React-Bootstrap Multiple Modal

问题

I am using React-bootstrap in my project. I need to open multiple dialog. Is there any way to achieve this?

Note: There is answers for bootstrap here but it does not work in react-bootstrap. Thanks.

we just handled multiple modals by having each pass in a different id and then setting the 'show' state to that:

https://github.com/AgileVentures/agile-ventures-website-react-front-end/blob/4_homepage_changes_mob/src/App.js#L26

class App extends Component {

  constructor(props, context) {
    super(props, context);

    this.handleShow = this.handleShow.bind(this);
    this.handleClose = this.handleClose.bind(this);

    this.state = {
      show: null
    };
  }

  handleClose() {
    this.setState({show: id});
  }

  handleShow(id) {
    this.setState({show: id});
  }

  render() {
    return (
      <div className="App">

        <Grid>
          <Row>
            <Col xsOffset={1} sm={5}>
              <Button bsStyle="primary" bsSize="large" onClick={() => this.handleShow('here')}>
                <h1>You are here!</h1>
              </Button>
              <Modal
                show={this.state.show == 'here'} onHide={this.handleClose}
              >
                <Modal.Header closeButton closeLabel="close window">
                </Modal.Header>
                <Modal.Body>
                  <p className='landing-page-markers you-are-here'>Tired of toy projects, tutorials and online courses?
                      <img src={logo} className="App-logo" alt="logo" />
                  </p>
                </Modal.Body>
              </Modal>
            </Col>
          </Row>
          ... more modals passing in different ids ...

i used multiple models like this

render() {
    return(
       <div>
           <button onClick={() => this.setState({ showModal1:true, showModal2:false});} >open modal one</button>

          <button onClick={() => this.setState({ showModal2:true, showModal1:false});} >open modal two</button>

          <Modal show={this.state.showModal1} onHide={() => this.setState({ showModal1:false});}>
           modal one content..
          </Modal>

          <Modal show={this.state.showModal2} onHide={() => this.setState({ showModal2:false});}>
          modal two content..
       </Modal>

     </div>
   );
}

It depends on what do you want to achieve. I have multiple react bootstrap modal dialogs and also have embedded dialogs, like modal dialog shows popup with error message. Generally you can define state variable, like this:

this.state = {showModal1:true, showModal2:false,...}

In your render function you can do like this:

render() {
    return(
       <div>
           <Modal show={this.state.showModal1}>
              some modal 1 text comes here
           </Modal>
           <Modal show={this.state.showModal2}>
              some modal 2 text comes here
           </Modal>
       </div>
     );
}

In the code above, if both showModal1 and showModal2 are true, you will get both modal dialogs and the second will above the first one.

If you are using React 16.8+, you can use the React Hook useState (and functional component) so you can specify which modals you want it to appear based on the state:

export const MyModals = () => {
const [modalState, setModalState] = useState< "modal-one" | "modal-two" | "close" >("close")

const handleShowModalOne = () => {
 setModalState("modal-one")
}

const handleShowModalTwo = () => {
 setModalState("modal-two")
}

const handleClose = () => {
 setModalState("close")
}

return (
 <div>
   <Button onClick={handleShowModalOne}>Show Modal One</Button>

   <Modal show={modalState === "modal-one"}>
     <Modal.Body>This is Modal One</Modal.Body>
     <Modal.Footer>
       <Button onClick={handleShowModalTwo}>Show Modal Two</Button>
     </Modal.Footer>
   </Modal>

   <Modal show={modalState === "modal-two"}>
     <Modal.Body>This is Modal Two</Modal.Body>
     <Modal.Footer>
       <Button onClick={handleClose}>Close</Button>
     </Modal.Footer>
   </Modal>
 </div>
)
}
