输入框自动完成功能。
## 何时使用
- 需要一个输入框而不是选择器。
- 需要输入建议/辅助提示。
和 Select 的区别是:
- AutoComplete 是一个带提示的文本输入框,用户可以自由输入,关键词是辅助**输入**。
- Select 是在限定的可选项中进行选择,关键词是**选择**。
## API
```html
<a-auto-complete v-model:value="value" :options="options" />
```
| 参数 | 说明 | 类型 | 默认值 | 版本 |
| --- | --- | --- | --- | --- |
| allowClear | 支持清除, 单选模式有效 | boolean | false | |
| autofocus | 自动获取焦点 | boolean | false | |
| backfill | 使用键盘选择选项的时候把选中项回填到输入框中 | boolean | false | |
| #default (自定义输入框) | 自定义输入框 | HTMLInputElement / HTMLTextAreaElement | `<Input />` | |
| options | 自动完成的数据源 | [DataSourceItemType](https://github.com/vueComponent/ant-design-vue/blob/724d53b907e577cf5880c1e6742d4c3f924f8f49/components/auto-complete/index.vue#L9)\[] | | |
