Question

我正在尽力访问此大型JSON对象的特定属性。当我使用JSON.stringify输出对象时，该属性似乎在那里，但是当我尝试通过代码访问该属性时，它说未定义。我不太明白为什么...？也许我的知识库中有一个漏洞。你能帮我解决这个问题吗？非常感谢。

当我输出this.props.currentBuilding.apartments [0]时，我得到了这个JSON对象

{
  "Id": 1341394,
  "PlutoId": 13684,
  "Borough": 1,
  "Block": "00837",
  "Lot": "0036",

  "NeighborhoodFull": "Midtown-Midtown South",
  "lender": "MANUFACTURERS TRADERS TRUST COMPANY",

  "ParentCompanyName": null,
  "ParentCompanyAddress": null,

  "image_url": ""
}

我想访问此对象中的address属性，但是很遗憾，我无法做到这一点。

我希望只在该对象中输出address属性。

JSON中的属性名称区分大小写。地址属性为地址（大写字母“ A”）。

this.props.currentBuilding.apartments[0].Address
                                         ^

如何访问大型JSON对象中的指定属性？
