Question

我有一个带有嵌套对象的JSON。看起来像这样：

var cars = [
    {
        "id":1,
        "name":"Ford Focus", 
        "attributes":{
            "color":"gray",
            "speed":"200"
        }
    },
    {
        "id":2,
        "name":"Ford Fiesta", 
        "attributes":{
            "color":"red",
            "speed":"180"
        }
    },
];

我想按嵌套对象中的值进行过滤（例如，所有带有绿色的汽车）。

Answer 1

使用filter()方法

var cars = [
    {
        "id":1,
        "name":"Ford Focus", 
        "attributes":{
            "color":"gray",
            "speed":"200"
        }
    },
    {
        "id":2,
        "name":"Ford Fiesta", 
        "attributes":{
            "color":"red",
            "speed":"180"
        }
    },
]; 

console.log(cars.filter(car => car.attributes.color === 'red'));
