使用React.js和redux从<Field> onSubmit获取值。

import React from 'react';
import { connect } from 'react-redux';
import { updateFieldValue } from './actions';

class MyForm extends React.Component {
  handleSubmit = (event) => {
    event.preventDefault();
    const fieldValue = event.target.elements.field.value;
    this.props.updateFieldValue(fieldValue);
  }

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <label>
          Field:
          <input type="text" name="field" />
        </label>
        <button type="submit">Submit</button>
      </form>
    );
  }
}

const mapDispatchToProps = {
  updateFieldValue,
};

export default connect(null, mapDispatchToProps)(MyForm);
