从对象中删除 id 过滤器并使用 javascript 将其更改为简单格式

Question

我有 resultMp3 给我这个：

"mp3": {

  "33274": {

    "idSon": 33274,

    "description": "Techno Music",

    "Typenom": "Billboard",

  },

  "33275": {

    "idSon": 33275,

    "description": "Techno Music",

    "Typenom": "Pub Cd/Dvd",

  }

},

我想简单地按 id 删除过滤器，所以结果将是这样的

"mp3": {

  {

    "idSon": 33274,

    "description": "Techno Music",

    "Typenom": "Billboard",

  },

  {

    "idSon": 33275,

    "description": "Techno Music",

    "Typenom": "Pub Cd/Dvd",

  }

},

到目前为止，这是我的功能。结果没问题，但我的问题是我想删除 Id 并仍然使用它进行过滤：

let resultMp3 = {};

let sqlPromise = await new Promise(function (resolve, reject) {

  var ds = app.datasources.mydb;

  var sql = `....`;

  ds.connector.execute(sql, [], function (err, cm_comediens_extraits_mp3s) {

  if (cm_comediens_extraits_mp3s.length === 0){

    resultMp3 = {}

  }else{

    for(var i=0; i<cm_comediens_extraits_mp3s.length;i++){        

      let extraitMp3 = cm_comediens_extraits_mp3s[i];

      let mp3 = {};

      mp3["idSon"] = extraitMp3.idSon;

      mp3["description"] = extraitMp3.description;

      mp3["Typenom"] = valueList[extraitMp3.type].fr;

      resultMp3[extraitMp3.idSon] = mp3;   

    }

  }

   resolve(resultMp3);   

  }); 

});

result.mp3=resultMp3;

任何帮助，将不胜感激。

Answer 1

您可以使用 Object.valueslet data = { "mp3": {&nbsp; "33274": {&nbsp; &nbsp; "idSon": 33274,&nbsp; &nbsp; "description": "Techno Music",&nbsp; &nbsp; "Typenom": "Billboard",&nbsp; },&nbsp; "33275": {&nbsp; &nbsp; "idSon": 33275,&nbsp; &nbsp; "description": "Techno Music",&nbsp; &nbsp; "Typenom": "Pub Cd/Dvd",&nbsp; }}};let d = {"mp3" : Object.values(data.mp3)}console.log(d)

Answer 2

如果您的目标是制作对象数组，则可以使用 Object.values()let obj = {&nbsp; "mp3": {&nbsp; &nbsp; "33274": {&nbsp; &nbsp; &nbsp; "idSon": 33274,&nbsp; &nbsp; &nbsp; "description": "Techno Music",&nbsp; &nbsp; &nbsp; "Typenom": "Billboard",&nbsp; &nbsp; },&nbsp; &nbsp; "33275": {&nbsp; &nbsp; &nbsp; "idSon": 33275,&nbsp; &nbsp; &nbsp; "description": "Techno Music",&nbsp; &nbsp; &nbsp; "Typenom": "Pub Cd/Dvd",&nbsp; &nbsp; }&nbsp; }}obj.mp3 = Object.values(obj.mp3)console.log(obj)在您的情况下，您可以初始化resultMp3为数组（let resultMp3 = [];）并替换此行resultMp3[extraitMp3.idSon] = mp3;经过resultMp3.push(mp3);
