我試圖做的這個(gè)特別期望的結(jié)果結(jié)果證明比我對(duì)剛開始編程的人所期望的更具挑戰(zhàn)性。我將 API 查詢的結(jié)果存儲(chǔ)在如下所示的數(shù)組變量中：[{  balance: 4444,  playerInfo: {    age: "18",    gender: "Male",    level: "2",    name: "Joe"  }}, {  balance: 3333,  playerInfo: {    age: "45",    gender: "Male",    level: "3",    name: "Angel"  }}, {  balance: 2222,  playerInfo: {    age: "20",    gender: "Female",    level: "11",    name: "Luce"  }}]我想要的結(jié)果是：[{  balance: 4444,  level: "2",  name: "Joe"}, {  balance: 3333,  level: "3",  name: "Angel"}, {  balance: 2222,  level: "11",  name: "Luce"}]我在 flat 和 flatMap 方面取得了一些小進(jìn)展，但不完全確定它是否是實(shí)現(xiàn)兼容性的正確方法，因?yàn)轭A(yù)期的目標(biāo)群體可能正在使用過時(shí)的瀏覽器。其他一些答案的邏輯對(duì)我來說有點(diǎn)難以理解 atm 所以希望能提供一些建議以防萬(wàn)一

您可以使用Array.map和Object destructuring。

let data = [{balance:4444,playerInfo:{age:"18",gender:"Male",level:"2",name:"Joe"}},{balance:3333,playerInfo:{age:"45",gender:"Male",level:"3",name:"Angel"}},{balance:2222,playerInfo:{age:"20",gender:"Female",level:"11",name:"Luce"}}]


const formatData = (data) => {

? return data.map(({balance, playerInfo}) => ({

? ? balance,

? ? level: playerInfo.level,

? ? name: playerInfo.name

? }))

}


console.log(formatData(data))


let data = [{balance:4444,playerInfo:{age:"18",gender:"Male",level:"2",name:"Joe"}},{balance:3333,playerInfo:{age:"45",gender:"Male",level:"3",name:"Angel"}},{balance:2222,playerInfo:{age:"20",gender:"Female",level:"11",name:"Luce"}}]


const formatData = (data) => {

? return data.map(({ balance, playerInfo: { level, name }}) => ({

? ? balance,

? ? level,

? ? name

? }))

}


console.log(formatData(data));

簡(jiǎn)短的'n甜蜜是這樣的：


let rawData = [{

  balance: 4444,

  playerInfo: {

    age: "18",

    gender: "Male",

    level: "2",

    name: "Joe"

  }

}, {

  balance: 3333,

  playerInfo: {

    age: "45",

    gender: "Male",

    level: "3",

    name: "Angel"

  }

}, {

  balance: 2222,

  playerInfo: {

    age: "20",

    gender: "Female",

    level: "11",

    name: "Luce"

  }

}]


let formattedData =

  rawData.map(({

    balance,

    playerInfo: {

      level,

      name

    }

  }) => ({ balance, level, name }))


console.log(formattedData)

您可以直接使用map方法進(jìn)行轉(zhuǎn)換。


let input = [{

  balance: 4444,

  playerInfo: {

    age: "18",

    gender: "Male",

    level: "2",

    name: "Joe"

  }

}, {

  balance: 3333,

  playerInfo: {

    age: "45",

    gender: "Male",

    level: "3",

    name: "Angel"

  }

}, {

  balance: 2222,

  playerInfo: {

    age: "20",

    gender: "Female",

    level: "11",

    name: "Luce"

  }

}];

let output = input.map(obj => ({

  balance: obj.balance,

  level: obj.playerInfo?.level,

  name: obj.playerInfo?.name,

}));


console.log(output);
