Benötigen Sie Anzeigedaten, nachdem AJAX-Aufruf ausgeführt wird.Warten auf AJAX-Anforderung (React, Redux)
Meine Reducer:
import { INCOME_PROFILE } from '../actionTypes'
import Immutable from 'immutable'
const initialUserState = [];
const profileReducer = function(state = initialUserState, action) {
//console.log('actiondata in reducer:' + action.data + action.type);
switch(action.type) {
case 'INCOME_PROFILE_IS_LOADING':
return Object.assign({}, state, { hh: action.hasFetched });
case 'INCOME_PROFILE':
return Object.assign({}, state, { course_list: action.data, hh: action.hasFetched });
default:
return state;
}
}
export default profileReducer
Meine Aktion Schöpfer:
export function GET_ITEM_REQUEST() {
return {
type: INCOME_PROFILE_IS_LOADING,
hasFetched: false,
}
}
function receiveData(json) {
return{
type: INCOME_PROFILE,
data: json,
hasFetched: true
}
};
export function IncomeProfileList() {
return dispatch => {
return (
axios.post(Api.getURI("profile"),{}, {
headers: { 'X-Authenticated-Userid': '[email protected]' }
}).then(function (response) {
//console.log(response.data);
dispatch(receiveData(response.data.body));
})
.catch((error) => {
console.log(error);
})
)
}
}
Meine Komponente:
class IncomeProfile extends Component {
constructor(props) {
super(props)
}
componentDidMount() {
this.props.IncomeListProfile();
}
render() {
console.log(this.props.isloading);
if (this.props.isloading) {
return <p>Sorry! There was an error loading the items</p>;
}
}
}
const mapDispatchToProps = function(dispatch) {
return {
IncomeListProfile:() => dispatch(IncomeProfileList())
}
}
const mapStateToProps = function(state) {
//var mystore = state.toJS()
var mystore = state.getIn(['incomeProfileList'])['course_list'];
var mystored = state.getIn(['incomeProfileList']);
console.log(mystored.hh);
var copy = Object.assign({}, mystore);
return {
items: copy.course_list,
isloading: mystored.hh
};
}
Ich brauche weiter: Während Antwort nicht fertig, ich habe keine Notwendigkeit, Daten anzuzeigen . Bedingung, wenn jetzt nicht funktioniert
console.log beim ersten Mal undefined - denke, muss falsch sein, aber es nicht falsch. und das zweite Mal wird es wahr.
