## 基本用法
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
|
|
"controls": [
|
|
{
|
|
"type": "month",
|
|
"name": "month",
|
|
"label": "时间"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 显示格式
|
|
|
|
选中月份，可以看到默认显示月份的格式是像`01`这样的格式，如果你想要自定义显示格式，那么可以配置`inputFormat`。
|
|
|
|
例如你想显示`01月`这样的格式，查找 moment 文档可知配置格式应为 `MM月`，即：
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
|
|
"controls": [
|
|
{
|
|
"type": "month",
|
|
"name": "month",
|
|
"label": "月份",
|
|
"inputFormat": "MM月"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
调整月份，观察显示格式
|
|
|
|
## 值格式
|
|
|
|
选中任意月份，可以看到默认表单项的值格式是像`1582992000`这样的时间戳格式。
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"debug": true,
|
|
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
|
|
"controls": [
|
|
{
|
|
"type": "month",
|
|
"name": "month",
|
|
"label": "月份"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
如果你想要其他格式的月份值，，那么可以配置`format`参数用于调整表单项的值格式。
|
|
|
|
例如你调整值为`01`这样的格式，查找 moment 文档可知配置格式应为 `MM`，即：
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"debug": true,
|
|
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
|
|
"controls": [
|
|
{
|
|
"type": "month",
|
|
"name": "month",
|
|
"label": "月份",
|
|
"format": "MM"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
调整月份，观察数据域中表单项值的变化
|
|
|
|
## 默认值
|
|
|
|
可以设置`value`属性，设置月份选择器的默认值
|
|
|
|
### 基本配置
|
|
|
|
配置符合当前 [值格式](./date#%E5%80%BC%E6%A0%BC%E5%BC%8F) 的默认值。
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"debug": true,
|
|
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
|
|
"controls": [
|
|
{
|
|
"type": "month",
|
|
"name": "month",
|
|
"label": "月份",
|
|
"value": "1582992000"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
### 相对值
|
|
|
|
`value` 还支持类似像`"+1hours"`这样的相对值，更加便捷的配置默认值
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"debug": true,
|
|
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
|
|
"controls": [
|
|
{
|
|
"type": "month",
|
|
"name": "month",
|
|
"label": "月份",
|
|
"value": "+1month"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
上例中配置了`"value": "+1month"`，默认就会选中一个月后。
|
|
|
|
支持的相对值关键字有：
|
|
|
|
- `now`: 当前时间
|
|
- `hour`或`hours`: 时
|
|
- `minute`或`minutes`: 分
|
|
- `second`或`seconds`: 秒
|
|
|
|
## 属性表
|
|
|
|
除了支持 [普通表单项属性表](./formitem#%E5%B1%9E%E6%80%A7%E8%A1%A8) 中的配置以外，还支持下面一些配置
|
|
|
|
