React Date Picker Onchange方法令人困惑

Question

我正在使用react-date-picker，我想将其创建为日期选择器组件，可以在页面的每个部分使用。 我遇到的问题是onchange方法，因为在状态更改时，它不知道要更改的列。 我在onchange方法中丢失了一些东西。 当我选择一个日期时，错误是

无法读取未定义值的属性

export interface IIDateTimePropextends extends IFormControlProps {
//options from react-datepicker
    type?: string;
    dateFormat?:string;
    // optional properties

    peekNextMonth?:boolean;
    showMonthDropdown?:boolean;
    showYearDropdown?:boolean;
    dropdownMode?:string;
    placeholderText?:string;
    selected?:string;
    onKeyPress?: (e: any) => {};
    onKeyUp?: (e: any) => {};
    step?: number;
    checked?:boolean;

export class DatePickerNew extends React.PureComponent<IIDateTimePropextends, any>{
    classes: string[];

    constructor(props: IInputProp) {
        super(props);
        this.state = {
            dirty: false,
            valid: false,

        const onChange = this.props.onChange || ((a: any) => { });

        const result = e.target.value 
        e.target.value = DateTime.parse(e.target.value, DateTime.dbDateOutPutFormat);

        onChange(e);

        this.setState({

        onBlur(e);

        onChange(e);


        if (this.state.dirty) {
            this.setState((prevState: any) => ({
                dirty: prevState.dirty,

        this.classes = this.props.classes || [];

        return (
            <ErrorBoundary errorMessage="Error rendering DatePicker">

                  <DatePick

                    showYearDropdown
                    dropdownMode="select"
                    type="text"
                    placeholderText="DD/MM/YYYY"
                    />


            </ErrorBoundary>);
    }
}

当我调用另一个称为DaysSetup的组件时

<DatePickerNew 
id="holidayDate" 
title="Holiday Date" 
label="Holiday Date"
required={true} 
 name="holidayDate"
onChange=???//don't know what to do here
selected={this.state.model.holidayDate}
/>
