动态获取redux表单的字段

// 定义表单状态对象
const initialState = {
  fields: {
    username: '',
    password: '',
    email: '',
    // 其他字段...
  }
};

// 定义reducer
const formReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'UPDATE_FORM_FIELD':
      return {
        ...state,
        fields: {
          ...state.fields,
          [action.fieldName]: action.fieldValue
        }
      };
    // 其他reducer逻辑...
    default:
      return state;
  }
};

// 组件中使用表单状态对象
import React from 'react';
import { connect } from 'react-redux';

const MyForm = ({ fields }) => {
  // 动态获取字段的值
  const usernameValue = fields.username;
  const passwordValue = fields.password;
  const emailValue = fields.email;
  // 其他字段...

  return (
    <form>
      <input type="text" value={usernameValue} />
      <input type="password" value={passwordValue} />
      <input type="email" value={emailValue} />
      {/* 其他字段... */}
    </form>
  );
};

// 映射表单状态对象到组件的props
const mapStateToProps = (state) => ({
  fields: state.form.fields
});

export default connect(mapStateToProps)(MyForm);
