Javascript 扫描嵌套对象'；匹配数组

我有一个像这样的物体-

{
"Campaigns":
{
"Campaign1":
{
    "reports":
        [
            {
                "month": "Google - January - Monthly Report.csv",
                "impressions": 53,
                "clicks": 31,
                "cost": 18
            },
            {
                "month": "Google - April - Monthly Report.csv",
                "impressions": 13,
                "clicks": 11,
                "cost": 8
            }
        ]
    },
"Campaign2":
{
    "reports":
        [
            {
                "month": "Google - March - Monthly Report.csv",
                "impressions": 13,
                "clicks": 11,
                "cost": 8
            }
        ]
}
}

}

我还有一个附加的数组和文件名。。让我们以这个数组为例-

reports_array = [
                 'Google - January - Monthly Report.csv',
                 'Google - February - Monthly Report.csv',
                 'Google - March - Monthly Report.csv',
                 'Google - April - Monthly Report.csv'
                 ]

我希望完成的是扫描每个活动中的“缺失”报告（在本例中为“活动1”和“活动2”），并在所有属性（印象、点击、成本）中推送一个包含零的新报告，因此，除了“一月和四月报告”，活动1将包含二月和三月报告，只有零而不是真实数据。此外，campaign2还将发布另外三份报告（1月、2月和4月），报告中的数据也将为零，而不是真实数据

到目前为止我所做的尝试（不太成功）-

这里有一种方法：

var campaigns = campaigns_object.Campaigns;

Object.keys(campaigns)
  .forEach(function(campaign) {
    reports_array.forEach(function(report, index) {
      var has_report = campaigns[campaign].reports.some(function(campaign_report) {
        return (campaign_report.month === report);
      });

      if (!has_report) {
        campaigns[campaign].reports.splice(index, 0, {
            month: report,
          impressions: 0,
          clicks: 0,
          cost: 0
        });
      }
    });
  });

console.log(campaigns);

这会给你这个结果：

{
  "Campaign1": {
    "reports": [
      {
        "month": "Google - January - Monthly Report.csv",
        "impressions": 53,
        "clicks": 31,
        "cost": 18
      },
      {
        "month": "Google - February - Monthly Report.csv",
        "impressions": 0,
        "clicks": 0,
        "cost": 0
      },
      {
        "month": "Google - March - Monthly Report.csv",
        "impressions": 0,
        "clicks": 0,
        "cost": 0
      },
      {
        "month": "Google - April - Monthly Report.csv",
        "impressions": 13,
        "clicks": 11,
        "cost": 8
      }
    ]
  },
  "Campaign2": {
    "reports": [
      {
        "month": "Google - January - Monthly Report.csv",
        "impressions": 0,
        "clicks": 0,
        "cost": 0
      },
      {
        "month": "Google - February - Monthly Report.csv",
        "impressions": 0,
        "clicks": 0,
        "cost": 0
      },
      {
        "month": "Google - March - Monthly Report.csv",
        "impressions": 13,
        "clicks": 11,
        "cost": 8
      },
      {
        "month": "Google - April - Monthly Report.csv",
        "impressions": 0,
        "clicks": 0,
        "cost": 0
      }
    ]
  }
}

功能填充（活动、报告）{
对于（活动中的var键）{//对于活动对象中的每个活动
reports.filter（函数（report）{//过滤掉缺少的报告
返回活动[key].reports.every（函数（creport）{//如果此活动的报告数组中的每个报告都不等于此报告，则认为缺少此报告
返回creport.month！==报告；
});
}).forEach（函数（报表）{//然后针对缺少的报表数组中的每个报表
活动[key].reports.push（{//push一个新的空白报告
“月”：报告，
“印象”：0，
“点击”：0，
“成本”：0
});
});
}
}

console.log（活动\u对象）插入顺序重要吗？？？插入顺序重要吗？？？
