## 基本用法
2021-06-03 22:09:30 +08:00
按钮集合当 select 点选用。
2020-07-28 10:03:53 +08:00
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "form",
"api": "/api/mock2/form/saveForm",
2020-07-28 10:03:53 +08:00
"debug": true,
2021-06-03 22:09:30 +08:00
"body": [
2020-07-28 10:03:53 +08:00
{
2021-06-03 22:09:30 +08:00
"type": "button-group-select",
2020-07-28 10:03:53 +08:00
"label": "选项",
"name": "type",
"options": [
{
"label": "Option A",
"value": "a"
},
{
"label": "Option B",
"value": "b"
},
{
"label": "Option C",
"value": "c"
}
]
}
]
}
```
## 垂直模式
配置`"vertical": true`,实现垂直模式
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"body": [
{
"type": "button-group-select",
"label": "选项",
"name": "type",
"vertical": true,
"options": [
{
"label": "Option A",
"value": "a"
},
{
"label": "Option B",
"value": "b"
},
{
"label": "Option C",
"value": "c"
}
]
}
]
}
```
## 平铺模式
配置 `"tiled": true` 实现平铺模式
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"body": [
{
"type": "button-group-select",
"label": "选项",
"name": "type",
"tiled": true,
"options": [
{
"label": "Option A",
2020-07-28 10:03:53 +08:00
"value": "a"
},
{
"label": "Option B",
"value": "b"
},
{
"label": "Option C",
"value": "c"
}
]
}
]
}
```
## 按钮主题样式
配置 `btnLevel` 统一设置按钮主题样式,注意 `buttons ``options` 中的`level`属性优先级高于`btnLevel`。配置 `btnActiveLevel` 为按钮设置激活态时的主题样式。
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"debug": true,
"body": [
{
"type": "button-group-select",
"label": "选项",
"name": "type",
"btnLevel": "light",
"btnActiveLevel": "warning",
"options": [
{
"label": "Option A",
"value": "a"
},
{
"label": "Option B",
"value": "b"
},
{
"label": "Option C",
"value": "c",
"level": "primary"
2020-07-28 10:03:53 +08:00
}
]
}
]
}
```
## 属性表

## 事件表
2022-05-31 15:05:54 +08:00
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: string` 选中值 | 选中值变化时触发 |
## 动作表
2022-05-31 15:05:54 +08:00
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 |
| reload | - | 重新加载,调用 `source`,刷新数据域数据刷新(重新加载) |
| setValue | `value: string` 更新的值 | 更新数据 |
