【问题描述】：

我有一个包含重复键的 JSON 文件，我想将重复键及其值合并到一个记录中。

例子：

Json 看起来像这样：

{
  "numbers": {
    "0BJA10GH001": {
      "links": [
        {
          "name": "RI-Fliessbild: RG MFB L3 RI_002",
          "path": "/C1_RI-Fliessbilder/C1.1/3/RG MFB L3 RI_002.pdf",
          "searchNumber": true
        },
        {
          "name": "Katalog Sensor: TGM / siehe 0BJA10GH001 -1_5.1",
          "path": "/1_Verfahrenstechnik/Teil B/1_B5/1_B5.1/01_0BJA10GH001.pdf",
          "searchNumber": false
        },
        {
          "name": "Datenblatt: 0BJA10GH001",
          "path": "/Datenblaetter Messstellenliste/RG MFB L3 RI_002/0BJA10GH001.pdf",
          "searchNumber": false
        }
      ],
      "aliases": [
        "0BJA10GH001"
      ]
    },


"0BJA10GH001": {
  "links": [
    {
      "name": "RI-Fliessbild: RG MFB L3 RI_002",
      "path": "/C1_RI-Fliessbilder/C1.1/3/RG MFB L3 RI_002.pdf",
      "searchNumber": true
    },
    {
      "name": "Komponentenbeschreibung: TGM / ---",
      "path": "/1_Verfahrenstechnik/Teil B/1_B5/1_B5.1/01_0BJA10GH001.pdf",
      "searchNumber": false
    },
    {
      "name": "Datenblatt: 0BJA10GH001",
      "path": "/Datenblaetter Apparateliste/RG MFB L3 RI_002/0BJA10GH001.pdf",
      "searchNumber": false
    }
  ],
  "aliases": [
    "0BJA10GH001"
  ]
}

} }

我希望它看起来像这样：

{
  "numbers": {
    "0BJA10GH001": {
      "links": [
        {
          "name": "RI-Fliessbild: RG MFB L3 RI_002",
          "path": "/C1_RI-Fliessbilder/C1.1/3/RG MFB L3 RI_002.pdf",
          "searchNumber": true
        },
        {
          "name": "Katalog Sensor: TGM / siehe 0BJA10GH001 -1_5.1",
          "path": "/1_Verfahrenstechnik/Teil B/1_B5/1_B5.1/01_0BJA10GH001.pdf",
          "searchNumber": false
        },
        {
          "name": "Datenblatt: 0BJA10GH001",
          "path": "/Datenblaetter Messstellenliste/RG MFB L3 RI_002/0BJA10GH001.pdf"
        },
        {
          "name": "Komponentenbeschreibung: TGM / ---",
          "path": "/1_Verfahrenstechnik/Teil B/1_B5/1_B5.1/01_0BJA10GH001.pdf",
          "searchNumber": false
        },
        {
          "name": "Datenblatt: 0BJA10GH001",
          "path": "/Datenblaetter Apparateliste/RG MFB L3 RI_002/0BJA10GH001.pdf",
          "searchNumber": false
        }
      ],
      "aliases": [
        "0BJA10GH001"
      ]
    }
  }
}

两个键“0BJA10GH001”是相同的合并，里面的重复值被删除。

function combine(arr) {
  var combined = arr.reduce(function(result, item) {
    var current = result[item.key];


    result[item.key] = !current ? item : {
      kks: item.key,
    };

    return result;
  }, {});

  return Object.keys(combined).map(function(key) {
    return combined[key.key];
  });
}

var result = combine(SeatWithCat);

console.log(result);
document.write(JSON.stringify(result));

到目前为止，这是我的代码，它适用于第一部分。它删除了双键“0BJA10GH001”，但数组中的值不会从重复键中加入。

每个键“0BJA10GH001”内部都有一个“链接”数组，当重复项合并时，这些“链接”数组应该相互连接。

重复键“0BJA10GH001”内的所有值都应加入一个数组。我怎样才能做到这一点？更进一步，如何删除数组中的重复项？

非常感谢。

【问题讨论】：

请格式化您的答案，尤其是代码块。
javascript 对象中不能有重复的键。你的对象是错误的。
我想通过将重复项与对应项合并来删除它们。
@silvankaufmann 您的意思是要将“0BJA10GH001”值合并到“0BJA10GsH001”？
尝试看看这个解决方案https://stackoverflow.com/a/8432188/2268099希望这会有所帮助。

标签： javascript json merge duplicates

【解决方案1】：

查找重复键代码：

var data = yourJson.numbers;
var keys = Object.keys(data);
var sizeOfData = keys.length;
for (var i=0; i < sizeOfData-1; i++){
 for (var j=i; j< sizeOfData-1; j++){
        if(keys[i] == keys[j+1]){
             // here i and j+1 have same key and need another algo for merge
        }
    }
}
