@internationalized/number
包,该包提供了跨区域设置和编号系统格式化和解析数字的工具。用法
使用 v-model
指令控制 InputNumber 的值。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" />
</template>
当您不需要控制其状态时,使用 default-value
属性设置初始值。
<template>
<UInputNumber :default-value="5" />
</template>
最小值 / 最大值
使用 min
和 max
属性设置 InputNumber 的最小值和最大值。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" :min="0" :max="10" />
</template>
步长
使用 step
属性设置 InputNumber 的步长值。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" :step="2" />
</template>
方向
使用 orientation
属性更改 InputNumber 的方向。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" orientation="vertical" />
</template>
占位符
使用 placeholder
属性设置占位文本。
<template>
<UInputNumber placeholder="Enter a number" />
</template>
颜色
使用 color
属性更改 InputNumber 获得焦点时的外环颜色。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" color="neutral" highlight />
</template>
变体
使用 variant
属性更改 InputNumber 的变体。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" variant="subtle" color="neutral" />
</template>
尺寸
使用 size
属性更改 InputNumber 的尺寸。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" size="xl" />
</template>
禁用
使用 disabled
属性禁用 InputNumber。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value" disabled />
</template>
递增 / 递减
使用 increment
和 decrement
属性自定义递增和递减按钮,可以使用任何 Button 属性。默认为 { variant: 'link' }
。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber
v-model="value"
:increment="{
color: 'neutral',
variant: 'solid',
size: 'xs'
}"
:decrement="{
color: 'neutral',
variant: 'solid',
size: 'xs'
}"
/>
</template>
递增 / 递减 图标
使用 increment-icon
和 decrement-icon
属性自定义按钮的 Icon。默认为 i-lucide-plus
/ i-lucide-minus
。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber
v-model="value"
increment-icon="i-lucide-arrow-right"
decrement-icon="i-lucide-arrow-left"
/>
</template>
示例
使用小数格式
使用 format-options
属性自定义值的格式。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber
v-model="value"
:format-options="{
signDisplay: 'exceptZero',
minimumFractionDigits: 1
}"
/>
</template>
使用百分比格式
使用 format-options
属性和 style: 'percent'
来自定义值的格式。
<script setup lang="ts">
const value = ref(0.05)
</script>
<template>
<UInputNumber
v-model="value"
:step="0.01"
:format-options="{
style: 'percent'
}"
/>
</template>
使用货币格式
使用 format-options
属性和 style: 'currency'
来自定义值的格式。
<script setup lang="ts">
const value = ref(1500)
</script>
<template>
<UInputNumber
v-model="value"
:format-options="{
style: 'currency',
currency: 'EUR',
currencyDisplay: 'code',
currencySign: 'accounting'
}"
/>
</template>
在 FormField 中使用
您可以在 FormField 组件中使用 InputNumber,以显示标签、帮助文本、必填指示符等。
指定尝试次数
<script setup lang="ts">
const retries = ref(0)
</script>
<template>
<UFormField label="Retries" help="Specify number of attempts" required>
<UInputNumber v-model="retries" placeholder="Enter retries" />
</UFormField>
</template>
使用插槽
使用 #increment
和 #decrement
插槽自定义按钮。
<script setup lang="ts">
const value = ref(5)
</script>
<template>
<UInputNumber v-model="value">
<template #decrement>
<UButton size="xs" icon="i-lucide-minus" />
</template>
<template #increment>
<UButton size="xs" icon="i-lucide-plus" />
</template>
</UInputNumber>
</template>
