I have a Modelmenu that is nested in the parent component, it implements the function of opening a modal window by click. Also in this parent component there is a child component to which you need to bind the function of opening a modal window by one more element. I can do this if all the logic is in the parent component, but this is a bad practice, since I will have to duplicate the code on each page in this way. How can I do this? I'm sorry, I'm quite new, I can't understand the callback.
Parent:
const Home: NextPage = () => {
const handleCallback = (handleOpen: any) => {
}
return (
<>
<ModalMenu parentCallback={handleCallback}/>
<Slider handleCallback={handleCallback}/>
</>
)
}
Modal:
export const ModalMenu: FC = (props) => {
const [play, setPlay] = useState<boolean>(false)
const handleOpen = () => {
props.parentCallback(setPlay(!play))
};
const handleClose = () => {
setPlay(false)
setPlay(!play)
};
return
}
Child:
export const Slider: FC= (props) => {
return (
<>
<Image nClick={props.handleCallback}/>
</>
If you're looking to pass down values and/or functions from a parent to two or more children, I think it's better to just have the values and functions in the parent
Parent :
const Home: NextPage = () => {
const [play, setPlay] = useState<boolean>(false)
const handleOpen = () => {
setPlay(prev => !prev)
};
const handleClose = () => {
setPlay(false)
setPlay(!play)
};
return (
<>
<ModalMenu handleOpen={handleOpen} handleClose={handleClose} play={play}/>
<MainSlider <ModalMenu handleOpen={handleOpen} handleClose={handleClose} play={play}/>
</>
)
}
if you want to pass an interface to the props in the children for typescript your interface will look something like this
interface iProps {
play : boolean;
handleOpen : () => void;
handleClose : () => void;
}
export const ModalMenu: FC = (props):iProps => {
// you can easily access all you want
const {handleClose, handleOpen, play} = props
return
}
export const Slider: FC= (props): iProps => {
const {handleClose, handleOpen, play} = props
return (
<>
<Image onClick={handleOpen}/>
</>
