how often does the letter "o" occur in:
q: как забрасывать данные из одной компоненты в другую у меня есть 2 компонента: product_details и cart - моя корзина с элементами. я пытаюсь забрасывать по кнопке buy их в корзину и отрисовывать их, как в обычном магазине. когда я нажимаю на кнопку buy, у меня только вызывается ошибка в консоли expected onclick listener to be a function, instead got a value of object type. , данные в компоненте cart не рисуются, но приложение дальше работает. как можно забрасывать эти данные в компоненту cart?
cart.js
import react from "react";
import {useselector} from "react-redux";

export let cart = () => {

let {id, title, description, image} = useselector(
    (state) => state.products_reducer.cart_products_list)

return (<div>
    <div key={id}>
        <p>{title}</p>
    </div>
</div>)
}

action_creators.js
import {
products_are_loaded,
different_product_are_loaded,
add_to_cart,
} from "./action_types";

let products_are_loaded = (payload) => ({type: products_are_loaded, payload})
let different_product_are_loaded = (payload) => ({type: different_product_are_loaded, payload})
let add_to_cart = (payload) => ({type: add_to_cart, payload})

export {
products_are_loaded,
different_product_are_loaded,
add_to_cart
}

reducers.js
import {
products_are_loaded,
different_product_are_loaded,
add_to_cart,
remove_from_cart} from "./action_types";

let initialstate = {
all_products : [],
different_product : [],
cart_products_list : []
}

let products_reducer = (state = initialstate, action) => {
switch (action.type) {
    case products_are_loaded : {
        return {
            ...state,
            all_products: action.payload
        }
    }
    case different_product_are_loaded : {
        return {
            ...state,
            different_product: action.payload
        }
    }

    case add_to_cart : {
        return {
            ...state,
            cart_products_list: [...state.cart_products_list, action.newitem]
        }
    }

    default:
        return state;
}
}
export default products_reducer;

product_detail.js
import react, {useeffect} from "react";
import {useparams} from "react-router-dom";
import {usedispatch, useselector} from "react-redux";
import {add_to_cart, different_product_are_loaded} from "../redux/action_creators";

export let product_detail = () => {

let {id} = useparams();
let dispatch = usedispatch();
let {title, description, image} = useselector(
    (state) => state.products_reducer.different_product);

let fetchproductdifferent = async () => {
    try {
        let response = await fetch(`https://fakestoreapi.com/products/${id}`)
        let json = await response.json();
        dispatch(different_product_are_loaded(json));
    } catch (error) {
        console.log(error);
    }
}

useeffect(() => {
    fetchproductdifferent()
},[])

return (<div classname="product_detail_page">
    <div key={id} classname="product_detail">
            <div>
                <h2>{title}</h2>
                <img src={image}/>
            </div>
            <div>
                <p>{description}</p>
            </div>
            <button onclick={dispatch(add_to_cart(id))}>buy</button>
    </div>
        </div>)
}


a: action.newitem не имеет никакого значения. в reducers.js необходимо обновить данное место:
case add_to_cart: {
      const newitem = state.all_products.find(
        (item) => item.id == action.payload
      );
      return {
        ...state,
        cart_products_list: [...state.cart_products_list, newitem],
      };
    }

card.js:
import react from "react";
import { useselector } from "react-redux";

export const cart = () => {
  const cartproductslist = useselector(
    (state) => state.products_reducer.cart_products_list
  );

  return (
    <div>
      {cartproductslist.map(({ id, title, description, image }) => (
        <div key={id}>
          <p>{title}</p>
          <p>{description}</p>
          <img src={image} alt={`product ${id}`} style={{ maxwidth: "100px" }}/>
        </div>
      ))}
    </div>
  );
};
