如何映射包含数组的对象

Question

我是 javascript 新手，所以我有一个包含三个数组的对象，我想映射它并列出我的数据    const [Foods,setFoods] = useState({      "id_food":[1,2,3],      "name_food":["food1","food2","food3"],      "quantity":[10,22,12]  })一个虚构的代码：{ Foods.map((id,name,qte) =>(    <p>{id}{name}{qte}</p> ))}

Answer 1

  Object.keys(Foods).forEach(prop => {
      Foods[prop].map((item) => console.log(item));
  });

Answer 2

也许是这样的：

Foods.id_food.map((id, i) => {

    const name_food = Foods.name_food[i];

    const quantity = Foods.quantity[i];

    return  <AwesomeReactComponent key={id} nameFood={name_food} quantity={quantity}/>;

});

Answer 3

let mappedArray = Foods.id_food.map((ele, i) => {

    let name = Foods.name_food[i]

    let quantity = Foods.quantity[i]

    return {id: ele, name: name, quantity: quantity}

})

输出：

(3) [{…}, {…}, {…}]

0: {id: 1, name: "food1", quantity: 10}

1: {id: 2, name: "food2", quantity: 22}

2: {id: 3, name: "food3", quantity: 12}
