JavaScript:通过链接两个数组创建一个 JSON 对象数组
javascriptweb developmentfront end technologyobject oriented programmingjson
假设我们有两个像这样的数组 −
const meal = ["breakfast", "lunch", "dinner"]; const ingredients = [ ["eggs", "yogurt", "toast"], ["falafel", "mushrooms", "fries"], ["pasta", "cheese"] ];
我们需要编写一个 JavaScript 函数，该函数接受两个这样的数组，并将第二个数组中的子数组映射到第一个数组的相应字符串。
因此，上述数组的输出应如下所示 −
const output = {
"breakfast" : ["eggs", "yogurt", "toast"],
"lunch": ["falafel", "mushrooms", "fries"],
"dinner": ["pasta", "cheese"]
};
示例
其代码为 −
const meals = ["breakfast", "lunch", "dinner"];
const ingredients = [
["eggs", "yogurt", "toast"],
["falafel", "mushrooms", "fries"],
["pasta", "cheese"]
];
const combineMealAndIngredient = (meals, ingredients) => {
const res = {};
meals.forEach(function (el, ind) {
this[el] = ingredients[ind];
}, res);
return res;
};
console.log(combineMealAndIngredient(meals, ingredients));
输出
控制台中的输出将是 −
{
breakfast: [ 'eggs', 'yogurt', 'toast' ],
lunch: [ 'falafel', 'mushrooms', 'fries' ],
dinner: [ 'pasta', 'cheese' ]
}
