因此,我正在尝试将 ExtReact 中的商店解析为 Reducer 中的组件(按照以下说明操作:http ://docs.sencha.com/extreact/6.5.0/guides/extreact_stores_in_flux.html#extreact_stores_in_flux__-_option_1__in_the_redux_store )。但似乎,我无法从减速器传递状态(即,我正在传递存储和数据的未定义状态),即使当我 consol.log 存储和减速器中的数据对象时,我得到了具体的值。值得一提的是,reducer 被添加到 index.js combineReducer 函数中,因此可以读取它,这不是问题。
因此,这些是代码中最重要的部分:
- 减速器:
export function usershortcuts(state = initialState, action){
switch(action.type){
case types.USER_SHORTCUT_FETCH_DATA_SUCCESS:{
console.log("User shortcut store = state.userShortCutStore); // I am getting a concrete result
state.userShortCutData = state.userShortCutStore.getData();
console.log("User shortcut data = " + state.userShortCutData); //I am getting a concrete result
return{...state};
}
default:{
console.log(state.userShortCutStore);
return {...state};
}
}
}
- 初始状态:
export default {
/* User shortcuts store. */
userShortCutStore: userShortcutStore,
userShortCutData: []
}
- 索引.js:
const store = configureStore();
store.dispatch(usershortcutFetchDataThroughStore());
launch(
<Provider store = {store}>
<HashRouter>
<Switch>
{/* <Route path="/" name="Home" component={TextEditor}/>*/}
<Route path="/" name="Home" component={Full}/>
</Switch>
</HashRouter>
</Provider>
);
- ShortcutComponent 在 Header 里面,在里面
class ShortcutComponent extends Component{
constructor(props){
super(props);
this.state={
userShortCutStore: null,
userShortCutData: []
}
}
componentDidMount(){
this.setState({
userShortCutStore: this.props.userShortCutStore,
userShortCutData: this.props.userShortCutData
})
}
render(){
const userShortCutStore = this.state.userShortCutStore;
const userShortCutData = this.state.userShortCutData;
console.log("Store = " + userShortCutStore); //undefined
console.log("User shortcut data = " + userShortCutData); //undefined
return(
/* .... */
)
}
}
const mapStateToProps = (state) => {
return {
userShortCutStore: state.userShortCutStore,
userShortCutData: state.userShortCutData
}
};
export default connect(mapStateToProps) (ShortcutComponent);
