基于antd@5.x封装Form.List组件

使用案例

const initFormState = {
	formList1: [
		{
			start: '测试',
			end: '100',
		},
		{
			start: 'abc',
			end: 'value',
		},
	],
	formList2: [
		{
			start: '测试2',
			end: '6',
		},
		{
			start: 'vxcv',
			end: 'jksdhfjk',
		},
	],
};


<Form
	form={form}
	onFinish={onFinish}
	autoComplete='off'
	initialValues={initFormState}
>
	<FormList
		name='formList1'
		rules={[
			{
				validator(_, names) {
					if (!names || !names.length) {
						return Promise.reject(new Error('至少填写一组数据！'));
					}

					return Promise.resolve();
				},
			},
		]}
		dataSource={[
			{ 
			    label: 'start', name: 'label',
			    component: <Input />,
			    rules: [{ required: true, message: '请输入' }],
			},
			{ label: 'end', name: 'value', component: <Input /> },
		]}
	/>
	<FormList
		name='formList2'
		dataSource={[
			{ label: 'start', name: 'label', component: <Input /> },
			{ label: 'end', name: 'value', component: <Input /> },
		]}
	/>
	<Form.Item>
		<Button type='primary' htmlType='submit'>
			Submit
		</Button>
	</Form.Item>
</Form>

import React from 'react';
import { Form, Button, Space } from 'antd';

	return (

			{(fields, { add, remove }) => {
				return (

	);
}

FormList.defaultProps = {
