Question

使用Reactjs和Bootstraps一次显示一个折叠内容。

下面的代码使用jquery和bootstrap4来显示和隐藏一次单击每个按钮时的折叠内容并且工作正常。

<!doctype html>
<html>
    <head>

  <meta charset="utf-8">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.6/umd/popper.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>
<script>
$( document ).ready(function() {

  $('.collapse').on('show.bs.collapse', function () {

    // hide all accordion except the clicked one
    $('.collapse').not(this).collapse('hide');

  });

});

</script>



    </head>
    <body>


  <a href="#content1"  data-toggle="collapse">Content1..</a>
  <a href="#content2"  data-toggle="collapse">Content2</a>
  <a href="#content3"  data-toggle="collapse">Content3</a>
 <br>





 <div id="content1" class="collapse ">
<h1>Content 1 records</h1>

<a href="#content1" class="btn btn-default" data-toggle="collapse">Close </a>

  </div>


 <div id="content2" class="collapse ">
<h1>Content 2 records</h1>

<a href="#content2" class="btn btn-default" data-toggle="collapse">Close</a>

  </div>

 <div id="content3" class="collapse ">
<h1>Content 3 records</h1>

<a href="#content3" class="btn btn-default" data-toggle="collapse">Close</a>

  </div>



</body></html>

现在我必须在reactjs中获得其等效项。我已经安装了Bootstrap并且Reactjs代码每次都显示折叠内容该按钮是单击。

这是我的Reactjs问题。我希望它像上面的jquery代码一样仅显示为一个折叠内容。请如何将这个jquery代码转换为reactjs等效项，或者还有其他选择

$( document ).ready(function() {

  $('.collapse').on('show.bs.collapse', function () {

    // hide all accordion except the clicked one
    $('.collapse').not(this).collapse('hide');

  });

});

这是Reactjs代码

import React, { Component, Fragment } from "react";
import { render } from "react-dom";
import $ from 'jquery';



class Collapse extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
    };
  }





    render() {

      return (
        <span>
          <label>
            <ul>



  <a href="#content1"  data-toggle="collapse">Content1..</a>
  <a href="#content2"  data-toggle="collapse">Content2</a>
  <a href="#content3"  data-toggle="collapse">Content3</a>
 <br />


 <div id="content1" class="collapse ">
<h1>Content 1 records</h1>

<a href="#content1" class="btn btn-default" data-toggle="collapse">Close </a>

  </div>


 <div id="content2" class="collapse ">
<h1>Content 2 records</h1>

<a href="#content2" class="btn btn-default" data-toggle="collapse">Close</a>

  </div>

 <div id="content3" class="collapse ">
<h1>Content 3 records</h1>

<a href="#content3" class="btn btn-default" data-toggle="collapse">Close</a>

  </div>



          </ul>
        </label>
      </span>
    );
  }
}

下面是一个示例代码，显示了如何执行此操作：

class App extends React.Component {
  constructor(props) {
    super(props);
    this.toggleAccordion = this.toggleAccordion.bind(this);
    this.state = {
      accordion: [true, false, false],
    };
}

  toggleAccordion(tab) {

    const prevState = this.state.accordion;
    const state = prevState.map((x, index) => tab === index ? !x : false);

    this.setState({
      accordion: state,
    });
  }

  render() {
    return (
      <div className='wrapper'>
