查询JSON类型中的数组元素

{
  "fruits": [
    { "name": "Apple", "color": "Red" },
    { "name": "Banana", "color": "Yellow" },
    { "name": "Grape", "color": "Purple" }
  ]
}

const jsonData = {
  "fruits": [
    { "name": "Apple", "color": "Red" },
    { "name": "Banana", "color": "Yellow" },
    { "name": "Grape", "color": "Purple" }
  ]
};

// 查询第一个水果的名称
const firstFruitName = jsonData.fruits[0].name;
console.log(firstFruitName); // 输出: Apple

// 查询所有红色的水果
const redFruits = jsonData.fruits.filter(fruit => fruit.color === "Red");
console.log(redFruits); // 输出: [{ "name": "Apple", "color": "Red" }]

const jsonString = '{"fruits": [{"name": "Apple", "color": "Red"}, {"name": "Banana", "color": "Yellow"}]}';
const jsonData = JSON.parse(jsonString);

// 现在可以安全地访问jsonData.fruits
console.log(jsonData.fruits[0].name); // 输出: Apple
