如何仅从具有“RANKED_SOLO_5x5”而不是“RANKED_FLEX_SR”的 json 部分获取信息（“tier”、“rank”、“leaguePoints”）

Question

json

[

}

如果您知道 arr 中 object 的索引并且您知道它不会改变，那么您可以使用index获取 object 然后对其进行解构

const { tier, rank, leaguePoints } = arr[1];
console.log(tier, rank, leaguePoints);

 const arr = [ { leagueId: "51f35167-0e62-41b0-bb5d-8ec376e754d7", queueType: "RANKED_FLEX_SR", tier: "GOLD", rank: "II", summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg", summonerName: "Impermanencë", leaguePoints: 1, wins: 7, losses: 5, veteran: false, inactive: false, freshBlood: false, hotStreak: false, }, { leagueId: "0e4412d1-81c2-4839-9045-c0cb556ebdcb", queueType: "RANKED_SOLO_5x5", tier: "PLATINUM", rank: "III", summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg", summonerName: "Impermanencë", leaguePoints: 75, wins: 222, losses: 205, veteran: false, inactive: false, freshBlood: false, hotStreak: false, }, ]; const { tier, rank, leaguePoints } = arr[1]; console.log(tier, rank, leaguePoints);

否则你需要使用find来获取元素然后解构。

const obj = arr.find((o) => o.queueType === "RANKED_SOLO_5x5");
const { tier, rank, leaguePoints } = obj;
console.log(tier, rank, leaguePoints);

 const arr = [ { leagueId: "51f35167-0e62-41b0-bb5d-8ec376e754d7", queueType: "RANKED_FLEX_SR", tier: "GOLD", rank: "II", summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg", summonerName: "Impermanencë", leaguePoints: 1, wins: 7, losses: 5, veteran: false, inactive: false, freshBlood: false, hotStreak: false, }, { leagueId: "0e4412d1-81c2-4839-9045-c0cb556ebdcb", queueType: "RANKED_SOLO_5x5", tier: "PLATINUM", rank: "III", summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg", summonerName: "Impermanencë", leaguePoints: 75, wins: 222, losses: 205, veteran: false, inactive: false, freshBlood: false, hotStreak: false, }, ]; const obj = arr.find((o) => o.queueType === "RANKED_SOLO_5x5"); const { tier, rank, leaguePoints } = obj; console.log(tier, rank, leaguePoints);
