I want to do row virtualization when scrolling (so that data is shown when scrolling)
But when scrolling, now the terrible glitches appear
Tell me what is the problem?
project - male-wind.surge.sh
A component with a table (react-window is used there):
import React, { Component } from "react";
import { connect } from "react-redux";
import actions from "../../actions";
import PropTypes from "prop-types";
import sort from "./sort";
import { FixedSizeList } from 'react-window';
function TitleColumn(data) {
return (
<Grid item xs={1}>
<Box className="title_elem">
<h3
className="table_title-text"
onClick={sort.bind(null, `${data.title.toLowerCase()}`, data.props)}
>
{data.title}
</h3>
{data.props.fourthData.data === `${data.title.toLowerCase()}` ? (
<p>{data.props.fifthData.data}</p>
) : null}
</Box>
</Grid>
);
}
class Table extends Component {
render() {
const data = this.props.info;
const Row = ({ index, style}) => {
return (
<Grid container className="table_row">
<Grid item xs={1}>
<Box className="table_elem name_elem">{data[index].name}</Box>

<Box className="table_elem date_elem">
{`${data[index].date.toLocaleString("en", {

</Box>
</Grid>
</Grid>
)
};
return (
<Grid

<Grid container className="table_title">
<TitleColumn props={this.props} title="Name" />

fifthData: PropTypes.object.isRequired
};
const mapStateToProps = store => {
return {
firstData: store.firstData,

setSortTitle: sortField => dispatch(actions.setSortTitle(sortField)),
changeArrow: arrow => dispatch(actions.changeArrow(arrow))
};
};
export default connect(mapStateToProps, mapDispatchToProps)(Table);
I try to use this solution, but it does not help - https://github.com/bvaughn/react-virtualized/issues/1327
you have to apply the style passed by list for list element rendering which sets height, width and top attributes. you can do as below
const Row = ({ index, style}) => {
return (
<Grid container className="table_row" style={style}>
<Grid item xs={1}>
<Box className="table_elem name_elem">{data[index].name}</Box>
</Grid>....…..

As you can see from the image on the left I have a map with the controls, on the right I have a series of fields (last update, a table and an input field).
What I would like to do is that when it reaches a certain size (device example) the right side goes down under the map, the map then takes all the available space.
As you can see from the image when you resize a part of the table you do not see, you have to scroll.
Can you give me a hand?

When I run the code below I expected that styles would be injected inside props, but I always end up getting undefined props.
I am not providing any props to this component.
const styles = theme => ({
root: {
'& .MuiTextField-root': {
margin: theme.spacing(1),
width: '25ch',
},
},
});
class Editor extends React.Component {
render() {
const { classes } = this.props;
return (
<div className="editor">
<form className={classes.root} noValidate autoComplete="off">
<TextField id="standard-basic" label="Standard" />
<Button variant="contained" color="primary">
Hello World
</Button>
</form>
</div>
);
}
}
export default withStyles(styles)(Editor);
Hi you can use makeStyles from '#material-ui/core/styles'. Please check complete example below:
import React from 'react';
import {makeStyles} from '#material-ui/core/styles';
import Grid from '#material-ui/core/Grid';
import FormLabel from '#material-ui/core/FormLabel';
import FormControlLabel from '#material-ui/core/FormControlLabel';
import RadioGroup from '#material-ui/core/RadioGroup';
import Radio from '#material-ui/core/Radio';
import Paper from '#material-ui/core/Paper';
const useStyles = makeStyles((theme) => ({
root: {
flexGrow: 1,
},
paper: {
height: 140,
width: 100,
},
control: {
padding: theme.spacing(2),
},
}));
export default function SpacingGrid() {
const [spacing, setSpacing] = React.useState(2);
const classes = useStyles();
const handleChange = (event) => {
setSpacing(Number(event.target.value));
};
return (
<Grid container className={classes.root} spacing={2}>
<Grid item xs={12}>
<Grid container justify="center" spacing={spacing}>
{[0, 1, 2].map((value) => (
<Grid key={value} item>
<Paper className={classes.paper}/>
</Grid>
))}
</Grid>
</Grid>
<Grid item xs={12}>
<Paper className={classes.control}>
<Grid container>
<Grid item>
<FormLabel>spacing</FormLabel>
<RadioGroup
name="spacing"
aria-label="spacing"
value={spacing.toString()}
onChange={handleChange}
row
>
{[0, 1, 2].map((value) => (
<FormControlLabel
key={value}
value={value.toString()}
control={<Radio/>}
label={value.toString()}
/>
))}
</RadioGroup>
</Grid>
</Grid>

I use a button from another component to access this Favorites component, but when I press the button, it doesn't load anything and the page goes blank. Now if I press the button twice, it shows me the information.
const Favorites = (props) => {
const [products, setProducts] = useState([]);
useEffect(() =>{
let productsArray = []
firebase.database().ref().child('favorites').orderByKey()
.once('value', snap => {
snap.forEach(child => {
if(child.val().user_id === firebase.auth().currentUser.uid){
firebase.database().ref('products/' + child.val().product_id)
.once('value')
.then(snapshot =>{
const favorite = {
id: snapshot.key,
name: snapshot.val().name,
category: snapshot.val().category,
description: snapshot.val().description,
image: snapshot.val().image,
price: snapshot.val().price,
stock: snapshot.val().stock,
};
productsArray.push(favorite);
});
}
});
setProducts(productsArray);
});
},[]);
return (
<Fragment>
<ul>
{ products && products.map((item, index) => {
return(
<Grid container justify="center" alignItems="center" key={index}>
<div className={classes.root}>
<Paper className={classes.paper}>
<Grid container spacing={2}>
<Grid item>
<ButtonBase className={classes.image}>
<img className={classes.img} alt="complex" src={item.image} />
</ButtonBase>
</Grid>
<Grid item xs={12} sm container>
<Grid item xs container direction="column" spacing={2}>
<Grid item xs>
<Typography gutterBottom variant="subtitle1">
{item.name}
</Typography>
<Typography variant="body2" gutterBottom>
{"Categoria: " + item.category}
</Typography>
<Typography variant="body2" color="textSecondary">
{item.description}
</Typography>
</Grid>
<Grid item>
<Button
onClick={(event) => removeFavorite(event, index)}>
<HighlightOff/> Eliminar de Favoritos
</Button>
</Grid>
</Grid>
<Grid item>
<Typography variant="subtitle1">{"Bs " + item.price + "/ Kg"}</Typography>
</Grid>
</Grid>
</Grid>
</Paper>
</div>
</Grid>
);
})
}
</ul>
</Fragment>
);
}
export default Favorites;
I think I am doing something wrong with the useEffect() when I perform the query and store it with the setProducts() fix. I don't know what's happening, why does it go blank and then rerun the Favorites component if it shows? I appreciate your help.
In the App component I have the Shopping Cart Sharp button, which redirects to "/ shoppingcart", which is the component where I have the problem.
const MyLink = React.forwardRef((props, ref) => <RouterLink innerRef={ref}
{...props} />);
function App() {
const [user, setUser] = useState(null);
const onLogout = () => {
setUser(null);
};
return (
<Router>
<CssBaseLine/>
<Header user={user}>
{user && <Button to="/shoppingcart" component={MyLink}
color="inherit"><ShoppingCartSharp /></Button>}
</Header>
<Routes/>
</Router>
);
}
export default App;
I am new to React and have been trying to look at this code for a while and can't figure out what could be wrong. I am getting an error saying that props is undefined when I try to console.log this.props to the screen.
Here is the code:
import React, { useState } from 'react';
import Grid from '#material-ui/core/Grid';
import InputField from 'shared/components/form/Inputfield';
import DatePicker from 'shared/components/pickers/DatePicker';
import InfoButton from 'shared/components/buttons/InfoButton';
import CustomButton from 'shared/components/buttons/CustomButton';
import TextArea from 'shared/components/form/TextArea';
import { connect } from 'react-redux';

});
const handleNameChange = full_project_name => event => {
console.log('Props of this object', this.props);
setValues({ ...values, [full_project_name]: event.target.value });
};
const handleShortNameChange = short_name => event => {
setValues({ ...values, [short_name]: event.target.short_name });
};
console.log('Project values', { values });
return (

}
export default connect(mapStateToProps)(ProjectDetails);
When the handleNameChange()-method is called props are undefined. I think I might be using connect wrong. Can anyone help me out?
In a functional component, you cannot access this
Try this instead:
export function ProjectDetails(props) {
const handleNameChange = full_project_name => event => {
console.log('Props of this object', props);
}
}
We get access to props from arguments of the function.
Have a read in react docs: https://reactjs.org/docs/components-and-props.html
I'm trying to achieve a specific layout using the Material UI Grid Component, but I just cannot for the life of me get it right.
I have a Dialog where I want the Layout to end up like this:
Where the blue box contains some information about a project, the green box will contain some sort of media and the yellow box will contain a descriptive text.
But currently, with this code, it ends up like this:
<Grid xl={12}>
<Grid spacing={0} xs={2}>
<Grid container direction="column">
<Grid item xs={1}>
{ this.getGridItems("Platforms", data["platforms"].split(','), true) }
</Grid>
<Grid item xs={1}>
{ this.getGridItems("Engines", data["engines"].split(','), true) }
</Grid>
<Grid item xs={1}>
{ this.getGridItems("Frameworks", data["frameworks"].split(','), true) }
</Grid>
<Grid item xs={1}>
{ this.getGridItems("Languages", data["languages"].split(',')) }
</Grid>
<Grid item xs={1}>
{ this.getGridItems("Roles", data["roles"].split(',')) }
</Grid>
</Grid>
</Grid>
<Grid spacing={0} xl={10}>
<Grid container>
<Grid item xl={9}>
<h1>Image Goes Here</h1>
</Grid>
<Grid item xl={3}>
<h1>Description</h1>
{ data["description"] }
</Grid>
</Grid>
</Grid>
</Grid>
I cannot quite figure out where I went wrong as I can't wrap my head around how the Grid layout works. Please help?
If it's necessary, here is the code for getGridItems():
getGridItems = (header, data, chips) => {
let list = [];
let fontSize = 11;
list.push(
<h5>{ header }</h5>
);
if(data.length > 0 && data[0] !== '') {
if(chips !== undefined && true) {
data.forEach(value => {
let chipData = ChipConstants[value];
list.push(
<Grid item xs>
<Chip
style={{ fontSize: fontSize}}
avatar={
<Avatar
style={{ width: 24, height: 24 }}
alt={chipData["avatar"]["alt"]}
src={require("../img/avatars/"+chipData["avatar"]["img"])}
/>}
label={chipData["avatar"]["alt"]}
className={styles.chip}
/>
</Grid>
);
});
} else {
data.forEach(value => {
list.push(
<Grid item xs style={{ fontSize: fontSize}}>
{ value }
</Grid>
);
});
}
} else {
list.push(
<Grid item xs style={{ fontSize: fontSize}}>
None
</Grid>
);
}
return list;
};
I'm not really seeing how your current code relates to what you want, so instead of trying to correct your current code, I'll just provide a starting point that provides the basic structure of what you want.
If you have specific questions about how the Grid in my code works, I'll elaborate as needed.
