同样，你可以通过 actions 属性，配置任意你想要的行为按钮。

|

}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
请记住，如果想触发表单提交行为，请配置`"actionType": "submit"`或`"type": "submit"`按钮
|
|
|
|
|
|
|
|
|
|
|
|
### 去掉表单边框
|
|
|
|
|
|
|
|
|
|
|
|
通过配置`"wrapWithPanel": false`，可以去掉默认表单边框（包括标题，按钮栏以及边距样式等）。
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="250" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"wrapWithPanel": false,
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "email",
|
|
|
|
|
|
"label": "邮箱"
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "password",
|
|
|
|
|
|
"name": "password",
|
|
|
|
|
|
"label": "密码"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
**注意！配置该属性后，`title`和`actions`属性将失效并无法渲染，请在表单内自行配置。**
|
|
|
|
|
|
|
|
|
|
|
|
### 固定底部栏
|
|
|
|
|
|
|
|
|
|
|
|
如果表单项较多导致表单过长，而不方便操作底部的按钮栏，可以配置`"affixFooter": true`属性，将底部按钮栏固定在浏览器底部
|
|
|
|
|
|
|
|
|
|
|
|
## 表单项数据初始化
|
|
|
|
|
|
|
|
|
|
|
|
表单可以通过配置`initApi`，实现表单初始化时请求接口，用于展示数据或初始化表单项。
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="330" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"initApi": "https://houtai.baidu.com/api/mock2/form/initData",
|
|
|
|
|
|
"title": "编辑用户信息",
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "name",
|
|
|
|
|
|
"label": "姓名"
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "email",
|
|
|
|
|
|
"label": "邮箱"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```

### 轮询初始化请求
|
2020-07-28 10:03:53 +08:00
|
|
|
|
|
2020-12-02 17:02:44 +08:00
|
|
|
|
Form 支持轮询初始化接口，步骤如下：
|
2020-07-28 10:03:53 +08:00
|
|
|
|
|
|
|
|
|
|
1. 配置`initApi`
|
|
|
|
|
|
2. 配置 `interval`：单位为`ms`，最低值`3000`，低于该值按`3000`处理
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="300" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"initApi": "https://houtai.baidu.com/api/mock2/page/initData",
|
|
|
|
|
|
"interval": 3000,
|
|
|
|
|
|
"title": "表单",
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "date",
|
|
|
|
|
|
"label": "时间戳"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
2020-12-02 17:02:44 +08:00
|
|
|
|
如果希望在满足某个条件的情况下停止轮询，配置`stopAutoRefreshWhen`表达式。
|
2020-07-28 10:03:53 +08:00
|
|
|
|
|
|
|
|
|
|
```schema:height="300" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"initApi": "https://houtai.baidu.com/api/mock2/page/initData",
|
|
|
|
|
|
"interval": 3000,
|
|
|
|
|
|
"title": "表单",
|
2020-11-02 11:15:30 +08:00
|
|
|
|
"stopAutoRefreshWhen": "this.date % 5",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "date",
|
|
|
|
|
|
"label": "时间戳"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
2020-08-10 16:20:04 +08:00
|
|
|
|
### 静态初始化数据域
|
|
|
|
|
|
|
|
|
|
|
|
我们也可以手动设置 form 的数据域来初始化多个表单项值
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="330" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"data": {
|
|
|
|
|
|
"name": "rick",
|
|
|
|
|
|
"email": "rick@gmail.com"
|
|
|
|
|
|
},
|
|
|
|
|
|
"title": "用户信息",
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "name",
|
|
|
|
|
|
"label": "姓名"
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "email",
|
|
|
|
|
|
"name": "email",
|
|
|
|
|
|
"label": "邮箱"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
### 数据格式一致性问题
|
|
|
|
|
|
|
|
|
|
|
|
当表单来初始化表单项值时，需要保持数据格式的一致性。
|
|
|
|
|
|
|
|
|
|
|
|
如果表单初始化的值与表单项配置的数据格式不符合，而且用户没有再次操作该表单项，而直接提交表单，那么会将当前默认值原封不动的提交给后端，也许会导致不一致性的问题，我们看一个例子：
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="260" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"data": {
|
|
|
|
|
|
"select": ["a", "c"]
|
|
|
|
|
|
},
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"label": "选项",
|
|
|
|
|
|
"type": "select",
|
|
|
|
|
|
"name": "select",
|
|
|
|
|
|
"multiple": true,
|
|
|
|
|
|
"options": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"label":"A",
|
|
|
|
|
|
"value":"a"
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"label":"B",
|
|
|
|
|
|
"value":"b"
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"label":"C",
|
|
|
|
|
|
"value":"c"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
上例中， `select` 我们配置了`"multiple": true`，预期中，我们希望选中 `A` 和 `C` 项时，表单项的数据格式为：`"a,c"`，但是我们表单数据域中，`select`默认值为`"value": ["a", "c"]`，并不符合我们当前表单项的数据格式配置，这样会导致两个问题：
|
|
|
|
|
|
|
|
|
|
|
|
1. 有可能不会默认选中 `A` 和 `C` 选项；
|
|
|
|
|
|
2. 当不操作该表单项，直接提交时，预期是：`"a,c"`，但提交给后端的数据为：`["a", "c"]`，导致了不一致性的问题。
|
|
|
|
|
|
|
|
|
|
|
|
> 通过 `initApi` 配置默认值同理，不再赘述
|
|
|
|
|
|
|
|
|
|
|
|
因此一定确保默认值与选择器表单项数据格式配置相匹配。
|
|
|
|

|
|
|
|
## 表单提交
|
|
|
|
|
|
|
|
|
|
|
|
配置`api`属性，当表单执行提交行为时，会默认将当前表单数据域中的数据使用`post`方式发送给所配置`api`
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="330" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"initApi": "https://houtai.baidu.com/api/saveForm",
|
|
|
|
|
|
"title": "用户信息",
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "name",
|
|
|
|
|
|
"label": "姓名"
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "email",
|
|
|
|
|
|
"name": "email",
|
|
|
|
|
|
"label": "邮箱"
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
点击提交按钮，会看到发送表单请求，请求数据体为：
|
|
|
|
|
|
|
|
|
|
|
|
```json
|
|
|
|
|
|
{
|
|
|
|
|
|
"name": "xxx",
|
|
|
|
|
|
"email": "xxx@xx.com"
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
2020-09-10 17:16:11 +08:00
|
|
|
|
发送请求默认为 `POST` 方式，会将所有表单项整理成一个对象发送过过去。除此之外你可以主动获取以下信息。
|
|
|
|
|
|
|
|
|
|
|
|
- `diff` 只会包含 `diff` 结果
|
|
|
|
|
|
- `prinstine` 原始数据
|
|
|
|
|
|
如:
|
|
|
|
|
|
|
|
|
|
|
|
```json
|
|
|
|
|
|
{
|
|
|
|
|
|
"api": {
|
|
|
|
|
|
"method": "post",
|
|
|
|
|
|
"url": "/api/xxx/save",
|
|
|
|
|
|
"data": {
|
|
|
|
|
|
"modified": "$$",
|
|
|
|
|
|
"diff": "${diff}",
|
|
|
|
|
|
"origin": "${prinstine}"
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
> 如果 返回了 `data` 对象，且是对象，会把结果 merge 到表单数据里面。
|
|
|
|
|
|
|
|
|
|
|
|
当你需要配置特定的请求方式，请求体，`header`时，使用对象类型 api 配置，并使用 数据映射 进行数据配置。
|
|
|
|
|
|
|
|
|
|
|
|
下面示例我们更改了请求方法为`PUT`，并在原提交数据的基础上添加一个字段`"_from"`。更多用法查看 [API 文档](../../types/api) 和 [数据映射](../../concepts/data-mapping)文档

触发表单提交行为有下面几种方式：
|
|
|
|
|
|
|
|
|
|
|
|
1. 默认的`提交按钮`
|

通过设置`asyncApi`，当表单提交发送保存接口后，还会继续轮询请求该接口，默认间隔为`3秒`，直到返回 `finished` 属性为 `true` 才 结束。

## 重置表单
|
|
|

配置`"type": "reset"`或者`"actionType": "reset"`的按钮，可以实现点击重置表单项值。

## 表单数据域调试

配置`debug:true`可以查看当前表单的数据域数据详情，方便数据映射、表达式等功能调试，如下，你可以修改表单项查看数据域变化

|
|
|

}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
> 该配置不会展示完整的数据链，只会展示当前表单的数据域
|
|

|
|
|

|
## 禁用数据链
|
2019-09-26 18:49:32 +08:00
|
|
|
|
|
2020-07-28 10:03:53 +08:00
|
|
|
|
默认表单是可以获取到完整数据链中的数据的，但是该默认行为不适用于所有场景，例如：
|
2019-09-26 18:49:32 +08:00
|
|
|
|
|
2020-07-29 16:20:21 +08:00
|
|
|
|
在 CRUD 的列表项中配置弹框，弹框中有一个表单，则该表单项中所有的同`name`表单项都会根据上层`crud`的行数据进行初始化，如果你是实现编辑的功能那并没有是什么问题，但是如果你是新建功能，那么这将不符合你的预期，你可以手动设置`"canAccessSuperData": false`来关闭该行为
|
2019-09-26 18:49:32 +08:00
|
|
|
|
|
2020-07-28 10:03:53 +08:00

|
|
|
|
|
2020-07-28 10:03:53 +08:00
|
|
|
|
表单提交成功后，可以执行一些行为。

### 重置表单
|
|
|
|
|
|
|
|
|
|
|
|
如果想提交表单成功后，重置当前表单至初始状态，可以配置`"resetAfterSubmit": true`。
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="330" scope="body"
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "form",
|
|
|
|
|
|
"api": "https://houtai.baidu.com/api/mock2/form/saveForm",
|
|
|
|
|
|
"resetAfterSubmit": true,
|
|
|
|
|
|
"controls": [
|
|
|
|
|
|
{
|
|
|
|
|
|
"type": "text",
|
|
|
|
|
|
"name": "name",
|
|
|
|
|
|
"label": "姓名："
|
|
|
|
|
|
},
|
|
|
|
|
|
{
|
|
|
|
|
|
"name": "email",
|
|
|
|
|
|
"type": "email",
|
|
|
|
|
|
"label": "邮箱："
|
|
|
|
|
|
}
|
|
|
|
|
|
]
|
|
|
|
|
|
}
|
2020-06-04 16:33:48 +08:00
|
|
|
|
```
|
2020-07-28 10:03:53 +08:00
|
|
|
|
|
|
|
|
|
|
编辑表单项，点击提交，成功后会发现表单项的值会重置到初始状态，即空
|
|
|
|
|
|
|
|
|
|
|
|
> 注意，如果表单项有默认值，则会将该表单项的值重置至该默认值。
|
|
|
|
|
|
|
|
|
|
|
|
### 跳转页面
|
|
|
|
|
|
|
|
|
|
|
|
配置`redirect`属性，可以指定表单提交成功后要跳转至的页面
|
|
|
|
|
|
|
|
|
|
|
|
```schema:height="330" scope="body"

|
|
|

## 持久化保存表单项数据
|
|
|
|
|
|
|
|
|
|
|
|
表单默认在重置之后（切换页面、弹框中表单关闭表单），会自动清空掉表单中的所有数据，如果你想持久化保留当前表单项的数据而不清空它，那么配置`persistData:true`
|
|
|
|
|
|
|
|
|
|
|
|
如果想提交成功后，清空该缓存，则配置`"clearPersistDataAfterSubmit": true`
|
|
|
|
