Question

Reactstrap在文档中没有 Accordion 的正式示例。

使用卡组件，您可以扩展默认的折叠行为以创建手风琴。要正确实现手风琴样式，请确保使用.accordion作为包装器。

<div class="accordion" id="accordionExample">
  <div class="card">
    <div class="card-header" id="headingOne">
      <h2 class="mb-0">
        <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </button>
      </h2>
    </div>

    <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
      <div class="card-body">

是否有像Bootstrap 4文档示例这样的Accordion组件？

Answer 1

Reactstrap docs是正确的。您可以使用Card和Collapse组件创建一个手风琴。首先，初始化您的构造函数和状态。

    constructor(props) {
      super(props);
      this.toggle = this.toggle.bind(this);
      this.state = { collapse: 0, cards: [1, 2, 3, 4, 5] };
    }

然后是切换/折叠手风琴的方法。

    toggle(e) {
      let event = e.target.dataset.event;
      this.setState({ collapse: this.state.collapse === Number(event) ? 0 : Number(event) });
    }

还有render()函数：

render() {
  const {cards, collapse} = this.state;
  return (
    <div className="container">
        <h3 className="page-header">Reactstrap Accordion using card component</h3>
        {cards.map(index => {
          return (
            <Card style={{ marginBottom: '1rem' }} key={index}>
              <CardHeader onClick={this.toggle} data-event={index}>Header</CardHeader>
              <Collapse isOpen={collapse === index}>
              <CardBody>Example</CardBody>
              </Collapse>
            </Card>
          )
        })}     

      </div>
  );
}

别忘了导入：

import { Collapse, CardBody, Card, CardHeader } from 'reactstrap';

如果您使用reactstrap和react Hooks，则可以按以下步骤操作

1从reactstrap导入所需的组件

import { Collapse, CardBody, Card, CardHeader} from 'reactstrap';

2-从react导入useState

import React, {useState} from 'react';

3-在组件内创建状态

const [toggleQuestion, setToggequestion] = useState(1);//1 is the default id to be opened by default

4-创建您的手风琴。注意：在我的情况下，我仅切换身体，但您可以通过移动折叠来切换所有内容。

<Card>
    <CardHeader onClick={() => setToggequestion(1)}>
        <span className="font-weight-bold">title</span>
    </CardHeader>
    <Collapse  isOpen={toggleQuestion === 1 ? true : false}>
        <CardBody>
            example text
        </CardBody>
    </Collapse>
</Card>

<Card>
    <CardHeader onClick={() => setToggequestion(2)}>
        <span className="font-weight-bold">title 2</span>
    </CardHeader>
    <Collapse  isOpen={toggleQuestion === 2 ? true : false}>
        <CardBody>
            example text 2
        </CardBody>
    </Collapse>
</Card>

现在，您可以创建任意数量的内容，而只需更改ID。在我的情况下，ID仅为1和2
