需要從Javascript中的Parent對象訪問Child對象的數組

Question

PostResponseOutput(TextedValue):Promise<any>
{
var options = {
    method: 'POST',
    url: 'http://NHSSQLCHNE8105:8081/ctakes-web-rest/service/analyzejson? 
pipeline=default',
    headers: {
        'Accept': 'application/json',
        'Content-Type' : 'application/json'
    },
    body: TextedValue
};
await request(options, callback);
async function callback(error, response, body) {
    if (!error && response.statusCode == 200) {
        var info = await JSON.parse(body);    
}  
}}

使用npm請求，我得到json的主體，並使用JSON.parse（body）將下面的JSON文件轉換為對象列表。 我需要訪問子對象中的數組。 但是由於子對象是根據我們提供的輸入動態更改的，因此無法在代碼中獲取子對象的數組。 任何人都可以在不訪問Child對象的情況下幫助從父對象獲取數組。

我需要刪除動態更改的子對象，並需要從父對象訪問其數組。 注意：PARENT OBject不會根據input進行更改。 根據輸入是否具有值

JSON文件

{

Admit
    "Allergy": {},

            "preferredtext: Hospital admission"
        ]
    },

// This is the SignSymptomMention Object. which doesn't have any Value for

// This is the RouteAnnotation Object. which doesn't have any Value for the

Value  for the input Admit
    "RelationDetails": {
        **"RELATIONS:":** [
            "\n"
        ]
    },
// This is the TimeMention. which doesn't have 1 Child object Value  for the

    "TimeMention": {},
// This is the ProcedureMention. which doesn't have 1 Child object Value  for 
the input Admit
    "ProcedureMention": {},
// This is the StrengthUnitAnnotation object. which doesn't have 1 Child 
object Value  for the input Admit
    "StrengthUnitAnnotation": {},
// This is the Health Care activity Object. which doesn't have 1 Child object 
Value  for the input Admit
    "Health Care activity": {
        **"Hospital admission":** [
            "start:1",
            "end:3",
            "polarity:1",
            "[codingScheme: SNOMEDCT_US, code: 32485007, cui: C0184666, 
semanticType: Health Care Activity, tui: T058, preferredtext: Hospital 
admission]"
        ]
    },
// This is the AnalysisText object which doesn't have 1 Child object Value  
for the input Admit
    "AnalysisText": {
        **"AnalysisText":** [
            "admit\n  ",
            "admit\n  "
        ]
    }
}

我已加粗**子對象，這些對象將根據輸入而動態更改。 目前，我已經將Admit作為Postmantool中的輸入

Answer 1

您可以使用Object.values檢索所有子對象值，而無需知道鍵。 這將是所有子項的所有值的數組。 因此，對於您的對象，您可以使用以下命令訪問數組：

 let Admit = { "Allergy": {}, "Others": { "Health Care Activity~T058~Hospital admission": [ "codingScheme: SNOMEDCT_US", "code: 32485007", "cui: C0184666", "semanticType: Health Care Activity", "tui: T058", "preferredtext: Hospital admission" ] }, "AnatomicalSiteMention": {} // etc... } let othersObj = Admit.Others // children will have all the values of `others` children // you don't need to know 'Health Care Activity~T058~Hospital admission' let children = Object.values(othersObj) console.log(children[0]) 

您只需要小心一點，就知道可能有多少個孩子。 的about假設只有一個，因此我們可以使用children[0]訪問。
