React Antd 一个formItem中多个Input的验证方法

实现效果如下：

当点击按钮的时候 对一个FormItem里的多个input/或者是input和select进行校验  同时通过Rol/Col实现布局

Rselect/input组件封装的组件如下field.js:

import React from 'react';
import { Select, Input, Row, Col } from 'antd';
import _ from 'underscore';
import './index.less';
const Option = Select.Option;
const uiPrefix = "certificate-field"

      cities: [],//城市下拉框列表

      cityId: undefined,
      warrantNumber: undefined,
    };
  }
  static defaultProps = {
    cities: [],
    yearlists: [],
    hasYear: true,
    hasCity: true,

    hasWarrantNum: true,
    years: (new Date()).getFullYear(),
    cityId: 1,
  }

    let { years, cityId, warrantNumber } = value;
    years = years ? ('' + years) : undefined;
    cityId = cityId ? ('' + cityId) : undefined;
    warrantNumber = warrantNumber ? ('' + warrantNumber) : undefined

    return { years, cityId, warrantNumber };
  }

需要调用入口页面index.js:

import React from "react";
import { Form, Input, Button, Radio, message, Modal } from "antd";
import { CertificateField } from "components";
class Schhouse extends React.Component {
    onSearchHandle = () => {
        //注意validateFields里的fields,要和getFieldDecorator中的fields保持一致 否则拿不到值
        this.props.form.validateFields(["fields"], (err, fieldsValue) => {
            console.log(fieldsValue, "fieldsValue")
            if (err) {
                return;
            }
        })
    }

    render() {
        const { getFieldDecorator } = this.props.form;
        return (
            <>
                <Form>
                    <Form.Item label="标签">
                        {getFieldDecorator('fields', {
                            rules: [{ required: true, message: '请输入标签对应内容' }],
                        })(
                            <CertificateField />
                        )}
                    </Form.Item>
                    <Form.Item>
                        <Button type="primary" htmlType="submit" onClick={this.onSearchHandle.bind(this)}>
                            查询并办理
                        </Button>
                    </Form.Item>
                </Form>
            </>
        )
    }
}

export default Form.create()(Schhouse);

非常完美！！！！！！！！
