javascript - 如何通过匹配id将数组插入对象

Question

我从 api 返回一个对象数组，其中包含 currentDataResult 和 PastDataResult。

[
{
    "sectionCurrentDataResult": [
        {
            "section_id": 14785,
            "subdivision_name": "Stratton Woods",
        },
        {
            "section_id": 14790,
            "subdivision_name": "Stratton Woods",
        },
        {
            "section_id": 14791,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14792,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14781,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14786,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14787,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14788,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14782,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14783,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 14784,
            "subdivision_name": "Stratton Woods"
        },
        {
            "section_id": 5326,
            "subdivision_id": 1439,
            "subdivision_name": "Stratton Woods"
        }
    ]
},
{
    "sectionPastDataResult": [
        {
            "section_id": 5326,
            "price_min": 177,
            "price_max": 235
        },
        {
            "section_id": 14785,
            "price_min": 190,
            "price_max": 220
        },
        {
            "section_id": 14786,
            "price_min": 238,
            "price_max": 292
        },
        {
            "section_id": 14788,
            "price_min": 186,
            "price_max": 205
        },
        {
            "section_id": 14790,
            "price_min": 150,
            "price_max": 269
        },
        {
            "section_id": 14783,
            "price_min": 150,
            "price_max": 260
        },
        {
            "section_id": 14787,
            "price_min": 90,
            "price_max": 90
        },
        {
            "section_id": 14792,
            "price_min": 177,
            "price_max": 235
        },
        {
            "section_id": 14791,
            "price_min": 145,
            "price_max": 221
        },
        {
            "section_id": 14784,
            "price_min": 148,
            "price_max": 186
        },
        {
            "section_id": 14781,
            "price_min": 155,
            "price_max": 200
        },
        {
            "section_id": 14782,
            "price_min": 150,
            "price_max": 170
        }
      ]
    }
  ]

我需要将匹配的过去数据对象(按section_id)对象作为嵌套数组推送到当前数据结果对象中。这就是它需要的样子

"sectionCurrentDataResult": [
        {
            "section_id": 14785,
            "subdivision_name": "Stratton Woods",
            "sectionHistory":[{
               "section_id": 14785,
               "price_min": 190,
               "price_max": 220
            }]
        },
        {
            "section_id": 14790,
            "subdivision_name": "Stratton Woods",
            "sectionHistory":[{
               "section_id": 14790,
               "price_min": 150,
               "price_max": 269
            }]
        },
        etc....
        ]

我创建了一个服务，它获取当前和过去的数据结果，并对过去的数据结果重新排序以匹配当前的数据结果。我需要帮助的是将过去的数据数组插入当前的数据对象。现在，它错误地将整个过去的数据数组插入当前数据数组的第一个对象中。我已经用我的代码设置了一个plunker。

plunker

app.controller('MainCtrl', function($scope,bigEnchilada,inputHistorySvc) {

   for (var i = 0; i < bigEnchilada[0].sectionCurrentDataResult.length; i++) {
        bigEnchilada[0].sectionCurrentDataResult[i].sectionHistory =  inputHistorySvc.historyInputs(bigEnchilada);
        }
      $scope.sections = bigEnchilada[0].sectionCurrentDataResult;

    });

Answer 1

这是您要找的吗？

var app = angular.module('angularjs-starter', []);

app.controller('MainCtrl', function($scope,bigEnchilada,inputHistorySvc) {
var list = inputHistorySvc.historyInputs(bigEnchilada);
for (var i = 0; i < bigEnchilada[0].sectionCurrentDataResult.length; i++){
   for (var j = 0; j < list.length; j++ ) {
      if(bigEnchilada[0].sectionCurrentDataResult[i].section_id ==      list[j].section_id){
          bigEnchilada[0].sectionCurrentDataResult[i].sectionHistory = list[j];
      }
   }
}
  $scope.sections = bigEnchilada[0].sectionCurrentDataResult;

});

输出:

[
{
"section_id": 14785,
"subdivision_name": "Stratton Woods",
"sectionHistory": {
  "section_id": 14785,
  "price_min": 190,
  "price_max": 220
}
},
{
"section_id": 14790,
"subdivision_name": "Stratton Woods",
"sectionHistory": {
  "section_id": 14790,
  "price_min": 150,
  "price_max": 269
}
},
 {
"section_id": 14791,
"subdivision_name": "Stratton Woods",
"sectionHistory": {
  "section_id": 14791,
  "price_min": 145,
  "price_max": 221
}
},

等等
