Form表单

具有数据收集、校验和提交功能的表单,包含复选框、单选框、输入框、下拉选择框等元素。

表单#

我们为 form 提供了以下三种排列方式:

  • 水平排列:标签和表单控件水平排列;(默认)

  • 垂直排列:标签和表单控件上下垂直排列;

  • 行内排列:表单项水平行内排列。

表单域#

表单一定会包含表单域,表单域可以是输入控件,标准表单域,标签,下拉菜单,文本域等。

这里我们封装了表单域 <Form.Item />

<Form.Item {...props}>
  {children}
</Form.Item>

代码演示

水平登录栏,常用在顶部导航栏中。

自定义或第三方的表单控件,也可以与 Form 组件一起使用。只要该组件遵循以下的约定:

  • 提供受控属性 value 或其它与 valuePropName 的值同名的属性。

  • 提供 onChange 事件或 trigger 的值同名的事件。

  • 不能是函数式组件。

通过使用 onFieldsChangemapPropsToFields,可以把表单的数据存储到上层组件或者 Reduxdva 中,更多可参考 rc-form 示例

注意:mapPropsToFields 里面返回的表单域数据必须使用 Form.createFormField 包装。

expand codeexpand code
import { Form, Input } from 'antd';
const FormItem = Form.Item;

const CustomizedForm = Form.create({
  onFieldsChange(props, changedFields) {
    props.onChange(changedFields);

    return {
      username: Form.createFormField({
        ...props.username,
        value: props.username.value,
      }),
    };
  },
  onValuesChange(_, values) {
    console.log(values);
  },
})((props) => {
  const { getFieldDecorator } = props.form;
  return (
    <Form layout="inline">
      <FormItem label="Username">
        {getFieldDecorator('username', {
          rules: [{ required: true, message: 'Username is required!' }],
        })(<Input />)}
      </FormItem>
    </Form>
  );
});

class Demo extends React.Component {
  state = {
    fields: {
      username: {
        value: 'benjycui',
      },
    },
  };
  handleFormChange = (changedFields) => {
    this.setState(({ fields }) => ({
      fields: { ...fields, ...changedFields },
    }));
  }
  render() {
    const fields = this.state.fields;
    return (
      <div>
        <CustomizedForm {...fields} onChange={this.handleFormChange} />
        <pre className="language-bash">
          {JSON.stringify(fields, null, 2)}

      </div>
    );
  }

ReactDOM.render(<Demo />, mountNode);
A prime is a natural number greater than 1 that has no positive divisors other than 1 and itself.

使用 Form.create 处理后的表单具有自动收集数据并校验的功能,但如果您不需要这个功能,或者默认的行为无法满足业务需求,可以选择不使用 Form.create 并自行处理数据。

    };
  }
  return {
    validateStatus: 'error',
    errorMsg: 'The prime between 8 and 12 is 11!',
  };
}

  state = {
    number: {
      value: 11,

我们提供了 validateStatus help hasFeedback 等属性,你可以不需要使用 Form.creategetFieldDecorator,自己定义校验的时机和内容。

  1. validateStatus: 校验状态,可选 'success', 'warning', 'error', 'validating'。

  2. hasFeedback:用于给输入框添加反馈图标。

  3. help:设置校验文案。

API#

Form#

更多示例参考 rc-form

参数说明类型默认值
formForm.create() 包装过的组件会自带 this.props.form 属性,直接传给 Form 即可。1.7.0 之后无需设置object
hideRequiredMark隐藏所有表单项的必选标记Booleanfalse
layout表单布局(2.8 之后支持)'horizontal'|'vertical'|'inline''horizontal'
onSubmit数据验证成功后回调事件Function(e:Event)

Form.create(options)#

使用方式如下:

class CustomizedForm extends React.Component {}

CustomizedForm = Form.create({})(CustomizedForm);

options 的配置项如下。

参数说明类型
mapPropsToFields把父组件的属性映射到表单项上(如:把 Redux store 中的值读出),需要对返回值中的表单域数据用 Form.createFormField 标记(props) => Object{ fieldName: FormField { value } }
validateMessages默认校验信息,可用于把默认错误信息改为中文等,格式与 newMessages 返回值一致Object { nested.path: String }
onFieldsChangeForm.Item 子节点的值发生改变时触发,可以把对应的值转存到 Redux storeFunction(props, fields)
onValuesChange任一表单域的值发生改变时的回调(props, values) => void

经过 Form.create 包装的组件将会自带 this.props.form 属性,this.props.form 提供的 API 如下:

注意:使用 getFieldsValue getFieldValue setFieldsValue 等时,应确保对应的 field 已经用 getFieldDecorator 注册过了。

方法     说明                                    类型      
getFieldDecorator用于和表单进行双向绑定,详见下方描述
getFieldError获取某个输入控件的 ErrorFunction(name)
getFieldsError获取一组输入控件的 Error ,如不传入参数,则获取全部组件的 ErrorFunction([names: string[]])
getFieldsValue获取一组输入控件的值,如不传入参数,则获取全部组件的值Function([fieldNames: string[]])
getFieldValue获取一个输入控件的值Function(fieldName: string)
isFieldsTouched判断是否任一输入控件经历过 getFieldDecorator 的值收集时机 options.trigger(names?: string[]) => boolean
isFieldTouched判断一个输入控件是否经历过 getFieldDecorator 的值收集时机 options.trigger(name: string) => boolean
isFieldValidating判断一个输入控件是否在校验状态Function(name)
resetFields重置一组输入控件的值(为 initialValue)与状态,如不传入参数,则重置所有组件Function([names: string[]])
setFields设置一组输入控件的值与 Error。 代码Function({ fieldName: { value: any, errors: Error } })
setFieldsValue设置一组输入控件的值(注意:不要在 componentWillReceiveProps 内使用,否则会导致死循环,更多Function({ fieldName: value }
validateFields校验并获取一组输入域的值与 Error,若 fieldNames 参数为空,则校验全部组件Function([fieldNames: string[]], options: object, callback: Function(errors, values))
validateFieldsAndScrollvalidateFields 相似,但校验完后,如果校验不通过的菜单域不在可见范围内,则自动滚动进可见范围参考 validateFields

this.props.form.validateFields/validateFieldsAndScroll([fieldNames: string[]], options: object, callback: Function(errors, values))#

参数说明类型默认值
options.first若为 true,则每一表单域的都会在碰到第一个失败了的校验规则后停止校验booleanfalse
options.firstFields指定表单域会在碰到第一个失败了的校验规则后停止校验String[][]
options.force对已经校验过的表单域,在 validateTrigger 再次被触发时是否再次校验booleanfalse
options.scroll定义 validateFieldsAndScroll 的滚动行为,详细配置见 dom-scroll-into-view configObject{}

Form.createFormField#

用于标记 mapPropsToFields 返回的表单域数据,例子

this.props.form.getFieldDecorator(id, options)#

经过 getFieldDecorator 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. 不再需要也不应该onChange 来做同步,但还是可以继续监听 onChange 等事件。

  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 getFieldDecorator 里的 initialValue

  3. 你不应该用 setState,可以使用 this.props.form.setFieldsValue 来动态改变表单值。

特别注意#

  1. getFieldDecorator 不能用于装饰纯函数组件。

  2. 如果使用的是 react@<15.3.0,则 getFieldDecorator 调用不能位于纯函数组件中: https://github.com/facebook/react/pull/6534

getFieldDecorator(id, options) 参数#

参数说明类型默认值
id必填输入控件唯一标志。支持嵌套式的写法string
options.getValueFromEvent可以把 onChange 的参数(如 event)转化为控件的值function(..args)reference
options.initialValue子节点的初始值,类型、可选值均由子节点决定(注意:由于内部校验时使用 === 判断是否变化,建议使用变量缓存所需设置的值而非直接使用字面量))
options.normalize转换默认的 value 给控件,一个选择全部的例子function(value, prevValue, allValues): any-
options.rules校验规则,参考下方文档object[]
options.trigger收集子节点的值的时机string'onChange'
options.validateFirst当某一规则校验不通过时,是否停止剩下的规则的校验booleanfalse
options.validateTrigger校验子节点值的时机string|string[]'onChange'
options.valuePropName子节点的值的属性,如 Switch 的是 'checked'string'value'

更多参数请查看 rc-form option

Form.Item#

注意:

  • 一个 Form.Item 建议只放一个被 getFieldDecorator 装饰过的 child,当有多个被装饰过的 child 时,help required validateStatus 无法自动生成。

  • 2.2.0 之前,只有当表单域为 Form.Item 的子元素时,才会自动生成 help required validateStatus,嵌套情况需要自行设置。

参数说明类型默认值
colon配合 label 属性使用,表示是否显示 label 后面的冒号booleantrue
extra额外的提示信息,和 help 类似,当需要错误信息和提示文案同时出现时,可以使用这个。string|ReactNode
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booleanfalse
help提示信息,如不设置,则会根据校验规则自动生成string|ReactNode
labellabel 标签的文本string|ReactNode
labelCollabel 标签布局,同 <Col> 组件,设置 span offset 值,如 {span: 3, offset: 12}sm: {span: 3, offset: 12}object
required是否必填,如不设置,则会根据校验规则自动生成booleanfalse
validateStatus校验状态,如不设置,则会根据校验规则自动生成,可选:'success' 'warning' 'error' 'validating'string
wrapperCol需要为输入控件设置布局样式时,使用该属性,用法同 labelColobject

校验规则#

参数说明类型默认值
enum枚举类型string-
len字段长度number-
max最大长度number-
message校验文案string-
min最小长度number-
pattern正则表达式校验RegExp-
required是否必选booleanfalse
transform校验前转换字段值function(value) => transformedValue:any-
type内建校验类型,可选项string'string'
validator自定义校验(注意,callback 必须被调用function(rule, value, callback)-
whitespace必选时,空格是否会被视为错误booleanfalse

更多高级用法可研究 async-validator

在 TypeScript 中使用#

import { Form } from 'antd';
import { FormComponentProps } from 'antd/lib/form';

interface UserFormProps extends FormComponentProps {
  age: number;
  name: string;
}

class UserForm extends React.Component<UserFormProps, any> {

}
