Textarea

一个用于输入多行文本的 textarea 元素。

用法

使用 v-model 指令控制 Textarea 的值。

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

<template>
  <UTextarea v-model="value" />
</template>

行数 (Rows)

使用 rows prop 设置行数。默认为 3

<template>
  <UTextarea :rows="12" />
</template>

占位符 (Placeholder)

使用 placeholder prop 设置占位符文本。

<template>
  <UTextarea placeholder="Type something..." />
</template>

自动调整大小 (Autoresize)

使用 autoresize prop 启用 Textarea 高度的自动调整。

<script setup lang="ts">
const value = ref('This is a long text that will autoresize the height of the Textarea.')
</script>

<template>
  <UTextarea v-model="value" autoresize />
</template>

使用 maxrows prop 设置自动调整大小时的最大行数。如果设置为 0,Textarea 将无限增长。

<script setup lang="ts">
const value = ref('This is a long text that will autoresize the height of the Textarea with a maximum of 4 rows.')
</script>

<template>
  <UTextarea v-model="value" :maxrows="4" autoresize />
</template>

颜色 (Color)

使用 color prop 更改 Textarea 获得焦点时的环形颜色。

<template>
  <UTextarea color="neutral" highlight placeholder="Type something..." />
</template>
此处使用 highlight prop 来显示焦点状态。在发生验证错误时,它在内部使用。

变体 (Variant)

使用 variant prop 更改 Textarea 的变体。

<template>
  <UTextarea color="neutral" variant="subtle" placeholder="Type something..." />
</template>

尺寸 (Size)

使用 size prop 更改 Textarea 的尺寸。

<template>
  <UTextarea size="xl" placeholder="Type something..." />
</template>

图标 (Icon) New

使用 icon prop 在 Textarea 内部显示一个 Icon

<template>
  <UTextarea icon="i-lucide-search" size="md" variant="outline" placeholder="Search..." :rows="1" />
</template>

使用 leadingtrailing prop 设置图标位置,或者使用 leading-icontrailing-icon prop 为每个位置设置不同的图标。

<template>
  <UTextarea trailing-icon="i-lucide-at-sign" placeholder="Enter your email" size="md" :rows="1" />
</template>

头像 (Avatar) New

使用 avatar prop 在 Textarea 内部显示一个 Avatar

<template>
  <UTextarea
    :avatar="{
      src: 'https://github.com/nuxt.png'
    }"
    size="md"
    variant="outline"
    placeholder="Search..."
    :rows="1"
  />
</template>

加载中 (Loading) New

使用 loading prop 在 Textarea 上显示一个加载图标。

<template>
  <UTextarea loading placeholder="Search..." :rows="1" />
</template>

加载图标 (Loading Icon) New

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

<template>
  <UTextarea loading loading-icon="i-lucide-loader" placeholder="Search..." :rows="1" />
</template>
你可以在 app.config.ts 中的 ui.icons.loading 键下全局自定义此图标。
你可以在 vite.config.ts 中的 ui.icons.loading 键下全局自定义此图标。

禁用 (Disabled)

使用 disabled prop 禁用 Textarea。

</template>
