反应：不获取字段的值

Question

我对地址字段进行以下实现。这将是一个可重复使用的组件，可以与任何形式一起使用以显示地址字段，例如城市，邮政编码等。

现在，我可以使用来以任何形式查看地址字段。

import Address from '../Address';// something

但是，每当我提交表单时，都不会在表单的请求中获得这些字段值。我刚刚开始学习React。以下是代码。

import React, { Fragment, Component } from "react";
import { FormattedMessage, injectIntl } from "react-intl";
import {
  Input,
  Column,
  FormGroup,
  FormText,
  FormFeedback,
  Label
} from "@companyname/components";

class Address extends Component {
  constructor(props) {
    super(props);
  }
  render() {
    return (
      <Fragment>
        <FormGroup row className="mt-3">
          <Label for="country" sm={2} className="input-is-required text-right">
            <FormattedMessage id="account.registration.form.label.country" />
          </Label>
          <Column sm={3}>
            <Input
              defaultValue={this.props.country}
              id="country"
              name="country"
              onChange={this.props.handleChange}
              required
              type="select"
              disabled={this.props.loading}
            >
              <option value="NL">Nederland</option>
              <option value="BE">Belgie</option>
