问题描述
我有一个 react-big-calendar (父容器)，我还有一个选择，根据该选择(医生名)获取日历的事件，单击时有一个按钮，对话框将出现(另一个组件)对话框中，我有一个在选择后添加事件的表单，当我发布API时，我将其保存在本地存储中，但是刷新页面并重新选择医生姓名后，添加的事件不会出现在我的日历上. 但是我想，当我单击保存"按钮时，将其直接添加到日历上，并出现在日历上.
I have a react-big-calendar (The parent container), I have also a select which, the events of the calendar are fetched according to this select ( doctor name ) and I have a button when I click on it, the dialog will be appears (another component), on this dialog, I have a form to add an event after the select, when I post my API, I save it on local storage, but the event added doesn't appears on my calendar just after refresh the page and reselect the doctor name. But I want, when I click on the save button, will be added directly on the calendar and it will be appeared on the calendar.
我的日历代码是:
import Popup from './Popup';
export default class Calendar extends Component {
constructor(props){
super(props);
this.state = {
events : [],
open: false,
}}
componentDidMount = () => {
fetch(process.env.REACT_APP_API_BACKEND_YET+'get_liste_praticien.php')
.then(Response => Response.json())
.then(data => {
this.setState ({ praticiens : data })
localStorage.setItem('Liste de praticiens ', JSON.stringify(this.state.praticiens))
})
}
fetchData = (nom,identifiant_user) => {
this.setState({
events: [],
evtStorage:[],
prevEvents:[],
evtBackend:[]
})
fetch(process.env.REACT_APP_API_BACKEND+'get_liste_planning')
.then(Response => Response.json())
.then(data => {
let evts = data.ListeResult;
for (let i = 0; i < evts.length; i++) {
evts[i].start = moment(evts[i].start).toDate();
evts[i].end = moment(evts[i].end).toDate();
if(evts[i].typeplanning === '0') this.setState({isConges:true})
this.state.events.push(evts[i])
}
this.setState({
evtBackend: evts,
events: evts
})
localStorage.setItem("Liste de planning de " + nom, JSON.stringify(this.state.events));
})
const evtCached1 = JSON.parse(localStorage.getItem('Liste récente de planning de ' + nom));
if(evtCached1 !== null) {
for (let j = 0; j < evtCached1.length; j++) {
evtCached1[j].start = moment(evtCached1[j].start).toDate();
evtCached1[j].end = moment(evtCached1[j].end).toDate();
if(evtCached1[j].typeplanning === '0') this.setState({isConges:true})
this.state.events.push(evtCached1[j]);
}
this.setState({
events:this.state.events,
});
localStorage.removeItem("Liste de planning de " + nom);
}}
// For the select
handlePraticienChange = id_user => {
this.setState({
openPopupAjout: true,
id_user: id_user
},() => {
this.state.praticiens.map((praticien)=> {
if(this.state.id_user === praticien.id_user){
this.setState ({ nom_user: praticien.nom_user})
this.fetchData(praticien.nom_user, praticien.identifiant_user);
}
})
}
);
}
// for the popup
ModalAjoutb = (ref) => {
if (ref) {
this.ajoutb = ref.handleAjouterb;
} else {
this.ajoutb = null;
}
}
render() {
return (
<div>
<button className="bp3-button bp3-icon-add-to-artifact .bp3-fill" tabIndex="0" onClick={() => this.ajoutb(this.state.id_user, this.state.events)}>Add event</button>
<Select onChange={this.handlePraticienChange} value={this.state.id_user}>
{this.state.praticiens.map((praticien) =>
<Option key={praticien.id_user} value={praticien.id_user}>{praticien.nom_user}</Option>
)}
</Select>
<DragAndDropCalendar

我想刷新我的事件列表，并在弹出窗口中的张贴表单上而不是在刷新页面后出现在日历上添加我的事件，我将重新选择医生.
I want to refresh the list of my events and appear my event added on the calendar afer post form on the popup and not after the refresh of the page and I will reselect the doctor.
我该如何解决?
推荐答案
不要在弹出窗口中以您的状态保存事件.直接从道具访问事件.
Don't save events in your state in Popup access the events directly from props.
在您的日历中，创建一个将更新状态的函数.
In your Calendar, create a function that'll update the state.
updateEvents = (events, callback = () => {}) => {
this.setState(
{
events
},
callback
);
};
<Popup updateEvents={this.updateEvents} ref={this.ModalAjoutb} id_user={this.state.id_user} events={this.state.events} />
弹出

constructor(props) {
super(props);

handleAjouterb = id_user => {
this.setState(

openPopupAjout: true,
