Javascript 用缺少的对象和值填充数组

Question

我有一个像下面这样的数组，每个索引包含不同的对象集，我想创建一个统一的数据，其中每个索引中缺少的对象将具有 Value:0 ，

var d = [
          [
            {axis:"Email",value:59,id:1},
            {axis:"Social Networks",value:56,id:2},

          ],
          [

            {axis:"Sending Money",value:18,id:6},
            {axis:"Other",value:15,id:7},

          ]
        ];

如何使用上面的数组获得如下所示的数组

var d = [
          [
            {axis:"Email",value:59,id:1},
            {axis:"Social Networks",value:56,id:2},
            {axis:"Sending Money",value:0,id:6},
            {axis:"Other",value:0,id:7},

          ],
          [
            {axis:"Email",value:0,id:1},
            {axis:"Social Networks",value:0,id:2},
            {axis:"Sending Money",value:18,id:6},
            {axis:"Other",value:15,id:7},

          ]
        ];

有两个功能:

getAllEntries 找到所有对象并将它们存储到变量 accEntries 中。然后 accEntries 用于搜索 d 的子数组中的所有事件。整个过程在 checkArray 中完成。

checkArray 用于获取 d 中所有已找到和未找到的条目。然后使用两个数组(找到的和未找到的)构建一个新的子数组，该子数组包含具有特定值的已找到条目和/或值为 0 的未找到条目。

希望对您有所帮助:

var d = [
  [
  {
    axis: 'Email',
    value: 59,
    id: 1
  },
  {
    axis: 'Social Networks',
    value: 56,
    id: 2
  },
  ],
  [
    {
      axis: 'Sending Money',
      value: 18,
      id: 6
    },
    {
      axis: 'Other',
      value: 15,
      id: 7
    },
  ]
];
  

function getAllEntries(array) {
  var uniqueEntries = [];
  array.forEach(function (subarray) {
    subarray.forEach(function (obj) {
      if (uniqueEntries.indexOf(obj) === - 1) uniqueEntries.push(obj);
    });
  });
  return uniqueEntries;
}


function checkArray(array, acceptedEntries) {
  var result = [];
  array.forEach(function (subArray) {
    var subResult = [];
    var foundEntries = [];
    subArray.forEach(function (obj) {
      if (foundEntries.indexOf(obj.axis) === - 1) foundEntries.push(obj.axis);
    });
    var notFound = acceptedEntries.filter(function (accepted) {
      return foundEntries.indexOf(accepted.axis) === - 1;
    });
    foundEntries.forEach(function (found) {
      subArray.forEach(function (obj) {
        if (obj.axis === found) subResult.push(obj);
      });
    });
    notFound.forEach(function (notfound, index) {
      subResult.push({
        axis: notfound.axis,
        value: 0,
        id: notfound.id
      });
    });
    result.push(subResult);
  });
  return result;
}


var accEntries = getAllEntries(d);
var result = checkArray(d, accEntries);
console.log(result);
