I am new to React and I am facing a issue to get item details when an item is clicked in React from an another Details component. I have MenuComponent.js which is supposed to call the DishDetailComponent.js when any of the card is clicked, however I am getting an error in my dish detail component when I do
const DishDetail = this.props( (selectedDish)=> { })
that the this.props is not a function. Here is the code from Menu Component used to call the DishDetail Component
import React, { Component } from 'react';
import { Media } from "reactstrap";
import { Card, CardImg, CardImgOverlay, CardText, CardBody, CardTitle } from
"reactstrap";
import DishDetail from './DishDetailComponent.js';
class Menu extends Component {
constructor(props) {
super(props);
this.state = {
selectedDish: null
};
}
onDishSelect(dish) {
this.setState({selectedDish: dish})
}
render() {
const menu = this.props.dishes.map((dish)=> {
return (
<div key={dish.id} className="col-12 col-md-5 m-1">
<Card onClick={()=>this.onDishSelect(dish)}>
<CardImg width="100%" src={dish.image} alt={dish.name} />
< CardImgOverlay>
<CardTitle>{dish.name}</CardTitle>
<p>{dish.description}</p>
</CardImgOverlay>
</Card>
</div>
);
});
return(
<div className="container">
<div className="row">
{menu}
</div>
<div className="row">
<DishDetail selectedDish={this.state.selectedDish}/>
</div>
</div>
);
}
}
export default Menu;
And here is my DishDetail Component that is giving me problems
import React, { Component } from 'react';
import { Card, CardImg, CardImgOverlay, CardText, CardBody, CardTitle } from
"reactstrap";
class DishDetail extends Component{
constructor(props) {
super(props);
}
render() {
const DishDetail = this.props( (selectedDish)=> {
if (selectedDish != null) {
return (
<Card>
<CardImg width="100%" src={selectedDish.image} alt={selectedDish.name} />
<CardBody>
<CardTitle>{selectedDish.name}</CardTitle>
<CardText>{selectedDish.description}</CardText>
</CardBody>
</Card>
)
} else {
return (
<div></div>
);
}
});
return (
<div className="container">
<div className="row">
{DishDetail}
</div>
</div>
)
}
}
export default DishDetail;
Thanks
This should works:
import React, { Component } from 'react';
import { Card, CardImg, CardImgOverlay, CardText, CardBody, CardTitle } from
'reactstrap';
class DishDetail extends Component{
constructor(props) {
super(props);
}
renderDish(dish) {
if (dish != null)
return(
<Card>
<CardImg top src={dish.image} alt={dish.name} />
<CardBody>
<CardTitle>{dish.name}</CardTitle>
<CardText>{dish.description}</CardText>
</CardBody>
</Card>
);
else
return(
<div></div>
);
}
render() {
return (
<div className="container">
<div className="row">
{this.renderDish(this.props.selectedDish)}
</div>
</div>
)
}
}
export default DishDetail;
this.props
is not a function, it is an object. Try to write your DishDetail
like that.
import React, { Component } from 'react'; import { Card, CardImg, CardImgOverlay, CardText, CardBody, CardTitle } from "reactstrap"; class DishDetail extends Component{ constructor(props) { super(props); } render() { const { selectedDish } = this.props; const DishDetail = () => { if (selectedDish) { return ( <Card> <CardImg width="100%" src={selectedDish.image} alt={selectedDish.name} /> <CardBody> <CardTitle>{selectedDish.name}</CardTitle> <CardText>{selectedDish.description}</CardText> </CardBody> </Card> ) } return ( <div /> ); } return ( <div className="container"> <div className="row"> {DishDetail} </div> </div> ) } } export default DishDetail;
import React, { Component } from 'react';
import { Card, CardImg, CardImgOverlay, CardText, CardBody, CardTitle } from
"reactstrap";
const DishDetail = ({ selectedDish }) => {
return (
<div className="container">
<div className="row">
{ selectedDish &&
<Card>
<CardImg width="100%" src={selectedDish.image} alt={selectedDish.name} />
<CardBody>
<CardTitle>{selectedDish.name}</CardTitle>
<CardText>{selectedDish.description}</CardText>
</CardBody>
</Card>
}
</div>
</div>
)
};
export default DishDetail;
The purpose of this component is to display information, so the functional component is a better choice here (instead of the class), but there is no restriction on this, just a recommendation. Try to walk through the code and understand it, do not worry to ask questions if there are any..
