## 基本用法
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
|
"api": "/api/mock2/form/saveForm",
|
2021-06-07 10:09:55 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"name": "switch",

|
|
|
|
"type": "switch",
|
|
|
|
|
"label": "开关",
|
|
|
|
|
"option": "开关说明"
|
|
|
|
|
}
|
|
|
|
|
]
|

## 配置真假值
|
|
|
|
|
|
|
|
|
|
默认情况:
|
2021-01-07 23:35:03 +08:00
|
|
|
|
|
2020-07-28 10:03:53 +08:00
|
|
|
|
- 开关打开时,表单项值为:true
|
|
|
|
|
- 开关关闭时,表单项值为:false
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"debug": true,
|
2021-06-07 10:09:55 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"name": "switch",
|
|
|
|
|
"type": "switch",
|
|
|
|
|
"label": "开关"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如果你想调整这个值,可以配置`trueValue`和`falseValue`
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"debug": true,
|
2021-06-07 10:09:55 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"name": "switch",
|
|
|
|
|
"type": "switch",
|
|
|
|
|
"label": "开关",
|
|
|
|
|
"trueValue": 1,
|
|
|
|
|
"falseValue": 0
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
调整开关,观察数据域变化,会发现打开后值为`1`,而关闭后为`0`
