Javascript 我如何访问；订单“；在这个JSON中（名称中有分号）？

昨天被问到了，但在他得到答复之前就关门了：

HTTP响应：

      }
    }
  }
}

var json = response;
var order = json.object.entry.content['m:properties']['d:Order']; // I intend to read Order no from the below response.

Javascript代码：

  "entry": {
    "@xml:base": "https://API_PROC_SRV/",
    "@xmlns": "http://www.w3.org/2005/Atom",
    "@xmlns:m": "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata",

    "content": {

      "m:properties": {
        "d:Order": "123456789"
      }
    }
  }
}

var json = response;
var order = json.object.entry.content['m:properties']['d:Order']; // I intend to read Order no from the below response.

"TypeError: Cannot read property 'entry' of undefined

错误（例如jsbin.com）：

{
  "entry": {
    "@xml:base": "https://API_PROC_SRV/",
    "@xmlns": "http://www.w3.org/2005/Atom",
    "@xmlns:m": "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata",
    "@xmlns:d": "http://schemas.microsoft.com/ado/2007/08/dataservices",
    "id": "https://API_PROC_SRV/A_Order",
    "title": {
      "@type": "text",
      "#text": "A_Order()"
    },
    "updated": "2020-02-29T07:33:28Z",
    "category": {
      "@term": "Type",
      "@scheme": "http://schemas.microsoft.com/ado/2007/08/dataservices/scheme"
    },
    "link": [],
    "content": {
      "@type": "application/xml",
      "m:properties": {
        "d:Order": "123456789"
      }
    }
  }
}

var json = response;
var order = json.object.entry.content['m:properties']['d:Order']; // I intend to read Order no from the below response.

根据，响应是有效的JSON

json.object.entry

显然是错误的。。。但是

问：当

m:properties

和

d:order

在名称中都有分号时，访问“order”值（名为

d:order

）的正确Javascript语法是什么

注：我提名维杰的原始问题重新开放。。。但我并不乐观。这就是我的新问题。

您需要解析JSON。任何地方都没有

对象

属性，它是jut

json.entry.content

控制台日志（订单）你所拥有的似乎是正确的。不确定
对象在那里做什么。请尝试
json.entry.content['m:properties']['d:Order']
。您所做的似乎是正确的。不确定

json.entry.content['m:properties']['d:Order']
。
