上一页下一页

用于显示一个按钮，或看起来像按钮的组件。

<script setup lang="ts">
import { ArrowUpIcon } from 'lucide-vue-next'
import { Button } from '@/components/ui/button'
</script>

<template>
  <div class="flex flex-wrap items-center gap-2 md:flex-row">
    <Button variant="outline">
      Button
    </Button>
    <Button variant="outline" size="icon" aria-label="Submit">
      <ArrowUpIcon />
    </Button>
  </div>
</template>

安装

pnpm dlx shadcn-vue@latest add button

使用方法

<script setup lang="ts">
import { Button } from '@/components/ui/button'
</script>

<template>
  <Button variant="outline">
    Button
  </Button>

光标 (Cursor)

Tailwind v4 已将按钮组件的 cursor: pointer 更改为 cursor: default。

如果你想保留 cursor: pointer 行为，请将以下代码添加到你的 CSS 文件中：

tailwind.css
@layer base {
  button:not(:disabled),
  [role="button"]:not(:disabled) {
    cursor: pointer;
  }
}

    </ButtonGroup>
  </ButtonGroup>
</template>

要创建按钮组，请使用 ButtonGroup 组件。详情请参阅 按钮组 (Button Group) 文档。

链接 (asChild)

你可以使用 as-child 属性使其他组件看起来像按钮。下面是一个看起来像按钮的链接示例。

<script setup lang="ts">
import { Button } from '@/components/ui/button'
</script>

<template>
  <Button as-child>
    <a href="/login">Login</a>
  </Button>
</template>
