javascript - Ant Design 中的Rangepicker 的值如何获取？

Question

我有一个日期和时间的范围选择器表，该表是动态的，我可以添加和删除这些范围选择器，如下图所示:

我想将这些值存储在另一个表上以将其发送到后端，当我在范围选择器上有值时，我收到错误。

我的代码是:

import { DatePicker } from 'antd';
import moment from 'moment-timezone';
import fr_FR from 'antd/lib/locale-provider/fr_FR';
import "moment/locale/fr";
const { RangePicker } = DatePicker;
export default class App extends Component {
constructor(props) {
    super(props);
    this.state= {
        tranches :[{date:null}]
    }
  onChange(value, dateString) {
    console.log('Selected Time: ', value);
    console.log('Formatted Selected Time: ', dateString)
  }
  onOk(value) {
    console.log('onOk: ', value);
  }
  render() {
    return (
       <div>
         { 
                      this.state.tranches.map((el, i) => 
                        <Row key={i}>
                          <Col span={12}>
                            &nbsp; &nbsp; &nbsp;
                            <label className="pt-label .modifier"><strong>Période</strong></label>
                            <LocaleProvider locale={fr_FR}>
                              <RangePicker 
                                allowClear={false}
                                id="date" name= "date"
                                style={{ width: '547px', marginLeft:'20px'}} 
                                locale="fr" 
                                //placeholder={["Date de début","Date de fin"]} 
                                separator="-" 
                                onChange={this.onChange}
                                showTime={{ format: 'HH:mm' }}
                                format="DD/MM/YYYY HH:mm"
                                placeholder={['Date et heure de début', 'Date et heure de fin']}
                                onOk={this.onOk}
                              />
                            </LocaleProvider>
                          </Col>
                          <Col span={12}>
                            {i === 0 ? 
                                        <>                      
                                      <Icon type="plus-circle" theme="twoTone" twoToneColor="#52c41a"  onClick={this.ajouterTranche}/> 
                                          <br/> 
                                        </>
                                      :
                                        <>
                                       <Icon type="close-circle" theme="twoTone" twoToneColor="red"  onClick={this.supprimerTranche(i)}/>

                                          <Icon type="plus-circle" theme="twoTone" twoToneColor="#52c41a"  onClick={this.ajouterTranche}/>  
                                          <br/>
                                        </> 
                                      }
                          </Col>
</Row>
                    )}
}

我该如何修复它？

Answer 1

改变

onChange(value, dateString) {
 console.log('Selected Time: ', value);
 console.log('Formatted Selected Time: ', dateString)
}

至

onChange = (value, dateString) => {
 let date = this.state.date
 date.push(value)
 this.setState({date: date})
}
