2015-10-29 08:42:34 +08:00
### validateMessages
2016-01-22 16:15:03 +08:00
Form 为验证提供了[默认的错误提示信息](https://github.com/ant-design/ant-design/blob/6234509d18bac1ac60fbb3f92a5b2c6a6361295a/components/locale/en_US.ts#L88-L134),你可以通过配置 `validateMessages` 属性,修改对应的提示模板。一种常见的使用方式,是配置国际化提示信息:
2016-01-22 16:15:03 +08:00
```jsx
const validateMessages = {
required: "'${name}' 是必选字段",
// ...
};
2016-01-22 16:15:03 +08:00
<Form validateMessages={validateMessages} />;
2016-01-22 16:15:03 +08:00
```
2022-12-13 15:49:05 +08:00
此外,[ConfigProvider](/components/config-provider-cn) 也提供了全局化配置方案,允许统一配置错误提示模板:
```jsx
const validateMessages = {
required: "'${name}' 是必选字段",
// ...
};
<ConfigProvider form={{ validateMessages }}>
<Form />
</ConfigProvider>;
```
2016-01-22 16:15:03 +08:00
## Form.Item
表单字段组件,用于数据双向绑定、校验、布局等。

| getValueFromEvent | 设置如何将 event 的值转换成字段值 | (..args: any\[]) => any | - | |
| getValueProps | 为子元素添加额外的属性 (不建议通过 `getValueProps` 生成动态函数 prop请直接将其传递给子组件) | (value: any) => Record<string, any> | - | 4.2.0 |
| hasFeedback | 配合 `validateStatus` 属性使用,展示校验状态图标,建议只配合 Input 组件使用 此外,它还可以通过 Icons 属性获取反馈图标。 | boolean \| { icons: [FeedbackIcons](#feedbackicons) } | false | icons: 5.9.0 |
| help | 提示信息,如不设置,则会根据校验规则自动生成 | ReactNode | - | |
| hidden | 是否隐藏字段(依然会收集和校验字段) | boolean | false | 4.4.0 |
| htmlFor | 设置子元素 label `htmlFor` 属性 | string | - | |

| label | `label` 标签的文本 | ReactNode | - | |
| labelAlign | 标签文本对齐方式 | `left` \| `right` | `right` | |
| labelCol | `label` 标签布局,同 `<Col>` 组件,设置 `span` `offset` 值,如 `{span: 3, offset: 12}``sm: {span: 3, offset: 12}`。你可以通过 Form 的 `labelCol` 进行统一设置,不会作用于嵌套 Item。当和 Form 同时设置时,以 Item 为准 | [object](/components/grid-cn#col) | - | |
| messageVariables | 默认验证字段的信息 | Record&lt;string, string> | - | 4.7.0 |

| preserve | 当字段被删除时保留字段值 | boolean | true | 4.4.0 |
| required | 必填样式设置。如不设置,则会根据校验规则自动生成 | boolean | false | |

| validateTrigger | 设置字段校验的时机 | string \| string\[] | `onChange` | |
| valuePropName | 子节点的值的属性。注意Switch、Checkbox 的 valuePropName 应该是是 `checked`,否则无法获取这个两个组件的值。该属性为 `getValueProps` 的封装,自定义 `getValueProps` 后会失效 | string | `value` | |
| wrapperCol | 需要为输入控件设置布局样式时,使用该属性,用法同 `labelCol`。你可以通过 Form 的 `wrapperCol` 进行统一设置,不会作用于嵌套 Item。当和 Form 同时设置时,以 Item 为准 | [object](/components/grid-cn#col) | - | |
被设置了 `name` 属性的 `Form.Item` 包装的控件,表单控件会自动添加 `value`(或 `valuePropName` 指定的其他属性) `onChange`(或 `trigger` 指定的其他属性),数据同步将被 Form 接管,这会导致以下结果:
1. 你**不再需要也不应该**用 `onChange` 来做数据收集同步(你可以使用 Form 的 `onValuesChange`),但还是可以继续监听 `onChange` 事件。
2. 你不能用控件的 `value``defaultValue` 等属性来设置表单域的值,默认值可以用 Form 里的 `initialValues` 来设置。注意 `initialValues` 不能被 `setState` 动态更新,你需要用 `setFieldsValue` 来更新。
3. 你不应该用 `setState`,可以使用 `form.setFieldsValue` 来动态改变表单值。
### dependencies
当字段间存在依赖关系时使用。如果一个字段设置了 `dependencies` 属性。那么它所依赖的字段更新时,该字段将自动触发更新与校验。一种常见的场景,就是注册用户表单的“密码”与“确认密码”字段。“确认密码”校验依赖于“密码”字段,设置 `dependencies` 后,“密码”字段更新会重新触发“校验密码”的校验逻辑。你可以参考[具体例子](#components-form-demo-dependencies)。
`dependencies` 不应和 `shouldUpdate` 一起使用,因为这可能带来更新逻辑的混乱。
### FeedbackIcons
`({ status: ValidateStatus, errors: ReactNode, warnings: ReactNode }) => Record<ValidateStatus, ReactNode>`
### shouldUpdate
Form 通过增量更新方式,只更新被修改的字段相关组件以达到性能优化目的。大部分场景下,你只需要编写代码或者与 [`dependencies`](#dependencies) 属性配合校验即可。而在某些特定场景,例如修改某个字段值后出现新的字段选项、或者纯粹希望表单任意变化都对某一个区域进行渲染。你可以通过 `shouldUpdate` 修改 Form.Item 的更新逻辑。
`shouldUpdate``true`Form 的任意变化都会使该 Form.Item 重新渲染。这对于自定义渲染一些区域十分有帮助,要注意 Form.Item 里包裹的子组件必须由函数返回,否则 `shouldUpdate` 不会起作用:
相关issue[#34500](https://github.com/ant-design/ant-design/issues/34500)
```jsx
<Form.Item shouldUpdate>
{() => {
return <pre>{JSON.stringify(form.getFieldsValue(), null, 2)}</pre>;
}}
</Form.Item>
```
你可以参考[示例](#components-form-demo-horizontal-login)查看具体使用场景。
`shouldUpdate` 为方法时,表单的每次数值更新都会调用该方法,提供原先的值与当前的值以供你比较是否需要更新。这对于是否根据值来渲染额外字段十分有帮助:
2017-11-17 21:19:10 +08:00
```jsx
<Form.Item shouldUpdate={(prevValues, curValues) => prevValues.additional !== curValues.additional}>
{() => {
return (
<Form.Item name="other">
<Input />
</Form.Item>
);
}}
</Form.Item>
```
2017-11-17 21:19:10 +08:00
你可以参考[示例](#components-form-demo-control-hooks)查看具体使用场景。
2016-01-30 19:00:56 +08:00
### messageVariables
你可以通过 `messageVariables` 修改 Form.Item 的默认验证信息。
```jsx
<Form>
<Form.Item
messageVariables={{ another: 'good' }}
label="user"
rules={[{ required: true, message: '${another} is required' }]}
>
<Input />
</Form.Item>
<Form.Item
messageVariables={{ label: 'good' }}
label={<span>user</span>}
rules={[{ required: true, message: '${label} is required' }]}
>
<Input />
</Form.Item>
</Form>
```
## Form.List

2023-07-27 09:56:05 +08:00
| name | 字段名支持数组。List 本身也是字段,因而 `getFieldsValue()` 默认会返回 List 下所有值,你可以通过[参数](#getfieldsvalue)改变这一行为 | [NamePath](#namepath) | - | |
| rules | 校验规则,仅支持自定义规则。需要配合 [ErrorList](#formerrorlist) 一同使用。 | { validator, message }\[] | - | 4.7.0 |
2016-05-10 18:41:10 +08:00
```tsx

))
}
</Form.List>
```
2016-05-11 11:32:43 +08:00

```
2018-09-12 22:16:53 +08:00
## Hooks
### Form.useForm
`type Form.useForm = (): [FormInstance]`
创建 Form 实例,用于管理所有数据状态。
### Form.useFormInstance
`type Form.useFormInstance = (): FormInstance`
`4.20.0` 新增,获取当前上下文正在使用的 Form 实例,常见于封装子组件消费无需透传 Form 实例:
```tsx
const Sub = () => {
const form = Form.useFormInstance();
return <Button onClick={() => form.setFieldsValue({})} />;
};
export default () => {
const [form] = Form.useForm();
return (
<Form form={form}>
<Sub />
</Form>
);
};
```
### Form.useWatch
`type Form.useWatch = (namePath: NamePath | (selector: (values: Store)) => any, formInstance?: FormInstance | WatchOptions): Value`
`5.12.0` 新增 `selector`
用于直接获取 form 中字段对应的值。通过该 Hooks 可以与诸如 `useSWR` 进行联动从而降低维护成本:
```tsx
const Demo = () => {
const [form] = Form.useForm();
const userName = Form.useWatch('username', form);
const { data: options } = useSWR(`/api/user/${userName}`, fetcher);
return (
<Form form={form}>
<Form.Item name="username">
<AutoComplete options={options} />
</Form.Item>
</Form>
);
};
```
如果你的组件被包裹在 `Form.Item` 内部,你可以省略第二个参数,`Form.useWatch` 会自动找到上层最近的 `FormInstance`
`useWatch` 默认只监听在 Form 中注册的字段,如果需要监听非注册字段,可以通过配置 `preserve` 进行监听:
```tsx
const Demo = () => {
const [form] = Form.useForm();
const age = Form.useWatch('age', { form, preserve: true });
console.log(age);
return (
<div>
<Button onClick={() => form.setFieldValue('age', 2)}>Update</Button>
<Form form={form}>
<Form.Item name="name">
<Input />
</Form.Item>
</Form>
</div>
);
};
```
### Form.Item.useStatus
`type Form.Item.useStatus = (): { status: ValidateStatus | undefined, errors: ReactNode[], warnings: ReactNode[] }`
`4.22.0` 新增,可用于获取当前 Form.Item 的校验状态,如果上层没有 Form.Item`status` 将会返回 `undefined`。`5.4.0` 新增 `errors``warnings`,可用于获取当前 Form.Item 的错误信息和警告信息:
```tsx
const CustomInput = ({ value, onChange }) => {
const { status, errors } = Form.Item.useStatus();
return (
<input
value={value}
onChange={onChange}
className={`custom-input-${status}`}
placeholder={(errors.length && errors[0]) || ''}
/>
);
};
export default () => (
<Form>
<Form.Item name="username">
<CustomInput />
</Form.Item>
</Form>
);
```
#### 与其他获取数据的方式的区别
Form 仅会对变更的 Field 进行刷新,从而避免完整的组件刷新可能引发的性能问题。因而你无法在 render 阶段通过 `form.getFieldsValue` 来实时获取字段值,而 `useWatch` 提供了一种特定字段访问的方式,从而使得在当前组件中可以直接消费字段的值。同时,如果为了更好的渲染性能,你可以通过 Field 的 renderProps 仅更新需要更新的部分。而当当前组件更新或者 effect 都不需要消费字段值时,则可以通过 `onValuesChange` 将数据抛出,从而避免组件更新。
### Interface
#### NamePath
`string | number | (string | number)[]`
2023-07-27 09:56:05 +08:00
#### GetFieldsValue
`getFieldsValue` 提供了多种重载方法:
##### getFieldsValue(nameList?: true | [NamePath](#namepath)\[], filterFunc?: FilterFunc)
当不提供 `nameList` 时,返回所有注册字段,这也包含 List 下所有的值(即便 List 下没有绑定 Item
`nameList``true` 时,返回 store 中所有的值,包含未注册字段。例如通过 `setFieldsValue` 设置了不存在的 Item 的值,也可以通过 `true` 全部获取。
`nameList` 为数组时,返回规定路径的值。需要注意的是,`nameList` 为嵌套数组。例如你需要某路径值应该如下:
```tsx
// 单个路径
form.getFieldsValue([['user', 'age']]);
// 多个路径
form.getFieldsValue([
['user', 'age'],
['preset', 'account'],
]);
```
##### getFieldsValue({ strict?: boolean, filter?: FilterFunc })
`5.8.0` 新增接受配置参数。当 `strict``true` 时会仅匹配 Item 的值。例如 `{ list: [{ bamboo: 1, little: 2 }] }` 中,如果 List 仅绑定了 `bamboo` 字段,那么 `getFieldsValue({ strict: true })` 会只获得 `{ list: [{ bamboo: 1 }] }`
#### FilterFunc
用于过滤一些字段值,`meta` 会返回字段相关信息。例如可以用来获取仅被用户修改过的值等等。
```tsx
type FilterFunc = (meta: { touched: boolean; validating: boolean }) => boolean;
```
#### FieldData
2021-04-12 17:48:28 +08:00
| 名称 | 说明 | 类型 |
| ---------- | ---------------- | ------------------------ |
| errors | 错误信息 | string\[] |
| warnings | 警告信息 | string\[] |
| name | 字段名称 | [NamePath](#namepath)\[] |
2021-04-12 17:48:28 +08:00
| touched | 是否被用户操作过 | boolean |
| validating | 是否正在校验 | boolean |
| value | 字段对应值 | any |
#### Rule
2020-05-13 12:11:58 +08:00
Rule 支持接收 object 进行配置,也支持 function 来动态获取 form 的数据:
```tsx
type Rule = RuleConfig | ((form: FormInstance) => RuleConfig);
```
| 名称 | 说明 | 类型 | 版本 |
| --- | --- | --- | --- |
| defaultField | 仅在 `type``array` 类型时有效,用于指定数组元素的校验规则 | [rule](#rule) | |
| enum | 是否匹配枚举中的值(需要将 `type` 设置为 `enum` | any\[] | |
| fields | 仅在 `type``array``object` 类型时有效,用于指定子元素的校验规则 | Record&lt;string, [rule](#rule)> | |
| len | string 类型时为字符串长度number 类型时为确定数字; array 类型时为数组长度 | number | |
| max | 必须设置 `type`string 类型为字符串最大长度number 类型时为最大值array 类型时为数组最大长度 | number | |
| message | 错误信息,不设置时会通过[模板](#validatemessages)自动生成 | string | |
| min | 必须设置 `type`string 类型为字符串最小长度number 类型时为最小值array 类型时为数组最小长度 | number | |
| pattern | 正则表达式匹配 | RegExp | |
| required | 是否为必选字段 | boolean | |
| transform | 将字段值转换成目标值后进行校验 | (value) => any | |
2024-04-17 15:54:42 +08:00
| type | 类型,常见有 `string` \|`number` \|`boolean` \|`url` \| `email`。更多请参考[此处](https://github.com/react-component/async-validator#type) | string | |
| validateTrigger | 设置触发验证时机,必须是 Form.Item 的 `validateTrigger` 的子集 | string \| string\[] | |
| validator | 自定义校验,接收 Promise 作为返回值。[示例](#components-form-demo-register)参考 | ([rule](#rule), value) => Promise | |
| warningOnly | 仅警告,不阻塞表单提交 | boolean | 4.17.0 |
| whitespace | 如果字段仅包含空格则校验不通过,只在 `type: 'string'` 时生效 | boolean | |
#### WatchOptions
| 名称 | 说明 | 类型 | 默认值 | 版本 |
| -------- | ------------------------------------- | ------------ | ---------------------- | ----- |
| form | 指定 Form 实例 | FormInstance | 当前 context 中的 Form | 5.4.0 |
| preserve | 是否监视没有对应的 `Form.Item` 的字段 | boolean | false | 5.4.0 |

## FAQ
### Switch、Checkbox 为什么不能绑定数据?
Form.Item 默认绑定值属性到 `value` 上,而 Switch、Checkbox 等组件的值属性为 `checked`。你可以通过 `valuePropName` 来修改绑定的值属性。
```tsx | pure
<Form.Item name="fieldA" valuePropName="checked">
<Switch />
</Form.Item>
```
2020-07-30 15:44:30 +08:00
### name 为数组时的转换规则?
2020-07-09 10:24:41 +08:00
`name` 为数组时,会按照顺序填充路径。当存在数字且 form store 中没有该字段时会自动转变成数组。因而如果需要数组为 key 时请使用 string 如:`['1', 'name']`。
### 为何在 Modal 中调用 form 控制台会报错?
> Warning: Instance created by `useForm` is not connect to any Form element. Forget to pass `form` prop?
这是因为你在调用 form 方法时Modal 还未初始化导致 form 没有关联任何 Form 组件。你可以通过给 Modal 设置 `forceRender` 将其预渲染。示例点击[此处](https://codesandbox.io/s/antd-reproduction-template-ibu5c)。
### 为什么 Form.Item 下的子组件 `defaultValue` 不生效?
当你为 Form.Item 设置 `name` 属性后,子组件会转为受控模式。因而 `defaultValue` 不会生效。你需要在 Form 上通过 `initialValues` 设置默认值。
### 为什么第一次调用 `ref` 的 Form 为空?
2020-08-25 11:27:01 +08:00
`ref` 仅在节点被加载时才会被赋值,请参考 React 官方文档:<https://reactjs.org/docs/refs-and-the-dom.html#accessing-refs>
2020-08-25 11:27:01 +08:00
### 为什么 `resetFields` 会重新 mount 组件?
`resetFields` 会重置整个 Field因而其子组件也会重新 mount 从而消除自定义组件可能存在的副作用(例如异步数据、状态等等)。
### Form 的 initialValues 与 Item 的 initialValue 区别?
在大部分场景下,我们总是推荐优先使用 Form 的 `initialValues`。只有存在动态字段时你才应该使用 Item 的 `initialValue`。默认值遵循以下规则:
1. Form 的 `initialValues` 拥有最高优先级
2020-04-12 14:44:29 +08:00
2. Field 的 `initialValue` 次之 \*. 多个同 `name` Item 都设置 `initialValue` 时,则 Item 的 `initialValue` 不生效
2023-07-06 17:51:38 +08:00
### 为什么 `getFieldsValue` 在初次渲染的时候拿不到值?
`getFieldsValue` 默认返回收集的字段数据,而在初次渲染时 Form.Item 节点尚未渲染,因而无法收集到数据。你可以通过 `getFieldsValue(true)` 来获取所有字段数据。
2023-09-22 13:41:36 +08:00
### 为什么 `setFieldsValue` 设置字段为 `undefined` 时,有的组件不会重置为空?
在 React 中,`value` 从确定值改为 `undefined` 表示从受控变为非受控,因而不会重置展示值(但是 Form 中的值确实已经改变)。你可以通过 HOC 改变这一逻辑:
```jsx
const MyInput = ({
// 强制保持受控逻辑
value = '',
...rest
}) => <input value={value} {...rest} />;
<Form.Item name="my">
<MyInput />
</Form.Item>;
```
### 为什么字段设置 `rules` 后更改值 `onFieldsChange` 会触发三次?
字段除了本身的值变化外,校验也是其状态之一。因而在触发字段变化会经历以下几个阶段:
1. Trigger value change
2. Rule validating
3. Rule validated
在触发过程中,调用 `isFieldValidating` 会经历 `false` > `true` > `false` 的变化过程。
### 为什么 Form.List 不支持 `label` 还需要使用 ErrorList 展示错误?
Form.List 本身是 renderProps内部样式非常自由。因而默认配置 `label``error` 节点很难与之配合。如果你需要 antd 样式的 `label`,可以通过外部包裹 Form.Item 来实现。
2020-09-23 22:24:09 +08:00
### 为什么 Form.Item 的 `dependencies` 对 Form.List 下的字段没有效果?
Form.List 下的字段需要包裹 Form.List 本身的 `name`,比如:
```tsx
<Form.List name="users">
{(fields) =>
fields.map((field) => (
2020-09-23 22:24:09 +08:00
<React.Fragment key={field.key}>
<Form.Item name={[field.name, 'name']} {...someRest1} />
<Form.Item name={[field.name, 'age']} {...someRest1} />
</React.Fragment>
))
}
</Form.List>
```
依赖则是:`['users', 0, 'name']`
### 为什么 `normalize` 不能是异步方法?
React 中异步更新会导致受控组件交互行为异常。当用户交互触发 `onChange` 后,通过异步改变值会导致组件 `value` 不会立刻更新,使得组件呈现假死状态。如果你需要异步触发变更,请通过自定义组件实现内部异步状态。

### `scrollToFirstError` 和 `scrollToField` 失效?
1. 使用了自定义表单控件
类似问题:[#28370](https://github.com/ant-design/ant-design/issues/28370) [#27994](https://github.com/ant-design/ant-design/issues/27994)
`5.17.0` 版本开始,滑动操作将优先使用表单控件元素所转发的 ref 元素。因此,在考虑自定义组件支持校验滚动时,请优先考虑将其转发给表单控件元素。
滚动依赖于表单控件元素上绑定的 `id` 字段,如果自定义控件没有将 `id` 赋到正确的元素上,这个功能将失效。你可以参考这个 [codesandbox](https://codesandbox.io/s/antd-reproduction-template-forked-25nul?file=/index.js)。

2. 页面内有多个表单
页面内如果有多个表单,且存在表单项 `name` 重复,表单滚动定位可能会查找到另一个表单的同名表单项上。需要给表单 `Form` 组件设置不同的 `name` 以区分。

### 继上,为何不通过 `ref` 绑定元素?
当自定义组件不支持 `ref`Form 无法获取子元素真实 DOM 节点,而通过包裹 Class Component 调用 `findDOMNode` 会在 React Strict Mode 下触发警告。因而我们使用 id 来进行元素定位。

### `setFieldsValue` 不会触发 `onFieldsChange` 和 `onValuesChange`
是的change 事件仅当用户交互才会触发。该设计是为了防止在 change 事件中调用 `setFieldsValue` 导致的循环问题。如果仅仅需要组件内消费,可以通过 `useWatch` 或者 `Field.renderProps` 来实现。

### 为什么 Form.Item 嵌套子组件后,不更新表单值?
Form.Item 在渲染时会注入 `value``onChange` 事件给子元素,当你的字段组件被包裹时属性将无法传递。所以以下代码是不会生效的:
```jsx
<Form.Item name="input">
<div>
<h3>I am a wrapped Input</h3>
<Input />
</div>
</Form.Item>
```
你可以通过 HOC 自定义组件形式来解决这个问题:
```jsx
const MyInput = (props) => (
<div>
<h3>I am a wrapped Input</h3>
<Input {...props} />
</div>
);
<Form.Item name="input">
<MyInput />
</Form.Item>;
```
