为什么我的 reactstrap Collapse 不反映我的初始或更改状态

Question

我正在尝试使用 reactstrap 的 Collapse 折叠两个交替的部分。

import React, { Component, Fragment, Suspense } from "react";
import ReactDOM from 'react-dom';
import { PDFViewer } from '@react-pdf/renderer'
import NewWindow from 'react-new-window'
import Config from 'config';
import { Button, Collapse } from 'reactstrap';
import { formatter } from '../common.js'
import { format } from 'date-fns';
import Pagination from '../Pagination';
import "./Order.css";
import Modal from 'react-modal';
import PaymentModal from './paymentModal.js';
import Invoice from './Reports/Invoice';

Modal.setAppElement('#root');

let PageSize = 25;

class Portal extends React.Component {
    constructor() {
        super();
        this.state = {
            name: 'React',
            apiData: [],
            currentPage: 1,
            currentTableData: [],
            orderList: [],
            isOpen: false,
            pdfView: null,
            viewInvoices: true,
            viewOrders: false
        };
    }

    showInvoices() {
        console.log("Show Invoices Clicked")
        this.setState({ viewInvoices: true });
        this.setState({ viewOrders: false });
    }

    showOrders() {
        console.log("Show Orders Clicked")
        this.setState({ viewInvoices: false });
        this.setState({ viewOrders: true });
    }

    async componentDidMount() {        
        console.log('app mounted');

        const tokenString = sessionStorage.getItem("token");
        const token = JSON.parse(tokenString);

        let headers = new Headers({
            "Accept": "application/json",
            "Content-Type": "application/json",
            'Authorization': 'Bearer ' + token.token
        });
        
        const response = await fetch(Config.apiUrl + `/api/Orders/GetAllInvoices`, {
            method: "GET",
            headers: headers
        });
        const json = await response.json();
        console.log(json);
        this.setState({ orderList: json });
    }

    componentDidUpdate(_, prevState) {
        console.log('Component Updated');
        if (prevState.currentPage !== this.state.currentPage || prevState.orderList !== this.state.orderList) {
            const firstPageIndex = (this.state.currentPage - 1) * PageSize;
            const lastPageIndex = firstPageIndex + PageSize;
            this.setState({ currentTableData: this.state.orderList.slice(firstPageIndex, lastPageIndex) });
        }
    }
    
    render() {
        const orders = this.state.orderList;
        const currentTableData = this.state.currentTableData;
        const { isOpen } = this.state;
           

        let onRequestClose = () => {
            this.setState({ isOpen: false });
        }

        let handleClick = () => {
            console.log("Clicked")
            this.setState({ isOpen: true });
        }        

        function handleInvoiceClick(e, invoice) {            
            e.preventDefault();
            console.log(`invoice: ${JSON.stringify(invoice)}`)
            if (this.state.pdfView === null) {
                const headerString = sessionStorage.getItem("header");
                const header = JSON.parse(headerString);
                const buff = new Buffer(header.logoImage, 'base64');                
                let pdf = (       
                    <PDFViewer width="1000" height="600" className="portal">

                );
                this.setState({ pdfView: pdf });
            } else {
                this.setState({ pdfView: null });
            }
        }

        handleInvoiceClick = handleInvoiceClick.bind(this);

        return (

                                />
                        </Collapse>
                        <Collapse isOpen={this.state.showOrders}>
                            <h3>Open Orders</h3>
                            <h4>A list of completed orders purchased under this account.</h4>
                        </Collapse>
                    </div>
                </div>
            </div>
        );
    }
}
export default Portal;

isOpen 似乎没有在读我的 state。 Portal 两个部分都已折叠的负载。我的两个按钮运行（我得到了两个的控制台日志条目）但不影响显示。我认为初始 Invoice 也应该打开。为什么我的 reactstrap Collapse 元素不反映我的初始状态或更改后的状态？我需要向 componentDidUpdate 添加任何内容吗？任何提示或建议将不胜感激。

reactstrap = reactstrap@9.0.1

我认为你使用了错误的变量

<Collapse isOpen={this.state.showInvoices}>
<Collapse isOpen={this.state.showOrders}>

应该是

<Collapse isOpen={this.state.viewInvoices}>
<Collapse isOpen={this.state.viewOrders}>

show..个是函数。 isOpen 需要一个布尔值
