reactjs

Question

我正在使用 reactjs。节点：版本 14

我正在开发 core-ui-react-template.

更新 ./store 文件后边栏无法使用。我把商店文件和index.js文件的内容放在下面。

原网站core.io 我已经为此工作了几天，但我无法得到任何结果。找不到哪里错了

index.js

import 'react-app-polyfill/ie11'; // For IE 11 support
import 'react-app-polyfill/stable';
import './polyfill'
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import * as serviceWorker from './serviceWorker';
import { icons } from './assets/icons'
import store from './store'
import { transitions, positions, Provider as AlertProvider } from 'react-alert'
import AlertTemplate from 'react-alert-template-basic'
import {Provider} from 'react-redux';
import ReactNotification from 'react-notifications-component';
import 'react-notifications-component/dist/theme.css'

React.icons = icons;

const options = {
  position: positions.BOTTOM_RIGHT,
  timeout: 5000,
  offset: '1px',
  transition: transitions.SCALE,
};

console.log(store.getState());

ReactDOM.render(
  <Provider store={store}>

      <AlertProvider template={AlertTemplate} {...options}>

        <ReactNotification/>
        <App/>

      </AlertProvider>
  </Provider>,
  document.getElementById('root')
);
serviceWorker.unregister();

./store.js

import {applyMiddleware, combineReducers, compose, createStore} from "redux";
import customerReducer from "./components/helpers/reducers/customerReducer";
import userReducer from "./components/helpers/reducers/userReducer";
import appointmentsReducer from "./components/helpers/reducers/appointmenstReducer";
import thunk from "redux-thunk";


const initialState = {
  sidebarShow: 'responsive'
};

const changeStateReducer = (state = initialState, { type, ...rest }) => {
  switch (type) {
    case 'set':
      return {...state, ...rest };
    default:
      return state
  }
};
const rootReducers = combineReducers({
  customerInfo: customerReducer,
  account_profile: userReducer,
  appointmentsList: appointmentsReducer,
  changeState: changeStateReducer
});
const allEnhancers = compose(
  applyMiddleware(thunk)
);
const store = createStore(
  rootReducers,
  allEnhancers
);
export default store

如你所知，我使用 core-ui-react 模板。下面有个link。但是更新 ./store 文件后，当我在“const sidebarShow = useSelector (state => state.sidebarShow)[= TheHeader 文件中的 38=]" 行。

https://github.com/coreui/coreui-free-react-admin-template/blob/master/src/containers/TheHeader.js

我认为“useSelector (state => state.sidebarShow)”在这里没有得到函数。起源于此。

查看 combineReducers 的工作原理：https://redux.js.org/api/combinereducers

您的选择器应该是：

const sidebarShow = useSelector(state => state.changeState.sidebarShow)

您会注意到 changeState 不是一个很好的键名，但这是另一个问题:)

reactjs - 商店更新后边栏不工作

reactjs - sidebar not working after store update

node.js

react-redux

core-ui
