# ButtonGroup 按钮组组件
|
||||
|
||||
`ButtonGroup` 是一个用于聚合多个 `MaterialButton` 的容器组件。它支持灵活的布局切换、统一的属性默认值配置以及全局事件委托监听。
|
||||
|
||||
## 核心特性
|
||||
|
||||
- **布局自适应**:支持水平(Horizontal)和垂直(Vertical)两种排列方式。
|
||||
- **属性继承与覆盖**:可以在组级别设置默认的尺寸、颜色、图标等,也可以在具体的按钮项中进行个性化覆盖。
|
||||
- **智能类型识别**:内置了对 `download` 和 `normal` 类型的样式及图标自动匹配逻辑。
|
||||
- **事件委托**:支持统一监听 `@click` 事件,便捷获取点击的项信息及索引。
|
||||
|
||||
## 组件属性 (Props)
|
||||
|
||||
| 属性名 | 类型 | 默认值 | 可选值 | 说明 |
|
||||
| :--- | :--- | :--- | :--- | :--- |
|
||||
| `links` | `ExternalLink[]` | `[]` | - | 按钮配置数组 |
|
||||
| `layout` | `string` | `"horizontal"` | `"horizontal"`, `"vertical"` | 布局方向 |
|
||||
| `size` | `string` | `"s"` | `"xs"`, `"s"`, `"m"`, `"l"`, `"xl"` | 默认按钮尺寸 |
|
||||
| `color` | `string` | - | - | 默认按钮颜色样式 |
|
||||
| `icon` | `string` | - | - | 默认按钮图标 |
|
||||
| `target` | `string` | - | - | 默认链接打开方式 |
|
||||
| `ariaLabel` | `string` | - | - | 组的无障碍标签 |
|
||||
|
||||
## 组件事件 (Emits)
|
||||
|
||||
| 事件名 | 回调参数 | 说明 |
|
||||
| :--- | :--- | :--- |
|
||||
| `@click` | `(event: Event, item: ExternalLink, index: number)` | 当组内任意按钮被点击时触发 |
|
||||
|
||||
## 按钮配置项 (ExternalLink)
|
||||
|
||||
每一项 `links` 中的对象支持以下配置:
|
||||
|
||||
| 属性名 | 类型 | 说明 |
|
||||
| :--- | :--- | :--- |
|
||||
| `label` | `string` | 按钮显示的文本内容 |
|
||||
| `id` | `string` | (可选) 自定义标识符,方便在事件处理中识别 |
|
||||
| `link` | `string` | (可选) 点击跳转的链接地址 |
|
||||

|
||||

|
||||
| `onClick` | `Function` | (可选) 单体独立的点击回调函数 |
|
||||
|
||||
## 使用示例
|
||||
|
||||
### 1. 基础用法 (水平排列)
|
||||
|
||||
```vue
|
||||
<ButtonGroup
|
||||
:links="[
|
||||
{ label: '查看详情', id: 'detail' },
|
||||
{ label: '下载资源', id: 'download', type: 'download' }
|
||||
]"
|
||||
@click="(e, item) => console.log('点击了:', item.id)"
|
||||
/>
|
||||
```
|
||||
|
||||
<ButtonGroup
|
||||
:links="[
|
||||
{ label: '查看详情', id: 'detail' },
|
||||
{ label: '下载资源', id: 'download', type: 'download' }
|
||||
]"
|
||||
@click="(e, item) => console.log('点击了:', item.id)"
|
||||
/>
|
||||
|
||||
### 2. 垂直排列与尺寸控制
|
||||
|
||||
```vue
|
||||
<ButtonGroup
|
||||
layout="vertical"
|
||||
size="l"
|
||||
:links="[
|
||||
{ label: '选项一', icon: 'settings' },
|
||||
{ label: '选项二', icon: 'person' }
|
||||
]"
|
||||
/>
|
||||
```
|
||||
|
||||
<ButtonGroup
|
||||
layout="vertical"
|
||||
size="l"
|
||||
:links="[
|
||||
{ label: '选项一', icon: 'settings' },
|
||||
{ label: '选项二', icon: 'person' }
|
||||
]"
|
||||
/>
|
||||
|
||||
### 3. 混合图标与文本
|
||||
|
||||
```vue
|
||||
<ButtonGroup
|
||||
size="m"
|
||||
:links="[
|
||||
{ id: 'prev', icon: 'chevron_left', ariaLabel: '上一页' },
|
||||
{ id: 'index', label: '1 / 5', color: 'tonal' },
|
||||
{ id: 'next', icon: 'chevron_right', ariaLabel: '下一页' }
|
||||
]"
|
||||
/>
|
||||
```
|
||||
|
||||
<ButtonGroup
|
||||
size="m"
|
||||
:links="[
|
||||
{ id: 'prev', icon: 'chevron_left', ariaLabel: '上一页' },
|
||||
{ id: 'index', label: '1 / 5', color: 'tonal' },
|
||||
{ id: 'next', icon: 'chevron_right', ariaLabel: '下一页' }
|
||||
]"
|
||||
/>
|
||||
|
||||
### 4. 链接跳转
|
||||
|
||||
```vue
|
||||
<ButtonGroup
|
||||
target="_blank"
|
||||
:links="[
|
||||
{ label: 'GitHub', link: 'https://github.com', icon: 'code' },
|
||||
{ label: '首页', link: '/', icon: 'home' }
|
||||
]"
|
||||
/>
|
||||
```
|
||||
|
||||
<ButtonGroup
|
||||
target="_blank"
|
||||
:links="[
|
||||
{ label: 'GitHub', link: 'https://github.com', icon: 'code' },
|
||||
{ label: '首页', link: '/', icon: 'home' }
|
||||
]"
|
||||
/>
