在两个reducers之间共享状态(React +Redux)

// reducers.js
import { combineReducers } from 'redux';

// 第一个reducer
const reducer1 = (state = {}, action) => {
  switch (action.type) {
    case 'ACTION_TYPE_1':
      return {
        ...state,
        // 更新状态
      };
    default:
      return state;
  }
};

// 第二个reducer
const reducer2 = (state = {}, action) => {
  switch (action.type) {
    case 'ACTION_TYPE_2':
      return {
        ...state,
        // 更新状态
      };
    default:
      return state;
  }
};

// 根reducer，将多个reducers组合成一个
const rootReducer = combineReducers({
  reducer1,
  reducer2,
});

export default rootReducer;

// MyComponent.js
import React from 'react';
import { connect } from 'react-redux';

const MyComponent = ({ sharedState, updateSharedState }) => {
  // 使用共享状态
  // 更新共享状态

  return (
    // 组件的JSX代码
  );
};

const mapStateToProps = (state) => ({
  sharedState: state.reducer1.sharedState, // 获取共享状态
});

const mapDispatchToProps = (dispatch) => ({
  updateSharedState: (newState) => {
    dispatch({ type: 'ACTION_TYPE_1', payload: newState }); // 更新共享状态
  },
});

export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);
