如何使用 Reactstrap 制作 Accordion 组件？

Question

Reactstrap 在文档中没有 Accordion 的官方样本。

Using the card component, you can extend the default collapse behavior to create an accordion. To properly achieve the accordion style, be sure to use .accordion as a wrapper.

<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">

      </div>
    </div>
  </div>
  <div class="card">
    <div class="card-header" id="headingTwo">
      <h2 class="mb-0">
        <button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
          Collapsible Group Item #2
        </button>
      </h2>
    </div>
    <div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample">
      <div class="card-body">

    <div class="card-header" id="headingThree">
      <h2 class="mb-0">
        <button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
          Collapsible Group Item #3
        </button>
      </h2>
    </div>
    <div id="collapseThree" class="collapse" aria-labelledby="headingThree" data-parent="#accordionExample">
      <div class="card-body">

是否可以使用 Accordion 组件，例如 Bootstrap 4 文档示例？

Answer 1

Reactstrap docs 是对的。您可以使用 Card 和 Collapse 组件创建手风琴。首先，初始化你的构造函数和状态。

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

然后你的方法 toggle/collapse 手风琴。

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

和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';

Source Code

Answer 2

如果你使用reactstrap和react Hooks你可以按如下方式做

1 从 reactstrap 中导入所需的组件

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

2- 从反应中导入 useState

import React, {useState} from 'react';

3- 在您的组件中创建您的状态

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

4- 创建手风琴。注意：在我的例子中，我只切换主体，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>

现在你想创建多少就创建多少，只需要更改ID即可。在我的例子中，id 只是 1 和 2
