javascript - 如何在 react 组件中打开引导模式？

Question

有一个 react 组件。需要在页面加载时打开引导模式。尝试使用 jQuery 和简单的 JavaScript，但没有成功。

react 组件:

import React, { Component } from 'react'
import $ from 'jquery'

class Login extends Component {
  componentDidMount() {
    // here I want to open modal
  }

  render() {
    return (
      <div className="modal fade WelcomeModal" id="WelcomeModal" tabIndex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
        <div className="modal-dialog modal-dialog-centered" role="document">
          <div className="modal-content">
            <div className="modal-header">
              <div className="camera-box">
                <img alt="" src="/img/yellow-logo.svg"/>
                <h5 className="modal-title" id="exampleModalLabel">Welcome to the Cozy App!</h5>
              </div>                             
            </div>
            <div className="modal-body">
              <p className="text-center">On the following screens weʼll ask you to register the Cozys in your home & adjust your temperature settings. Youʼll need the following information:</p>
            </div>
          </div>
        </div>
      </div>
    )
  }
}

看看这个 codepen它展示了如何在不需要 jQuery 的情况下将 Bootstrap 类与 React 结合起来

toggleModal = () => this.setState({
              showLogin: !this.state.showLogin
          })
