i am not able to update modal state based on received props value from other component in reactjs. i have tried all things but not working. please suggest on it it will be appreciable.

const ModalExample = ({ elem }) => {

const [modal, setModal] = useState(elem);
useEffect(() => {
    console.log('elem', elem);
})

const toggle = () => {
    setModal(false);
}


return (
    <div>
        <Modal isOpen={modal} toggle={toggle}>
            <ModalHeader toggle={toggle}>Modal title</ModalHeader>
            <ModalBody>
                Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

            </ModalBody>
            <ModalFooter>
                <Button color="primary" onClick={toggle}>Do Something</Button>{' '}
                <Button color="secondary" onClick={toggle}>Cancel</Button>
            </ModalFooter>
        </Modal>
    </div>
);

}

CodePudding user response：

Instead of passing elem prop directly inside useState

do something like this.

const [modal, setModal] = useState(false)

useEffect(() => {
  setModal(Boolean(elem)) // I suppose it is not boolean so make it boolean
},[elem])
