表单 Form - Ant Design

高性能表单控件，自带数据域管理。包含数据录入、校验以及对应样式。

何时使用

用于创建一个实体或收集信息。
需要对输入的数据类型进行校验时。

代码演示

基本的表单数据域控制展示，包含布局、初始化、验证、提交。

TypeScript
JavaScript
import React from 'react';
import { Button, Checkbox, Form, Input } from 'antd';

const onFinish = (values: any) => {
  console.log('Success:', values);
};

const onFinishFailed = (errorInfo: any) => {
  console.log('Failed:', errorInfo);
};

const App: React.FC = () => (
  <Form
    name="basic"
    labelCol={{ span: 8 }}
    wrapperCol={{ span: 16 }}
    style={{ maxWidth: 600 }}
    initialValues={{ remember: true }}
    onFinish={onFinish}
    onFinishFailed={onFinishFailed}
    autoComplete="off"
  >
    <Form.Item
      label="Username"
      name="username"
      rules={[{ required: true, message: 'Please input your username!' }]}
    >
      <Input />
    </Form.Item>

    <Form.Item
      label="Password"
      name="password"
      rules={[{ required: true, message: 'Please input your password!' }]}
    >
      <Input.Password />
    </Form.Item>

    <Form.Item name="remember" valuePropName="checked" wrapperCol={{ offset: 8, span: 16 }}>
      <Checkbox>Remember me</Checkbox>
    </Form.Item>

    <Form.Item wrapperCol={{ offset: 8, span: 16 }}>
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

表单方法调用

通过 Form.useForm 对表单数据域进行交互。

注意 useForm 是 React Hooks 的实现，只能用于函数组件，class 组件请查看下面的例子。

TypeScript
JavaScript
import { Button, Form, Input, Select } from 'antd';
import React from 'react';

const { Option } = Select;

const layout = {
  labelCol: { span: 8 },
  wrapperCol: { span: 16 },
};

const tailLayout = {
  wrapperCol: { offset: 8, span: 16 },
};

const App: React.FC = () => {
  const [form] = Form.useForm();

  const onGenderChange = (value: string) => {
    switch (value) {
      case 'male':
        form.setFieldsValue({ note: 'Hi, man!' });
        break;
      case 'female':
        form.setFieldsValue({ note: 'Hi, lady!' });
        break;
      case 'other':
        form.setFieldsValue({ note: 'Hi there!' });
        break;
      default:
    }
  };

  const onFinish = (values: any) => {
    console.log(values);
  };

  const onReset = () => {
    form.resetFields();
  };

  const onFill = () => {
    form.setFieldsValue({ note: 'Hello world!', gender: 'male' });
  };

  return (
    <Form
      {...layout}
      form={form}
      name="control-hooks"
      onFinish={onFinish}
      style={{ maxWidth: 600 }}
    >
      <Form.Item name="note" label="Note" rules={[{ required: true }]}>
        <Input />
      </Form.Item>
      <Form.Item name="gender" label="Gender" rules={[{ required: true }]}>
        <Select
          placeholder="Select a option and change input text above"
          onChange={onGenderChange}
          allowClear
        >
          <Option value="male">male</Option>
          <Option value="female">female</Option>
          <Option value="other">other</Option>
        </Select>
      </Form.Item>
      <Form.Item
        noStyle
        shouldUpdate={(prevValues, currentValues) => prevValues.gender !== currentValues.gender}
      >
        {({ getFieldValue }) =>
          getFieldValue('gender') === 'other' ? (
            <Form.Item name="customizeGender" label="Customize Gender" rules={[{ required: true }]}>
              <Input />
            </Form.Item>
          ) : null
        }
      </Form.Item>
      <Form.Item {...tailLayout}>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
        <Button htmlType="button" onClick={onReset}>
          Reset
        </Button>
        <Button type="link" htmlType="button" onClick={onFill}>
          Fill form
        </Button>
      </Form.Item>
    </Form>
  );
};

export default App;
#components-form-demo-control-hooks .ant-btn {
  margin-right: 8px;
}

表单方法调用（Class component）

我们推荐使用 Form.useForm 创建表单数据域进行控制。如果是在 class component 下，你也可以通过 ref 获取数据域。

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, Select } from 'antd';
import type { FormInstance } from 'antd/es/form';

const { Option } = Select;

const layout = {
  labelCol: { span: 8 },
  wrapperCol: { span: 16 },
};

const tailLayout = {
  wrapperCol: { offset: 8, span: 16 },
};

const App: React.FC = () => {
  const formRef = React.useRef<FormInstance>(null);

  const onGenderChange = (value: string) => {
    switch (value) {
      case 'male':
        formRef.current?.setFieldsValue({ note: 'Hi, man!' });
        break;
      case 'female':
        formRef.current?.setFieldsValue({ note: 'Hi, lady!' });
        break;
      case 'other':
        formRef.current?.setFieldsValue({ note: 'Hi there!' });
        break;
      default:
        break;
    }
  };

  const onFinish = (values: any) => {
    console.log(values);
  };

  const onReset = () => {
    formRef.current?.resetFields();
  };

  const onFill = () => {
    formRef.current?.setFieldsValue({ note: 'Hello world!', gender: 'male' });
  };

  return (
    <Form
      {...layout}
      ref={formRef}
      name="control-ref"
      onFinish={onFinish}
      style={{ maxWidth: 600 }}
    >
      <Form.Item name="note" label="Note" rules={[{ required: true }]}>
        <Input />
      </Form.Item>
      <Form.Item name="gender" label="Gender" rules={[{ required: true }]}>
        <Select
          placeholder="Select a option and change input text above"
          onChange={onGenderChange}
          allowClear
        >
          <Option value="male">male</Option>
          <Option value="female">female</Option>
          <Option value="other">other</Option>
        </Select>
      </Form.Item>
      <Form.Item
        noStyle
        shouldUpdate={(prevValues, currentValues) => prevValues.gender !== currentValues.gender}
      >
        {({ getFieldValue }) =>
          getFieldValue('gender') === 'other' ? (
            <Form.Item name="customizeGender" label="Customize Gender" rules={[{ required: true }]}>
              <Input />
            </Form.Item>
          ) : null
        }
      </Form.Item>
      <Form.Item {...tailLayout}>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
        <Button htmlType="button" onClick={onReset}>
          Reset
        </Button>
        <Button type="link" htmlType="button" onClick={onFill}>
          Fill form
        </Button>
      </Form.Item>
    </Form>
  );
};

export default App;
#components-form-demo-control-ref .ant-btn {
  margin-right: 8px;
}

表单有三种布局。

TypeScript
JavaScript
import { Button, Form, Input, Radio } from 'antd';
import React, { useState } from 'react';

type LayoutType = Parameters<typeof Form>[0]['layout'];

const App: React.FC = () => {
  const [form] = Form.useForm();
  const [formLayout, setFormLayout] = useState<LayoutType>('horizontal');

  const onFormLayoutChange = ({ layout }: { layout: LayoutType }) => {
    setFormLayout(layout);
  };

  const formItemLayout =
    formLayout === 'horizontal' ? { labelCol: { span: 4 }, wrapperCol: { span: 14 } } : null;

  const buttonItemLayout =
    formLayout === 'horizontal' ? { wrapperCol: { span: 14, offset: 4 } } : null;

  return (
    <Form
      {...formItemLayout}
      layout={formLayout}
      form={form}
      initialValues={{ layout: formLayout }}
      onValuesChange={onFormLayoutChange}
      style={{ maxWidth: formLayout === 'inline' ? 'none' : 600 }}
    >
      <Form.Item label="Form Layout" name="layout">
        <Radio.Group value={formLayout}>
          <Radio.Button value="horizontal">Horizontal</Radio.Button>
          <Radio.Button value="vertical">Vertical</Radio.Button>
          <Radio.Button value="inline">Inline</Radio.Button>
        </Radio.Group>
      </Form.Item>
      <Form.Item label="Field A">
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item label="Field B">
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item {...buttonItemLayout}>
        <Button type="primary">Submit</Button>
      </Form.Item>
    </Form>
  );
};

export default App;

Form disabled

设置表单组件禁用，仅对 antd 组件有效。

TypeScript
JavaScript
import { PlusOutlined } from '@ant-design/icons';
import {
  Button,
  Cascader,
  Checkbox,
  DatePicker,
  Form,
  Input,
  InputNumber,
  Radio,
  Select,
  Switch,
  TreeSelect,
  Upload,
} from 'antd';
import React, { useState } from 'react';

const { RangePicker } = DatePicker;
const { TextArea } = Input;

const normFile = (e: any) => {
  if (Array.isArray(e)) {
    return e;
  }
  return e?.fileList;
};

const FormDisabledDemo: React.FC = () => {
  const [componentDisabled, setComponentDisabled] = useState<boolean>(true);

  return (
    <>
      <Checkbox
        checked={componentDisabled}
        onChange={(e) => setComponentDisabled(e.target.checked)}
      >
        Form disabled
      </Checkbox>
      <Form
        labelCol={{ span: 4 }}
        wrapperCol={{ span: 14 }}
        layout="horizontal"
        disabled={componentDisabled}
        style={{ maxWidth: 600 }}
      >
        <Form.Item label="Checkbox" name="disabled" valuePropName="checked">
          <Checkbox>Checkbox</Checkbox>
        </Form.Item>
        <Form.Item label="Radio">
          <Radio.Group>
            <Radio value="apple"> Apple </Radio>
            <Radio value="pear"> Pear </Radio>
          </Radio.Group>
        </Form.Item>
        <Form.Item label="Input">
          <Input />
        </Form.Item>
        <Form.Item label="Select">
          <Select>
            <Select.Option value="demo">Demo</Select.Option>
          </Select>
        </Form.Item>
        <Form.Item label="TreeSelect">
          <TreeSelect
            treeData={[
              { title: 'Light', value: 'light', children: [{ title: 'Bamboo', value: 'bamboo' }] },
            ]}
          />
        </Form.Item>
        <Form.Item label="Cascader">
          <Cascader
            options={[
              {
                value: 'zhejiang',
                label: 'Zhejiang',
                children: [
                  {
                    value: 'hangzhou',
                    label: 'Hangzhou',
                  },
                ],
              },
            ]}
          />
        </Form.Item>
        <Form.Item label="DatePicker">
          <DatePicker />
        </Form.Item>
        <Form.Item label="RangePicker">

        </Form.Item>
        <Form.Item label="InputNumber">
          <InputNumber />
        </Form.Item>
        <Form.Item label="TextArea">
          <TextArea rows={4} />
        </Form.Item>
        <Form.Item label="Switch" valuePropName="checked">
          <Switch />
        </Form.Item>
        <Form.Item label="Upload" valuePropName="fileList" getValueFromEvent={normFile}>
          <Upload action="/upload.do" listType="picture-card">
            <div>
              <PlusOutlined />
              <div style={{ marginTop: 8 }}>Upload</div>
            </div>
          </Upload>
        </Form.Item>
        <Form.Item label="Button">
          <Button>Button</Button>
        </Form.Item>
      </Form>
    </>
  );
};

export default () => <FormDisabledDemo />;

通过 requiredMark 切换必选与可选样式。

TypeScript
JavaScript
import React, { useState } from 'react';
import { InfoCircleOutlined } from '@ant-design/icons';
import { Button, Form, Input, Radio } from 'antd';

type RequiredMark = boolean | 'optional';

const App: React.FC = () => {
  const [form] = Form.useForm();
  const [requiredMark, setRequiredMarkType] = useState<RequiredMark>('optional');

  const onRequiredTypeChange = ({ requiredMarkValue }: { requiredMarkValue: RequiredMark }) => {
    setRequiredMarkType(requiredMarkValue);
  };

  return (
    <Form
      form={form}
      layout="vertical"
      initialValues={{ requiredMarkValue: requiredMark }}
      onValuesChange={onRequiredTypeChange}
      requiredMark={requiredMark}
    >
      <Form.Item label="Required Mark" name="requiredMarkValue">
        <Radio.Group>
          <Radio.Button value="optional">Optional</Radio.Button>
          <Radio.Button value>Required</Radio.Button>
          <Radio.Button value={false}>Hidden</Radio.Button>
        </Radio.Group>
      </Form.Item>
      <Form.Item label="Field A" required tooltip="This is a required field">
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item
        label="Field B"
        tooltip={{ title: 'Tooltip with customize icon', icon: <InfoCircleOutlined /> }}
      >
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item>
        <Button type="primary">Submit</Button>
      </Form.Item>
    </Form>
  );
};

export default App;

设置表单组件尺寸，仅对 antd 组件有效。

TypeScript
JavaScript
import React, { useState } from 'react';
import {
  Button,
  Cascader,
  DatePicker,
  Form,
  Input,
  InputNumber,
  Radio,
  Select,
  Switch,
  TreeSelect,
} from 'antd';

type SizeType = Parameters<typeof Form>[0]['size'];

const App: React.FC = () => {
  const [componentSize, setComponentSize] = useState<SizeType | 'default'>('default');

  const onFormLayoutChange = ({ size }: { size: SizeType }) => {
    setComponentSize(size);
  };

  return (
    <Form
      labelCol={{ span: 4 }}
      wrapperCol={{ span: 14 }}
      layout="horizontal"
      initialValues={{ size: componentSize }}
      onValuesChange={onFormLayoutChange}
      size={componentSize as SizeType}
      style={{ maxWidth: 600 }}
    >
      <Form.Item label="Form Size" name="size">
        <Radio.Group>
          <Radio.Button value="small">Small</Radio.Button>
          <Radio.Button value="default">Default</Radio.Button>
          <Radio.Button value="large">Large</Radio.Button>
        </Radio.Group>
      </Form.Item>
      <Form.Item label="Input">
        <Input />
      </Form.Item>
      <Form.Item label="Select">
        <Select>
          <Select.Option value="demo">Demo</Select.Option>
        </Select>
      </Form.Item>
      <Form.Item label="TreeSelect">
        <TreeSelect
          treeData={[
            { title: 'Light', value: 'light', children: [{ title: 'Bamboo', value: 'bamboo' }] },
          ]}
        />
      </Form.Item>
      <Form.Item label="Cascader">
        <Cascader
          options={[
            {
              value: 'zhejiang',
              label: 'Zhejiang',
              children: [{ value: 'hangzhou', label: 'Hangzhou' }],
            },
          ]}
        />
      </Form.Item>
      <Form.Item label="DatePicker">
        <DatePicker />
      </Form.Item>
      <Form.Item label="InputNumber">
        <InputNumber />
      </Form.Item>
      <Form.Item label="Switch" valuePropName="checked">
        <Switch />
      </Form.Item>
      <Form.Item label="Button">
        <Button>Button</Button>
      </Form.Item>
    </Form>
  );
};

export default App;

表单标签可换行

使用 labelWrap 可以开启 label 换行。

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input } from 'antd';

const App: React.FC = () => (
  <Form
    name="wrap"
    labelCol={{ flex: '110px' }}
    labelAlign="left"
    labelWrap
    wrapperCol={{ flex: 1 }}
    colon={false}
    style={{ maxWidth: 600 }}
  >
    <Form.Item label="正常标签文案" name="username" rules={[{ required: true }]}>
      <Input />
    </Form.Item>

    <Form.Item label="超长标签文案超长标签文案" name="password" rules={[{ required: true }]}>
      <Input />
    </Form.Item>

    <Form.Item label=" ">
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

非阻塞校验

rule 添加 warningOnly 后校验不再阻塞表单提交。

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, message, Space } from 'antd';

const App: React.FC = () => {
  const [form] = Form.useForm();

  const onFinish = () => {
    message.success('Submit success!');
  };

  const onFinishFailed = () => {
    message.error('Submit failed!');
  };

  const onFill = () => {
    form.setFieldsValue({
      url: 'https://taobao.com/',
    });
  };

  return (
    <Form
      form={form}
      layout="vertical"
      onFinish={onFinish}
      onFinishFailed={onFinishFailed}
      autoComplete="off"
    >
      <Form.Item
        name="url"
        label="URL"
        rules={[{ required: true }, { type: 'url', warningOnly: true }, { type: 'string', min: 6 }]}
      >
        <Input placeholder="input placeholder" />
      </Form.Item>
      <Form.Item>
        <Space>
          <Button type="primary" htmlType="submit">
            Submit
          </Button>
          <Button htmlType="button" onClick={onFill}>
            Fill
          </Button>
        </Space>
      </Form.Item>
    </Form>
  );
};

export default App;

Name Value:

字段监听 Hooks

useWatch 允许你监听字段变化，同时仅当该字段变化时重新渲染。API 文档请查阅此处。

TypeScript
JavaScript
import React from 'react';
import { Form, Input, InputNumber, Typography } from 'antd';

const Demo: React.FC = () => {
  const [form] = Form.useForm<{ name: string; age: number }>();
  const nameValue = Form.useWatch('name', form);

  return (
    <>
      <Form form={form} layout="vertical" autoComplete="off">
        <Form.Item name="name" label="Name (Watch to trigger rerender)">
          <Input />
        </Form.Item>
        <Form.Item name="age" label="Age (Not Watch)">
          <InputNumber />
        </Form.Item>
      </Form>

      <Typography>
        <pre>Name Value: {nameValue}</pre>
      </Typography>
    </>
  );
};

export default Demo;

通过 validateFields 的 validateOnly 可以动态调整提交按钮的 disabled 状态。

TypeScript
JavaScript
import type { FormInstance } from 'antd';
import { Button, Form, Input, Space } from 'antd';
import React from 'react';

const SubmitButton = ({ form }: { form: FormInstance }) => {
  const [submittable, setSubmittable] = React.useState(false);

  // Watch all values
  const values = Form.useWatch([], form);

  React.useEffect(() => {
    form.validateFields({ validateOnly: true }).then(
      () => {
        setSubmittable(true);
      },
      () => {
        setSubmittable(false);
      },
    );
  }, [values]);

  return (
    <Button type="primary" htmlType="submit" disabled={!submittable}>
      Submit
    </Button>
  );
};

const App = () => {
  const [form] = Form.useForm();

  return (
    <Form form={form} name="validateOnly" layout="vertical" autoComplete="off">
      <Form.Item name="name" label="Name" rules={[{ required: true }]}>
        <Input />
      </Form.Item>
      <Form.Item name="age" label="Age" rules={[{ required: true }]}>
        <Input />
      </Form.Item>
      <Form.Item>
        <Space>
          <SubmitButton form={form} />
          <Button htmlType="reset">Reset</Button>
        </Space>
      </Form.Item>
    </Form>
  );
};

export default App;

字段路径前缀

在某些场景，你希望统一设置一些字段的前缀。你可以通过 HOC 实现该效果。

TypeScript
JavaScript
import React from 'react';
import { Form, Input, Button } from 'antd';
import type { FormItemProps } from 'antd';

const MyFormItemContext = React.createContext<(string | number)[]>([]);

interface MyFormItemGroupProps {
  prefix: string | number | (string | number)[];
  children: React.ReactNode;
}

function toArr(str: string | number | (string | number)[]): (string | number)[] {
  return Array.isArray(str) ? str : [str];
}

const MyFormItemGroup = ({ prefix, children }: MyFormItemGroupProps) => {
  const prefixPath = React.useContext(MyFormItemContext);
  const concatPath = React.useMemo(() => [...prefixPath, ...toArr(prefix)], [prefixPath, prefix]);

  return <MyFormItemContext.Provider value={concatPath}>{children}</MyFormItemContext.Provider>;
};

const MyFormItem = ({ name, ...props }: FormItemProps) => {
  const prefixPath = React.useContext(MyFormItemContext);
  const concatName = name !== undefined ? [...prefixPath, ...toArr(name)] : undefined;

  return <Form.Item name={concatName} {...props} />;
};

const App: React.FC = () => {
  const onFinish = (value: object) => {
    console.log(value);
  };

  return (
    <Form name="form_item_path" layout="vertical" onFinish={onFinish}>
      <MyFormItemGroup prefix={['user']}>
        <MyFormItemGroup prefix={['name']}>
          <MyFormItem name="firstName" label="First Name">
            <Input />
          </MyFormItem>
          <MyFormItem name="lastName" label="Last Name">
            <Input />
          </MyFormItem>
        </MyFormItemGroup>

        <MyFormItem name="age" label="Age">
          <Input />
        </MyFormItem>
      </MyFormItemGroup>

      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form>
  );
};

export default App;

动态增减表单项

动态增加、减少表单项。add 方法参数可用于设置初始值。

TypeScript
JavaScript
import React from 'react';
import { MinusCircleOutlined, PlusOutlined } from '@ant-design/icons';
import { Button, Form, Input } from 'antd';

const formItemLayout = {
  labelCol: {
    xs: { span: 24 },
    sm: { span: 4 },
  },
  wrapperCol: {
    xs: { span: 24 },
    sm: { span: 20 },
  },
};

const formItemLayoutWithOutLabel = {
  wrapperCol: {
    xs: { span: 24, offset: 0 },
    sm: { span: 20, offset: 4 },
  },
};

const App: React.FC = () => {
  const onFinish = (values: any) => {
    console.log('Received values of form:', values);
  };

  return (
    <Form
      name="dynamic_form_item"
      {...formItemLayoutWithOutLabel}
      onFinish={onFinish}
      style={{ maxWidth: 600 }}
    >
      <Form.List
        name="names"
        rules={[
          {
            validator: async (_, names) => {
              if (!names || names.length < 2) {
                return Promise.reject(new Error('At least 2 passengers'));
              }
            },
          },
        ]}
      >
        {(fields, { add, remove }, { errors }) => (
          <>
            {fields.map((field, index) => (
              <Form.Item
                {...(index === 0 ? formItemLayout : formItemLayoutWithOutLabel)}
                label={index === 0 ? 'Passengers' : ''}
                required={false}
                key={field.key}
              >
                <Form.Item
                  {...field}
                  validateTrigger={['onChange', 'onBlur']}
                  rules={[
                    {
                      required: true,
                      whitespace: true,
                      message: "Please input passenger's name or delete this field.",
                    },
                  ]}
                  noStyle
                >
                  <Input placeholder="passenger name" style={{ width: '60%' }} />
                </Form.Item>
                {fields.length > 1 ? (
                  <MinusCircleOutlined
                    className="dynamic-delete-button"
                    onClick={() => remove(field.name)}
                  />
                ) : null}
              </Form.Item>
            ))}
            <Form.Item>
              <Button
                type="dashed"
                onClick={() => add()}
                style={{ width: '60%' }}
                icon={<PlusOutlined />}
              >
                Add field
              </Button>
              <Button
                type="dashed"
                onClick={() => {
                  add('The head item', 0);
                }}
                style={{ width: '60%', marginTop: '20px' }}
                icon={<PlusOutlined />}
              >
                Add field at head
              </Button>
              <Form.ErrorList errors={errors} />
            </Form.Item>
          </>
        )}
      </Form.List>
      <Form.Item>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
      </Form.Item>
    </Form>
  );
};

export default App;
.dynamic-delete-button {
  position: relative;
  top: 4px;
  margin: 0 8px;
  color: #999;
  font-size: 24px;
  cursor: pointer;
  transition: all 0.3s;
}
.dynamic-delete-button:hover {
  color: #777;
}
.dynamic-delete-button[disabled] {
  cursor: not-allowed;
  opacity: 0.5;
}

动态增减嵌套字段

嵌套表单字段需要对 field 进行拓展，将 field.name 应用于控制字段。

TypeScript
JavaScript
import React from 'react';
import { MinusCircleOutlined, PlusOutlined } from '@ant-design/icons';
import { Button, Form, Input, Space } from 'antd';

const onFinish = (values: any) => {
  console.log('Received values of form:', values);
};

const App: React.FC = () => (
  <Form
    name="dynamic_form_nest_item"
    onFinish={onFinish}
    style={{ maxWidth: 600 }}
    autoComplete="off"
  >
    <Form.List name="users">
      {(fields, { add, remove }) => (
        <>
          {fields.map(({ key, name, ...restField }) => (
            <Space key={key} style={{ display: 'flex', marginBottom: 8 }} align="baseline">
              <Form.Item
                {...restField}
                name={[name, 'first']}
                rules={[{ required: true, message: 'Missing first name' }]}
              >
                <Input placeholder="First Name" />
              </Form.Item>
              <Form.Item
                {...restField}
                name={[name, 'last']}
                rules={[{ required: true, message: 'Missing last name' }]}
              >
                <Input placeholder="Last Name" />
              </Form.Item>
              <MinusCircleOutlined onClick={() => remove(name)} />
            </Space>
          ))}
          <Form.Item>
            <Button type="dashed" onClick={() => add()} block icon={<PlusOutlined />}>
              Add field
            </Button>
          </Form.Item>
        </>
      )}
    </Form.List>
    <Form.Item>
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

复杂的动态增减表单项

这个例子演示了一个表单中包含多个表单控件的情况。

TypeScript
JavaScript
import React from 'react';
import { MinusCircleOutlined, PlusOutlined } from '@ant-design/icons';
import { Button, Form, Input, Select, Space } from 'antd';

const { Option } = Select;

const areas = [
  { label: 'Beijing', value: 'Beijing' },
  { label: 'Shanghai', value: 'Shanghai' },
];

const sights = {
  Beijing: ['Tiananmen', 'Great Wall'],
  Shanghai: ['Oriental Pearl', 'The Bund'],
};

type SightsKeys = keyof typeof sights;

const App: React.FC = () => {
  const [form] = Form.useForm();

  const onFinish = (values: any) => {
    console.log('Received values of form:', values);
  };

  const handleChange = () => {
    form.setFieldsValue({ sights: [] });
  };

  return (
    <Form
      form={form}
      name="dynamic_form_complex"
      onFinish={onFinish}
      style={{ maxWidth: 600 }}
      autoComplete="off"
    >
      <Form.Item name="area" label="Area" rules={[{ required: true, message: 'Missing area' }]}>
        <Select options={areas} onChange={handleChange} />
      </Form.Item>
      <Form.List name="sights">
        {(fields, { add, remove }) => (
          <>
            {fields.map((field) => (
              <Space key={field.key} align="baseline">
                <Form.Item
                  noStyle
                  shouldUpdate={(prevValues, curValues) =>
                    prevValues.area !== curValues.area || prevValues.sights !== curValues.sights
                  }
                >
                  {() => (
                    <Form.Item
                      {...field}
                      label="Sight"
                      name={[field.name, 'sight']}
                      rules={[{ required: true, message: 'Missing sight' }]}
                    >
                      <Select disabled={!form.getFieldValue('area')} style={{ width: 130 }}>
                        {(sights[form.getFieldValue('area') as SightsKeys] || []).map((item) => (
                          <Option key={item} value={item}>
                            {item}
                          </Option>
                        ))}
                      </Select>
                    </Form.Item>
                  )}
                </Form.Item>
                <Form.Item
                  {...field}
                  label="Price"
                  name={[field.name, 'price']}
                  rules={[{ required: true, message: 'Missing price' }]}
                >
                  <Input />
                </Form.Item>

                <MinusCircleOutlined onClick={() => remove(field.name)} />
              </Space>
            ))}

            <Form.Item>
              <Button type="dashed" onClick={() => add()} block icon={<PlusOutlined />}>
                Add sights
              </Button>
            </Form.Item>
          </>
        )}
      </Form.List>
      <Form.Item>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
      </Form.Item>
    </Form>
  );
};

export default App;

嵌套结构与校验信息

name 属性支持嵌套数据结构。通过 validateMessages 或 message 自定义校验信息模板，模板内容可参考此处。

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, InputNumber } from 'antd';

const layout = {
  labelCol: { span: 8 },
  wrapperCol: { span: 16 },
};

/* eslint-disable no-template-curly-in-string */
const validateMessages = {
  required: '${label} is required!',
  types: {
    email: '${label} is not a valid email!',
    number: '${label} is not a valid number!',
  },
  number: {
    range: '${label} must be between ${min} and ${max}',
  },
};
/* eslint-enable no-template-curly-in-string */

const onFinish = (values: any) => {
  console.log(values);
};

const App: React.FC = () => (
  <Form
    {...layout}
    name="nest-messages"
    onFinish={onFinish}
    style={{ maxWidth: 600 }}
    validateMessages={validateMessages}
  >
    <Form.Item name={['user', 'name']} label="Name" rules={[{ required: true }]}>
      <Input />
    </Form.Item>
    <Form.Item name={['user', 'email']} label="Email" rules={[{ type: 'email' }]}>
      <Input />
    </Form.Item>
    <Form.Item name={['user', 'age']} label="Age" rules={[{ type: 'number', min: 0, max: 99 }]}>
      <InputNumber />
    </Form.Item>
    <Form.Item name={['user', 'website']} label="Website">
      <Input />
    </Form.Item>
    <Form.Item name={['user', 'introduction']} label="Introduction">
      <Input.TextArea />
    </Form.Item>
    <Form.Item wrapperCol={{ ...layout.wrapperCol, offset: 8 }}>
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

复杂一点的控件

这里演示 Form.Item 内有多个元素的使用方式。<Form.Item name="field" /> 只会对它的直接子元素绑定表单功能，例如直接包裹了 Input/Select。如果控件前后还有一些文案或样式装点，或者一个表单项内有多个控件，你可以使用内嵌的 Form.Item 完成。你可以给 Form.Item 自定义 style 进行内联布局，或者添加 noStyle 作为纯粹的无样式绑定组件（类似 3.x 中的 getFieldDecorator）。

TypeScript
JavaScript
import React from 'react';
import { Button, Form, Input, Select, Space, Tooltip, Typography } from 'antd';

const { Option } = Select;

const onFinish = (values: any) => {
  console.log('Received values of form: ', values);
};

const App: React.FC = () => (
  <Form
    name="complex-form"
    onFinish={onFinish}
    labelCol={{ span: 8 }}
    wrapperCol={{ span: 16 }}
    style={{ maxWidth: 600 }}
  >
    <Form.Item label="Username">
      <Space>
        <Form.Item
          name="username"
          noStyle
          rules={[{ required: true, message: 'Username is required' }]}
        >
          <Input style={{ width: 160 }} placeholder="Please input" />
        </Form.Item>
        <Tooltip title="Useful information">
          <Typography.Link href="#API">Need Help?</Typography.Link>
        </Tooltip>
      </Space>
    </Form.Item>
    <Form.Item label="Address">
      <Space.Compact>
        <Form.Item
          name={['address', 'province']}
          noStyle
          rules={[{ required: true, message: 'Province is required' }]}
        >
          <Select placeholder="Select province">
            <Option value="Zhejiang">Zhejiang</Option>
            <Option value="Jiangsu">Jiangsu</Option>
          </Select>
        </Form.Item>
        <Form.Item
          name={['address', 'street']}
          noStyle
          rules={[{ required: true, message: 'Street is required' }]}
        >
          <Input style={{ width: '50%' }} placeholder="Input street" />
        </Form.Item>
      </Space.Compact>
    </Form.Item>
    <Form.Item label="BirthDate" style={{ marginBottom: 0 }}>
      <Form.Item
        name="year"
        rules={[{ required: true }]}
        style={{ display: 'inline-block', width: 'calc(50% - 8px)' }}
      >
        <Input placeholder="Input birth year" />
      </Form.Item>
      <Form.Item
        name="month"
        rules={[{ required: true }]}
        style={{ display: 'inline-block', width: 'calc(50% - 8px)', margin: '0 8px' }}
      >
        <Input placeholder="Input birth month" />
      </Form.Item>
    </Form.Item>
    <Form.Item label=" " colon={false}>
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

自定义表单控件

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。

TypeScript
JavaScript
import React, { useState } from 'react';
import { Button, Form, Input, Select } from 'antd';

const { Option } = Select;

type Currency = 'rmb' | 'dollar';

interface PriceValue {
  number?: number;
  currency?: Currency;
}

interface PriceInputProps {
  value?: PriceValue;
  onChange?: (value: PriceValue) => void;
}

const PriceInput: React.FC<PriceInputProps> = ({ value = {}, onChange }) => {
  const [number, setNumber] = useState(0);
  const [currency, setCurrency] = useState<Currency>('rmb');

  const triggerChange = (changedValue: { number?: number; currency?: Currency }) => {
    onChange?.({ number, currency, ...value, ...changedValue });
  };

  const onNumberChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const newNumber = parseInt(e.target.value || '0', 10);
    if (Number.isNaN(number)) {
      return;
    }
    if (!('number' in value)) {
      setNumber(newNumber);
    }
    triggerChange({ number: newNumber });
  };

  const onCurrencyChange = (newCurrency: Currency) => {
    if (!('currency' in value)) {
      setCurrency(newCurrency);
    }
    triggerChange({ currency: newCurrency });
  };

  return (
    <span>
      <Input
        type="text"
        value={value.number || number}
        onChange={onNumberChange}
        style={{ width: 100 }}
      />
      <Select
        value={value.currency || currency}
        style={{ width: 80, margin: '0 8px' }}
        onChange={onCurrencyChange}
      >
        <Option value="rmb">RMB</Option>
        <Option value="dollar">Dollar</Option>
      </Select>
    </span>
  );
};

const App: React.FC = () => {
  const onFinish = (values: any) => {
    console.log('Received values from form: ', values);
  };

  const checkPrice = (_: any, value: { number: number }) => {

表单数据存储于上层组件

通过 onFieldsChange 和 fields，可以把表单的数据存储到上层组件或者 Redux、dva 中，更多可参考 rc-field-form 示例。

注意： 将表单数据存储于外部容器并非好的实践，如无必要请避免使用。

TypeScript
JavaScript
import React, { useState } from 'react';
import { Form, Input, Typography } from 'antd';

const { Paragraph } = Typography;

interface FieldData {
  name: string | number | (string | number)[];
  value?: any;
  touched?: boolean;
  validating?: boolean;
  errors?: string[];
}

interface CustomizedFormProps {
  onChange: (fields: FieldData[]) => void;
  fields: FieldData[];
}

const CustomizedForm: React.FC<CustomizedFormProps> = ({ onChange, fields }) => (
  <Form
    name="global_state"
    layout="inline"
    fields={fields}
    onFieldsChange={(_, allFields) => {
      onChange(allFields);
    }}
  >
    <Form.Item
      name="username"
      label="Username"
      rules={[{ required: true, message: 'Username is required!' }]}
    >
      <Input />
    </Form.Item>
  </Form>
);

const App: React.FC = () => {
  const [fields, setFields] = useState<FieldData[]>([{ name: ['username'], value: 'Ant Design' }]);

  return (
    <>
      <CustomizedForm
        fields={fields}
        onChange={(newFields) => {
          setFields(newFields);
        }}
      />
      <Paragraph style={{ maxWidth: 440, marginTop: 24 }}>
        <pre style={{ border: 'none' }}>{JSON.stringify(fields, null, 2)}</pre>
      </Paragraph>
    </>
  );
};

export default App;

多表单联动

通过 Form.Provider 在表单间处理数据。本例子中，Modal 的确认按钮在 Form 之外，通过 form.submit 方法调用表单提交功能。反之，则推荐使用 <Button htmlType="submit" /> 调用 web 原生提交逻辑。

TypeScript
JavaScript
import React, { useEffect, useRef, useState } from 'react';
import { SmileOutlined, UserOutlined } from '@ant-design/icons';
import { Avatar, Button, Form, Input, InputNumber, Modal, Typography } from 'antd';
import type { FormInstance } from 'antd/es/form';

const layout = {
  labelCol: { span: 8 },
  wrapperCol: { span: 16 },
};

const tailLayout = {
  wrapperCol: { offset: 8, span: 16 },
};

interface UserType {
  name: string;
  age: string;
}

interface ModalFormProps {
  open: boolean;
  onCancel: () => void;
}

// reset form fields when modal is form, closed
const useResetFormOnCloseModal = ({ form, open }: { form: FormInstance; open: boolean }) => {
  const prevOpenRef = useRef<boolean>();
  useEffect(() => {
    prevOpenRef.current = open;
  }, [open]);
  const prevOpen = prevOpenRef.current;

  useEffect(() => {
    if (!open && prevOpen) {
      form.resetFields();
    }
  }, [form, prevOpen, open]);
};

const ModalForm: React.FC<ModalFormProps> = ({ open, onCancel }) => {
  const [form] = Form.useForm();

  useResetFormOnCloseModal({
    form,
    open,
  });

  const onOk = () => {
    form.submit();
  };

  return (
    <Modal title="Basic Drawer" open={open} onOk={onOk} onCancel={onCancel}>
      <Form form={form} layout="vertical" name="userForm">
        <Form.Item name="name" label="User Name" rules={[{ required: true }]}>
          <Input />
        </Form.Item>
        <Form.Item name="age" label="User Age" rules={[{ required: true }]}>
          <InputNumber />
        </Form.Item>
      </Form>
    </Modal>
  );
};

const App: React.FC = () => {
  const [open, setOpen] = useState(false);

  const showUserModal = () => {
    setOpen(true);
  };

  const hideUserModal = () => {
    setOpen(false);
  };

  const onFinish = (values: any) => {
    console.log('Finish:', values);
  };

  return (
    <Form.Provider
      onFormFinish={(name, { values, forms }) => {
        if (name === 'userForm') {
          const { basicForm } = forms;
          const users = basicForm.getFieldValue('users') || [];
          basicForm.setFieldsValue({ users: [...users, values] });
          setOpen(false);
        }
      }}
    >
      <Form {...layout} name="basicForm" onFinish={onFinish} style={{ maxWidth: 600 }}>
        <Form.Item name="group" label="Group Name" rules={[{ required: true }]}>
          <Input />
        </Form.Item>
        <Form.Item
          label="User List"
          shouldUpdate={(prevValues, curValues) => prevValues.users !== curValues.users}
        >
          {({ getFieldValue }) => {
            const users: UserType[] = getFieldValue('users') || [];
            return users.length ? (
              <ul>
                {users.map((user) => (
                  <li key={user.name} className="user">
                    <Avatar icon={<UserOutlined />} />
                    {user.name} - {user.age}
                  </li>
                ))}
              </ul>
            ) : (
              <Typography.Text className="ant-form-text" type="secondary">
                ( <SmileOutlined /> No user yet. )
              </Typography.Text>
            );
          }}
        </Form.Item>
        <Form.Item {...tailLayout}>
          <Button htmlType="submit" type="primary">
            Submit
          </Button>
          <Button htmlType="button" style={{ margin: '0 8px' }} onClick={showUserModal}>

      <ModalForm open={open} onCancel={hideUserModal} />

  );
};

内联登录栏

内联登录栏，常用在顶部导航栏中。

TypeScript
JavaScript
import React, { useEffect, useState } from 'react';
import { LockOutlined, UserOutlined } from '@ant-design/icons';
import { Button, Form, Input } from 'antd';

const App: React.FC = () => {
  const [form] = Form.useForm();
  const [, forceUpdate] = useState({});

  // To disable submit button at the beginning.
  useEffect(() => {
    forceUpdate({});
  }, []);

  const onFinish = (values: any) => {
    console.log('Finish:', values);
  };

  return (
    <Form form={form} name="horizontal_login" layout="inline" onFinish={onFinish}>
      <Form.Item
        name="username"
        rules={[{ required: true, message: 'Please input your username!' }]}
      >
        <Input prefix={<UserOutlined className="site-form-item-icon" />} placeholder="Username" />
      </Form.Item>
      <Form.Item
        name="password"
        rules={[{ required: true, message: 'Please input your password!' }]}
      >
        <Input
          prefix={<LockOutlined className="site-form-item-icon" />}
          type="password"
          placeholder="Password"
        />
      </Form.Item>
      <Form.Item shouldUpdate>
        {() => (
          <Button
            type="primary"
            htmlType="submit"
            disabled={
              !form.isFieldsTouched(true) ||
              !!form.getFieldsError().filter(({ errors }) => errors.length).length
            }
          >
            Log in
          </Button>
        )}
      </Form.Item>
    </Form>
  );
};

export default App;

普通的登录框，可以容纳更多的元素。

Search Result List

三列栅格式的表单排列方式，常用于数据表格的高级搜索。

有部分定制的样式代码，由于输入标签长度不确定，需要根据具体情况自行调整。

弹出层中的新建表单

当用户访问一个展示了某个列表的页面，想新建一项但又不想跳转页面时，可以用 Modal 弹出一个表单，用户填写必要信息后创建新的项。

🛎️ 想要 3 分钟实现？试试 ProForm 的 Modal 表单！

TypeScript
JavaScript
import React, { useState } from 'react';
import { Button, Form, Input, Modal, Radio } from 'antd';

interface Values {
  title: string;
  description: string;
  modifier: string;
}

interface CollectionCreateFormProps {
  open: boolean;
  onCreate: (values: Values) => void;
  onCancel: () => void;
}

const CollectionCreateForm: React.FC<CollectionCreateFormProps> = ({
  open,
  onCreate,
  onCancel,
}) => {
  const [form] = Form.useForm();
  return (
    <Modal
      open={open}
      title="Create a new collection"
      okText="Create"
      cancelText="Cancel"
      onCancel={onCancel}
      onOk={() => {
        form
          .validateFields()
          .then((values) => {
            form.resetFields();
            onCreate(values);
          })
          .catch((info) => {
            console.log('Validate Failed:', info);
          });
      }}
    >
      <Form
        form={form}
        layout="vertical"
        name="form_in_modal"
        initialValues={{ modifier: 'public' }}
      >
        <Form.Item
          name="title"
          label="Title"
          rules={[{ required: true, message: 'Please input the title of collection!' }]}
        >
          <Input />
        </Form.Item>
        <Form.Item name="description" label="Description">
          <Input type="textarea" />
        </Form.Item>
        <Form.Item name="modifier" className="collection-create-form_last-form-item">
          <Radio.Group>
            <Radio value="public">Public</Radio>
            <Radio value="private">Private</Radio>
          </Radio.Group>
        </Form.Item>
      </Form>
    </Modal>
  );
};

const App: React.FC = () => {
  const [open, setOpen] = useState(false);

  const onCreate = (values: any) => {
    console.log('Received values of form: ', values);
    setOpen(false);
  };

  return (
    <div>
      <Button
        type="primary"
        onClick={() => {
          setOpen(true);
        }}
      >
        New Collection
      </Button>
      <CollectionCreateForm
        open={open}
        onCreate={onCreate}

};

export default App;
.collection-create-form_last-form-item {

时间类控件

时间类组件的 value 类型为 dayjs 对象，所以在提交服务器前需要预处理。

TypeScript
JavaScript
import React from 'react';
import { Button, DatePicker, Form, TimePicker } from 'antd';

const { RangePicker } = DatePicker;

const formItemLayout = {
  labelCol: {
    xs: { span: 24 },
    sm: { span: 8 },
  },
  wrapperCol: {
    xs: { span: 24 },
    sm: { span: 16 },
  },
};

const config = {
  rules: [{ type: 'object' as const, required: true, message: 'Please select time!' }],
};

const rangeConfig = {
  rules: [{ type: 'array' as const, required: true, message: 'Please select time!' }],
};

const onFinish = (fieldsValue: any) => {
  // Should format date value before submit.
  const rangeValue = fieldsValue['range-picker'];
  const rangeTimeValue = fieldsValue['range-time-picker'];
  const values = {
    ...fieldsValue,
    'date-picker': fieldsValue['date-picker'].format('YYYY-MM-DD'),
    'date-time-picker': fieldsValue['date-time-picker'].format('YYYY-MM-DD HH:mm:ss'),
    'month-picker': fieldsValue['month-picker'].format('YYYY-MM'),
    'range-picker': [rangeValue[0].format('YYYY-MM-DD'), rangeValue[1].format('YYYY-MM-DD')],
    'range-time-picker': [
      rangeTimeValue[0].format('YYYY-MM-DD HH:mm:ss'),
      rangeTimeValue[1].format('YYYY-MM-DD HH:mm:ss'),
    ],
    'time-picker': fieldsValue['time-picker'].format('HH:mm:ss'),
  };
  console.log('Received values of form: ', values);
};

const App: React.FC = () => (
  <Form
    name="time_related_controls"
    {...formItemLayout}
    onFinish={onFinish}
    style={{ maxWidth: 600 }}
  >
    <Form.Item name="date-picker" label="DatePicker" {...config}>
      <DatePicker />
    </Form.Item>
    <Form.Item name="date-time-picker" label="DatePicker[showTime]" {...config}>
      <DatePicker showTime format="YYYY-MM-DD HH:mm:ss" />
    </Form.Item>
    <Form.Item name="month-picker" label="MonthPicker" {...config}>
      <DatePicker picker="month" />
    </Form.Item>
    <Form.Item name="range-picker" label="RangePicker" {...rangeConfig}>
      <RangePicker />
    </Form.Item>
    <Form.Item name="range-time-picker" label="RangePicker[showTime]" {...rangeConfig}>
      <RangePicker showTime format="YYYY-MM-DD HH:mm:ss" />
    </Form.Item>
    <Form.Item name="time-picker" label="TimePicker" {...config}>
      <TimePicker />
    </Form.Item>
    <Form.Item wrapperCol={{ xs: { span: 24, offset: 0 }, sm: { span: 16, offset: 8 } }}>
      <Button type="primary" htmlType="submit">
        Submit
      </Button>
    </Form.Item>
  </Form>
);

export default App;

自行处理表单数据

Form 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，可以选择自行处理数据。

TypeScript
JavaScript
import React, { useState } from 'react';
import { Form, InputNumber } from 'antd';

type ValidateStatus = Parameters<typeof Form.Item>[0]['validateStatus'];

const validatePrimeNumber = (
  number: number,
): {
  validateStatus: ValidateStatus;
  errorMsg: string | null;
} => {
  if (number === 11) {
    return {
      validateStatus: 'success',
      errorMsg: null,
    };
  }
  return {
    validateStatus: 'error',
    errorMsg: 'The prime between 8 and 12 is 11!',
  };
};

const formItemLayout = {
  labelCol: { span: 7 },
  wrapperCol: { span: 12 },
};

const tips =
  'A prime is a natural number greater than 1 that has no positive divisors other than 1 and itself.';

const App: React.FC = () => {
  const [number, setNumber] = useState<{
    value: number;
    validateStatus?: ValidateStatus;
    errorMsg?: string | null;
  }>({ value: 11 });

  const onNumberChange = (value: number) => {
    setNumber({
      ...validatePrimeNumber(value),
      value,
    });
  };

  return (
    <Form style={{ maxWidth: 600 }}>
      <Form.Item
        {...formItemLayout}
        label="Prime between 8 & 12"
        validateStatus={number.validateStatus}
        help={number.errorMsg || tips}
      >
        <InputNumber min={8} max={12} value={number.value} onChange={onNumberChange} />
      </Form.Item>
    </Form>
  );
};

export default App;

自定义校验

我们提供了 validateStatus help hasFeedback 等属性，你可以不通过 Form 自己定义校验的时机和内容。

validateStatus: 校验状态，可选 'success', 'warning', 'error', 'validating'。
hasFeedback：用于给输入框添加反馈图标。
help：设置校验文案。

TypeScript
JavaScript
import React from 'react';
import { SmileOutlined } from '@ant-design/icons';
import {
  Cascader,
  DatePicker,
  Form,
  Input,
  InputNumber,
  Mentions,
  Select,
  TimePicker,
  TreeSelect,
} from 'antd';

const { Option } = Select;

const formItemLayout = {
  labelCol: {
    xs: { span: 24 },
    sm: { span: 6 },
  },
  wrapperCol: {
    xs: { span: 24 },
    sm: { span: 14 },
  },
};

const App: React.FC = () => (
  <Form {...formItemLayout} style={{ maxWidth: 600 }}>
    <Form.Item
      label="Fail"
      validateStatus="error"
      help="Should be combination of numbers & alphabets"
    >
      <Input placeholder="unavailable choice" id="error" />
    </Form.Item>

    <Form.Item label="Warning" validateStatus="warning">
      <Input placeholder="Warning" id="warning" prefix={<SmileOutlined />} />
    </Form.Item>

    <Form.Item
      label="Validating"
      hasFeedback
      validateStatus="validating"
      help="The information is being validated..."
    >
      <Input placeholder="I'm the content is being validated" id="validating" />
    </Form.Item>

    <Form.Item label="Success" hasFeedback validateStatus="success">
      <Input placeholder="I'm the content" id="success" />
    </Form.Item>

    <Form.Item label="Warning" hasFeedback validateStatus="warning">
      <Input placeholder="Warning" id="warning2" />
    </Form.Item>

    <Form.Item
      label="Fail"
      hasFeedback
      validateStatus="error"
      help="Should be combination of numbers & alphabets"
    >
      <Input placeholder="unavailable choice" id="error2" />
    </Form.Item>

动态校验规则

根据不同情况执行不同的校验规则。
