"api": "/api/mock2/form/saveForm",
|

"body": [

"type": "input-number",
|
|
|
|
"name": "number",

## 原生数字组件
|
|
|
|
|
|
|
|
原生数字组件将直接使用浏览器的实现,最终展现效果和浏览器有关,而且只支持 `min`、`max`、`step` 这几个属性设置。
|
|
|
|
|
|
|
|
```schema: scope="body"
|
|
|
|
{
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
"api": "/api/mock2/form/saveForm",
|
2021-06-03 22:09:30 +08:00
|
|
|
"body": [
|

|
|
|
{
|
|
|
|
"type": "native-number",
|
