我正在将Redux集成到我的React Native应用程序中。
我一直无法将状态传递给我的组件,并意识到它是因为初始状态以' 0'键开头,例如
{
'0': {
key: 'value'
}
}
即。它似乎是一个阵列。
如果我的connect
导出:
export default connect(state => ({
key: state.key,
reduxState: state
}),
(dispatch) => ({
actions: bindActionCreators(MyActions, dispatch)
})
)(MyReduxApp);
key
始终未定义,但reduxState
成功传递下来。 (当然不建议将整个州送下来)
根组件:
import React, { Component } from 'react-native';
import { createStore, applyMiddleware, combineReducers } from 'redux';
import { Provider } from 'react-redux';
import DataReducer from '../Reducers/Data';
import MyRedApp from './JustTunerApp';
const createStoreWithMiddleware = applyMiddleware(thunk)(createStore);
const reducer = combineReducers([DataReducer]); // ready for more reducers..
// const store = createStoreWithMiddleware(reducer);
const store = createStore(reducer);
export default class App extends Component {
render() {
console.log ("store.getState:")
console.log (store.getState())
return (
<Provider store={store}>
<MyReduxApp />
</Provider>
);
}
}
我的减速机看起来像:
const initialState = {
key : "value"
};
export default function key(state = initialState, action = {}) {
switch (action.type) {
// ...
default:
return state;
}
}
商店是否以数组形式返回?我应该如何将其传递给connect
方法?
如果我将其作为key: state[0].key
传递,那么它可以正常工作,但根据我见过的所有示例,这看起来并不合适。
答案 0 :(得分:1)
我应该早点发布根组件......这样做了。
const reducer = combineReducers([DataReducer])
应该是
const reducer = combineReducers({DataReducer})
这里的教训是不要急于查看文档!
