## 事件表
当前组件会对外派发以下事件,可以通过`onEvent`来监听这些事件,并通过`actions`来配置执行的动作,在`actions`中可以通过`event.data.xxx`事件参数变量来获取事件产生的数据,详细请查看[事件动作](../../docs/concepts/event-action)。
| 事件名称 | 事件参数 | 说明 |
| -------- | --------------------------------- | -------------- |
| change | `event.data.value: number` 评分值 | 分值变化时触发 |
## 动作表
当前组件对外暴露以下特性动作,其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作,动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数,详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。
| 动作名称 | 动作配置 | 说明 |
| -------- | ------------------------ | ------------------------------------------------------ |
| clear | - | 清空 |
| reset | - | 将值重置为`resetValue`,若没有配置`resetValue`,则清空 |
| setValue | `value: number` 更新的值 | 更新数据 |
