
    }
  }
] satisfies SelectItem[])

const value = ref(items.value[0]?.value)

function getChip(value: string) {
  return items.value.find(item => item.value === value)?.chip
}
</script>

<template>
  <USelect v-model="value" :items="items" value-key="value" class="w-48">
    <template #leading="{ modelValue, ui }">
      <UChip
        v-if="modelValue"
        v-bind="getChip(modelValue)"
        inset
        standalone
        :size="(ui.itemLeadingChipSize() as ChipProps['size'])"
        :class="ui.itemLeadingChip()"
      />
    </template>
  </USelect>
</template>
在此示例中，#leading 插槽用于显示选定的标记。

控制打开状态

你可以通过使用 default-open prop 或 v-model:open 指令来控制打开状态。

<script setup lang="ts">
const open = ref(false)
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')

defineShortcuts({
  o: () => open.value = !open.value
})
</script>

<template>
  <USelect v-model="value" v-model:open="open" :items="items" class="w-48" />
</template>
在此示例中，利用 defineShortcuts，你可以通过按下 O 来切换 Select。

带旋转图标

这是一个带旋转图标的示例，它指示 Select 的打开状态。

<script setup lang="ts">
const items = ref(['Backlog', 'Todo', 'In Progress', 'Done'])
const value = ref('Backlog')
</script>

<template>
  <USelect
    v-model="value"
    :items="items"
    :ui="{
      trailingIcon: 'group-data-[state=open]:rotate-180 transition-transform duration-200'
    }"
    class="w-48"
  />
</template>

带获取的项目

你可以从 API 获取项目并在 Select 中使用它们。

<script setup lang="ts">
import type { AvatarProps } from '@nuxt/ui'

const { data: users, status } = await useFetch('https://jsonplaceholder.typicode.com/users', {
  key: 'typicode-users',
  transform: (data: { id: number, name: string }[]) => {
    return data?.map(user => ({
      label: user.name,
      value: String(user.id),
      avatar: { src: `https://i.pravatar.cc/120?img=${user.id}` }
    }))
  },
  lazy: true
})

function getUserAvatar(value: string) {
  return users.value?.find(user => user.value === value)?.avatar || {}
}
</script>

<template>
  <USelect
    :items="users"
    :loading="status === 'pending'"
    icon="i-lucide-user"
    placeholder="Select user"
    class="w-48"
    value-key="value"
  >
    <template #leading="{ modelValue, ui }">
      <UAvatar
        v-if="modelValue"
        v-bind="getUserAvatar(modelValue)"
        :size="(ui.leadingAvatarSize() as AvatarProps['size'])"
        :class="ui.leadingAvatar()"
      />
    </template>
  </USelect>
</template>

适配内容宽度

你可以通过使用 ui.content 键将内容扩展到其项目的完整宽度。

<script setup lang="ts">
const value = ref<string>()

const { data: users } = await useFetch('https://jsonplaceholder.typicode.com/users', {
  key: 'typicode-users-email',
  transform: (data: { id: number, name: string, email: string }[]) => {
    return data?.map(user => ({
      label: user.name,
      email: user.email,
      value: String(user.id),
      avatar: { src: `https://i.pravatar.cc/120?img=${user.id}` }
    }))
  },
  lazy: true
})
</script>

<template>
  <USelect
    v-model="value"
    :items="users"
    placeholder="Select user"
    value-key="value"
    :ui="{ content: 'min-w-fit' }"
    class="w-48"
  >
    <template #item-label="{ item }">
      {{ item.label }}

      <span class="text-muted">
        {{ item.email }}
      </span>
    </template>
  </USelect>
</template>
你也可以在你的 app.config.ts 中全局更改内容宽度：
export default defineAppConfig({
  ui: {
    select: {
      slots: {
        content: 'min-w-fit'
      }
    }
  }
})

defaultValue

在你提供的 USelect（或者说是 SelectRoot）实现中，defaultValue 的使用逻辑是通过 useVModel 和 withDefaults 实现的，这与普通 Vue 组件稍有不同。它用于非受控模式，即你没有使用 v-model 来绑定 modelValue 时，defaultValue 会作为初始值生效。

正确使用 defaultValue

如果你没有传 v-model，你可以使用 defaultValue 设置初始选中项。

<USelect
  :options="options"
  defaultValue="1"
/>

组件内部代码关键部分：

const modelValue = useVModel(props, 'modelValue', emits, {
  defaultValue: props.defaultValue ?? (multiple.value ? [] : undefined),
  passive: (props.modelValue === undefined) as false,
  deep: true,
})

这个意思是：

  • 如果你没有传 modelValue（即不使用 v-model）；
  • 且你传了 defaultValue；
  • 那么组件内部就会将 modelValue.value = props.defaultValue。

注意事项

  1. defaultValue 只有在 首次渲染 时生效。之后组件内部的 modelValue 是响应式的，再传 defaultValue 不会改变值。
  2. 一旦你用了 v-model，组件就转为 “受控模式”，此时 defaultValue 将被忽略。
  3. 如果你用的是对象数组（例如 { label, value } 结构），你的 defaultValue 应该是 value 字段的值。

示例对比

方式一：用 v-model（受控）

<script setup>
const selected = ref('1')
</script>

<USelect v-model="selected" :options="[{ label: '启用', value: '1' }, { label: '禁用', value: '0' }]" />

方式二：用 defaultValue（非受控）

<USelect defaultValue="1" :options="[{ label: '启用', value: '1' }, { label: '禁用', value: '0' }]" />

如果你遇到 defaultValue 不生效 的情况，请确保：

  • 没有同时传 v-model；
  • 选项已经渲染（optionsSet 已更新）；
  • 默认值存在于选项 value 中。
