Close Modal Popup using Esc key on keyboard

Question

I need to close the modal also using the "ESC" key, at the moment it is closing the "CLOSE" and "CONFIRM" button. i'm using reactstrap, react hooks. keyboard {show} and handleClose it didn't work.

Here is the code:

const DeleteUserModal = props => {
    const { user, show } = props;

    const deleteUser = async () => {
        await props.removeUser(user);
        props.onCloseModal();
    };

    const handleKeyPress = target => {
        if (target.charCode === ENTER_KEY) {
            deleteUser();
        }
    };
    


    return (
        <div onKeyPress={handleKeyPress}>
            <Modal isOpen={show} toggle={props.onCloseModal}  >
                
                <ModalHeader toggle={props.onCloseModal}>
                    <IntlMessages id="modal.delete.user.title" />
                </ModalHeader>

                <ModalBody>
                    <IntlMessages id="modal.delete.user.description" />
                </ModalBody>

                <ModalFooter>
                    <Button className="cancel" onClick={props.onCloseModal}>
                        <IntlMessages id="modal.common.cancel" />
                    </Button>
                    <Button className="action" onClick={deleteUser}>
                        <IntlMessages id="modal.common.ok" />
                    </Button>
                </ModalFooter>
            </Modal>
        </div>
    );
};

export default DeleteUserModal;

follows the modal with two actions

Answer 1

In vanilla JavaScript, you could do:

document.onkeydown = function (evt) {
    if (evt.keyCode == 27) {
        // Escape key pressed
        props.onCloseModal();
    }
};

Answer 2

Here's an example using TypeScript and the new event.key property:

 React.useEffect(() => {
    const closeOnEscapePressed = (e: KeyboardEvent) => {
      if (e.key === "Escape") {
        props.onCloseModal();
      }
    };
    window.addEventListener("keydown", closeOnEscapePressed);
    return () =>
      window.removeEventListener("keydown", closeOnEscapePressed);
  }, []);

Answer 3

You can check bootstrap documentation.

If nothing found, then you could add an event listener to the ESC key press and than call onCloseModal

Answer 4

You can setup an event listener.

 useEffect(() => {
      const close = (e) => {
        if(e.keyCode === 27){
          props.onCloseModal()
        }
      }
      window.addEventListener('keydown', close)
    return () => window.removeEventListener('keydown', close)
  },[])
