I have my modal component in a different file and I'm trying to open it from another component

Question

BuySectionItem.js

    class BuySectionItem extends React.PureComponent {
        constructor( props ) {
            super( props );

            this.state = {
                modalIsOpen:        false,
            }
            this.toggleTicketModal = this.toggleTicketModal.bind( this );
        }

        toggleTicketModal = () => {
            this.setState( { modalIsOpen: ! this.state.modalIsOpen } );
        }

        componentDidMount() {
            // this.setActivePrice();
        }

        outputBuyButton( offer ) {
            // Universe ID override is present.

                return  <Button text="Buy Ticket" type="green-gradient" onClick={ this.toggleTicketModal }/>

            return null;
        }

        render() {
            <div>
                {this.state.modalIsOpen &&
                    <TicketModal isOpen={this.state.modalIsOpen} toggleTicketModal={ this.toggleTicketModal } />
                }
            </div>;
        }
    }

    export default BuySectionItem;

TicketModal.js

    import React from 'react';
    import Modal from 'react-modal';
    import PropTypes from 'prop-types';

    const customStyles = {
        content: {
            top:         '50%',
            left:        '50%',
            right:       'auto',
            bottom:      'auto',
            marginRight: '-50%',
            transform:   'translate(-50%, -50%)',
        },
    };

    Modal.setAppElement( 'body' )

    class TicketModal extends React.Component {

componentDidMount() {
        this.handleKeyEvents();
    }

    componentWillUnmount() {
        this.removeKeyHandler();
    }

    /**
     * Watch for the escape key when the modal is open to allow users to escape from the modal.
     */
    handleKeyEvents() {
        const handleKeyDown = event => {
            if ( event.keyCode === 27 ) {
                this.props.toggleTicketModal( event );
            }
        };

        /*

                toggleTicketModal,
            } = this.props;
            return (

                <h2>ID of this modal is 100</h2>
                <h3>This is an awesome modal.</h3>
                <button onClick={toggleTicketModal()}>close</button>
              </div>
            </div>
          </Modal>
            )
        }
    }
    TicketModal.propTypes = {
        pending:           PropTypes.bool,

    export default TicketModal;


As you can see I am trying to open the ticket modal component from the `buysectionitem` component on a button Click.

But for some reason the Modal doesn't seem to be opening.

When I kept a break point I see that the `togglemodal` function is being called but doesn't open at all.

I added some more code as I need guidance with the handle key events as well. This key event which was supposed to remove the modal from the screen when I click escape which doesn't seem to be working.

Answer 1

you are calling the toggleTicketModal function when the TicketModal renders,call it like this

<button onClick={()=>toggleTicketModal()}>close</button>

this will do.
