从JSON对象获取特定值

Question

我无法从JSON对象获取值。

我在JSON.parse() response和soap库获得的XML request上使用了xml-js。我必须获得的值是“ P01”。 这是JSON对象：

{  
   "Soap:Envelope":{  
      "_attributes":{  
         "xmlns:Soap":"http://schemas.xmlsoap.org/soap/envelope/"
      },
      "Soap:Body":{  
         "ValidateUser_Result":{  
            "_attributes":{  
               "xmlns":"urn:microsoft-dynamics-schemas/codeunit/UserValidation"
            },
            "return_value":{  
               "_text":"P01"
            }
         }
      }
    }
}

Answer 1

这可以解决问题。

const data = {  
   "Soap:Envelope":{  
      "_attributes":{  
         "xmlns:Soap":"http://schemas.xmlsoap.org/soap/envelope/"
      },
      "Soap:Body":{  
         "ValidateUser_Result":{  
            "_attributes":{  
               "xmlns":"urn:microsoft-dynamics-schemas/codeunit/UserValidation"
            },
            "return_value":{  
               "_text":"P01"
            }
         }
      }
    }
}
console.log(data["Soap:Envelope"]["Soap:Body"]["ValidateUser_Result"]["return_value"]["_text"]);

Answer 2

var o = {  
   "Soap:Envelope":{  
      "_attributes":{  
         "xmlns:Soap":"http://schemas.xmlsoap.org/soap/envelope/"
      },
      "Soap:Body":{  
         "ValidateUser_Result":{  
            "_attributes":{  
               "xmlns":"urn:microsoft-dynamics-schemas/codeunit/UserValidation"
            },
            "return_value":{  
               "_text":"P01"
            }
         }
      }
    }
};

var val = o['Soap:Envelope']['Soap:Body']['ValidateUser_Result']['return_value']['_text'];

console.log(val);
