Question

我正在尝试根据Dan Abramov here的建议实施redux重置状态操作。我已经设置了我的减速器和存储器，如下所示：

Index.js：

import {applyMiddleware,createStore} from 'redux';
import combineReducers from './reducers/index';
import {wrapStore,alias} from 'react-chrome-redux';
import thunk from 'redux-thunk';
import aliases from './aliases/aliases';

const combineAppReducers = ( state, action ) => {
  if ( action.type === 'LOG_OUT' ) {
    state = undefined;
  }

  return combineReducers(state, action)
}

const middlewares = [alias(aliases), thunk];

const store = createStore(combineAppReducers,applyMiddleware(...middlewares));

wrapStore(store, {
  portName: 'example'
});

Reducers.js：

import {combineReducers} from 'redux';
import userAuthReducer from './userAuthReducer';
import manageTeamsReducer from './manageTeamsReducer';

function lastAction(state = null, action) {
  return action;
}

export default combineReducers({
  userAuthReducer,manageTeamsReducer,lastAction
});

看起来我已经正确设置了一切，但应用程序没有重置状态，有人能找到我出错的地方吗？

这是另一篇关于它的文章，我更加密切关注：

工作正常。你可以查看我的代码片段。你能上传错误日志吗？

function lastAction(state = null, action) {
  return action;
}

function counter(state = 0, action) {
  if ( action.type === 'INC' ) {
      return state+1;
  }
 
  return state;
}

const  combineAppReducers = Redux.combineReducers({
  lastAction,
  counter
});

const combineReducers = ( state, action ) => {
  if ( action.type === 'LOG_OUT' ) {
    state = undefined;
  }
  return combineAppReducers(state, action)
}

const store = Redux.createStore(combineReducers);

const root = document.createElement('ul');
document.body.append(root);
let unsubscribe = store.subscribe(() =>{
  const li = document.createElement('li');
  li.append(store.getState().counter);
  root.append(li);
})

store.dispatch({type: 'INC'});
store.dispatch({type: 'INC'});
store.dispatch({type: 'INC'});
store.dispatch({type: 'LOG_OUT'});
store.dispatch({type: 'INC'});
