如何使用React应用程序中的redux工具包更新不同reducer (切片)中的嵌套项

npm install redux react-redux

import { createStore } from 'redux';
import rootReducer from './reducers';

const store = createStore(rootReducer);

import { connect } from 'react-redux';

const MyComponent = ({ nestedItem, updateNestedItem }) => {
  // 使用nestedItem和updateNestedItem进行操作
};

const mapStateToProps = (state) => ({
  nestedItem: state.reducerName.nestedItem,
});

const mapDispatchToProps = (dispatch) => ({
  updateNestedItem: (newValue) => dispatch({ type: 'UPDATE_NESTED_ITEM', payload: newValue }),
});

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

const initialState = {
  nestedItem: {
    value: 'initial value',
  },
};

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case 'UPDATE_NESTED_ITEM':
      return {
        ...state,
        nestedItem: {
          ...state.nestedItem,
          value: action.payload,
        },
      };
    default:
      return state;
  }
};

export default reducer;

const MyComponent = ({ nestedItem, updateNestedItem }) => {
  const handleUpdate = () => {
    updateNestedItem('new value');
  };

  return (
    <div>
      <p>{nestedItem.value}</p>
      <button onClick={handleUpdate}>Update Nested Item</button>
    </div>
  );
};
