I have a component which i have imported into another component. When I click the component, the onclick function refuses to run.
This is the code for the component
const HomeFeedCard = ({ name, image, published, quantity, weight }) => {
const classes = useHomeFeedCardStyles()
return (
<Grid item xs={6} md={3} sm={4} lg={3}>
<Paper elevation={5}>
<img src={image?.url} alt='Product' className={classes.image} />
<div className={classes.container}>
<Avatar
alt='image'
src='https//user.png'
sx={{ width: 56, height: 56, mr: 1 }}
/>
<div className={classes.textContainer}>
<Typography variant='h6' component='body'>
<LinesEllipsis text={` ${name}`} />
</Typography>
<Typography>{`${quantity} left | ${weight}KG`}</Typography>
</div>
</div>
</Paper>
</Grid>
)
}
THIS IS THE function that runs the onClick function. The console returns nothing
<HomeFeedCard
key={product._id}
name={product.productName}
published={product.published}
image={product.images[0]}
quantity={product.quantity}
weight={product.weight}
onClick={() => console.log('product', product.productName)}
/>
Your onClick is not defined in your function HomeFeedCard.
const HomeFeedCard = ({ name, image, published, quantity, weight, onClick }) => {
return (
<div onClick={onClick} />
)
}
If you don't know which properties you want to set use: https://reactjs.org/docs/jsx-in-depth.html#spread-attributes
In the HomeFeedCard, you are not expecting an onClick function as a prop.
You need to explicitly bind the onClick to an actual element. You can wrap content inside HomeFeedCardwith adiv`.
OR, pass onClick further to Grid if accepts a click handler.
const HomeFeedCard = ({
name,
image,
published,
quantity,
weight,
onClick
}) => {
const classes = useHomeFeedCardStyles();
return (
<div onClick={onClick}>
<Grid item xs={6} md={3} sm={4} lg={3}>
<Paper elevation={5}>
<img src={image?.url} alt="Product" className={classes.image} />
<div className={classes.container}>
<Avatar
alt="image"
src="https//user.png"
sx={{ width: 56, height: 56, mr: 1 }}
/>
<div className={classes.textContainer}>
<Typography variant="h6" component="body">
<LinesEllipsis text={` ${name}`} />
</Typography>
<Typography>{`${quantity} left | ${weight}KG`}</Typography>
</div>
</div>
</Paper>
</Grid>
</div>
);
};
<HomeFeedCard
key={product._id}
name={product.productName}
published={product.published}
image={product.images[0]}
quantity={product.quantity}
weight={product.weight}
onClick={() => console.log("product", product.productName)}
/>

i have a Modal:
with certain fields, if i open the dropdown and select one of the fields, it does change the state of the Object but doesnt render it in the UI (i reopen the dropdown with the selections so you can see whats behind):
the weird thing about it is, if i do it outside of the Modal, it does work, so it has anything todo with my Modal component?
Here is the BaseModal component:
declare interface IBaseModal {
readonly sx: BaseModalStyle;
readonly body?: React.ReactNode;
readonly isOpen: boolean;
readonly toggleModal: any;
}
const BaseModal: FC<IBaseModal> = ({sx, body, isOpen, toggleModal}: IBaseModal) => (
<Modal open={isOpen} onClose={toggleModal}>
<BaseModalView width={sx.width} height={sx.height}>
{body}
</BaseModalView>
</Modal>
)
then i use it as follows in the view component:
<BaseModal
sx={{width: 800, height: 600}}
isOpen={isModalOpen}
toggleModal={() => setModalOpen(isModalOpen)}
body={modalBody}
/>
const localizer = momentLocalizer(moment);
const [events, setEvents] = useState<CalendarEvent[]>([])
const [schedule, setSchedule] = useState<ISchedule>(initialScheduleEvent);
const [isModalOpen, setModalOpen] = useState<boolean>(false);
const [modalBody, setModalBody] = useState<React.ReactNode | undefined>();
const handleSelectDate = (e: SlotInfo) => {
setModalBody(<Grid container>
<Grid item xs={6}>
<Grid container direction="row" sx={{padding: 2}}>

))}

}}))
}}

setModalOpen(true);
}
It also rerenders after i select a certain value in the dropdown for example. but the Modal does not update its value, and i dont get why... i hope for any help.
Small Edit:
After selecting a value and closing / reopening the Modal, the value does change, but why not straight after selecting it but after reopening it?
I fixed the issue having the Body of the Modal, not in a variable but straight in the return body of the component
I have three components im trying to connect together to add the number of items I have in a shopping cart. I have the main component which creates the CartCount object and setCartCount functionality:
function MinerStore() {
const [cartCount, setCartCount] = useState([0]);
const addToCart = () => {
setCartCount(cartCount + 1);
};
return (
<>
<div >
<StoreNav cartCount={cartCount} />
<div>
<StoreCard addToCart={addToCart} />
</div>
</div>
</>
);
}
I also then have the two components I am trying to show the added count on as well as the added count functionality:
export default function StoreCard(addToCart) {
return (
<ThemeProvider theme={theme}>
<main>
<Container>
<Grid container spacing={3}>
{data.map((data) => (
<Grid item key={data.id} xs={12} sm={6} md={3}>
<Card>
<CardContent>
</CardContent>
<CardActions>
<div>
<Button onClick={addToCart}>
Add to Cart
</Button>
</div>
</CardActions>
</Card>
</Grid>
))}
</Grid>
</Container>
</main>
</ThemeProvider>
);
}
export default function StoreNav(cartCount) {
return (
<AppBar position="static">
<Toolbar>
<IconButton>
<Badge badgeContent={cartCount} color="primary">
<ShoppingCartIcon />
</Badge>
</IconButton>
</Toolbar>
</AppBar>
);
}
You've set your initial state as an array [0].
Set it as as 0 and check it out
And ofc as the people above mentioned you should either use props or {addToCart} in the child's parameter.
Then on button should look as such:
<Button onClick={addToCart /* or props.addToCart */}>Add to Cart </Button>
I'm triggering setClickedMovieId using onClick event. I also use useEffect to check if the value of state is set correctly, however, it consoles out the default value (zero).
I need to save the id of a clicked item in order to be able to use it at <NavLink to={"movie/" + clickedMovieId}>.
const MovieCards = () => {
const { movies } = useContext(MoviesContext);
const [clickedMovieId, setClickedMovieId] = useState<number>(0);
useEffect(() => {
console.log('Current value of movie id state', clickedMovieId);
}, [clickedMovieId]);
return (
<div >
<Grid container spacing={1}>
{movies.map((movie) => (
<Grid item xs={6} sm={2} key={movie.id}>
<NavLink to={"movie/" + clickedMovieId}>
<Card className="card">
<CardActionArea>
<CardMedia
component="img"
/>
</CardActionArea>
<CardActions>
<Button size="small" color="primary">
<FavoriteBorderIcon />
</Button>
<Button size="small" color="primary" onClick={() => setClickedMovieId(movie.id)}>
{movie.rating}
</Button>
</CardActions>
</Card>
</NavLink>
</Grid>
))}
</Grid>
</div>
);
}
export default MovieCards;
How can I fix it?
Thanks!
Solution:
<NavLink to={"movie/" + movie.id}>
i have a cards.js which has the following function. Now the calling method passes three values . header1, header2 and Link (this is the *.js page that has to be called)
export default function Cards(props) {
const classes = useStyles();
return (
<div className="App">
<Card className={classes.card} variant="outlined">
<CardContent>
<Typography
variant={"h5"}
gutterBottom
>
{props.header1}
</Typography>
<Typography
variant={"caption"} >
{props.header2}
</Typography>
<Divider className={classes.divider} light />
<Button variant="contained" color="secondary" onClick={()=> (call either link1.js or link2.js )}>
Lets goooooo!
</Button>
</CardContent>
</Card>
</div>
);
}```
calling method
class UIM extends Component {
render() {
return (
<div className="text-page">
<Grid container alignItems="center" justify="space-evenly" >
<Grid ><Cards header1="card 1 for a task1" header2="click text2" link="link1"/></Grid>
<Grid ><Cards header1=" card 2 for task 2" header2=" click text 2" link="link2"/></Grid>
</Grid>
</div>
)
}
}
I am new to react and learning right now, so wondering if such a thing is possible or should i use router to route to different pages (ie. call either link1.js or link2.js ) ??
I found out by by adding pathname:props.link i can get the button to link to multiple locations within the material ui button.
<Card className={classes.card} variant="outlined">
<CardContent>
<Typography
variant={"h5"}
gutterBottom
>
{props.header1}
</Typography>
<Typography
variant={"caption"} >
{props.header2}
</Typography>
<Divider className={classes.divider} light />
<Button variant="contained" color="secondary">
<NavLink to={{pathname:props.link}}>Lets goooooo!</NavLink>
</Button>
</CardContent>
</Card>
I have a search bar component that should take the value of the input, however I am using useState for my getters and setters and i am a bit confused as it is reported an error of
Below is my component, can you spot the erorr?
const SuppliersNavBar = (props) => {
const { classes } = props;
const [search, setSearch] = useState();
const updateSearch = (event) => {

console.log(event);
};
return (
<Fragment><Fab className={classes.addCircle} style={{ float: 'right',
marginRight: 10, marginBottom: 10, backgroundColor: '#3B70BC', color:

Events in React are handled through object pooling meaning that events aren't readable through the console. You can call event.persist() and you will be able to see it. Please look at this page for further information. https://reactjs.org/docs/events.html
