Question

我正在从主要组件渲染此组件。我在react-bootstrap中遇到了Modal的问题。我的模态没有正确显示。我附上了我的模态看起来的截图。请问有人可以提供帮助吗？

这就是我的模型出现的方式 https://i.stack.imgur.com/wvnmU.png

import React, { Component } from 'react';
import Button from 'react-bootstrap/lib/Button';
import Modal from 'react-bootstrap/lib/Modal';

class Add_Recipe extends Component {
    constructor(){
        super();
        this.state={
            showAdd: false
        };
    }
  handleAddRecipe(e){
      this.setState({showAdd: true});
  }

close() {
    this.setState({ showAdd: false });
  }

render() { 

      return(
          <div className="Add_Recipe">

            <Button onClick ={this.handleAddRecipe.bind(this)} bsStyle="primary" bsSize="large"> Add Recipe </Button>
                <Modal show={this.state.showAdd} onHide={this.close}>
          <Modal.Header closeButton>
            <Modal.Title id="modalTitle">Add a Recipe</Modal.Title>
          </Modal.Header>
          <Modal.Body>
            <p>
             Hello i am Modal..!!
            </p>
          </Modal.Body>
          <Modal.Footer>
            <p>
               Hello I am Footer
            </p>
          </Modal.Footer>
        </Modal>
          </div>
      );
}

}
export default Add_Recipe;

      Notice the use of %PUBLIC_URL% in the tags above.
      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.

      Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

这是我的index.js文件

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import Bootstrap from 'bootstrap/dist/css/bootstrap.css';

ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();

模态没有出现在React.js中
