    FileVolumeNumber: "E312534.2",
    Type: "Manufacturer",
    FileNumber: "E312534"
  },
  {
    ApplicantPartySiteNumber: "1095651",
    ManufacturerPartySiteNumber: null,
    FileVolumeNumber: "E63418.1",
    Type: "Applicant",
    FileNumber: "E63418"
  },
  {
    ApplicantPartySiteNumber: "1095651",
    ManufacturerPartySiteNumber: null,
    FileVolumeNumber: "E61772.2",
    Type: "Applicant",
    FileNumber: "E61772"
  }
];

Answer 1

尝试一下：

const data = [{  
      "ApplicantPartySiteNumber":"60229",
      "ManufacturerPartySiteNumber":"1095651",
      "FileVolumeNumber":"E312534.2",
      "Type":"Manufacturer",
      "FileNumber":"E312534"
   },
   {  
      "ApplicantPartySiteNumber":"1095651",
      "ManufacturerPartySiteNumber":null,
      "FileVolumeNumber":"E63418.1",
      "Type":"Applicant",
      "FileNumber":"E63418"
   },
   {  
      "ApplicantPartySiteNumber":"1095651",
      "ManufacturerPartySiteNumber":null,
      "FileVolumeNumber":"E61772.2",
      "Type":"Applicant",
      "FileNumber":"E61772"
   }]
   
   const result =  data.map(res=>({'FileNumber': res['FileNumber'], 'FileVolumeNumber': res['FileVolumeNumber']}));
   
   console.log(result)

您的json中缺少括号，说明不清楚，对不起

例如使用数组查找方法

  var obj=this.fileArr.find(x=>x.FileVolumeNumber == "E312534.2" && x.FileNumber == "E312534");
  if(obj)
  {
    alert(obj.Type);
  }
