Javascript 从JSON获取特定对象

我有这个：

'{
"Games": [
    {   "champion": 126,
        "season": 9
    },
    {
        "champion": 126,
        "season": 9
    }, {
        "champion": 126,
        "season": 8
    }`

我只想拿第九季的冠军号码。我该怎么做呢？

您可以使用

数组。查找
：

const champion = data.Games.find(({season}) => season === 9)

或ES5

var champion = data.Games.find(function(champion) {
   return champion.season === 9;
});

   return champion.season === 9;
});

我相信您必须使用条件逻辑对数组进行迭代，以捕获并返回您要查找的任何值

比如：

for (var i = 0; i < Games.length; i++) {
    if (Games[i].season == 9) {
        return(Games[i].champion);
    }
}

for（变量i=0；i

使用Array.filter（）

或者在Es6中

let season9 = Games.filter(elem => elem.season === 9);

let champions = season9.map(elem => elem.champion);

console.log(champions) // => [126, 126]

然后

或者在Es6中

let season9 = Games.filter(elem => elem.season === 9);

let champions = season9.map(elem => elem.champion);

console.log(champions) // => [126, 126]

let season9 = Games.filter(elem => elem.season === 9);

let champions = season9.map(elem => elem.champion);

let season9 = Games.filter(elem => elem.season === 9);

let champions = season9.map(elem => elem.champion);

console.log(champions) // => [126, 126]

请发布完整有效的json数据。For循环。你试过什么吗？你希望输出结果是什么<代码>[126126]

？让结果=Games.filter（elem=>elem.seasure==9）。map（elem=>elem.champion）；让结果=Games.filter（elem=>elem.seasure==9）.map（elem=>elem.champion）；
