javascript - 如何展示单个产品？

Question

美好的一天，
我想问你可以在React中显示一个产品卡/页面。
我已经尝试过了，但是没有成功。先感谢您:

 const product = products.find(x=> x.id === props.match.params.id)
    
    return(
        <div>
        <Nav/>
        <h1>product page</h1>
        <p>{Product.name}</p>

)
产品代码页:

import React from 'react'
import Product from '../components/product'
import Nav from "../components/nav"
import Store from './store'
import products from '../data/products'

function ProductPage(props){
    console.log(props.match.params.id)
    const product = products.find(x=> x.id === props.match.params.id)
    
    return(
        <div>
        <Nav/>
        <h1>product page</h1>
        <p>{Product.name}</p>
        
       
   

  
        
      
        

        </div>
    )
}

export default ProductPage

产品卡代码:

import React from 'react'
import Products from '../data/products'
import {Link} from 'react-router-dom'
function Product(props){
    function HandleSubmit(e){
        e.preventDefault()
        alert('added to cart !')
        
    }
    return(
        <div >
           <ul className="products">
            {Products.map(product=> (<li key={product.id} className="product">
                <img src={product.img}></img>
               <a   href={"/product:" + product.id}><h1>{product.name}</h1></a> 
                <p>price: €{product.price}</p>
                <form onSubmit={HandleSubmit}>
                <button>Add to cart</button> 
                </form>
                
                </li> 
                )

                )}
                </ul>
        </div>
    )
}

Answer 1

我在以下位置看到了错误:ProductPage。如果要显示产品名称。应该是:

<p>{product.name}</p>

或者您想显示产品卡:

  <div>
    <Nav/>
    <h1>product page</h1>
    <p>{product.name}</p>
    <Product/>
</div>
